Newcomer to electric power! I have a cirrus 2 meter glider that I am converting to electric. I have mounted an Ultrafly Frio 10 motor with Apollo 25 speed controller and 3 cell 2200 lipo battery. Can anyone recommend folding prop size and type of shaft adapter to use. I think the battery is probably on the large size. I have access to a 3 cell 1300 and a 2 cell 2100. Will this motor run very well on the 2 cell battery? Open to all recommendations. Thanks
