Chopper Man...
How do you like the tower version... I'm ordering the orignal Utter Chaos from bridi and have a 40 or 46 and assume I should go with the Evolutin 46. Tower says the ARF is 5.5 .to 6 lbs and Bridi says 5.. wonder what the difference is - maybe engine size has a bit to do with it.

I'm thinking of rotating the motor 145 degrees to get the muffler down near the bottom
