Default RE: Flaperons?

Sorry Combatpigg, but I'm going to have to continue to disagree with you here. First off, I've gone back and looked through the post in this thread (hey, it was either that or actually work, and I get paid either way) and I honestly can't agree that you have posted any truly helpful information to Iceman's initial question. Your first post was closest to it in that you were telling him how they work, unfortunately that was the post that started the whole argument:
Combatpig (Post no.3)
All you are doing is programming your radio to make the ailerons behave like flaps when you use the elevator . when you move the elevator up, the ailerons should go down. Make sure that your end point adjustments are accurate,if the flaps don,t move an equal amount you could be in for an interesting flight. Flaperons will open up your flight envelope, and they even saved a plane for me once when the elevator servo went out.
Since you were stating what your Futaba manual had to say about flaperons (see post No. 6), I decided I'd show what is in Iceman's manual concerning them:
Flaperon mixing (FP)
This function allows the ailerons to be used both as ailerons and as flaps. The flap control dial (CH 6) operates the flap
function. To use flaperon mixing both ailerons must be operated by separate servos.
To activate flaperon mixing:
1. Connect the aileron servo in the right wing to channel 1 (aileron) in the receiver
and connect the aileron servo in the left wing to channel 6 (flaps) in the receiver.
2. Enter the programming mode and access the W.MIX menu using the MODE key.
3. Push the DATA INPUT lever until FP is displayed on the screen. Now the mixing is on. The
servo travels will automatically be reduced to 60% and 40%, but full servo throw will still be
achieved when the aileron stick and the flap control dial are moved to their full extremes.
4. Once this mix has been activated, move the servos to their full extremes to make certain they are not overdriving the
controls. If necessary, adjust the linkages to achieve the correct control throws.
(If necessary, use the Servo Reversing function
to achieve the correct direction of servo throws.)


As you can clearly see, these directions do not mention the elevator at all. It does, however say that the function allows the ailerons to act as both ailerons and flaps. You saying that the ailerons go down when the elevator goes up has nothing to do with this function. What you are thinking of here is that when the flaps are activated, then the elevator is sometimes mixed in (with a completely seperate mix) to counteract the planes natural tendency to balloon up when flaps are activated.

As for you being the only one that has offered any help to his initial question, I have to disagree with that for another reason. As far as I've read (and I've read all of the posts at least twice now), I am the only one that actually took the time to look up his manual for his radio as well as his plane so that I could realize that the plane that he was wanting to use flaperons on couldn't actually do this in the stock setup. Then, when he mentioned that he was considering using seperate servos for each aileron, I was one of the two that mentioned to him that putting those servos on a y-harness would negate the entire idea because he would be only using one channel for both servos.

As for taking this all too serious, unfortunately the joking manner did not come through when I said that you should apologize to Iceman. For that, I will apologize to you. I'm doing this all in the name of education (and fun as well), so I would hate for anyone to consider my postings part of a flame war.
