Yeah, I think that’s the ver 1.3 one. Those don’t work on gas helicopters with low voltage 2S system at all. One workaround is to go to 4S and use a Castle 20A BEC pro to power the servo rail. But can’t find any generators for 4S and I HATE messing with batteries. I got electric helicopters and a big TriCopter - never fly 'em because of batteries. I did the big electric experiment with helicopters a couple years ago and gave up on that. The weight you have to carry in batteries to get it to fly for 30 minutes can fly a gasser for 3 hours.
Electric: fly it for 30 minutes, change battery to fly it another 30 minutes spend 6 hours messing with batteries to get another 30 minutes. Investment in batteries - $1,000+
Gas: fly it for 3 hours, spend 5 minutes refueling it, fly it another three hours. Total investment in gas $2.64.
