Thanks DGrant....I appreciate the advice. I'm learning a little everyday. I went ahead and bought the D645's and will start the project soon. I'm enjoying this hobby so much I have gone from foam trainers to "stik" planes and now starting to look at larger planes and warbirds.
I enjoy building kits and really want to build them right with the proper engines, servos, etc. So learning everything I can is helpful. These forums have really been helpful to me.
