I'm assuming that the SK 50 would also be happy with an 11x6 (that's what the Kangke site recommends). I might want to try one in something like a Kwik Fli one day which has trike gear. A 12" is just to big for grass fields.

As you probably know, diameter is only one way to increase the load. Stick with an eleven inch diameter prop and crank in some pitch to compensate. Besides, if Kangke recommends an 11x6, you could also use a 10x7 or 8 to apply the same load to the engine and make it happy, while gaining prop clearance. Can't wait to get my SK .50 and .90 mounted up and running.
The wife's new business has taken off and has consumed my "shop". That's why the delay in getting things going again around here. I miss the space, but money is nice too. <G>
If things keep going as they are, perhaps we will be moving to a larger home with a separate shop for my uses. I can handle it.
