The o,donnell #99t glow plug should work.

Generally The nova C plugs are for offroad use and F plugs are for onroad use.

C = Conical (Is there such a thing as non-conical plug??)
6 - wire
T = turbo
G - gold
F = Cold C = Hot (pin size and body)

You should think of C & F in terms of

O.S P3/4/5 vs OS RP6/7/8.

C = caldo = adjective for hot in Italian
F = freddo = adjective for cold in Italian

the OD99T's were all i ran for years. they are colder than an RB#7
now that i can get the RB plugs i am running them again instead

The USA ran like a mofo today at the track. It's so quiet and smooth with the 2045/192 on it that it seemed kinda week. Then i got on the track with some buggies that had modded engines and i realized just how stout it is. Coming out of a tight corner or at the end of the straight it was running the buggies over. Nice engine. It idles all day. Tomorrow will be a 180 mile drive round trip for rb plugs. This is a tough call since the P4 has been working so well.

If the P4 plugs are working good for you and your not killin em I would just keep running them. Chances are the RB plug is not going to seal in there correct anymore either. Glad it's running good for you, the USA is an engine I wish I could still get!!!! I did find an old crankcase laying around if you do end up needing it send me a PM.

Thanks, Chris. I need it but i've been off work for 2 weeks cuz of my leg. Let me get caught up cash wise. One of my friends has a nib usa he wants to sell.

anyone looking for a brand new b9? email me at [email protected]

hey guys and gals, I have a tm 523, got it with my revo, it also came with a vantage carbon fiber pipe, any of you ever had this combo?

whats a good plug and pipe for a k9 running in truggy with bryons 30

RB #6 turbo plug or o,donnell 97t. RB 2045 tuned pipe

Perfect, you beat me to it, depending on the track size you race on, 192 header for big/long track, 198 for short track.

i have a rb hobby 9 (s5) lg2 with the lightweight orange head its the stock head i took off the cooling head just to check something my question is does the hobby 9 print face toward the engine and the rb print faceing in the back ?
