I'm not at all sure what the problem is here. My experience with the TT 46 Pro has been nothing short of outstanding. It is absolutely the most user friendly & cost effective engine that I have ever encountered in 50+ yr of modelling.

While, it is not quite the most powerfull 46 general sport engine that I have experienced (amazingly, the horrible Tower 46 is the winner there), it is sufficiently close that it doesn't matter a fig. My 180 hr TT still starts with one flip, holds a slow steady idle & is close enough to a fully broken-in OS 46 AX for power that you can't tell the difference in flight (this is true if they have similar mufflers -- the stock TT muffler is an amazingly inept device -- loud & restrictive). It is still a lot more powerfull than a new MECOA 46 Tomcat. Seems to me that it isn't worn out yet -- probably not even close.

While I agree that TT parts are expensive in North America (and apparently so in Isreal), that is not the case everywhere in the world -- they are cheap in Asia -- making the engine a sure-fire candidate there for re-building -- if it ever wears out. At 200+ hr lifetime (or 400+ hr according to Dr Nitro), I don't care if it wears out. 200+ hr is about 1,000 flights (or an amazing 2,000 flights at 400 hr) -- it doesn't owe anybody anything at that point, plus the case, carb, head & crank are still usefull as spares.


I have owned a lot of engines by numerous manufacturers & in a wide range of sizes & end-use configurations. There are a lot of them that I wouldn't buy twice, but based on my experience to date, I would buy any TT product in a heartbeat.
