Title: Magnum engines and similar engines?
Post by: frank mccune on March 26, 2013, 07:45:07 AM
     Hi Folks:

     I have a Magnum engine that I have been told is an engine that is sold under various names.  Parts from these other engines will drop right into the Magnum and are very easily obtained.  What other names are these Magnum engines sold?

                                                                                                    Tia,

                                                                                                     Franchi

T.T., Alias Thunder Tiger.

I got my first .36 Square head, ball bearing engine with Reccomendations from the combat troops. Alas, they couldn't use them because when measured, they were actually oversized (.365+?). Put a Randy .40 pipe on it and it was terrific! Next time around they are being sold with a Thunder Tiger logo. I understand they are/were made in the same factory.

It might depend on the vintage.  Some of the ASP engines are the same as the Magnums, just a different name.  Better to stick with parts for the engine you have than to risk buying a part that won't work.

The OLD Magnums before, were made in Taiwan by Thunder Tiger, that was before Thunder Tiger was sold here, Magnum was a start up in China and built their own plant and made the newer Magnum motors, The were all Magnum and not the Thunder Tiger made ones from years earlier. So the older Magnum 36 and the later versions 36s did not share parts, except for a few like bearings.
By the way when Magnum started to build their own engines, that is when Thunder Tiger imported and sold their motors in the U.S.

The first Aero Tigers were made from Magnum 36 engines that were produced by Thunder Tiger in Taiwan.

Here's a quote from Sanye, the Chinese company that makes them now:

"In adition to SC, ASP, and Magnum, Sanye, the manufacturer near Hong Kong in China, makes the glow type Evolution engines for Horizon. They also make many of the parts for the RCV line of engines. "

I can tell you from personal experience, the later "square head, small case" Magnum and ASP .32 and .36 engines are identical except for the small rectangular emblem on the bypass part of the casting.
The Evolution: not so much

So Randy;
           Were those initial Aero Tigers made using the "round head" Magnum 36 with the longer stroke and smaller bore?

NO  there was  no round head Magnum back in that time frame, the first Magnum 36 engines were made by Thunder Tiger in taiwan, and were not round head, they were square head

Thanks Randy. I was just curious.

The Magnum engines were made in Taiwan  for many years before they redesigned them and started up the production at the China plant. When Thunder Tiger made the Magnum engines, they also made and identical motor called  ROYAL, those had all interchangeable parts , and were very close to the FSR  OS engines.

 I saw an INC. 40 engine yesterday on Hobbyking. Some users had good comments. They also said it resembled the Leo/Royal.some said it came from the same mfg. after the Leo run was finished. Anyone tried these, fairly inexpensive, not sure how they are weight wise.

They are too heavy and when you add the cost to get a NVA and a custom made Venturi the cost end up the same as most 40/46 C/L engines, like a Enya SS40 S for example that is much lighter, with better timings and needs no parts to be replaced. Also I bet the china ball bearings will not last for long.

So to me it is nonsense converting these R/C engines into C/L. Not to mention that when getting a legitmate C/L engine, specially from a C/L hobbystore, you are sending funds to companies that actually cares about making and providing C/L products.

I'll try and re post it as close to what i wrote.

The Royal engines were not made by Thunder Tiger but by Leo engines which is owned by either a son or relative of Ai Ling the owner of T.T. their offerings also paralleled the OS line very closely and probably were mistaken for OS more then once.
As to the Magnum that was a trade name owned by Hobby Shack(People) and they were made by Thunder Tiger. They did not sell their engines in this country at that time I guess because of contractual obligations. Hobby shack and Thunder Tiger parted and went on their own way with HS retaining control of their engine trade name Magnum. Thunder Tiger then started selling their engines in this country under their own trade name. Magnum is to the best of my knowledge still sold only by Hobby People.

How about posting a picture of this "Magnum" engine? Otherwise, all we're going to get is a lot of conjecture and supposition, and still not know which this one really is!  #^ Steve

The Royal engines used many parts that were the exact same part as the TT made Magnums, because they were made by Thunder Tiger.
I sold both lines in the late 80s early 90s, They were brought into the US by Global Hobby, and I was a U.S. Dealer for both of them. It maybe that Ai Ling's relative bought his parts from TT, however they were many of the exact same parts.
I still have many parts and even a few NEW Royal engines and TT made Magnum engine and parts on the shelf, many are identical with identical marks on them.
 The reason Thunder Tiger could not, or did not sale Thunder Tiger engines in the US was because of a contract they had with GLOBAL not to. It made sense untill it came apart  and GLOBAL switched, or had to switch, the manufacturer of their line of Magnum Engines  to China.
And YES as I stated earlier in the thread, they were very much OS Clones, you could even use the parts of either Royal or Magnum in the OS FSR engines.
And Magnum was  NOT only sold by Hobby People, I (AERO PRODUCTS)sold them, many 100s of them, as I have for the past 3  decades, both TT made and Chinese made versions.
