Brillelli 36 - I had looked at it but concluded that it would be a bit light on power. I was just running some prop/power calcs and if I can get 6800rpm from a 20x10 I would get around 20lbs static thrust, which should be lots for me. I'm not sure that it will do that, however. Last time I talked to Scott he had no pipe data on the 36. Maybe that has changed since, I will have to see if he has more info now.
G-38 - I was under the impression that they were a bit heavy and underpowered. Do they respond well to a pipe?
Thanks,
Mark
Mine spins a 18x10 MA Schimatar at 8700. Never tried it on a pipe. It's sitting in my DR1 right now. I had it for sale a while back. It has an aftermarket cup mount, throttle linkage, and muffler. If I had an engine stand, I would pull it off, fab up a header real quick and throw a pipe on it. I have some laying around. I bet you could get that 6800 on the 20x10. My OS 1.60FX used to spin a Zinger 20x6 at about 7700. The 38 and 1.60 spin the 18x10 about the same, so I'm guessing it would be close. I don't think I have any 20" props laying around. I look later and if I do, I'll slap it on and see what it does.
