RE: OS 46 ax VS TT pro 46
I am a big fan of the TT pro 46. One of mine hasd been through two SERIOUS wrecks and still runs like a top, even being over ten years old. I am curious though. Where do you get a upgraded bearing for the TT for high RPM use. I plan on sticking mine in a high speed SPAD Sickle very soon so i would like to take care of this now while the engine is just laying around.
The OS is one heck of a motor as well. Either way I think you will be happy.
