yo man, I really like the 3blade prop on there... how do you cut out that spinner so nicely and also the cowl? do you just buy a specific spinner? most spinners with the kit are precut for 2bladed... I want to do what you have done... ok as far as tuning goes, I do the same as you on the HSN... always with a new engine and maiden flight I point nose up and ensure I don't lose any power... the low end I just use to lean until I get no more bogging or hesitation from low revs to high revs... I always start with HSN as this is the fuel flow and it effects the LSN as well... I will give it a shot the way you do it... thanks for help... help me out on 3bladed part please... it looks so much more like the real thing, I love it!
