Ha, the plug died with honor.

In the quest for speed,I've been foolish to assume that the nitro is the quick way for a power boost to give me some more get and go with no trouble.

Trying to reduce different types of fuel/nitro content, I was hoping this could cover more types of my engines. humm More 10% needed.

I use my ear and get my engines singing on full tank and then back off a couple of clicks, then launch, its never rich lauching, its on song, so it powers out of my hand.
If It dies to early into flight, I rich click more. If it guggle at all in flight its rich., so lean click a few or less.

I let it run out of fuel and land. Maybe the end of the run when the engine leans and dies, does it blow the plug????
Should you land before the tank empties to prelong the life of the element?

Never tried a bubbless tank-I cant find them in uk. I see Mike made his own.

Engine fixed with hex screws into individual plastic mounts.

Prop 8x6, good for it im told. Would like to try 7" diameter. I notice apc 7" hubs get alot smaller than 8". Better to to cut down 8" down to 7"???


Heat range, Trying to understand wether shorter manifolds/pipes ment hotter engines, Ie manifold too short? Power/rpm decrease and hotter engine?
