Stinger kit with 600mm fiberglass arms. This is a great kit, cheap, flexible, light, and strong. Lots of accessory parts matched to the 10mm arms.
Hacker Style Brushless Outrunner 20-22L, 924 kV. Recommended by Davvid "dadde87" Windestål, and have been good performers both on this unit and the Arcticopter I.
Props: 10x4.5. MontoRC props have been really good so far and need minimal balancing. They're pretty stiff as well.
Battery: I've had good luck with Zippy 3S/2200/40Cs. flying sedately, 25Cs weren't too bad.
Weight: 714g without battery, 915g with.
Proton 18's from Exceed Rc. These are as far as I can tell the same pieces as the ATMEL Turnigy Plushes. I got them with the idea of reflashing them, but haven't yet done so. The power setup above maxes out at just under 10 amps on the bench, so for a while I was using a set of 10 amp ESCs, using the logic that full throttle for more than a couple of seconds would send the unit to points unknown. I felt better when I saw Warthox using 10 amp ESCs!
Look here to see how I cover the electronics.
