Does anyone have experience with the Thunder Tiger .36 pro engine? It is a ball bearing engine. How does it compare with a .40 size bushing engine such as an OS .40FP or .40LA given a certain size prop? Would the lighter weight and the fact that it has ball bearings make up for the slightly smaller displacement?

Excellent engine for the money. TT's have one of the best carb.'s out there IMO. Very strong engine for it displacement and weight. Turns an APC 10 x 6 @ 12500 on 15%.

I would most definetly go with the TTpro 36 over an LA 40. I am really sold on the TT pro line of engines they are fantastic engines. The pro36 is a little pricey, although you can get the 46 for about 10 bucks more and the pro 40 is actually cheaper. But the 46 and the 40 are a bit heavier.

The weight difference between the 40LA and the pro 36 is very little.

What plane is it for? Overall I think a good 46 engine is a little more versatile and most planes that call for a 36 do fine with a 40 or 46.

The plane is a scratch built 3D airplane made of half inch blue insulation foam covered with Econokote. Basically it's a scaled up flat foamie, but powered with a glow engine instead of electric. It has 600 sq. in. wing area and is currently powered with an OS .40LA with an APC 11x3 and total weight is 3 pounds. I'm looking for more power without extra weight. This is why I'm considering the TT .36 pro.

Oranges and Apples.

The TT PRO36 will eat an LA or FP 40 for breakfast and still not be hungry at lunch! Overall, the PRO36 is the more flexible engine of those two. If they're the same price, it's almost a no brainer.

Like it's bigger brother the PRO46, the TT PRO36 is a tremendous engine in class as was the O.S. 40FP in its and is the LA if in reality to a less popular extent. But they are completely different class engines. Buy the TT PRO36 if what you want is gobs of power or speed in class. OTOH, if you want a 2 stroke which behaves like it thinks it's a 4 stroke, 'cept with less outright torque, then go with the FP. Ideal use for an FP/LA would for instance be in a typical trainer, SIG Four Star 40 or SIG Lazer Fun Fly where you didn't need or want to set climb or speed records. Very reliable, good throttling with adequate power and long lasting.

OTOH, the TT PRO36 would be in its element blatting about in something like a Sportsman Aviation Sonic 500, or [link=http://theworldmodels.com/para/products/airplanedetails.php?airplaneid=7]World Models Extra Sports 30[/link].

I second that... if you never experanced going from OS to TT you're in for a treat. All the tuning ease but more high end. The break in is strange fuel and go never touched the idle it just purred. Rich

I just ordered the Thunder Tiger .36 Pro for my 3D funfly. What kind of rpm can I expect from an APC 11x3 prop once it's broken in? Also, Tower suggests that it be broken in with a 10x6 prop, which I don't have. Would a Zinger 10x5 wood prop or APC 11x3 prop be OK for break in? I have both of these already.

10x5 Zinger will be fine for running in.

Dunno' re rpm on the 11 x 3. Will just have to tach and see. Plenty sufficient on that pitch though. RPM wouldn't be the performance constraint running that diam x pitch in any case. Adequate thrust in conjunction with rapid acceleration/deceleration of both engine and prop thrust / drag is what you're after, which the ideal prop/engine/airframe marriage for the fun fly task should offer. Just guessing, but I suspect even with an 11" blade, a 3" pitch may possibly even be a little shallow even for 3D on the .36. If the weight and model size is right, with the correct prop selected you shouldn't require above approx ¾ thtottle even in hover.

How would this engine do in a speed plane like a Shrike with a high pitch prop?

'perfec'...

I run the 11x3 APC on my OS 32. It's on an Uproar and that prop is excellent. The OS 32 and TT 36 should like it equally well. People think it's a .46 on there usually with unlimited vertical.

The .36 is actually about 8oz lighter than the ST .40 I believe. I'm scratch building a quickie racer just for sport flying and I plan on putting a 36 pro in it just to save the weight. (These quickies seem to always come out nose heavy anyways.)

Love TT Pro carbs, I use them for just about everything.

The TT36 has always been a good engine
