HI Brian .THX for your advice on this one I was surprised when I took it out of the box and saw the small 10 inch prop with it will go get the larger one biggest one I have now is a 13x6. Back when I was a kid the drone was my first and only engine I had and did make up the 75/25 fuel mix, it brought back memories never an issue with it as I recall over many years an moves it sadly went missing martin

the small prop wth it appeared to be a pretty high pitch maybe a 10x10?? or higher pitch?? if they made them back then

I was out of this hobby for decades when I started again my first engine Irvine 40 diesel and then of course other diesels never bought a glow battery till I got some 4 strks
my davis conversions contrary to custom never saw glow fuel no issues ever it just took a few more tanks to break in no diifferent glow fuels plugs to match etc
