I would by 10% and reset to 1 minute flight time just be safe.


Man after 60+ years of running IC, having to learn everything all over again is, well FUN!   Thanks, I am going to do just that!

No kidding...lol Be ready though, as you said the timer is supposed to detect cell counts so reducing the value could reduce the rpm, please let us know how it goes. 
My purpose in life is to serve as a warning to others.

Crist Rigotti runs the same rig I do and he thinks it will not affect the RPM's too but alas, we may never know.  Turns out that the 6s that I have are equipped with XT-60's and the ship in question has Deans.  Such is life.

I didn't think that it changed rpm, but you seemed to indicate that it did when you switched before.  Easy to check with a tach, 5s and then 6s and then not waste flying time at the field.  The adapters would make it possible to  check and see what you get before investing in batteries or changing plugs.

When I started with the Fiorotti timer, I tried a Castle ESC.  It worked in the sense of powering up and flying, but the response was too slow for changing rpm, so the acceleration and deceleration were slight behind needed.  It worked at a sport level, but not for competition.  That is a basic problem for accelerometers.  It will likely take someone trying it to find out, but my guess is that it will be too slow.  On the other hand, the price is not bad for a trial.

Programming looks to be RC transmitter only at  least for now.  Some of the brands share programming cards, again found by trial and error.  In the print, the seller say that multiple parameters can be set by remote control and then the defaults can be restored by remote control, presumably meaning RC transmitter.

Just hoping someone might know if a Fiorotti is DOA if it no longer sends an arming signal to the ESC.  I am unclear whether this is hardwired or firmware.  I suspect it is hardwired on the circuit board so I am SOL but it is worth asking.  At least it can be used to test mount in a new plane along with the burned up motor I have.

In a fit of stupidity, I didn't check the plugs and got the power lead on the wrong pin.  At $90+shipping @ it may be worth trying to fix, if it can be fixed.

It is a shame that we can't make the cable connections "fool proof".  It really isn't that hard.

Can someone who actually uses Fiorotti Timer tell me if there is possibility to adjust braking intensity independently from acceleration? The goal is to make braking to kick much earlier and harder than accelerating.
Thanks for your input!

I don't think there is.  There is only one setting for sensitivity.  I have to admit, it would be nice. I have two places that the brake kicks when it shouldn't.  The 4th corners of the Wingover and the Hourglass.  If I hit them hard the motor nearly stops for a split second.  I just live with it because it is not causing any real problem.

Please make that ASAP. Standard symmetrical adjustment of sensitivity is not enough, because some people (like me) doesn't have quick reaction and therefore require much more time to control trajectory in the bottom part of maneuvers.

I don't have anything to do with programming the timer.  I am just a user.  Maybe let Fiorotti know your feelings.

Friends,

Decreasing the RPM_Max setting will solve most of the above cases. I can add two Sensitivity adjustments "Acceleration and Deceleration or Brake" without any problems. The current setting already has a differential where it accelerates more than it brakes with the same setting.

I got great help from Fred Underwood with writing the manual, my English is bad. Attached manual to help everyone.

I have been using Fioratti 6.5v and I am
Loving it . G force can be independently adjusted where as 6.4 the brake/Acc is equal.
Play with min setting and also go to esc Manuel braking to change braking strength and speed of brake plus
Using a higher c battery. Hope this help, cheers.

I am considering using a cheaper ESC for a project.  Will the timer work correctly with the BadAss 35?  The project will be a twin and the prospect of putting 2 Spin 33's in it has my wallet vibrating.

Oh - can someone answer Vitalis question in the last post?

OK, the wallet survived the Spin 33 dual ESC's.  Now I have a specific Fiorotti question that I have posed on other threads but I am hoping to get an answer from the Fiorotti community.  If you are using two ESC's in a twin it is suggested that the following be done:

#1 The On/Off switch for EXC#2 be left in the Off position permanently.
#2 The power lead (red wire) from the #2 BEC be cut.
Is this correct?  Inquiring minds want to know. And:
#3 Will the ESC or Timer be damaged if the Red Wire is Not cut?
#4 Does the Jeti box connected to the timer #3 set of pins (bottom set) get it's power from the center pin?

Ken
Oh - still waiting for an answer to Vitalis question below.  FYI I have one of the newer timers but have not used it yet.

I have a question about the G Force parameter settings?
With the version 6.5 timer there is adjustment for both positive and negative, The "I" and "D" values.
Which value controls positive G forces ? I want the power to increase more pull ups. (I find the instructions not very clear on this.)
Overhead power is fantastic with the nose up parameter. I just want to understand the timer more.
Also can anybody explain the G number in the top R/H corner? how and what does this parameter change?
Thanks :-)

You can have Increase (boost) and Decrease (braking) RPM at your set values.  On the older versions, there was one value, so the same amount of Increase and Decrease.  A good starting place is 5 for each and then adjust to your style.

The actual number for G-force, the value in the R corner, is calibrated when you fly in the first 3 -3.5 laps.  Flight should be level while calibrating, noted by a rapidly flashing light.  Recalibration is done in those first laps automatically if you change the set or base RPM.

