Hi All

I have a JR voyager E and I have just upgraded to a hacker motor and speed controller. but I can't get the head speed up enough to lift off the ground. the instructions say, set it on full throttle, wait for the beeps then go to low throttle, and then its set.

I have tried everything, but I guess the head speed is less than 1000rpm, the throttle curve has no effect. I'm using
JR 3810 TX JR PCM rx,
ultimate BEC
Hacker c40 -14l (2143rpm/v)
hacker heli master 40 3P opto
10cell 3000mah

once it gets up to a certain speed increasing the throttle has no effect.
I'm not sure if its a faulty speed controller or I have the TX settings incorrect, or if there is some settings I can do on the controller.
I checked that it was set for a hacker motor as per instructions(timing and frequency)

I'm very frustrated and feel let down, as at least it flew (just about) on the standard controller and brushed motor

any help or suggestions would be great

It sound like you have it in governor mode? If you want to get more head speed you need to adjust your pitch curve on your transmitter to a higher percentage then it is now. You can also turn off the governor mode and use a regular pitch curve to get your head speed up as well. I don't have your particular ESC so I can't really tell you how to adjust it. You might also have too small of a main pinion gear? Sorry I can't be of more help. I'm sure someone will chime in and yo will get your problem solved.

Take Care,
Cheers, Patrick
