"Is that the cat that chewed your new stooge"?.. (I'm goofing..) It had been on my mind that I needed to redesign/modify my launch-stooge. I'd been wanting to make the hinged "U-shape" that I've seen some of you guys use.

I started with a piece of 1/4" plywood. Making the "U" was the easy part..

I had to buy a pair of small hinges.. Rolling Eyes (that irked me.. because I'm frugal..) I utilized a previously-built stooge for its pin-release.. and used the remaining piece of 1/4" plywood as a base.

Here's the finished-product. The two aluminum "spikes" come from roof-gutters. They fit into holes in the rear-plate that are drilled-through at a 45 degree angle and anchor the stooge when used on a grass circle.

There was a bit of trial and error shimming involved.. to get the "gate" to drop smoothly.

The stooge should now work with just about any conventional 1/2A C/L airplane that has landing gear.

even the fork-tailed P-38..

Hmmmm.... Looking at how the red plane fits in there, and how close the top of the stooge looks like hitting the trailing edge of the wing, I get an idea. Have a piece of piano wire that goes through both hinges that can be pulled out from the side to separate the hinges. Have one large U-shaped plate for larger planes, and a second smaller U-shaped plate for 1/2A planes.

Nice stooge ya made yourself there. I also like how it accommodates your P-38! I always wanted a stooge for my 1/2a planes but only one has gear, and even with gear, it is rough where I fly.

Mark

If the model "stood still".. then yes; the gate would contact the wing's leading-edge. The model will move forward as soon as the gate drops.. and the wing's trailing-edge will clear it with inches to spare.

The little red airplane is an extreme example. It may be too small for a stooge-launch. I have a "rail" which attaches to the base-plate of the stooge and acts as a "curbing" for the inboard main-wheel on the model to ride-against. I needed it with the F8F-2 Bearcat to keep the nose from "skidding-inward" on smooth pavement when checking the controls from the handle.

Thanks Chancey! Years ago.. I seldom had a helper or flying-buddy.. so making a stooge was the only way I was able to fly at a moments-notice. I also kept a small roll of tar-paper (maybe 2-3 meters length) and laid it out on the grass for a take-off runway. The lightweight balsa models didn't need much distance before becoming airborne.

I'm still wrestling with a take-off dolly design for gear-less models which would release via a pin-stooge.. and launch the model from an inclined-cradle as soon as enough lift was generated. It would have to be lightweight.. and have large balloon-type tires.. (maybe something like a small pair of Styrofoam-rings Huh... ) and a bamboo frame/cradle? Shocked I started building a dolly.. but it got complicated and too heavy to use on grass.

Surely you'd like the option of being able to fly without a helper.. Small Cox Logo