In V6.5, you can manually set a G-force which will also be recalibrated back to the timer when changing set RPM.  IF you change the setting for G-force manually, then the timer will try to get to that setting and will adjust its rpm as needed, meaning that it may need to change your rpm even in level flight.  That could mean different lap time and battery usage.  My recommendation for now is to leave it to the timer to calibrate, don't manually set it.

I have an access issue for the accelerator pad on my twin.  I need access in order to level it but I have no access to the bottom of the plane near the CG.  If I mount it about 1-2 inches forward of the CG am I going to have setting issues?  I will have to cut an access hatch in the bottom of the plane otherwise.

Second question.  Normally my timer sits just in front of the wing on the inboard fuselage side and is pretty far from the ESC and other things.  In this one it is going to be right next to the esc and one set of motor wires.  Am I going to have interference issues?  I suspect not but I am far from expert in electronics.

I've flown another's airplane with the sensor in the ESC area, so, low in the plane and forward.  Another placement for the sensor was high in the battery compartment at the wing bulkhead accessable through the hatch.  I could not tell any difference between those sensor mounts and mine in the standard rear of the CG area.  I haven't tried other timer locations, but it doesn't seem like they would matter unless you get vibration, heat, or electrical interference enough to affect the chip. Seems like what you need should work.  Of course ESC type extensions to get Jeti box connection in a convenient area.

Another question, or perhaps the same question reworded.  I have always used ESC#2 on the timer for the Jeti box.  I run a patch cable from it to the side of the plane where I put the male connector through the fuselage flush with the side.  This lets me plug in the Jeti for programming without opening anything or taking anything off.  So now I have an ESC on the #3 set of pins so to program the timer I have to take that lead off and put the Jeti on then do the opposite when I am done.  Two opportunities to screw up.

What I want is a micro AB switch so that I can wire the ESC and the Jeti port and toggle between them.  Only one opportunity to screw up.  I can't find one anywhere.

I have been following the threads discussing Shark Week and one of the things that has bothered me about the Fiorotti is that I can't seem to get the cornering boost to come on while I am still in the corner.  It could be that the Spin Pro is too slow, or it could be that I am not setting one or all of the settings to produce it.  I want the boost to come on as close having reached the apex as possible.  Right now, I get it just as I hit the flat and if I am not careful, I will get a bump as it kicks in.

Will the timer work with a Spin instead of a Pro and would that make a difference?  Is there another ESC that is as fast as the old Spin?

Ken, could it be that the sensor is mounted too close to the CG ? If the sensor was mounted as far back from the cg as possible maybe it would detect more rotational movements earlier?
Just a thought 😁👍

And a good thought.  I have it mounted just forward of the CG.  From what I have been told that is where it should go.  I have another plane where it is mounted 6" behind the CG and it does the same thing.  I have also been told it doesn't matter much along as it is oriented properly and leveled.

On an old set of instructions for V4, the sensor was shown 30 - 40 mm behind the bellcrank pivot.  I could not do this in my first plane, a profile with the sensor in the fuse.  It ended up several inches behind the CG and pivot.  It worked fine, and I discussed it with Rogerio years back.  Since, I use similar position a few inches back of the bellcrank pivot for convenience.  I have flown a friends who tried a couple of different mounts, including inside the battery compartment at about the leading edge of the wing.  A very convenient positsion for any adjustment.  I could not detect a difference from mine, nor could he.  He also tried the original suggested position and could not tell a difference.  But, as they say, your mileage may vary.  Ken's word was probably from my mouth :-).

My understanding is that the sensor and timer are acting on nose up angle, acceleration for sensitivity, and force for G-force, not directly on rotation or rate of change of rotation.

I have communicated with Rogerio on the late boost out of a corner and he suggested leveling the sensor pad with the nose down a few degrees.  He says that should make the boost come sooner.  It makes absolute sense since most planes fly at a slight positive AOA in level flight. He also said that the programming knows the difference between upright and inverted with this change and it would work both ways. I hope it works. HB~>

Ken, This Idea sounds good, however to my understanding (I could be wrong) If the sensor is not level this would change the lap speed between upright and inverted?
It would be easy to flight test and figure out?

I asked Rogerio the same question in a different way and he implied that it wouldn't.  Even if it does, I would gladly sacrifice even lap times on the 6 laps inverted to move that boost further back in the corner.  Hope it works.

I have mixed results.  The change in the sensor did move the boost in corners back some but not as much as I had hoped.  I think only a faster ESC will get me where I want to be.  Lap times were about the same 5.4 vs 5.3 so there was a small change but that small amount doesn't bother me.  Air was so dead that I was getting wake turbulence in level flight. Overhead boost was the same.  Next stop is going to be the sensitivity setting.

Are you using the Fiorotti in "Agenda"?  Spin or Spin Pro?

Fiorotti, Spin Pro.

Next timer will be Igor's new one with a Spin 66.

