I mentioned two different Thunder Tiger resellers earlier in this thread. Ace Hobby is the North American distributor for Thunder Tiger engines and Omni Models and Tower Hobbies sells most of their engine line while eHobbies.com, thundertiger4u.com, and infinitehobbies.com are all major online resellers for Ace/Thunder Tiger products.

There is an entire class of pylon racing built around the Thunder Tiger Pro .40 ball-bearing 2-stroke, and Thunder Tiger engines are usually mentioned at the top of a short list of some of the finest 2-stroke engines sold today.

Thunder Tiger 4-stroke engines have a solid reputation for reliability, but have fallen out of favor in recent years because they're heavier than most other brands and up until recently they've used an air-bleed carburator instead of twin needles. This too is changing.

The new Thunder Tiger F-75s 4-stroke is a ringed-piston design sporting a new twin-needle carburator and its weight is almost identical to the Saito .72. The F-54s and F-91s are currently being updated as well, with specifications yet to be disclosed.

The biggest difference between the TT F-75s and the Saito 72? The Thunder Tiger sells for $50 less.
