Oh contrair Luke... if you dont it will be a discredit to the builder !! Lol !!!

The boys comments about props.... I rest my case we agree.....
12x6 is a safer prop though if you are not used to 3D and using the throttle effectively cos at least you get a bit more go go at lower rpm.


PS
W36.... I really like this engine. I have found 10x5 my favoured prop in th epast on OS 32 and Mag 36 et cetc in the cougar for example. Anything bigger and you get lag and cant get out in a hurry. 11x4 was even noticeably to load up too much in some situs.
On the W36 it was just too revvy. 11x4 was great.. and no lag. tried 12x4 (sport prop not ffly) it did well and hovered like a heli. hit the gas though and it gently climbs away... not like the 11x4 on which it scampers away.
