....OK, folks...been out of this for awhile and am trying to program a JR8103 radio for an Ultra Stick 40 ARF with the full flap setup.

Read KeithB's suggestion that follows in the thread on this page titled Hanger9 US60ARF. (Thanks, Keith!):

I don't know why they haven't clarified this in the manual yet. I went through the same thing. Here's an addendum that I got from Horizon Hobbies for my US 40.

Actually, the way it works is a bit questionable in my opinion because you don't have control over how low the take-off flaps go, however, I don't really use takeoff flaps anyways so I'm happy with having the crow work.

Hope this helps.

Addendum to 8103 Program for Ultra Stick

1. Go to function list
2. Highlight D/Flap T. and hit enter
3. Activate Pot 6
4. Return to function list
5. Put your 3 position flap switch in the bottom position
6. Select Program mix 5 or 6 (whichever is empty)
7. Set flap pot at full negative value
8. Select Offset and press “clear/store” (value should be –222)
9. Go back to function list
10. Select D/Flap T.
11. Set pot 6 to “inh”
12. Return the flap switch to the top position
13. Go to your flap mix and set the rate until your ailerons are level
14. Have fun flying your Ultra Stick!

But I haven't been able to even get that far.

Now, with all switches off but the flap mix switch in the middle the ailerons/rudder/elevator/throttle work as they should and I could probably fly the plane this way.....

BUT.... when I put the flap switch up, the flaps go down solid and the ailerons work fine.

With the flap switch down the flaps go up and stay.

Now, when I throw the program mix switch forward and the flap switch in the middle, the ailerons are coupled and follow the ailerons fine....one big aileron, yes...so far no too bad.

But when I throw the flap switch down with the mix switch forward the flaps go up, the left aileron goes down slightly and the flaps follow the ailerons in this strange, out-of-alignment position

Sigh...

I EM'd Horizon a couple of days ago about this but no reply yet. I read the manual in the bathroon at work and every thread I can get my hands on but I am missing something!

I think it has to do with the mixing, i.e., flap-to-aileron, aileron-to-flap, one I created on mix #6. Which mix, or too many, perhaps.

Sorry for the long post guys, I'm an old analog guy and this new digital goes right past me.

Can anyone offer a little step-by-step for this idiot that just wants to fly??

Thanks!
