Who is ging to have a new 2.4 plane this season?
« on: December 03, 2012, 05:00:36 PM »
Are you going to try 2.4 in a new (or old) plane this coming contest season?  Let's hear about them, with pictures if possible. I have two ready, but testing remains to make the determination as to which one or maby neither.

No new planes, but all the old ones will be retrofitted, already have the profile and  one scale converted.

I am building an electric Seafire profile , and a class I electric Vickers Vireo, with 2.4ghz. I have already converted all my existing  electric carrier, scale , and sport planes to 2.4.

If I build a new glow plane I probably will use 2.4, but I think I'll leave existing glow planes alone.

What happened to the other thread on this topic?  I thought there was already some pictures and initial test reporting.

I have showed these pix before, but here is the Profile MO-1 that I retro-fitted with the 2.4 system, the handle conversion and a shot of the airborne components with a 9v battery for size comparison.  I have a couple of short flights on this and the throttle response and 'feel' are pretty much the same as a 3-line system.

I am finishing up a kit-copy of the Sterling Hellcat (with a 41" foam wing and the fuse and tail parts directly traced from the kit parts).  It will serve as an engine testbed, radio installation testbed and contest backup plane, most likely.  The radio parts except for the top of the servo will be buried in the wing.

Should be ready for picture taking later this week, and if the weather hold maybe even get flown yet this year.

My profile Seafire for 2.4 GHz has been started, not much more will be done until after the holidays, it is patterned after my very successful electric 15 Seafire. Construction is all foam except for a bit of ply for doubler's and some carbon fiber tube.  The foam is 3/8 pink insulation. No slider is planned, the 15 hangs OK without one, so I hope the 35 size will too. For high speed I plan a motor capable of 1-1.2Kw. slow speed(hanging) should use about ½ this power.  Throttle will of course be 2.4 GHz.  I plan to make a handle as Mike and Bill have, but haven't gotten around to it yet.

Starting on a new Bischoff Zero for Profile. Will have at least 2.4 throttle and slider release.

In case you have been wondering, the first picture with the Micromiters as clamps was a joke.
The second picture is no joke, I needed a small clamp in a hurry and the only thing on the table was the mic and one small clamp.

Was a my brother's today and asked him if he still had that McCoy 60.  And my best friend and wife got me a 2.4 - 3 channel radio for Christmas.  TADA, now I have a reason to build the Sterling Guardian kit that's been sitting for a couple of years.

Just a reminder, Nostalgia Carrier specifically prohibits electronic controls. You are good to go in "modern" carrier.

Finally got this far enough along to take a few pix.  This is also Sterling Hellcat based with a foam wing and the rest of the parts traced from the kit parts, except for the plastic canopy that the kit features.

Radio installation uses the same low-cost Hobbyking receiver/servo as the MO-1 above.  I did buy some extra receivers and servos and had no trouble with binding the new receivers to the transmitter.

I stuck the radio in a cutout in the foam on the bottom, with a plastic cover screwed over it.  The battery is underneath the receiver in the shot below.

Also I will be using a slider which I haven't yet worked out, but will also use the direct connections to the bellcrank that Bill has shown.  One word - I first set it up with a Sig 3 inch nylon bellcrank and then decided I had better pull test it.  At about 35 lbs, the plastic bellcrank started to fold up, due to the offset load (due to the monoline buttons).  If conventional leadouts were used, threaded through the bellcrank, I'm pretty sure that the plastic bellcrank would be OK up to the normal 20g pull test.  Anyway, I went with a Fox aluminum crank - which I pulled to 90 something pounds with the buttons.

That of course depends on "local option announced 30 days prior to the event".

Mike, sorry to stray so far off topic, but here's what I do with Sig bellcranks. The clips are bent from .045 music wire. I've been using this setup on WWII slow combat planes with good results.

     Here is my latest e-15 plane. I built it to replace the e-15 plane I've been flying the last 2 years. The first  plane was built to take full advantage of the e-rule that goes by weight to prove that the allowance of 40oz was to much. This plane weighs in at 28oz ready to fly on my scale which may be weighing on the light side so lets say for sure it is under 30oz. The 40oz plane was scoring 280+ and it looks like this one will come in somewhere in the 240 to 26o range. The current battery capacity allows for a fast HS and a so so LS or a so so HS and a better LS so depending on contest conditions I would have to adjust how I fly the plane.
    First picture is overall plane, 28" built up wing with 1"tips for a 30" span, carbon fiber tube fuselage is 24" long over all, and the next biggest thing is the wheels which are 2.25". Next picture shows front of plane with openings for cooling batteries. The battery's really don't need to be cooled because there just isn't that much draw on the battery's. Next is the bottom mid section where all of the "stuff" is shoved in to run the plane (empty).
     Next here is the mid section full of the "stuff". Castle icelite 50 ESC, Spektrum SR 3500 receiver, and 2 TP2250-2SPP65c batteries. The motor is a Scorpion HKII 2221-2010KV driving a Zinger 7/4P pusher prop. Last picture is buttoned up mid section ready to go flying. The pictures are attached in the next reply because I attached the first picture wrong and don't know how to correct it, oh my.  Eric

Hi, Bill.

