RE: Byron F16 conversion into EDF....
I converted a Byron's F-16 to EDF for a friend. I made my own adapter to bolt an HET 800-73 series motor with 590KV. System ran on 12S and flew well. I was getting about 16 lbs of thrust at 94 amps at about 24K. this data is from the Castle Link data logger. I made a rather simple carbon fiber/end grain balsa laminated motor mount that failed due to a structural failure of the glue joint between the carbon fiber mount and the nylon/plastic motor tube. I am redesigning the mount. One thing I did notice in some bench testing I did was that under full power the motor tube was rotating/twisting slightly under varying throttle applications. I thought the structural integrity of the shroud/stators/motor tube was rather weak. I sanded all of the radii where the stators met the outer shroud and where they met the motor tube. Once sanded, I put some carbon fiber mat in all of the radii and secured with expoy. This cured the structural issue and now all I need to do is to redesign the motor mount, which will be machined out of aluminum and then glued to the motor tube and secured with four machine screws around the perimiter of the motor tube/motor mount interface. To mate the 8mm motor shaft to the Byron rotor I used the Great Planes prop adapter (P/N: GPMQ4971)
