any of the Tower trainers mentioned will work well. so will the Eagle II.there is generally NOTHING wrong with the plain bushed engines, or loop scavenged(the few that are left)porting. we flew for years that way. these are beginner motors and as such while they have less power they are easier to adjust & quite rugged in crashes, and much easier/cheaper to repair.you can always break in ball bearing/schnerle mills on your trainer for the #2 plane.