Great swivel effect at that Sig Bellcrank with the .045" wire... Do you just use large (.095") eyelets at the terminated ends of the control lines to hook onto the doubled .045" wire ends?
(do the control line cables preclude the need for lead outs is what I'm asking)

I make sure the line eyelets are big enough to fit the clips, and hook the lines directly to the bellcrank.

Eric,
Very nice 15E. Am I reading that right that you are only using a 2s battery?

     I am using 2-2s batteries in series to equal a 4s battery. I've sort of settled on 4s as the size of battery that I can work with in the planes I build and fly. Enough room in the CL plane's fuselage and in the Profile's I can use 2-2s packs and split them up in the leading edge area of the wings. I'm a big believer in low frontal area as an easy way to pick up less drag right off the bat on any new plane. I figure if its not there I don't have to try to steamline it.
     The biggest draw back I saw was when you split a battery I was told that I would have to be very careful how I charged them and would need a special charger and some y-connections to do it. Well I bought a special charger and made some y-connections and then tried to hook it up and couldn't because the balancer would not let me. I've noticed when charging batteries that the cells rarely take the exact charge value so what was all this talk about. So I just bought 2-2s batteries and charged them up as close as I could and plugged them together and guess what, no smoke, no heat, no variation in how they discharged, ect..
     The only draw back that I see is that you pick a few grams of weight with a few more plugs, I can deal with that for now.  Eric

Eric,
I have two field chargers that will charge two batteries at a time through the balance plug. However my strategy has been to have two sets of batteries for each contest plane, seldom do I charge at the field during a contest. Also it sounds like you are leaving the batteries in the plane to charge. I always pull them out and charge in a fireproof container.

I like your design philosophy, going with 2-2s batteries gives a lot more installation options.

     No John I don't leave them in the plane to charge, I take them out. I never (as yet anyway) charge at the field because I'm afraid of running down my batteries (Dodge diesel) or I don't want to hang around at the front of the truck while they charge or I'm usually out there to try something out and when I'm done I want to go home to figure out if I'm satisfied with the results. I charge them at home in my model building room inside my house using a bomb bag and watching the balance while charging. This to me is the biggest draw back for electics, the type of battery we are using and the careful charges we have to put into them.
     The plane is easy to work on as I turn it over and open one velcro latched hatch and there is "everything" ready to be taken out, charged, and put back in. Each electric plane I build I try to improve how the components are installed and taken out and how well I can tuck in and hide those ugly darn wires.  Eric

Eric,
I am lucky at my field to have AC Power. So if I want to charge I can easily with my 110v charger. I have a flight bos with a couple of gel cells for field charging when away from my home field, Charging is slow but sufficient. I agree that hiding the wire is a headache, Full scale planes are easier, but profile tend to get messy.

I am building a new Zero for 2.4 ghz to see how competitive it will or won't be. One thing I decided to try was using a micro servo to release the slider. The installation is very simple and the weight penalty is about 1/4 ounce. No more worries about dropping the hook on takeoff and releasing the slider!

The servo is built into the wing, and is more or less permanent. There is no load on the servo, so it should last forever. It is now covered by a scrap of foam and sanded flush with the wing, but a picture of that doesn't show much.

The receiver will be installed in the front portion of the wing near the root, and the battery will be in the outboard tip. I will use the same throttle linkage scheme as on my recent Hellcats, except connected to a servo rather than the bellcrank.

Sorry to resurrect an older topic, but I just finished my new plane yesterday. We have a contest next week, then I'm going to the Iowa contest the week after, so I'm hoping I can get a few flights on it tomorrow or next Friday.

This is my first dedicated 2.4 airplane. I posted a picture of the wing earlier in this topic. The throttle servo is on the "clean" side of the airplane, along with a throttle linkage through the fuselage. The servo operated slider release looks like it should work great. The airplane was originally solid gray, but this revealed too much of the wing's foam texture. I disguised it with the splotchy green finish that only added seven extra grams. I think it is more visually interesting than either solid gray or solid green, and didn't require any masking. I'll be doing more like this for sure. The wings are covered with silkspan then SLC, and the finish is Klasskote epoxy. Weight with the Wiley 36 is 43 ounces.
