For many years the Missouri Air National Guard had an F-100 on a stick at their entrance.

Why is the gear down if that aircraft isn't going to need to roll down a runway?

It just increases drag for the RATO launch.

maybe in case of bad take off.

Could be that once they got it mounted the gear was blocked, or it could be awkward to manipulate gear-up. Or it could be that more money was required to do it gear-down... ;)

That used to be a very common solution for starting those beasties. I guess that's a chain-driven PTO. A lot of Russian planes had notches in their spinners. :)

Reminds me about starting model plane engines, spinning it with your finger, getting smacked by the prop and finally figuring out that a battery and small motor could spin it

I still have a box of Cox .049 and .032 engines and the scars to go with them.

I used to get blocks of Balsa and attach long wire mounted fat model tires to it, four tires at the corners.  I would then mount an engine on the back end of the block with a fuel tank.  Then I would start the engine in the church parking lot (empty, of course)  and run like hell to a high spot, then watch this "thing" run all over without any guidance.  It was fun when it took off after a neighbor kid that thought he could catch it.

What about the ones that ran with a little CO2 cartridge  in a hole in the back....JET PROPELLED

CO2 cartridges were for the wimpy.

You'd be surprised how fast a Revell plastic model of a Mustang can go with two Estes rocket engines attached.

Never claimed it would go straight.

:biggrin:

They were neat, but didn't run very long.

A friend of mine had a small displacement model engine that ran on CO2 cylinders.  I thought that was so cool.

At the model airplane meet in my hometown's airport, a guy had a pulse jet with wings and tail attached.  We had to get below the cyclone fencing in case the cables broke.

He got it started and leaned back like it had a tremendous force and around it went in a circle, loud as hell and fast as also.

IIRC we flew those things on a "tether", zround in a circle....then came the remote control ones..
