Not even considering the difference in price? Same power? O.S.- Easy tuning. T.H.- A total pain the . . .
It's kind of like comparing a Chevy Malibu to a Corvette. Yeah, the Malibu is cheaper. But the Corvette is, well, a Vette!!!
Even if you take the difference in price they 55 AX blows the socks off of the Tower Hobby engine. Yes, you do pay a little bit for the OS name. But in this case you are paying more for WAY more engine. All of the new AX engines (55, 75, and 120) set new standards for engines that others will be scrambling to catch up to. I recently did a review on the 75 AX and all I can say is that this engine is a "Stump Puller". It's easily one of THE best engines I have ever owned. The 55 AX is in that same class. There really isn't much competition for it, IMHO.
