RE: Elevator + Tail wobble
bushman - the plane looks pretty and the installation looks good. only thing is the throttle looks like it could hit the elevator servo. should cut it to ensure there's no interference. also, have you checked the CG? your rx and battery placement would depend on it. since you have a very light engine there, you may end up needing some nose weight. i'm not a big fan of the LA series of O.S. engines but if you've got it, no problem but you'll most likely be a little light in the nose.
terry, it doesn't look like there's right thrust on that engine. have a look. looks like it's pretty much dead center.
