Hello Mayhem owners, guess what I found under the tree ? Yessss, a SIG Mayhem ! They just started to sell them here in Germany, and when I ordered the delivery was postponed till just before Christmas.

I read through the whole thread throughout the last weeks and am excited to get the bird built and ready to fly. I'm just breaking in my 13years old YS120SF which was still new in the box. I bought it on a business trip to Shrewsbury/Mass. in those days. We were flying Gremlins at a field called CMRCM.

Maybe I over read it but I'm still looking for the best prop size for this engine, 18x6 or 16x8 or 18x5, 18x4 ? My experience with this engine is very low, just 30 minutes break in. Any hint or link is very appreciated.
