I've donejust about everything I can do to mine except painting, mods as follows:
Eflite power 25
Castle Creations Phoenix 80 Amp ESC
Castle Creations BEC
HS65MG Aileron Servos
Flaps (Hitec HS85BB Servos)
Thunder Power Propower 2250 mAh 30C 4S Battery
Reinforced wing with carbon fiber rod
Scratch built motor mount.
11x8 APCe prop
Canopy mod for camera
DSR-30 Retracts
Working gear does.. nose gear door was tricky!
Ironically my Corsair is much faster with a Power 32 as I can spin a 13 inch prop but it has pretty has identical setup other than prop, motor and of course it is a tail dragger.The T28 I don't like to swing anything bigger than an 11 inch prop due to lack ofclearance.The 25 can handle 45 amp burst so works just nicely with 11x8 APCe prop to push a bit better than 650 Watts at about 47 amps. Plane flying weight with 4Sis now 3 lbs.
