I know you must pay outrageous prices for nitro in your part of the world. Here is a setup that may work well for strong performance with lower nitro. The spark ignition makes the engine
behave like it has more nitro than it really does. CDI ignitions are cheap now.
Edit: This engine uses regular glow fuel, not gasoline.
Aerobear,
Nitro is not that super-expensive here but anyway heats the engine too much if it is more than 15% whatever the
engine type is; of course in the Finnish winter more nitro makes it "warmer".
The Big Problem with Nitro for me is that it "Eats" the construction of the airplane unless the whole model is done
by fiber-glass but that is not the usual case. Even if you have resonance pipe,the spill of fueloutfrom the carb
will go over the model and "wear-it-off", not to talk when there isn't a pipe which take the exhaust away from the
model.
As for the ignition, look a good idea but how the RPMs are different, meaning, could you please post what is
the best with ignition versus what is the best without ignition and tell the nitro content ?
Also, to implement the whole thing needs too much time and effort which I guess this ST engine does not
really deserve; I would buy better engine and keep the thngs as simple as possible. Anyway, congratulations
for the effort, you seems to be a ST-fun. I am too, still keep as Holly my original Italian 2.5cc and 7.5cc ones
while those Chinese versions seems to have lowered the performance.
And also, please post the scheme of the fueling connections.
