(SNIP) i have a italian 61 super tiger motor on a bel- air biplane. the plane is a great flier. the st motor runs great. i have had the ones from china too. compaired to the st i have the china ones ....suck. it's a shame they couldn't match the italian ones. i been flying this motor for two years now. i wouldn't trade it for 10 engines made in china. i will never sell it. it starts and runs like an electric motor. just wanted to let you know. look around for one made in italy. you won't regret it......RON
There is a bit of HISTORY here. In June, 1986 +/- (forget exactly) World Engines, (John Malony) the importer of O.S. and S.T. was going bad medical-wise. His Heirs were not interested in keeping WE or their subservant Indy RC going so John sold "Great PAINS" the import rights to OS and ST, for 10 Million yankee greens.
GP took the mfg tasks to China. Sad as WE had some great engines for different types of modeling. GP stuck with the everday sport flier. Those STs that have a bolt-on front case are absolutely the best of ST.
There are smaller excellent engines but for the .60 up, the bolt on casers were - and still are - far better than anything GP has to offer.
GP made out as GP cut the STs down to poorer quality and thus no competition between ST and the HIGH PRICED Spread, OS. [:'(]
Tower, at first a small college-kid side business, was assisted by B. Paul (very big distributer in Philidelphia, PA) to get big and set up Great Plains, Distribution company.
GP had some big money backing it up, so they went out like Sears and Roebuck did, in and after WWII gave big contracts to all the small manufacturing companies that no longer held government Defense contracts. When these small model airplane kit mfg. people received big orders from GP, they kind of deserted the normal mfger. wholesaler retailer ways and went right to the dealer and hobbyists, and now the dealers are suffering and sliding off the trailer. Great "PAINS" and Tower is getting a taste of their own medicine and so will all the hobbyists do same in the not-too-distant future.
As far as the Super Tigre, the .15, the .23, the .29 all were great little power plants.Where are they now? I have some, Do YOU?
Super Tigre, before GP, provided a restrictor for the carbs for .35s and .40s and possibly the .45. Without the restrictor the current .40s are a bear to get tuned, With the restrictor they are a *****-cat. I made a number of restrictors for club members. All stated that the restrictor did the work big time. I asked GP why not include them in their engines. NO ANSWER, NO DISCUSSIONS. I run STs in all sizes except the 2000 and 2500 but I own a 2500 still in the box for years. I get every ST .60 (61) Blue-Head I can find on eBay. No idea why because they are nearly impossible to wear out. The .75 is a fine engine, but for some reason the .90 sucks.
IT's all in the money. GP alaTower has all kinds of OS engines. OS is the prima-dona. Look at the price of a truly fine engine, thunder tigers, priced ahead of like OS. When GP bought ACE RC, the TT went from $50 to 150+/-, then shortly back to $100. They do protect the OS line.
Had enough? Never meant to go this far! Have a Merry Christmas and all kinds of nice holidays.
Forgive me all the typos and even be nice GP!
