OK so I was at the LHC the other day and what do I see? I see the new 96T main and 11T pinion for the 50. Of course it jumped right into my pile of goodies. I currently have been running 11S with the 30 gears. Now I'm going to switch to the 8.73 gears and 10S to loose a little weight and regain the headspeed lost with the 30 gears. I might even go back to the Jazz55 and keep it on 10S. That way it will free up the 85HV for my E-90!If you skip me I can't play!

Some guy had a R50 converted for an AP heli by several of us guys and used one, can't remember which one and it smoked. Gave it to me to install a new 24-5. He was using a HV85 on 10S Emoli packs. I did see where the pack was rubbing on the side of the motor, may or may not have had anything to do with it burning up. Has Payton ever flown his converted Predator with the A50-16L?

Yup, Peyton has had the e-preator up a number of times. Not sure how long the motor will last for. He says it seems to be fine. He's using for AP work.

I'm about to finish up my Airwolf with the e-raptor. I'm needing to know which motor & gearing i should use with 10S to keep it running cool and not worry about the motor going bad. I currently have the Hacker A50-12S on 10S with 30 gearing. Head speed is high about 2000. Using CC85HV.

You could probably dial it down to 1800 or so, you might have to go down as far as 50 on the throttle curve to get any reaction out of the esc.
