that should point you in the right direction!

I guess it won't work, I don't think that engine has a turbo head.

i think i liked a A8 os plug in my rg.

Should I get the O.S. 21 RG or O.S. 21 RG (P) or is there any difference?

I think the (P) is just for the Pullstart engine. If you plan on using a starter box, Get the regular one. The lack of the pullstart backplate frees up the engine for better performance.

RCDad · (#31 (**permalink**))

Neither one have a pull-start. Ok this would be funny if it were the difference, the (P) version says it comes with a poster

Edit: the crankshaft is longer on the (P) version 30mm compared to 22.5

Sorry for the endless babble but anyone have comments on the Ofna Hyper .21 8 Port Race Non-Pull Start SG?

DAVEC-NITRO-RS4 · (#33 (**permalink**))

hyper 21 w/OS Carb

I know George had one for sale, and it might still be....

RCDad · (#34 (**permalink**))

Man, I'm not sure what is more painful, choosing which engine to buy or a root canal.

Anyway, I finnaly said the hell with it and got the .21 RG (P). The (P) version has the better carb I believe.

I went ahead and ordered a crowd pleazer body also, time to ditch the Stampede body, since I painted the outside everytime I get fuel on it the paint comes off

Anyone know the Werks racing clutch will work with this engine?

Hyper 8 port race is a great budget motor....very fast and very affordable. RG won't be as fast but it'll be fast enough!

Obsessive R/C · (#36 (**permalink**))

The Werks clutch should work just fine.

RCDad · (#37 (**permalink**))

Twisted Toys (for those of you who know him) said the buggy Werks setup is what I need so put that on order. Now I'm wondering if I need the same Ofna CB I had to get for the Savage Werks setup?

I may get one of the .30 OS engines for my Savage.

rocco79 · (#40 (**permalink**))

Ive heard very mixed reviews of that engine

RCDad · (#41 (**permalink**))

True. I'm not always a believe that bigger is better.
