RE: Nitro models pusher Bobcat?
You shouldn't have a problem.
Take the stearing linkage setup slowly.
After I made my cutouts I found a nice fuselage linkage pass thru system ( from Hobby Lobby ) that would make my Pull-Pull install soooo much easier and neater.
Basically it's a small vertical bell crank used to bring controls outside the fuse. You need two, one for each side.
Some people have put the stearing servo in such a way that the control horn is outside the fuse.
There are also a few mechanical retracts that have a "slider" for a single rod/line nose stearing, that may work as well.
