Need some help!
 

Okay I am putting together my first ARF nitro model which is a .40 tower trainer, I just hinged my aileron's tonight and I'm somewhat concerned I may have to much gap between the control surface. I know to much can cause the ailerons to flutter, I measured the gap and it seems to be about a sixteenth of an inch, to an eighth of an inch gap, maybe less it was kinda hard to tell. Anyways I was worried becasue now it cant be undone! So let me know what you think.

For your trainer I would not worry about that amount of gap. It will fly fine.

This forum is for the company Nitro Models and their planes. For the best help with trainers in general I might sudjest you post in the beginners forum in the future. Not that I mind helping you here though:D You will definately get faster responses in the beginners forum as it is always very active with people that only want to help you. Best of luck with your new plane! You do have an instructor... right?

Yes I live in The Dayton area in Ohio so we have a AMA flying field, this is not my first rc model I have flown electrics for about a year, but this is my first nitro model so I was just wondering about the gap because I built a GWS formosa and had the same problem and it didnt come out so good! Thanks for your help I really appreciate it!

You typically want about a pin's width or just a bit more of space showing.

But as he said it's not going to be a big problem on a trainer.

Most trainers have relatively small control surfaces and overspeeding the trainer is never a problem.

If anything having some gap makes the CA joints a bit more flexible and less likely to bind or hold up the servos.
