PLease help me to check, Thanks!!

one more thing, what is the good plug for ofna force .26 engine ? Thanks very much for help!!

No, I think the backplate would be too small. Ofna does have a similar product though that would work. Hold on a sec while I dig up a link.

the plates are the same size but the OFNA one has a better placed input area for buggies

Not sure about that roto start. But Im using MC8 and MC9 plugs in my force .26.

Thanks for answer my questions !! Really helpful !

If i use the ofna plug wich come with the car, (this is the one http://www2.towerhobbies.com/cgi-bin...?&I=LXGPN3&P=7 ) should i use only one Copper Washer or two ? Thanks very much !
