how much thrust did you get out of the engine? Also, how much does the engine weigh?
Lasers, jets, and helicopters HURAH!

Thecheat,

Using acetylene it maxed out at 120lbs,but the noise db ratings was so intense that we switched to the propane fuel, the thrust dropped as low to 50 lbs,this engine needs high octane fuel such as acetylene and or nitro methane.

The weight is 22lbs.


Thanks
