actually i put the stock reciever back in and dida range test. This thing only has about 30 feet of range before the motor shuts down and i get servo jitter. Any ideas on how to expand my range or use that spectrum set up. Iam also looking at upgrading the motor. If Iupgrade to a better motor. esc and lipo setup, will Ibe able to find the small gear that fits the main prop drive shaft for the new motor.
