OK, this afternoon had some time to get the engine running. I did not have to touch the Perry pump, so that was easy enough.
I could also finalise the mounting of the engine cover. I also used a Tru-turn spinner (another extra 40 grams, but what the heck!).
So, here it is!
Total weight: 4190 grams. Center of Gravity at 16 cms behind the leading edge. That is one cm more then recommended by Protech, but I will fly it anyway as it is. Hopefully next weekend, since after that I will be travelling for two weeks [
