Someone gave me a quart of Brodak's 5/29 fuel a while ago and it runs horribly in 3 different Fox Stunt .35's I've tried it in. It seems plenty oily, but they behave like the nitro content is below the claimed 5%. The engines behave like its a straight alcohol/oil fuel.

I've tried Stunt .35's on 75/25 FAI fuel and they behaved just like this stuff. Kinda hard to start, super critical needle setting, significant power loss.

The stuff smell like there's a touch of nitro in there, but it can't be right...
