O'Donnell Plug in a .12 Nova
 

Hi guys, quick question here, would an O'Donnell plug fit in a novarossi .12, the novarossi plugs are good but the prices are a killer. We use a hot plug, normally C6TGF, do you guys thing the O'Donnell #77T would be a good replacement, if it fits that is.

Thanks

mate i have been using o'donnel plugs in my nova 3sct as well as in my rb tc10 and in my opinion they are better than a nova plug (at least the ones i have used) also i have found them to last longer and easier to tune but that is just what i have found not saying novas are bad.

yep, have used o'donnell 77t as a substitute for c6tgf plugs and had no hassles.....good replacement

great, thats good, thnks guys. gona buy me a few 77t's now

is the #97T plug also a good plug for a nova or is it too cold?

O donnell plugs
 

i now buger all a bout plugs but i use them because of price alone 77 / 97 are about $ 3.00 each or eaven better from tower hobbys if u by 10 or so also i have never had middel fall out like nover

I have always run the 99t in my RBt10RC and my Nova Flash. I would normally use the nova 7 plug.

Plugs and O'donnell Plugs. I have good success running these plugs. They are really durable. With standard head shimming from the MFR below are some comments I have about the O'donnell plugs.

77T - Pretty Hot plug. If your running 16% nitro this is probably the right plug to use or the 97T. I probably wouldn't run this plug with anything over 20% nitro.

97T- Between a Novarossi 6 & 7 plug. These seem a little hotter than a normal 7 plug from Nova, but not quite a 6.

99T - Pretty close to a Nova 7 plug, perhaps a little colder.

These have just been my experiences..... of course others may have different experiences.

if you can try the exceed's which i believe is the previous GRP, it is even much better.

I think the 77 would be perfect for me, 16% fuel, humid hot temps here as well, btw, have u guys checked out the price of these plugs on towerhobbies, insanely cheap, just on the price it tops the nova plugs.

Tower Hobbies has these plugs @ $1.39/ per plug limited Qty. The 99t's are out of stock. So I got some 77t's and 97t's.

Can these plugs be use on O.S. engines also??? I have a Mod O.S. Maz .12 TZ.

OS engines use a different taper. I would say no

Cat's out of the bag!
 

All of us Timezone guys up here in the Northwest have been buying up the 77T and 99T from Tower. They are great plugs and for less than $2 a pop there is no comparison. Just go buy 24 and be set for quite a while.

A different taper or different depth? I've never seen 2 turbo heads that use different threads or different taper?? But I suppose it's possible. I've run an O'donnell 77t in an OS 12TZ tho...
