acdii, how are your ailerons wired? Did you use a ''Y'' harness or use individual channels for the aileron servos. If you have the channels you might want use different channels for each aileron, mix them, and then program them to raise up when you flip a switch. This will allow you to use them as spoilers instead of flaps. Just a thought.
I'm flying on a DX8 right now, but also have a JR 12X. I am giving thought to swapping out radios and putting in an 8 channel RX so I can do just this. I cant do it with the current RX since I am using up all 6 channels, 3 are just for the engine, Optikill, choke and throttle. I could use the 8 channel RX with the DX8, but starting to have concerns about the radio power supply. I had a Turnigy Lipo pack in it that died on me, thankfully not while in use, and the original NiMh pack seems to be OK, but the voltage after a fresh charge, according to the radio is 5.4 and drops to 5.1 after 15 minutes. I did a discharge/charge cycle on the pack and it did very well, so I dont think its the pack.

I also have a Futaba 8FGS and either a 7 channel or 8 channel RX laying around, now that I think about it, I should have the 8 channel one it came with, and I have one I picked up, I think a Fyresky or something like that. I use the Futaba for my LT40 and since I fly that plane the most, its the most familiar radio to me, so I may just move to that radio instead. I have 3 RX for it, and I have 6 or 7 RX for the Spektrum/JR, so a toss up on which one to use at this point. I think I will feel them out and decide. I noticed I have to search for the flap switch on the DX8 when flying the T-34, so I will see how easy it is to find the flap switch on the Futaba and JR and that will help make the decision. The JR is a nice radio, but for the price you would think it would have a SD card or something to store models on. If it does I havent found it yet.


I have been kicking around the thought of flaperons on this to help slow it down, especially after doing a couple landings with the T-34 with flaps. Once they got setup correctly(thats a story in itself) I was finally able to put it down on the mains and not the nose wheel. Before with no flaps, when I tried to bring the nose up a hair to flare, it would either drop, or balloon up, and with the flaps now, it comes in with the nose up like it should. And this was supposed to be a trainer! I guess there is a reason this particular plane came with flaps.

acdii - you have all the radio you need in the DX8. Do you have dual aileron servos or a single servo? And if dual servos, are they on a "Y" harness?

You'll need dual servos and your 8-channel receiver, then just program your radio to move the ailerons in the desired direction on the flap switch and you'll all set. You'll be able to reflex the ailerons or make them flapperons (which ever you decide) at the flip of a swich. Heck, you can even program the flap switch to reflex or drop the ailerons depending on which way you move the switch (My Stryker moves the rudders as airbrakes either in or out depending on which way I throw the flap switch).
