i have a Alfa trainer and the first thing i have done so far is put in a .68 engine(bought it brand new for $50), if you plan on keeping the same engine use a two bladed prop, and the things i have planned are;


install nylon bolts instead of using rubber bands
converting to tail dragger
taking out the dihedral in wing
change the covering to give it a better look

and if that all works out maybe i'll use a 6volt reciever battery for better servo response and turn it into a low wing plane and maybe round off some of the corners on the fuselage to get rid of that box look it has now.
