4 of those and some duct tape and you can make the table fly off! :D

Sorry Satisfaction, but some rotary engines do have pistons. Look at the Gnome and Bentley engines of WWI. This engine also has pistons that look just like those in your car. These are actuated by a cam instead of a crank. They rotate around the cam and everything is in balance, thus it is a rotary engine.

I'd grab that thing and chase the damn neighbor kids off my lawn

@SuperEdiggity The rotational moment of inertia of the rotor is slightly less than that of the 22" wooden prop you see mounted on the engine.

im curious to know what kind of torque/gyroscopic forces this would make in a single engine aircraft in flight. wouldnt it make it hard to land? (student pilot here and am serious i really want to know hahaha)

@DepakoteMeister There's another video of it running with the cowl off so you can see the radial cylinders rotating. Just go to a web site called (modelenginebuilder.con). Scroll down to issue #15. Click on that, then click on Jerry Hale rotary.

How to we know that's not just an off the shelf model radial engine?

@pissedatpez or you could just go buy a rotary powered bike, they're not new. ;-)

@DJHale68 That is a really cool engine. It seems to have some potential for a wide range of uses. I could honestly see it being used in small industrial equipment (e.g. generators, lawn maintenance, and welding equipment) not to mention aircraft. I say that because it appears to be capable of idling at a very low speed and with injection, maybe even lower. Very interesting. I wish I had that talent.

@phantom0482 no its a rotary because the pistons rotate

[crudeoilsystems]

looks like fun

[phantom0482]

if i'm not mistaken... isn't this a radial engine... not a rotary... still a very nicer running engine though
