OK, I just added another servo to my Nexstar and set it up for flaperons. The 6exas Futaba makes this a snap. What I don't know is how much throw the full aileron flaps need. The manual states 1/2" if you go with 6 servos and cut the ailerons to have seperate flaps ( at 10" long ), but no throw info with the flaperon setup. Has anyone done this and what do you suggest. I have it set up with 3/8" throw, but is this too much or not enough? Thanks

I am of the opinion that flaperons are not a good idea period. They do nothing but increase the chance for a tip stall.
If you really want to do something to lower the stall speed, or be able to make a high angle aproach then do the mod to add flaps, as they show in the manual. I just did this mod to my nextstar, just to play around with using flaps on an RC plane. The weather has not been good enough to try it out yet so I can not tell you how it works out.

As far as throw I think 30 deg. is what is used for flaps, as far a flaperons I have no idea I would never use them. Good luck, have fun with it.

I have mine set up for flaperons. I have used them several times and my experience with them on all occasions have been other than good. It seems to throw the balance of the plane off somehow in my opinion. Yes the plane will slow down, you are adding drag. You will lose major aileron control and reactivity though, least I have. In my experience the plane tends to want to become sluggish and drops a wing. Good luck if you add flaperons to it. Flaperons may be good for some aircraft but I the you might be better off with regular flap setup for the nexstar.

I would not add flaperons - tip stall is going to happen at slow speeds/landing, and that means low attitude without any chance to recover. I have a Nexstar with the flap option. Makes a good slow flying trainer way up high, but landings are harder because the plane just floats and floats. It climbs even at 1/4 throttle with stock OS 46 FX motor, so be prepared to trim her for nose down attitude with you use the flap option. I followed the directions in the manual and the only problem I see is trying to cover the section of aileron/flap are you cut, makes it hard to do with it already installed. The flaps also make the plane look neat.

Bigwes....I can second that. I had my "maiden flight" last week and boy,o, boy...it sure seems like you loose a lot of aeleron control with the flaperons. I'm going to remove em tomorrow and re-trim the Nex. Hope she will gain the control I am use to with my other trainer.

It sounds like I need to buy anothe servo and do flaps. I would assume the flaps will make the plane land the same way it did with the air brakes that came with it, assuming I had the flaps down! So if I do the flap option, the ailerons are now shorter. Do I need to increase the aileron throw to compensate for having less surface area to work with?

I would say that if would be a good idea to give the aileron a bit more throw, but don't go nuts.
As far as the landing, I have yet to try mine so I cannot say anything about that.
