I recently put together a little 250 frame from some spare parts. Arms are from those Transmitter monitor mounts and the main frame is two frame plates from a 1/24 rc car that I picked up at the lhs for 80% off in the bargain tub. Motors are (I think 3rd shift) T-Motor MT1306's with 5030 props running on 2S. It's not super powerful but manages to get along pretty well even with a 2700mah battery and an AUW of 360g (212g w/out battery). It's got a sparky tucked in the middle and flies great.
