I assembled a Supra using a Mike Lachowski pylon, a Goodwinds tailboom and Will Lipscomb wings and tail feathers.

Iíd like to say another Supra build is finished, but itís really another assembly job finished, since I just purchased the parts, sanded and glued them together. I got to make choices about how I put in the electronics, some small construction details and then go cool down my poor overheated brain. So what? Well, each of you could do the same, inexpensively. (After all, how much does a bucket of cold water cost.) Seriously, thereís an opportunity to fly a composite (bagged wing) Supra at half of what a commercially made one would cost: a significant savings indeed.

Oh, it's 61.5 ounces AUW.

A fast 1 meter glider with ailerons that is too heavy to be used for anything but a slope plane. I've thrown mine as a DLG to set it up and ended up hurting my shoulder trying to get descent altitude. The rudder broke too often on those fast landings. I replaced and beefed my rudder to be able to handle the landings, but had to add more weight to balance it. It is in the hangar waiting, months now, for an opportunity to fly at the slope.

I was thinking of throwing it off a hillside to slope it, but another possibility is to install the included hook and launch it off of a hi-start. Different slopes for different folks.

Update 10-27-2011: I just tried slope soaring for the first time with the Bobolink this past weekend. At 11.5 ounces it's fast and responsive, yet it would go up like a kite.

Before we left we had four out of four damaged planes. I was lucky. I only got a dinged leading edge when I got blasted up and back by the wind, about sixty feet, into the trees behind us. I was only about five feet off the ground trying to land when it happened. The speed of it all still amazes me. We were flying off a rocky beach on Long Island's north shore.

A great all around sailplane. I actually wore out the elevator hinge on mine. In all fairness, flying in cold air (when your fingers get numb) may have had something to do with it.

LISF ALES Builds This is the Long Island Silent Flyers (LISF) Altitude Limited Electric Soaring (ALES) Builds thread that I started. Others have contributed as well. It contains a lot of information about restoring Raidans (they all start coming apart with use) and modifying Radians for ALES contests. ALES contests have helped keep interests up and folks flying in the club when DLG and RES have fallen behind what they used to be.

This is a Chinese import that is made and flies well for its price. It used to be one of the sailplanes I flew and enjoyed the most until I hurt my shoulder throwing the Bobolink.

I chopped 6.3 inches off the rear of the tail boom to be able to balance this model with zero balance weights. That brought the tail close to the same length as similar sized DLG models flying at my field.

That blue foam in the tail is like a neon sign against a blue sky. It seems to get brighter the higher it goes.

I'm currently building a Bird Of Time for the Long Island Silent Fliers (LISF) one design build and contest. Every BOT being built for this contest is different. Mine has a four piece wing. I'm adding spoilers, carbon capped center spars and the capability to swap noses. Swap-able noses means I can decrease the AUW by using a longer nose with the balance weights further forward, use the original size nose for the One Design contest or use a nose with an electric motor built in.

It's been test flown, which is not to say that it's done. It went up in a strong thermal and it indicates lift well. That's all I can say for it. I'm making changes and will do some more tests flying to get a feel for handling.

It's been completed as part of a larger group build and contest. See the One Design build thread here.

Actually, it's a DL-50. This primitive editor doesn't always do what it should.

This model never launched as well as my Quick Flick IIs. It hooks a little on launch, while the QFs launch straight. It does better at catching thermals than the Quick Flicks and over time it's held together better, too.

I have three of these planes, all repaired and flyable now. I had a lot of fun with them during the summer. I needed three just to be able to keep two in the air. I removed and replaced the tail feathers more than a dozen times before settling on a method of hinging and mounting them that holds up and gives me good control.

I spent a good piece of my down time tweaking and trying to make these models fly alike. It never happened. One consistently launched straighter and higher than the others.

Update 10-27-2011: I gave away three of these planes. Two are being flown and one is waiting for a receiver. One of the pilots flying the Quick Flicks has gotten an Apollo and a Stobel, but hasn't flown them yet.

01-22-2011: I'm presently rebuilding an Airtronics Legend. This is a bird from the early nineties. The t-tail is what I really like about it.

I created a thread that shows the Legend being rebuilt. Old Legends Never Die

I got an unused, warp free Legend fuselage. I'm thinking of building as light a fuselage as I can. Then the bricks I have for wings need to be replaced.

Update 10-27-2011: I started a new thread: Building A Modern Legend. It was intended to be about making the Legend fly better, possibly by using a new modern wing. So far it just shows a new fuselage being used and the center wing being beefed up. A carbon pushrod and a pull-pull system replaces the plastic pushrods that I got it with. Now it flies much better, but it still needs to be lightened. All that's left is to rebuild the center wing. I could make it lighter and bigger, although if I want to keep it stock only lighter is an option....Continue Reading
