I have see a couple videos on flitetest about making mini planes out of like Champ parts and such but...... where can you buy the power pack setups to make your own from scratch? I imagine if you can get small enough power packs you could say make a piper cub out of tag board and foam formers and such. but finding the small power back or bricks as they are call are really hard to find. I would hate to..... let me rephrase this... I hated paying 100$ for the Champ in the first place then turn around and take it apart just to get the motor and brick out of it to make another small plane. also would like to make 4 channel with duel ailerons. still just a single servo that work both ailerons but the brick you just get elevator and rudder, I think it can be mixed for a flying wing, I think. its hard to look though these postings of over 2,000 post to add to or get what you at looking for. if anyone know of a post that covers this please point me in the right direction. thanks.
