Seems low, my Thunder Tiger GP42 will turn a 10X6 Scimitar to over 13,000. The Pro is a very powerful engine. What brand prop is that?

Its set fairly rich, otherwise it will overheat, anyone else have that problem. Oh, and the fuel is a year and a half old.

there is your problem change fuel and plug and then should have a much better engine. I think most LA 40 type engines will spin that at 12,000-13,000

Hi!
A TT .40 PRO SE turns a 10x6 RAM (British prop, best prop) at 14800rpm using 80/20 FAI fuel.

Ijust picked up a well used TT 46Pro and with little effort I was able to get 13,800 from a Master Airscrew 10X7 on 10% Omega with added castor.

I got 14,200 with my TT .45 Pro ABC. MAS 10x6, 10% Sig fuel, Stock muffler. This is a very smooth engine! I'm going to put a Jett Stream tuned muffler on mine.

I got a few more numbers. On 5%nitro 20% castor homebrew, Jettstream muffler and fuel tank about 7" below engine I got 16,750rpm on a 9x7 and 15,800rpm on a 10x5. Both props are APC. I think it has a little more to give.

Maybe you guys can help me out a bit. I just bought a used TT Pro .46, it's in great shape except the innards are gummied up. Once I have it apart, I can get it cleaned up, but I have a problem. How do you get the whatchamacallit off??? (thrust washer to be exact, see photo) Just out of curiosity, where can I get new bearings if I need them? Thanks!!

I had a bear of a time pulling the prop hub off of my TT .46... I would spend the money and get a prop hub puller. I plan to do this also as heating it up and banging on it with a piece of wood isnt the ideal way to do it. (I replaced my stock metal-caged bearings with phenolic caged bearings) I got my TT .46 bearings from RCBearings.com for about $11 shipped. You may want to soak the bearings in acetone or something like that to loosen the castor crud up before replacing the bearings... They may still be okay. Usually a gummed up piston and carburetor means the bearings are gummed up too. Castor crud looks much like rust does, so they may come squeaky clean and turn smooth just by cleaning them.

Thanks, I got it off last evening after someone pointed me to a video tutorial. You're right it was a BEAR, even after heating it several times, it still took some serious pounding to get it off. I think I'm gonna replace the bearings, it has the original metal caged bearings, and I'm not hearing good things about those. Bearings aren't expensive, so, might as well.
