Sorry for being such a newb, but can I race and run using all Trailing Spark Plug for the trailing rotor and the leading rotor... Will it effect anything like that..??
Or for the Trailing rotor it'll have to be specific plugs for the trailing and for the leading it'll have to be specific leading plugs for it...??

 

Many people run 9's all around.

 

thanks Mahjik...

 

9s all around are what Peter Farrell recommended and they work just fine.

 

yep that's what I'mma do..

thanks tcb100
