+1 I bought this motor for a back up and ran it as my race motor for the longest time. Now im running the nova 21-4 motor and have two n21bf's for back up. I would say for the price this is prob one of the best motors for the money on the market. Im fixing to have Monty Put his magical touch on one and see what the little thing can do.

Man quite a few choices for the plugs. It looks like the od 77 is the front runner. Is the nova plug that much better than the od 77.

Are these the right plugs for th nov .21 limited. If they are they are cheap. 4 bucks for a plug.

You really want a medium plug in these, particularly if you are running 30%. I believe i'm on my 3rd MC8 plug (including break-in) after 2.5 gallons. Idles like a dream, and I have not flamed out since I put this engine in.

They'll work fine, and actually tower hobbies has them for the same price and when you get six, it goes to 3.65 each (plus 4.99 shipping)
Edit: amains shipping is 3.65 so you only save about 1.40 at tower. I can find lots more stuff at amain so i dunno
