Default RE: Flaperons? Those keep your wings from getting tired, right?



Just kidding.
I have a .46 p-51 that's a little hot on the landing. I want to try using flaperons to slow the speed during landing. Anyone got any tips for these?
Here's the plane: http://www.nitroplanes.com/p51dmustang401.html
It's got a 57.5 inch WS.
I have the flaperons set to go to 40% down when I have the 'landing' mode set. I'm going to have the elevator stay where it is and adjust it accordingly after I get her up 2-3 mistakes high and switch to landing mode.
I made sure the flaperons move the same amount when the switch is flicked. Made sure the servos could still move to the full extent without binding. Anything else to check for?
How effective are flaperons on small models?
I'm going to try flaperons again tomorrow. Last time I tried it on this plane the model became wild looking. I think 1 flaperon went down while the other stayed put....

I Have used flaperons often for the same reason you wish to achieve, slow it down for landings. definitly it will require some down elev mix. I also suggest some aileron rudder mix as well. I set this up to be controlled by a switch but also by throttle position (you selec}. Then if you wish to abort landing just increase throttle, flaperons come back to normal and all is well. reason for rudder mix is ailerons become less effwctive at slow speeds. I can't tell how much down elev or rudder mix to use that you will have to experiment with.
