Kris, no mention of the radial mount or the plug adapter didn't like it?
You stated:
"My best version will do about 21700 rpm on the Cox 4.5x2 prop (and 10% nitro , but even the hottest Turbo plugs from OS are colder than the stock
glow head, so the throttling suffers and the engine tends to run very hot..."
Do you have any video of those results?
I just used an
OS RP6 -
medium heat turbo plug - and it out performed the stock plug with fantastic idle response, see video below for proof.
Skin Effect:
As Voltage pushes the current density is largest near the
surface of the conductor and decreases within the core of the conductor.
Silver is the best conductor of electricity because it contains a higher number of movable atoms.
Silver it also has the highest thermal conductivity of any element.
Gold has a much higher corrosion resistance.
