Just picked up my first kit today. It's the Sig 4 star 60 which it seems is one of the best for a first-timer like me. I have a Sig LT40 arf that I flew the glue off of and a few others. I'd like to put a 4 stroke on it and the plans say I should have an engine before building the fuse. My questions are:
1) Are there any modifcations or areas that need more strength
2) What size 4 stroke engine would let this plane be a sunday flier
3) Can ca glue be used all on the wing sections or would you use tite-bond