I flew my Trifecta in a contest today and experienced my first IC like day with a timer.  It all started when I got hammered into the ground on the second Triangle of my first official of the day.  The plane was banged up but flyable.  From then on I was getting boost where I should have brake, massively different inverted and upright speeds and boost on the backside of rounds.  Anything over 45 was fine.  The sensor on the timer has calibration settings that tell the timer when it is flying level.  If they are off then lap times will be off and/or inside/outside turn RPM's will be unequal.  Assuming the sensor has been leveled and the calibration laps flown, what else could be wrong?  I have checked the videos of the plane and its AOA in level flight is just enough tail low create lift.  Although I doubt that the timer's neutral setting takes that into account it would not be enough to cause what I experienced.  Can timer or ESC settings be changed by smacking the plane into the ground?  This was a dramatic drop in RPM between level and inverted and a similar drop on outside turns.  Almost like it was trimmed with the sensor setting reversed (it wasn't).  It will be interesting to see what the settings are after the NTSB investigation.

Are you using G-Force?

Yes.  It was working perfectly.  Over 45 the plane was a well trained showdog.  One possibility is that the sensor was way off.  Best we could do at the field was eyeball and I got second opinions.

Does anybody have the default settings for the latest V.6 timer?  I was programming it for my twin and got lost trying to figure out the brake and g-force settings which are now separated into what I guess is (D)ecline and (I)ncline.

Second question is just what is "X" on the sensor pad values.  I know "C" is factory level and "Y" is fuselage level, I am assuming that is the nose to tail axis.  So what is "X" and how is it set relative to "C".  I can only guess that it is the wing tip to wingtip axis, of something completely different. I wish I had the time and writing skills to write a "Fiorotti for Dummies" manual.

G-force is self setting for the actual G-force number, though you can manually change it.  G-force needs to have either or both D and I to have a value, then it will calculate the G-force and show its on the screen.  If D and or I is on, the G-force will calibrate and show the new number when you change the base RPM.

If you want to check the sensor settings, you need a level pad, or a place where you can level the plane accurately, and that includes the mount in the plane.  The C number is factory set.  It has to do with the electronics of the sensor, so the C is matched to the sensor.  C and Y may be slightly different for different timer sensor pairs.  If you haven't changed C, then Y should equal C when all is level along the fuselage length or pitch axis, as you stated.  Y should match C very closely, usually within 1, maybe 2.  X is less critical and a value is not stored, nor is it related to C.  If you have a level pad, or the plane level along the wing/roll axis, you will see X.  I try to record the X, Y and C numbers checked on a leveled pad before install.  Then I can check to make sure that nothing has changed.

If you crash a timer sensor, then you might want to check to see that Y and C are still equal.  If a crash changed the value, I suspect that more would be wrong than a shift in the sensor C/Y.

I hope that helps.  I will try again if not  :)

Fred:  Does the timer save two values for "Y".  Upright and inverted.  If there is only one value for "Y" and you get it perfect upright then flip it over and match it inverted you have changed upright.  That one still has my brain twisting.

One C value is saved for Y to match.  Y upright and inverted are still both level without positive or negative pitch.

I have a question for the Forotti timer experts ?
So far I have 110 flights on my setups so far, overall very happy.

On my last day out at the field after 3 flights, On the 4th flight my level flight lap time suddenly changed! I went from 5.2 lap time down to 5.7 lap times!
Overhead boost was still working as per normal but level flight had slowed down.

My first thoughts were that that I put a flat battery in, but I checked it was a fully charged battery? I checked over the model very carefully. The sensor had not moved and the air frame was sound. No damage to esc or motor?
So I put a new fresh charged battery in and same result? Slow flight at 5.7 lap times?

I looked through the settings on the timer and everything looked normal, until i got to the G force settings. The G Force setting looked like it had changed by its self? the setting in the top r/h was at 1.75g From memory this setting was closer to 3g ?? but i'm not 100% sure as I did not record my base line settings.

Has anyone had anything similar happen? or thoughts on why this happened.
Thanks :-)

One thought.  Did you do anything that would have caused recalibration?  I had a similar issue at a contest where I had a rather harsh landing at the bottom of a square on my first official and dislodged the sensor.  I leveled it as best I could but evidently I didn't get it even close.  It was a disaster.  It was like everything was opposite. I managed to get through the pattern, but it was a nightmare with a score to match.  On the next event (Classic / Profile) I forced a recalibration on my first flight, and it was at least flyable.  It sounds like something changed that needs,  but did not force a recalibration.  Is it acting the same upright and inverted?  That will tell you if the sensor is level and if it is, you may need to adjust your base RPM to get your lap times back.  Also, I have found out that recalibrating in anything over a mild breeze can cause G-Force to act strange.  Hope this sparks some thought, and you find the issue.  When they get out of adjustment, they can be a real hair puller!

Ken

Another thought.  Where is your low voltage cutoff set in your ESC?  When I switched from LIPO to Li-Ion I forgot to change it from 3.2 to 2.7 and had a similar problem.  Also the low rpm could be too low in the timer.  Just another straw to grasp at!
