I'm looking at replacing my Super Tiger 40 with one of two engines. The OS 46 AX or the Thunder Tiger Pro 46. I'm looking for reliability, good power, quick tuning, and a solid engine well assembled. These are all things I have fount at-fault with the Super Tiger, I guess "getting what you pay for" is true after all. Though I'm sure there are people out there who have gotten a good Super Tiger engine, I was just one of the unlucky ones.
I have owned many OS and Thunder Tiger engines in the past and I have never gotten a bad one yet. Out of the two engines above which would you pick?
Why do you want to replace your ST GS-40? They are good engines and should not be causing you a problem if all is normal with your sample.
I doubt if you will see much difference in power between the GS-40 and the OS .46AX. A little, perhaps, but not $60 worth. At least, not to me.
ST engines do have a good warranty. If you are happy with the power the GS-40 is producing, which is considerable, I would give the folks at Hobby Services a chance at fixing it, even if you decide to buy a new engine anyway.
I like both the OS.46AX and the TT.46Pro. Both are good engines.
Is the OS worth the extra money? It is to me.
If you are looking for something less pricey, don't forget the Magnum, SK and the K&B .61, which produces great power and is about the same size as the schnuerle ported .40 to .52 sized engines without weighing much. There's no replacement for displacement. <G>
