maximum propellor diameter for a 4mm diameter flexi
« on: August 13, 2015, 02:34:26 pm »

Has anyone an opinion as to what would be the maximum propellor diameter for a 4mm diameter flexishaft?
A friend is running a 35mm prop on an almost straight 4mm flexi surface drive setup and it looks like the "spring" is under duress after two 5 minute runs. The motor is a brushless BTW and the battery is a 3S LiPo
