Hy all
Is there a .46 cubic inch NOT 46cc motor that runs on gasoline NOT nitro? Nitro is to much $$$. Thanks

RE: .46 cubic inch
A .46?
strange --up till late 1940's , all model engines were spark ignitioned and ran on a mix of motor oil and gasoline
some were pretty good runners but the interest in these is all but gone -just collecters n free flight guys
here is my .14 cu in Marvin engine from way back when. If you could lay your hnds on an old Mc Coy, O&R,or similar engine you could adopt one of the inexpensive Chinese ignitions and actually go flying -a very light model such as the SiG Seniorita could work. . My first model engine was a .09 ATOM gas engine , with a glow plug.
Using a new radio system such such as the Spektrum 2.4- one could also fly, using one of the old open point gnition systems - maybe - I would hve to do a check first but if the spark plug wire was tight -it should work. These new radios are pretty immune to low voltage spark noise.

RE: .46 cubic inch
We flew radio assist old timers in contests for years using McCoys, Anderson Spitfires, Super Cykes, ETC...Points ignition, Kraft and Proline AM radios...The spark plug wires just clipped on the top of the spark plug...We put a small resistor in the lead, right at the plug..Worked fine, I could get the plane so far away it took a helper with binoculars to see it to be able to keep it under control...With the new shielded plug caps from C&H on the 1/4-32 Rimfire plugs there would be no problem with RF...Problem with these would be fitting the 6 oz of ignition and battery in a small airplane....
Fuel is not a factor, but it takes more oil if you use gas....
