There have been a lot of good things said about the Thunder Tiger Pro36 since its release but very little written about it in the way of reviews. This should be a good engine to compare to the Webra 32 GT engine since both are affordable ball bearing, sport engines weighing less than 9 ounces.

The Thunder Tiger Pro36 is a very pretty engine. The case is pressure die cast. The perimeter of the cylinder is machined to a semi-square configuration. The head is held in place with 6 - bolts. The carburetor looks big compared to the small case and has a nice, short needle valve. The muffler appears to be a copy of the OS 40-FP muffler. It has a 1/4" prop shaft which is too long for a standard OS spinner so this was trimmed to length with a Dremel tool. This is a neat, trim package with a finished weight of 9 ounces.

The case of the Webra is a clean, well finished investment casting. It is also a pretty, lean looking engine. The head and carburetor are machined from bar stock and hand finished. The head is held with 4 bolts. The engine with its slim muffler is loud. The prop shaft of this engine was also trimmed so the finished weight came in at 8.8 ounces.

Both engines received very high marks since they are practically flawless.

The figures for objective scoring are based on personal impression only based on the outcome of comparing the engines.

The winner is...Webra...but not by much. Objectively, the winner should be Thunder Tiger simply because it held its own with a little thoroughbred which costs $30 more. The Webra is well worth $105 but the TT is an exceptional value at $75. Perhaps the TT is the best value of any quality engine in its class, consisting of all lightweight .35 size ball bearing engines.

Both of these engines are highly recommended as a first engine or the very best engine for that favorite, light, .40 size sport plane. These engines actually pull a 9 x 6 prop better than all but the most powerful .46 engines and weigh much less. A lightly built Cloud Dancer, for example, should sizzle with either of these engines, yet handle superbly due to the weight savings over heavier .40 -.46 engines.

The Thunder Tiger Pro36 can be considered "a poor mans Webra" and the Webra is simply a killer engine. A lot of cheap thrills can come from 5 pound or under sport plane or trainer powered by either of these engines. These little engines are about the same weight as most .25 engines so will they be right at home even on a .25 size plane and give ballistic performance!
