I have a Hacker Master Spin 99 opto that is a back-up for my pattern planes. I'm assembling a TT X50e heli with the Ace TT 50/06-5H motor (630kv) and plan to use the stock 15 tooth pinion and the 135 tooth main gear. I have Thunder Power 4400mah 10s 45c batteries. Currently I can hover do some forward flight. At best, I may do some mild 3d in the future. Does anyone have experience with this ESC? Also there is a normal heli and a two governor modes. I'd like to limit my head speeds to around 2100 RPM. Any suggestions on setting up the governor?

I don't have that ESC but you can get the 'Jeti Box' to make programming easier.

I will say that your gearing is rather high especially for just general flying around. If you can switch to a 13T pinion and run on throttle curves till you've figured the governor out. The two governor modes are probably just governor high and governor low depending on the motor pole count and KV. Try an IU throttle curve like 95-92-90-92-95, with the 13T pinion that should get you around 2100. 2100 is still rather high for general flying around IMO and you could get away with going down to 1800 using a 12T pinion and you would get super long flight times! The 12T would spin upto around 2050 at 100% throttle.

60% of the time, it works every time!
