Also the # 8 plug is hotter, and likes that better than the A3.
Are you sure - on the os website they say the #8 is medium hot and the #A3 is hot.

Thanks. Yes it does appear that way. I was told that the #8 is a hotter plug though. It (LA 40) does seem to prefer the #8,
but that may have been caused due to the degraded condition of the A8 plug it replaced.
If the #8 is a cooler plug, then that makes sense. Higher cost=thicker element, although if an A8 is a hotter plug,
it would likely be shorter life, contrary to the description given at their site, describing it as a long life plug.
As far as the props, my Duraplane DT 40 will barely get off the ground with a 10X6. It is overweight due to some mods.
Before I moved up to the 11X5 there was hardly any throttle response, tons of lag, etc....
