Question

Spectrum AR500 and flaperons…


I'm nearing completion on an Arrow Legend and plan to fly it on 2.4 ghz. To that end, I purchased an AR500 RX thinking it would give me proper flaperon function. A flying buddy told me today that the AR500's aileron channels are simply Y-harnessed internally and that the RX would not mix flaperons.

Apparently he was right. I just powered up the Legend wing to center flaperon servo arms and noticed that the servos work fine as ailerons, but when I checked the flap function, the aileron surfaces still moved opposite of each other. Not good…

Has anyone else had to deal with this glitch, and if so, what's the work-around? I'm using the X9303 TX and an Arrow setup copied from my old 72 mhz. 9303. Didn't someone here do some testing of the AR500 and find it OK for flaperons? HELP!

Problem solved…


Made a quick call to Dave. Feeling really stupid right now. Do not use the two aileron slots on the AR500; they do not give you split ailerons. Use the THRO and the AIL slot closest to the short antenna. Everything works perfectly. A tiny detail the guys at JR/Spectrum neglected to include in the Idiot's Guide to using this thing.

Mark,
If your transmitter is broadcasting (aileron)flaperon functions on channels 1-2, why wouldn't you have tried it on channels 1-2 on the RX? Aren't your other planes that use Berg 4 channels set up the same way?

I too can't get flaperons to work with the AR500... How would you use the THRO as an aileron? Where would you plug in your throttle then.... I've also heard to use the 'gear' as one of the aileron plugs, but I haven't had much luck with that either. I think we need AR6200's...

I flew DLGs all last year on AR500s. Use the first four plugs and ignore the extra aileron port...

Easy peasy on the 9303... next to impossible on the DX7

Agreed...now that I figured out the sailplane programming. I'm using an AR500 and plan to use a couple more in the future.



Tom, I pm'd you so as not to hijack someone elses thread. It's probably relevant to this though.

On a 5 channel receiver, That's 5 seperate channels , none tied together inside the receiver, if you have the ailerons moving in the correct direction, but the flaps go up instead of down, I have "always" been able to correct that by just swapping the two aileron connectors at the receiver.

Try it,

Walt,

With the AR500 there are 5 separate channels, but 6 servo ports. The 6th port is labled as an Aileron, but is just a "Y" of the main aileron port.

Earthling, it all depends on which transmitter you have. As Tom said, with a JR 9303 it is easy in Glid mode. With a Specktrum transmitter, I've heard it can be done, but it's not easy. It's easier to buy a 6 ch. receiver.

Thanks Brian, My fix won't help if you have two ports that are paralleled together. That's so, not cool to me. otherwise some day you will/ may need my fix.

Actually Walt, your "fix" should work fine as there are 5 independent channels plus 1 tied to the ail channel but it is a 6th plug at the end of the rx. I was able to program my DX-7 to use channels 1-4 and have flaperons work for my Blaster2 DLG's. I did this because of the failsafe only being available on channels 1-3 on the AR6250. Shortly after I figured out how to make that work I switched to a "hacked/frankintransmitter" using my Evo-12 and a Spektrum module. That made assigning the channels very easy. So for your fix to work there would need to be an aileron mix to either channel 1 or 5.
