I am currently building a Phoenix Extra 300S ARF. I have had 4 or 5 planes and always either bought them used and built or had a flying buddy help me build them. This will be the first one I did by myself. The engine mount comes preinstalled on the plane does that mean the right and down thrust is already "built in" or do I have to do it myself. If so how do you do it without all the special tools they make for it. It calls for 1 degree down and 5 degrees right the engine mounts at 90 degrees. Also the control surfaces come preinstalled they look like they have plenty of glue and are very strong should I try and add more glue to reinforce or should they be ok. Thanks for any help I would really like to get to where I can build a plane by myself without worries.
