Our radio control club took up flying a blimp for the local college basketball team last year. While we were able to fly adequately, we know that "there must be a better way". The blimp was purchased by a local restaurant and when they couldn't fly it they contacted us. We're all gas airplane pilots and know very little about esc's and such. The port and starboard thrusters on our blimp rotate about a 180 degrees from full forward to full back (we can add about 10 degrees to that in each direction using the trim control on the transmitter). To come down we have to aim the thruster straight up and reverse the motor. This sorta works but because the prop is not as efficient running backwards, sometimes coming down takes longer than we'd like. My question is: Is there typically an adjustment on the esc to allow more throw in each direction? Do we have the thrusters set correctly?

Any help would be greatly appreciated,
Tim
