I want to convert my Bell 47 to electric and since this is my first electric helicopter I wanted to get an idea what Helicopter World would recommened. Tech support recommend using a Scorpion HK 4020 890Kv motor and 100 Amp ESC on 6 cells. I'm using the stock gear and clutch setup that came with the helicopter and a 19 tooth pinion gear that comes with the Century electric conversion kit. I want to keep the head speed at around 1600 to 1700 rpm. Helicopter World's tech said that this was the combo to use. What do you guys think. Thanks Ken

I agree with Boyd, Bellbloke has a great thread on this heli kit. I have an 800kv Kontronic motor in my R22 with the same mechs and set up, just different fuse. I'm shooting for a lower HS on 6S. I think Century was recommending a 1600 or lower rpm HS on these mechs in a scaler. At least that's what they had for the R22 kit, as it has a very tall mainshaft. This heli should fly butter smooth on lower HS, will get great flight times and sound/look so much more scale. Here's a link to the build.

All helis and planes have an expiration date stamped on them...you only find it after you crash!!
