Thanks, Jon. I have another plane I need to finish, then will tackle the T-28. The engine (Tower 75, 12x6APC) has plenty of power! It was climbing out at 60 degrees until I could dial in some down, and I was cruising at 1/3 throttle. I have the stock nose gear, bent in a dogleg, with 2&1/4" wheel and the stock 2&3/4 mains. The wheels already look much larger than scale, so I'd rather not go larger. Bending shorter mains should not be that hard. Time will tell.

Sure looks cool in the air! I can see why some have installed retracts. Now, if I could find a reasonably priced set of electric retracts...
