If you shop around you can get a good running G-62 for less than $300.00.
You won't need a pipe and they will last for ever.
I have one in a 108" Mr. Mulligan and it is impressive.
You can do a little research and come up with the weights.
I'll bet it's not that much more. And maybe even less if you go to full EI.
By the way the G-62 is a chainsaw engine and will turn 10,000rpm.
The only replacment fo cubic inches is cubic feet.
The G-62 weighs 4lb even, with ignition and no muffler. I have one sitting on the shelf right now. It would definitely kick ***** for this airframe, but it is way too heavy.
I want this engine for a 2M pattern plane and the weight is an issue for that application. I am not competing with it, but I want to stay close to the 5kg limit to retain the flying characteristics. If I can get a 20x10 to around 6800-7000rpm and keep the weight down around 5kg, it would be perfect for me. I will get in touch with Scott at Brillelli and see if he has any newer test data on the 36GT with a pipe.
Thanks,
Mark
