Guys,
I have a Wild-RC T-IFO that is just impossible to fly.
It won't turn or climb/descend very well either.
It was originally stock, Elevator & Rudder. I now have resorted to setting it up with fixed rudder, no dihedral and elevons.
The thing will just not respond to control inputs in either configuration.
I get a small nose up or nose down response, absolutely NIL left bank and very poor, if any right bank.
It glides well, straight and true from a hand launched glide or under power and the CG seems to be spot on.
Admittedly, I would like more throw/travel from the servos but just how much surface deflection does this thing need to be controllable? I have about 3/4" each way/up and down on the elevator
and about 2" each side of centre on rudder (when in that configuration).
That amount of surface deflection would have most aircraft doing barrel roles and loops but my T-IFO just keeps ploughing straight ahead, (usually for the first tree or other obstacle)!
Seeing others IFO's in all the configurations, T-IFO, Mini IFO etc they seem to be highly manouverable and if anything erratic.
What the hell could be wrong with my T-IFO ???
Prop is on the right way, connector rods are all non slip and tested I can see no reason why this bloody thing wont respond to control inputs.
Someone, Please help!

Thanks guys,
The airplane sequence used in the A Team was a stuntman double with a buddybox!
I am using cheap no name mini servos but they seem to have normal throw and torque?
The pushrods are the stock carbon rods as per plans
CG seems right on the mark and she glides straight and true. Just that I have absolutely no control over the thing. I get just enough up elevator control to flare from a hand launched glide, a small amount of down elevator but zero left bank and a teeny amount of right bank.
Maybe it's the cheap servos letting me down?
At my wits end with this! : (
Thanks

Try more throw and/or move the CG back a bit at a time till it does what YOU want, not what IT wants to do.
Sometimes you have to show them who's boss.

Thanks guys
How can I get more throw? I have a Hitec Flash 5 and have the end point adjustments cranked all the way up to 125%
If I shortened the carbon control rods, would that help?
Cheers,
Paul.

Paul:
A longer arm on the servo would do it or,I don't know what you have for a horn on the elevon, but if you can get the pushrod closer to the surface by another hole or drill another hole in the horn would do the trick.
