Hi Dave

Yes, you have to drill a hole in the wing root to clear the air line and servo connections. I prefer floating connections to hard conncetions, ie, glued plugs and fuel lines.

I installed wing tip lights by routing the cable in the main spar. you will have acess, no problem.

Try to move the aileron manualy up and down arround 50 times to see if it gets easier. it usualy does. I am using the big bore cilinders from SM with sucess.

Also made some mods in the fuel tank to install it near the CG. Can post pics later on
