The previous Tower Hobbies engines were made by MECOA right here in the good ole USA. The company is Model Engine Company of America there in California and they had the contract to make the TH engines for Tower Hobbies. Also the TH engine has a striking resemblence to the GMS engines but it is a known fact that MECOA made the Tower Hobbies engine for Tower Hobbies.

See MECOA makes and has rights to make K&B, RJL, HB, HP, Fuji, GMS, and MECOA 40 and use to make 60 size engines and various of other "older style" engines simular to the old style ignition engines. Randy Linsalto (I hope I spelled his name right sorry if I didnt) and his wife Lin own and operate MECOA. From what the web site shows is that MECOA has had to move to another location so maybe perhaps some time soon that they will start production of the TH engines and other engines that they are famous for. I'm not a K&B engine fan but I have had the want to getting me a K&B 60 engine and send it to Clarence Lee for his mod that he does to the 60 engine.

Just for a added tidbit Clanence Lee had a hand in making or creating the K&B engine that was a quickie 40 size engine that as soon as the engine was built the engine was started and had a "RPM Goal" and if that engine didnt meet that minumum rpm the engine was dismanteled and scrapped and another one was built. (Credit to be given to a acticle that I read I believe from a RCM magazine that is no longer in circulation. If it was not RCM then maybe Model Airplane News magazine.)
