What four stroke nitro engine is this?

[Lugga]

Can anyone identify the brand of this four stroke 0.91 nitro engine?

@Lugga,

I'm not all that familiar with 4 stoke nitro engines, but I can tell you that the manufacture is Thunder Tiger.

Can you look and see if there is any other writing or markings on the engine to better determine exactly what model?

Thanks WoodiE. It appears to be a Thunder Tiger F-91S. Never owned a Thunder Tiger before and unfortunately haven't heard rave reviews about Thunder Tiger engines. Thanks again. I appreciate your help.

It's definitely Thunder Tiger but the 4 strokes are for airplanes, not RC cars. I've had a few of their 4 strokes on planes and they are great engines.

By the looks of the photo it IS in an airplane... not a car.

Ah...you're absolutely right. I didn't notice that. I was just looking at the engine and the logo.

They aren't known for a ton of power, but they are pretty reliable/durable. At least their truck engines.
