Rcmoe,
look up Jenny's RC on Ebay. I think the screen name is *JRC* They part out Btt's and you could probably get a crank for about half price. I got a block with both front and rear bearings and the red gasket for $54 shipped after I sanpped a screw in the backplate of my old block. At 4.92mm you should start looking for a new crank sooner then later.

Hey guys just wondering the best plug to run in a Novarossi S21P5XLT .21 5Port?
Also Wat average run time can I expect out of this engine on a tank, Wat is a good midrange pipe to suit it,and how many litres should I put through for break in before I go to race tune.
Any help and advice would be great thanks

I run the nova 6 plug with an re12. Runtimes right at 10 minutes. I'd wait until close to 1 gallon (4 liters) before getting real aggressive with the tune.

Ok thanks a lot.
That is great run time! Would this pipe/manifold fit the mp9 ok?

Has anyone used the O'Donnell medium plug? The nova #6 is out of stock on amain and a lot more expensive...

Hell yearh! :nod:

OD77T and OD97T are really great when its cold, because they are warmer than Nova #6. They are also great for practise because the engine can idle for month.
