RE: Plugs of Choice for Speed Engines
i have used KB1-L for smaller engines and my pattern planes, but i like the Merlin plugs alot, and i prefer the flat wound element plugs for high nitro and high rpm, they are called globee style, i used globee flat wound types for my 50 plus nitro engines. the plugs took at least twice the amps to light up. enya four stroke plugs work very well as well, but are very expensive. K&B HP plugs have been the favorites of the ducted fan guys for years, unless they were running a nelson engine.
