For those interested I am posting machining drawings I used to convert my R60 to a prototype electric R60. The bolt pattern in the plate is for a Neu 1915H/1.5Y and the shaft adapter is made for a 6mm shaft. All materials are made of Aluminum. A note of caution: When the shaft adapter is made try to stay concentric as possible and keep run-out to a minimum.

Once I get it back together I will weight with and without batteries.
I am in the process of making battery packs and swapping out gears.

Sorry for late reply on weights. Madgadget
Heli without batteries 9.0 lbs
Heli with batteries 11.1 lbs
I have 12 A123 cells and a HV 85 ESC

I will try to go lighter with the 1915/1Y which has a higher RPM/Volt and would only require 8 A123 cells and ICE 75 ESC. This would shave off .8lbs. The only change I can think of right now would be the 1915/1Y has a 5mm shaft instead of a 6mm. I will give this a try on my other Raptor. It will put me around at the same weight or lighter than the stock gas version. Which is 10.3 lbs fully equipped.

That's a brave conversion! What's the power and flight times like on 12S A123's? I'd expect it's a sports set-up.

Complete conversion not done

"Cam" the first conversion gas to electric was a step towards a bigger conversion, but to answer your question. Yes I am running a sport set-up and getting between 7-8mins at 1/2 to 3/4 throttle. I have been adjusting pitch and rpm to gain more flight time. There is plenty of power to spare and the heli sounds terrific!

I will post pics when I finish the complete conversion. I have a buddy grinding a new shaft from stainless to step the shaft down from 12mm to 10mm. While he is doing that I have been working on the heli mechanics.
