Is the Thunder Tiger.39 that much stronger than the OS.
has anyone tried the Irvine .39 or the Webra heli engine?
I'm wondering if there is a stronger engine in the .30 size class.

i started with the TT39, it was OK once i got the carb modified, but it really is not a great engine IMO. I haven't flown the OS 32, but the power and quality of the OS 50 SHX is outstanding, so i would be inclined to recomend the OS or the Irvine.

I know a guy that has a TT39 and he said it was a great motor, it has more power then the OS32. I have the OS32 and I can tell you one thing, it is a very reliable motor. I have never had a problem with mine. In my opinion it should have a little more power. If you are a beginner, the OS32 would be a good motor for you (very dependable). If I was going to buy a new motor for my 30, I would go with the TT39 (but that's just me). I have read some good things about it, plus I would like to have a little more power.

someone must be flying a webra .35 heli engine.........

I'm not 100% sure if they make a 30 size, but i'm pretty sure they do, Western UK make some pretty awesome heli engines, we've just finished running in and testing a 50 size version and the amount of power FAR exceeds that of the OS and TT

The OS 32 is nowhere near the TT39 in terms of power. The TT is a bit finickier but once it's settled in I wouldn't trade it for an OS for anything. I have ran both in my Hawk Sport and my Caliber 30. The TT wins hands down. Can't comment on Webra or Irvine as I have never ran one in a heli.

I had a raptor with the TT and one with the OS. They were very comperable. The TT was just as reliable, had virtually the same power. There was not a noticeable difference. I run TT in my 60 and my boss runs OS. Same situation there. In flight, you can't really tell the diff. They run identical. I like the TT engines. Wouldn't hesitate to buy them.

Webra engines are great engines, but a real bugger to break in. Once broken in, they are one of the best engines you can fly.

I have used irvine off and on for 20 years. They have always been a cheaper engine, but run good, run strong and are reliable. My friend has a brand new one and it is very impressive. I may try a couple of them on my twin that I am building. They are great running engines. We will see how his lasts. The old ones got tired faster than some, but we ran them with high nitro.
