I'd stay away from the GMS .47 since it often won't shut down/quit running when carb is fully closed. I think its an important safety feature to be able to kill and engine especially if something such as a catastrophic failure in flight (tail feathers falling off) occurs.
The TT .46 is a great engine and equal in many ways to the OS .46fx for less $$. The Magnum .46 is also a very good clone of the OS .46.

Even if they were the same price, I'd buy the TT .46 Pro before an OS .46 FX. The reason: The TT survives crashes 100 times better. (And don't get me started on the remote needle valve.) Otherwise, I doubt you could tell them apart in terms of power, ease-of-use, etc.

I have a Tower Hobbies .46 that is the best running engine I have ever had. I believe the only short comming these engines have is with the carborator. I have seen others who have this engine that don't run as well as mine.

Call me cheap but how can a true spadder be recommending a new engine purchase ?
I've had much luck with used Royal .46BB engines purchased from here and auction websites. I've got 3 now and paid on average 35 bucks for each one. They run great and have almost as much power as a TT .46, about 300-400 rpm less but not noticeable otherwise. If you look at the large auction site, you'll see one that is NIB and it probably will be sold for about 50 bucks-which is still cheaper than any other NIB engine.

BTW, I helped a friend at field break in his GMS .47 2 weeks ago, it wouldn't stop with carb fully closed. Problem still remains and a new engine shouldn't need anything else other than a glow plug and fuel to run good.

True BUT give me a $160 GMS over a $250 FX any day, even if the GMS does need to be sealed up, having said that the TT46, TS46 and Force46 are all about the $160 and i've had no problems with them (Aussie $ used)

But, there's nothing wrong with used engines, but, i wouldn't recommend them for beginners. If you can tune your own engines, and feel confident in your abiities, then by all means go for it.
