Is anybody familiar with one, and can you tell me exactly what it is?

Thanks,
Pat

My airplane weighs 2 1/2 pounds and is powered by a .15 engine. It won't launch from a stationary position.

Stooge wouldn't be the right terminology. What I need is a catapault.

I saw a thread in extreme speed airplanes that mentions the use of a dolly.

I find that a good underhand shove with my left hand allows me to have my right hand on the sticks plenty quick enough.

Obviously, the control line stands like pictured above just don't work in RC.

Status: offline 		I does take some time to get used to it, but after awhile it becames second nature. If your plane is trimmed, you don't need to do anything with the "sticks", just through it slightly above the horizon and it will fly out just fine. Alot of right handers launch with their planes with their right hands and hold the transmitter in the left, then while the plane is flying off, bring their hands down to work the sticks. I personally like to have a right thumb on the right stick while I'm throwing with my left hand...

Status: offline 		I'm guessing your wingarea isn't very large then, meaning that your wingarea is going to be fairly high. Also, what prop are you using? When we throw our SSC planes, which weigh a MIN of 2.5lbs and often are closer to 3lbs, we have a lot of wing area giving a wingloading around 12oz/sqft, and an 8x3 prop. The prop gives lots of thrust, and the wing area means a low stall, so the handlaunch is pretty easy.

If you are using a higher pitch prop and a higher wingloading, you're going to need a much harder throw. In that case, a catapult or a friend with a strong arm really is going to be your best bet. Be warned though, I've yet to see a catapult that was 100%, they can and do mis-fire.

Status: offline 		I fly rippers, I just hold the bottom of the plane in my left hand and I move the throttle forward with my lips and throw the plane, this way I have my right hand on the stick I use the most I rarely use the throttle.

Though the top one and the one in the middle might, if you have a high enough power to weight ratio. Back when the scale RC Combat planes were smaller and more highly loaded, they used catapults. I saw some at Muncie when they had the Nats demo event there (I think it was 2000). One or two planes that were hand launched snapped in upon launch.

One thing I've thought about was taking a cue from the model rocket folk and using two or three carbon fiber launch rods running in tubes which are attached to the wing. Or use four rods in a "tower" - the wing rides between two rods on the left and two on the right. These rods would be just slightly nose up from horizontal, though, not vertical like the ones they use for rockets.

Not that some kind of unassisted rail launch system couldn't be useful.

Btw, when hand lauching, one of the best things you can do is put on something to make the grip better. I've been using sticky-backed stair tred stuff from the hardware store. Even when oily, it makes gripping and getting a good toss a lot easier.
