Hello, I'm sort of new to the RC Helicopters,

I recently acquired a pair of Esky Co-comanche helicopters on 72mhz. I also own a new Esky Dolphin

Both Co-comanches have some metal upgrade parts, neither can fly at this time due to an apparent lack of power, they both spin up but dont even come close to the power I get from my new Esky Dolphin.
the Co-comanches do not have any vibration and the blades seem to track correctly.

I have eleminated the batteries as I have flown the dolphin with the batteries that came with the comanches.

I have also installed new battery in the comanche with same results...

What else could be the cause..both have had stock rotor blades installed in case that was the cause..no change.

I did get in one flight with one of the comanches but cant seem to get enough power to lift ...can you help?

Regards,

there is one thing you can do. Get the motor from the dolphine and test it out and see if you are getting the same result. If after you changed the motor into co Comanche and it still doesn't lift then we can conclude that the 4 in 1 controller is having some problems. Otherwise it's the motor.

Let me know.
