Default os25fx or TT pro36?

I am wondering where I ger the best power to weight performance. I dont trust the numbers posted in their web sites.

Also I am surprised to see that they are the same price. Any explination?

My buddy has a TT .36 on a Wonder and it absolutely screams!!! Not sure of exact RPM's, but I know it was alot more powerful than the Mag .28 I was using. Made me wish I'd spent the extra $15 bucks.

Default Power:Weight

CRASH,

I was wondering the same thing a while back and went with the TT Pro36. Weight of 8.8 oz for the OS 25FX does not include muffler. The TT has about 1.1 oz of fat if I recall, 11.4 oz/323 grams with muffler.
This works out to be about 10% more weight and 44% more displacement over the OS25. The Pro 36 swings an APC 10x6 at 12500 and apparently has more jam then the 32SX.
I'm really happy with the performance and quality of mine. Excellent power plant!

Happy Fly'n....

This may not help but I have the OS 32sx and it screams. I just tested the RPM's and I was getting nearly 16,000 on a 8.5"x6 prop.

Default Irvine 39

Ernie,

I've heard nothing but good about the Irvine 39, but isn't it getting up there in weight?

I think the idea here is most, "Bang for the Buck" weight wise in a 25 size?

I done a little poke'n around at the web site's.

Irvine 25 - 12.1 oz/ w muffler. Irvine 39 - 13.6 oz/ w muffler

OS 25 FX - 8.8 oz/ wo muffler OS 32 SX - 9.5 oz/ wo muffler

Gotta figure the muffler is at least 2 oz. All are good power plants, but for wieght per cu.in the TT Pro 36 looks like the best bet?

Happy Fly'n....

I own 2 TT PRO .36's. Both are bolted to a Twinstar. I wish every engine had the power and reliability of the TT Pro 36. No problems, incredible power, easy to tune, and easy starts makes it a winner in my book.

Default Twin 36's

Dave,

You should consider mounting your pair of 36's in that NEW Great Planes Profile P-38. That would be real fun!

Happy fly'n....
