Way on back in the day, I was instructing some guys on PMCS for the Ma Duece......One guy decided to get ahead of me and cracked the receiver halves open before closing the bolt...lost the tip of his thumb....
I'm used to working with 9 inch props.....I decided to go with an 11 inch on this one....that extra inch radius is what got me. The prop seems to have not taken any damage though and the 11x7.5 was putting out some serious thrust even at half throttle
I'm going to use the aircraft pontoons because they're designed for grass or water....keep the lower spacers and struts and build a frame just above that....motor mounted in a puller position towards the rear....not really worth it to go to a pusher position.....it'd take a $70 exhaust to redirect the exhaust properly and clear the prop and since I'm ground up building the rig, I can accommodate the orientation.
