Ofna nitro engine

[Sledman3064]

I have a ofna nitro engine that has a 3.5 on the side of the motor and I don't remember if it's a .26 or a .28 I'm also trying to find a 3 or a 4 clutch setup that has the flywheel too. Thanks

@Sledman3064 that would be a .21

Losi makes a great 4 shoe setup that is very easy to maintenance. Only issue would be having to run the losi clutchbell. Highest they make is the 15tooth.

just FYI, Force uses the same casting between almost all their big blocks. so even though it does say 3.5, it still could be a .26, or .28 or .21.
(this is true for the side of the block, the top of the head should be the correct size unless someone fit another to it.)

It's got a different head on it

What are you using the engine on?

All you need is a 3 shoe set up ,you can find that on Ebay pretty reasonable ,you would need to find the proper gear ratio
on the clutch bell for your application!

It's on a kyosho usa 1 that I bought over ten years ago

Do you still have the clutch bell for it ,an if so ,would it be single or 2 spd gear bell?

 

[Sledman3064]

Yes I do still have the clutch bell it has a single speed

Ok ,yea ,some of them dabbled in to 2 spds along with chain drive!
But any way ,you can use any 3 shoe set up ,make sure that you get a new corn with a flywheel & shoe kit!
The thing with Losi ,is their products are more expensive ,an you would have to buy their shoes every time
you have to replace them ,with the ordinary brands like Ofna or Kyosho ,most interchange with each other
an are more universal!
A 3 shoe would probably be best ,given the size an weight of that truck!...

"corn"? That a typo for collet?

Thanks for pointing that out, @olds97_lss.
However, with the right SHOE kit you shouldn't be getting any new CORNS.
