Flyboy,

I used to hang around on the prop powered speed models forum. I recall the reason I bought those 2 was of how you liked them in your fast planes. Like I said, the one in the Pole Star turns a smaller prop and it's dang fast. I love the power and how it normally 1-flip starts. I was just amazed at how it turned the big 14-6 and pulled the Ultra Stick 60 around. Mine are both keepers. I do hate the bolt-on muffler.

Mine were both so tight I had to heat gun the cylinder to get them to turn over. I always bench run first, so after a couple of runs, they were fine. They were "crunchy" when new. I like that. They aren't going to wear out any time soon.

I've had Diamond Dusts with Rossi .40 Pylon and Fox .46ABC and a wudened, twin engine version that was scratch built. Plus I'vehnad a couple of Mach Racer deltas, without gear, of course. One had a Magnum .52XLS with a Rossi short pipe. The other had an OS .50SX with a Jett muffler. These were pretty fast, but when I rolled over 70, I noticed my eyes and reflexes getting much worse, so I had to fly slower planes. Getting old is a *****, ain't it.
