Also is there some wash-in or wash-out that can be added to the glider so that when I go for the first hard launch it won't dive bomb into the ground?
Thanks so much :DD
On a side-note how are you guys doing time-wise with your gliders? And like someone said include units/ceiling height/etc ^.^

Uh, you can help yourself out....ibetyoudonthave wrote:This event looks really fun! But I have noooo idea how to build this or test it!!!!!!!!!! CAN SOMEONE PLEASE HELP ME OUT!!!!!!!!!!
Seriously, with all due respect, what do you think might be buried in all the pages of this thread?? Information on how to do this event.
If you go to the first page, and read through, and think about what you read, and follow the numerous great links, I assure you, you will have a very good understanding of how to approach it, and what to do. You may well have, and develop from that study, some specific questions. As you will see, lots of folk have had such questions, and have gotten good answers.

Why? Are your wings breaking?science8 wrote:Quick question. Would it be worth covering my wooden wings with the carbon tape?
If they are breaking because of wing stresses, it may be beneficial to add cabon tape but only in the area required.
If not, the covering will only add weight.
As already mentioned, it depends. Though I can' think of many reasons covering the full wing would be worth the weight hit.science8 wrote:Quick question. Would it be worth covering my wooden wings with the carbon tape?
In addition to breaking issues already mentioned, there's another reason to add carbon selectively. That's to stiffen the wing. As you start to get the weights real low (2-3 gm) you may have trouble with the wings flexing too much on launch to control the trim. That's why you see small amounts of carbon fiber along the wings on some of the plans on the AMA site. The carbon is run down the top and bottom of the wing along the approx centerline to act as spars and stiffen the wing more than prevent breakage.
Another comment on reinforcement. The leading edges tend to get dinged as they are very thin. A common trick is to attach a small strip of srpuce or bass (say 1/16 or 1/32 square) to the leading edge before sanding to shape. Then most is sanded away. This leaves a thin strip of harder wood where the balsa would tend to ding most often. You could do the same with a carbon fiber too.
But be careful, a little goes a long way and weight is always your enemy.

Thanks for the info about the carbon fiber!
