Quadra 42 what spark plug to use
Older motor that has the rcexl ignition.
It's a small plug.
Plug recoomendations for this motor please !
Going on a ultraspadstik build.
Getting close to mounting engine as soon as the fuel tank arrives.
What plugs are you guys using, I plan on trying a 20x8 prop and an 18x8 prop on it.
Also on the ignition battery, rcexl says to use a 4.8v 800 to 1200 mah battery.
I found a 1100 mah at onlybatteries.com thatis priced pretty good.
