Hello,

I have done some redesign work on the payload for a semi-autonomous blimp.  An Android smartphone is going to connect to the motor and shaft encoder (so I know if a drive belt slips off the motor and the propelled stops going when the motor is still going) via Bluetooth.  I have chosen this approach because the smartphone I am looking at has GPS inbuilt, as well as an accelerometer.  My question is what is the best approach in terms of where the motor(s) are mounted (I was originally thinking that the balloon will have neutral buoyancy and have an up/down motor mounted on the gondola, and have a motor on the back with a servo-controlled rudder.)



Thanks
