Default what u think about my new 6 blade prop ( got a 5 blade ready to test)

going to try this out in 13", 14" and 15" lengths to see if it works better that the 16x10 on my gasser motor. 50cc twin, chainsaw 33cc and zenoah motor. could also run it as a 3 blade

Dude I just did that just last weekend.
I put two three bladed props on my Saito .62. I have bench tested it and all went well. The props were already balanced so I just bolted them on to engine with the prop nut. I kept the prop blades equal distance apart to help in balancing the whole thing. I plan to do a thrust test this weekend. I want to compare the difference between a three bladed prop and a six bladed prop. I am looking for grunt not speed.

Looks like it would be very hard to balance. Might want to use nylon lock nuts for safety. Overall I thinks it's killer and hopes it does what you want. A+

those where for mock up. put lock nuts on it. ran smooth as silk. smooth than the 3 blade. it weighs 251 grams total. hubs and bolts 106 . blades 24 grams each. going to drill 15" hub not enough for the 50

Great thought process. You are a pioneer in prop/hub development. I look forward to see what's next.
Thinking outside the box. I like it.

Cool airboat! Can you give some specs, or tell me where to get info, as I'm interested in building a gasser airboat for myself.
Thanks,
Bryan

You have heaps of thrust with that prop set up. She looks good on the water nice and smooth.

i will sell them. it depends on the size of the hub and the length of the blades. my 5 blade is made with 11x7 apc props. and a 5" hub making it about 15" long.
