Craig,

I haven't weighed the 3-blade, but it feels a good 1/2 pound heavier than a wooden 2-blade. Next time I have it off the plane, I'll weigh it. The only 3D stuff I've done is some TR practice. It takes a little more throttle and the throttle response isn't as quick. I'm in the middle of the IMAC season and so I haven't been doing any 3D. That will come in about a month. Not my strong suit, but hopefully will be much better later this year.

I haven't flown with std. mufflers on this engine. Jason at DA said I could expect about a 200 rpm increase with the cans. But I haven't got any first hand experience there because this enginer has been run on the cans since new. I'm getting about 6100 with the 26-12. I'll tach again this weekend to get a good number. I'll see if I can tach the 25-12 this weekend, too. We'll both be flying at the Southern Ohio IMAC Challenge.
