RE: Jett vs. Thunder Tiger
I only own one Jett (so far [sm=wink.gif]), a SJ50 with the black SS muffler. Amazing engine. Easy to break in, easy to needle, idles great and runs like stink. I also own a TT46 Pro. Not a bad engine at all, but there just isn't any comparison. The TT with an 8.75x8W APC pylon prop will turn around 16,500, maybe 17, 000 on a good day. The Jett turned over 19,000 with that prop and it isn't fully broken in by any means. The Jett transitions noticably better as well.
As for support, Bob's presence here at RCU is well known and much appreciated. You usually have answers within a few hours of posting. If you need to know NOW, give Jett Engineering a call. Odds are that the man who answers the phone will be Dub himself. Great guy to deal with. That kind of support is hard to find anywhere else.
