Frankly --I see it as a necessary move .
Nitro fuels are simply too expensive for most of the world.
The gasoline engines are still -in many cases - quite undertuned.
Ignitions are now appearing on the market - far in advance, design wise, of the ignition units so common in the USA for a number of years.
This doesn't mean that they are superior for most current applications
But - they can be programmed into curves for responses desired -- tachs can be "built in". and I really expect to see some miniaturization happening fairly soon.
We tried a nice little setup made from very current bits -- where we had the coil mounted on the engine and the electronics literally suspended in a wire to the coil.
It worked quite well.
Al Diem made and assembled it for me.
If we had some better quality miniature spark plugs - then we would be in even better shape.
I am speaking of plugs , the same size as glow plugs -- not the 12mm
An alky and oil engine on spark works very well but current carbs are really not commonly available for this arrangement.
As gasoline and oil tho I expect to see the switch from 1.5 and larger glow - to go to gas - at an increased rate.
Any bets as to when the FAI does shift?
