If you can't stomach the price of a new .46 AX, you'll find the Thunder Tiger Pro .46 to be just as easy to tune, just as powerful, just as reliable, and it comes with a better warranty. Long time RCU posters in the Glow Engines forum also report that the Pro .46 will considerably outlast the .46 AX as well, running twice as long before needing a new piston and sleeve. The Thunder Tiger Pro .46 typically sells for around $95.
I also like the Magnum XLS .46A, and think it is a terrific bargain at $59.99. I'm not sure it's quite as powerful as the Pro .46 or .46 AX, but it is very close. It is also easy to tune, easy to break in, and dead solid reliable.
Thundertiger is a great engine, I have several. But the service is almost nonexistant. You may never be able to get warranty work, or it will take 8 month's to get it back as I did. So I no longer buy or recommend TT.
I HAVE A TT 40GP THAT I CRASHED......PUT IT IN A NEW PLANE BUT IT WOULDN'T KEEP RUNNING. I SENT IT IN TO TT & TOLD THEM WHAT HAPPENED. I GOT IT BACK IN TWO WEEKS WITH SEVERAL PARTS REPLACED AND TESTED.... NO CHARGE , NOT EVEN FOR RETURN POSTAGE !! I WAS IMPRESSED...WENT OUT & BOUGHT A TT 46 PRO FOR ANOTHER PLANE.
