If I change to a Spin 66 pro from a Castle do I have to keep the slide switch ? and push the button on the Fiorotti timer?

The timer starts with the button.  The switch can be left "on" and in the plane.  Taped in the on position so that it will not go off.  You can cut it off and solder wires together, or "on."

G-force is not restrained by the Max and Min numbers used for sensitivity.  As you suggested, G-force is around 3 normally.  G-force will try to force the plane lap time and acceleration to achieve the G-force.  Rpm for G-force will likely force slowing to reach the "desired" or set number but should have to stop at the limits set in the ESC.  So, it was continually in action to slow the plane trying to reach the 1.75 eveen level flight.

Most G-force errors are mistakes in setting.  At least mine are.  I actually haven't flown with the error, but have done it a few times and caught the mistake.  I am very carreful on when on the G-force screen.  When you scroll through the functions, it is easy to go up or down when the cursor in on G-force and change the number when you wanted to advance the cursor to Decrease or Increase on the same screen.  If this happened and you are sure that you haven't changed anything, or are sure that you haven't attached the Jeti Box just before the G-force change, then perhaps a malfunction.

G-force will recalibrate with a set rpm change.  You can change the RPM by 1 up or down and it will recalibrate.  There is a forced recalibratation as well.

To carry out the recalibration when without RPM change,
press and hold the START button to begin the flight
(instead of the usual press and release) until the LED
flashes quickly

Please let us know if you figure it out or solve the problem, or not.

I am going to do what I thought was unthinkable, I am going to disagree with Fred.  I am currently building a twin with two Spin 33.  I was concerned about having two esc's on the single battery and what I should do about the switch.  Should I wire the on/off switch to a single switch or as some suggested just short them and let the arming plug power things up.  So I did something totally our of character, I asked Jeti.  The answer I got was to not bypass the switch.  It only provides power to the timer and it needs a few milliseconds to charge the ESC properly before it is ready to communicate with the timer.  They also said it could cause damage to the timer or improper initialization which is probably more to protect them than us.  I have seen it improperly initialize when I forgot to turn the switch off and changed batteries.  The timer refused to start.  It acted like it armed but it didn't.  Turning the switch off then on fixed it.  I know a lot of people leave the switch wired on but I don't anymore.

This is another item that should be in the set of instructions.  I find it unbelievable that the set of instructions that come with various timers are so incomplete.  It's been 6+ years now and still no complete instruction manual for this timer.  I'm guessing the designer just doesn't want to put the time into it.  Unbelievable.

No problem with disagreeing :-).  Jeti knows what is best for tghe ESC, and maybe more so for 2 ESCs.  I have many flights with the switch taped "on" and out of reach, and then removed the switch on the next plane.  I have not seen a problem with the ESC or timer, but perhaps I am fortunate.  I know others have done similar.  For the timer to function, it needs to be cycled off, no battery connection or perhaps a switch off and on, and the button then pushed.  If you push the button to stop the motor, the timer will not restart (should not and mine hasn't) with a button push without the cycle of no battery connection.

The latest update of the Fiorotti timer manual that I'm aware of was noted earlier in this thread, linked below.  A PDF for download.

Thanks for the link.  I just read the entire manual and it is an improvement.  However one item has me confused.

"Note that with either option the wiring must run toward
the model nose and sensor should be aligned parallel to
the fuselage."  Where does the wiring start?  Timer or Sensor?  If it is at the timer which is logical then the sensor needs to be in front of the timer which is not logical.  Does this imply the the sensor wires need to stay parallel to the fuselage as well?

The more complete manual quote is

Sensor Position:

You have 2 options to install the sensor:
Normal – Sensor flat side pointing down.
Reverse – Sensor flat side pointing up.
To change option press START.
 
Note that with either option the wiring must run toward
the model nose and sensor should be aligned parallel to
the fuselage.
 
If the installed sensor position is inverted from its
functional position, your accelerometer will not work
properly and you will notice that the light continues to
flash even after landing, until the battery is disconnected. 
You will need to change the sensor position setting.

Thanks for comment and opportunity to clarify.  The heading for your quote is about sensor position.  The wiring needs to point toward the nose as it leaves the sensor.  Between the sensor and timer, the wiring can be lengthened, shortened, or positioned as needed.  The sensor is oriented properly front to back when the wires exit toward the nose.  This is necessary even if you have the sensor in the nose ahead of the timer.  Though that positsion is not suggested in the instructions, it has been done and worked, when the wires exited the sensor pointed forward, and failed when the wires exited the sensor pointed back toward the timer.  The wires should be restrained at sensor exit so that if the length of wire shifts, it does not move the sensor.

Last weekend a friend of mine drove a long way to an out of town meet and had his plane destroyed on a practice flight by a prop strike.  I have lost two the same way.  Short of using the self-balancing BadAss props (see pic, yes it kept flying) is there anything we can do with the Jeti-Fioretti combination to achieve at least some protection.  I have lost two the same way - prop strikes, breaks a blade, motor keeps running and vibrates the nose off of the plane.  I think the Jeti-Fiorotti combination is top drawer except for this rather serious flaw.  Most of what I want is in the Fiorotti so is there perhaps another ESC that has prop strike?  Using the Jeti box to maintain both is a big +, I would hate to give that up.

I'm not sure who offers prop strike protection.  I searched the 3 words timer prop strike in tshe forum search and found a lot of good information and explanations.  I started with KR, and it has protection, if you wait to launch until it reaches full rpm.  If you use a soft launch, as it spools, then no protection.  It looks like Climb and Dive also has protection, but I don't think the others do.  Many suggest using ESC features for protection, with some good explanations in the links from search.  Unfortunately, prop strike protection doesn't help to pay for the good carbon props :-).

Like the table saw automatic blade stop.

Question for people who are using the Fiorotti timer with Jeti esc’s ?
What mode do you run your ESC in?

Constant RPM (3d Heli)
Constant RPM Auto
Fast Response
Normal

I think most my tuning and setup issues have been with the ESC and not the timer, But keen to hear other’s setups?
Thanks :-)
