interestingly we have also just done some testing on a customers engine - purely coincidental. but i'll post the findings and video here too.

brand new GP 61cc, 35:1 Putoline MX5, 25 deg C and props as shown

23x8 Hawk wood wide blade prop - 7120 rpm
23x10 Bambula wood - 6700 rpm
24x8 GP carbon prop - 7220 rpm - thats approx 16,4kgs thrust!

I have been flying my 61 with the bambula 23x10 and its been hauling the plane around, time to swap for a 24x8 GP prop

i still think the 23x10 is good for imac and the 24x8 will be best for 3d
