Here are the photos of my launching stooge I built, I use it for solo practice flights.

The platform was bought as a middle size camping folding table and with one side legs folded it provides a positive angle needed to safely launch a model. Fully folded it easily fits to my car's baggage compartment.

The launching device itself is very simple and made of piece of long nap carpet, folded at one side and wing shaped with bolts at the other side. The bottom part of the device is nailed to a wood frame for better durability and the wood frame is mounted to the table with bolts so if needed you could easily take the launching device off and just use the table.

To launch a model you need to pull it out

The stooge's bottom just nails to the ground...

It's a plastic BMX ramp I've had kicking around my back yard for the past year or so.
Good angle of attack hey..... Haven't tried it yet but hope to tomorrow night.
I'll post the results & maybe some pics if it all goes wrong.....

Had 5 flights out of my stooge tonight & I'm happy to report it worked well!
Will probably take a few more goes to get the hang of using it fully but I think
this type of design is simple & effective.
One thing I did do was use a tent peg to secure the handle wrist tether to safeguard
against any unwanted launches...
Having said that the model seemed to be held in place pretty securely with the engine running
but was quite easy to pull out for thr launch.

Hey! Congratulations man! Welcome to the independent solo fliers club!  Grin
Nice stooge, I'm glad it worked for you as well.
And thank you for the photos!

Hey nice "stooge" man!  Shocked  Cheesy

A couple of weeks ago I had a visitor - combat pilot from New York, he showed up with his wife and we had some combat practice. Well, his wife and mine were launching the planes! That was the show  Grin
It's pity there was nobody around who could make the video or just take a photo - it would rate the photo as a number one!  Wink

Hey! Here is one more design from Randy Eckert (Salisbury, Maryland, USA) very good modification to be able to launch F2D planes as well as the FAST ones. With his permission I'm posting his e-mail:


"I built the hold down as a modified parallel clamp using (2) 3/8" x 4-1/2" carriage bolts with washers and
wing nuts and (2) pieces of 1"x2"x48" white wood -cut to size. This clamp style
works well for me because all of my combat planes F2D and FAST have the style of
tail where there is an airspace between the trailing edge and the elevator.  The
holding pocket is a 24"x48" piece of carpet remnant. This setup will allow me to
launch my F2D planes and then reposition the clamp to launch my FAST combat planes
or other varying size planes. The table folds in half to a dimension of 24" x 24"
and has a built in carrying strap making it very portable and the legs have 3 height
positions so when it is not at work at the field as a stooge I can remove the clamp
and carpet and have a good working table..."


P.S. hoping to get a better photos from him, so we could see the details...

I must admit - very good design, as I can barely fit my Speed Limit planes into the carpet pocket I made. So I think I'll upgrade mine to this design so I could slide the clamp up and down to be able to fit the larger wing planes

Well done Randy and welcome to the Independent Solo fliers club!  Grin

Hey everybody! Randy Eckert sent me some high resolution photos, so you could see the details of his sliding clamp thing. And also here are some comments on it:

"Please note one other small detail I had on the clamp- I put a clear piece of 9/16" O.D. x 3/8" I.D. vinyl tube around the threads of the carriage bolt that resides next to the plane. I put the tube over the threads as a safety precaution to keep the threads from inadvertently "digging" into the trailing edge or tail section during setup."
