Help out a *Brain Dead* guy here......

I understand there are two versions of the Thunder Tiger 36, no?
Which one is the *desireable* one for stunt, and how will I identify it?
TIA
Bill

Two versions :

1) airplane

2) helicopter

Bill:

Are you thinking of Randy's Aero Tiger variant? If so, Randy (as I understand) installs an aftermarket AAC piston/liner assembly that reduces weight while optimizing timing. Again, these are non-Thunder Tiger parts - so the two types would be a standard Thunder Tiger and an Aero Tiger. Len also reworks the TT 36, but uses the standard P/L assembly.

nah he is talking about the fact that there seems to be a "Squarish" looking one like the way a magnum 36 looks then there appears to be a rounder one like a webra32 or fox 35 or whatever... wondering if there is a difference, if there is really a rounder or squarer one etc...

i am the one that noticed this but it could be that i just dont know what the heck i am talking about! hahahahahahaha

Aaron:

If Thunder Tiger followed the same process that Magnum did (are they made in the same factory??), then the "squarish" style is a later production model than the more rounded cylinder head.

Thunder Tiger and Magnum were made in the same factory, but no more. Thunder tiger is Taiwan and Magnum is now mainland China with ASP. But, yes, the "in" thing is to go square fins, even though we, in the cl fraternity don't need them and now must pay the extra weight penalty that they enact.

Lets go through this one more time.
Thunder Tigre was sold for years through Hobby shack under the Magnum name. My understanding is that at the time World Engines had a problem with Thunder Tigre using the name Tigre in it's name thus the renamed Thunder Tigre/Magnum.Thunder Tigre is and always has been made in Taiwan
At any rate there must have been a parting of the way between Hobby Shack and Ai Ling at Thunder Tigre with T.T marketing it's motors in the US under it's correct name that it has sold it's products worldwide naimly Thunder Tigre.
Hobby Shack retained it's rights to the name of Magnum and has it's motors made in China at the same place that ASP and a few other brands are made.
That is why you see the confusion still over these brands,
Incidentally the reason that the thunder Tigres look and feel so much as OS is that they got the designer of the OS FSR/FS/FP motors to work for them after he left OS. Since he already had made some very good motors there was no reason to re invent the wheel.

Hi Arron and Bill:

I fly the TT36 PRO from Leonard. The the big overhanging square head is the Heli engine. The square-ish with rounded sides is the regular one to have. PRO versions are ball bearings. THe regular tt36 are not.

I've been looking for one of the heli 36 to try some head ideas with--figure I could get a take out for cheap then make a new head.

You have had several responses here, but let me throw in a third. The stock Thunder Tiger 36 (airplane, not helicopter) comes with two differently timed sleeves. One is more golden in color on top and one is more bluish in color. If there is a rhyme or a reason as to which one falls into which case at which time, I have not worked with enough of these to figure it out. I will pull one out of the box and sometimes I get this one, sometimes that one. There is about ten thousandths difference in the timing, but they are both good, and both can be reworked to make them better. One just needs to know what he has got. It is a good example of why you should measure first, and then decide what needs to be done. And when Randy is making them into his Aero Tiger he doesn't care because he replaces the cylinder anyway.

we have some numbers to cut by so to speak, numbers to make the engine tame for our purposes, i guess the concern now becomes which sleeve do we have because if you raise it .020 and was .010 lower than the other you reall need .030 correct???

That's why I always measure from the top of the sleeve. That way when I set the deck height everything is correct.

Hi Len,
So the *square head* and *round head* versions of the *airplane* series really doesn't matter?
It's the mix match of sleeve/Pistons that is important, right?
I am guessing now, that the two airplane versions are just *older/newer* versions with the same timing. etc., with the apparent s/p combination quirks. (??)
Thanks
Bill

Bill,
You did not mention how much older one version was than the other. There was a series of Thunder Tigers very early in their importation into the US that were very different engines. They look much like an OS FP but at least some have a baffled piston. They apparently run much like an OS Max S. I haven't seen the 35 version but have a .20.

Hi Steve,
I guess those *are* the ones I am wondering about.
I do not have either ones, but have seen pictures of the *square head* version. Am looking to get a couple engines over the winter to go into projects I am building. The only other pictures I have seen did look kinda like an FP. As to running like a 35S, do you mean 4-2 or wet 2 ?
Thanks!
Bill

The "square head" is the current TT36 Pro, a ball bearing, ABC engine. Leonard sells and modifies these, so he is the expert here. The older engines that I have seen were marked III probably indicating Series 3. I have limited running time on the .20 III that I have, but it will run either a wet 2 or a 4-2-4. This is not a high horsepower engine, but it only weighs about 5 1/2 oz. it does pretty well on power/weight. If I ever see a 36 III on eBay, I will bid on it as a Max 35S replacement.

For engines in this size range, however, I think it would be hard to beat an L&J Fox 35. It is very light, and Larry's latest version puts out good power particularly with a 10X6 prop.

I was actually referencing the same case engines. The TT 36 had a squarish case to begin with. If there is a new version out, it may well just be a case difference and nothing else. But the engines with the same case had different cylinders that would appear, and you would know this only when you opened them up.

With the Magnum and ASP 53 engines, although there was a case difference, the insides were identical. If there is a case difference on a new TT 36, I do not have one in hand to compare. So I guess someone who has one would have to tell. But they would also need to know that there were two sleeves to begin with which were already interchangeable with one another.

is this the one that everyone is using?
