Thanks for your reply. Yes, that is the hummer,
Im pretty sure the gears are fine for now, as i have tried the hummer again with another esc and motor. Ohh, very useful information about pinion gear, now i know what im looking for
I found an Ansmann sirius SE esc, 18T limit, and an ansmann clash 21t for it. I think this esc is faulty, as forward and reverese keep changing on its own lol. And almost blown my heli lipo 7.2 800mah.
Hopefully it will be 3rd time lucky.
Im getting a etronix probe 12T esc tomorrow, that should run the 21turn no probs. And also, im using a tower pro MG995 servo, Traxxas 27am rx and traxxas tq3 tx. I will let you know how it went.
Just 1 more thing, i use a NX82 dual output auto peak charger 5amp charger, and my batteries can get pretty hot. Takes about 15 minutes to charge 1800mah nimh pack. Is it ok or should i invest in a proper charger? If so, what would you recommend?
Thanks again for your helpful advices.
