I am going to get a .28 sport also because I like to mod my own engines. Rex do you just open the ports up a little and polish the crank? I open up the fangs alittle + the ports but leave the EXHAUST port alone. Was thinking of trying some crank work, I have a few old ofna force .28's around here that I ported and they fly for a cheap engine.What kind of a apoxy do you use for the crank to fill in the ramp.

I only turn left !!!
