I've got a himax 2025-4200, CC25 and 3S TP's in mine. With APC 9X6 slowfly prop, it performs very well.

The numbers on my set-up are: 10amps, 26 oz thrust, 44mph prop speed, and 12 minutes fly time.

I did firm up all the control surfaces with CF rod and clipped the wing tips. With the increased speed, the ailrons really are effective. While still more of a trainer than an aerobatic plane, it has good vertical, does big loops (inside and outside) and fast rolls. I orginally planned on taking the components out of the EStarter to use in another plane, but I like flying this one so much that I can't bring myself to take it apart. If I were to build another EStarter, I would cut the wings and remove the dihyderal.
