How to... / Making a Sailplane/Glider, for my leaving cerftificate ?

« on: November 20, 2010, 18:39:57 PM »

if you want to build a free flight glider, look at the Lulu, which is relatively simple to build and a reasonable flyer.

A parts kit for the Lul is available form Belair:

and check this:

Free flight does need a BIG area, as once launched, the model is at the whim of the wind

Thanks for taking the time to post twice, billscottni. Your links and time are both apperciated greatly.

Hi CJ,

I would have  thought a free flight model would be easier and cheaper to build. (No radio control equipment to buy/fit.)

I’ve never been into free flight planes so I don’t have any info on them I’m afraid, other than to tell you that you launch them by hand and, provided it’s a calm day, they fly. (Sometimes a very long way! :shock: )  
 
But I’m sure other members of this forum would know of planes and costs………

Fred, Lez, Ralph, Gerry………Anyone?

Hi there happy days  . I was under the impression that a free flight model was the same as a hand launched glider, but i geuss that is what you geuss for doing you're research at half two in the morning. Your terminology gets all mixed up. So just to clarifyI want to build a free flight model. I'll just edit that line in the question. Thanks for your reply.

Hi, there, I am a 6th year student in Dublin and I have decided to do a bit of research into what I should do for my leaving certficate construction studies project. One of my ideas is to do a glider. Now I have no experience using or making one of these, so the purpose of this post is to find out some key issues. To determine if this is a realistic project for me to take on. Hopefully you can point me in the right direction to getting a very good mark on my project in a subject i hope to do more than well in . So if you could be so very helpfull as to answer these following questions. It would really make my life a whole lot easier.

#Questions.
1~I would like to make a simple Free flight model. What design would you reccommend for me ?
2~Where can I get detailed blueprints/insructions for this sailplane? To basis my working drawings off.
3~Where can I get the balsa wood for this project and other materials?
4~Do Ineed any specialist tools?
5~How much will the cost be approximately?
6~How many hours will I need to complete the project from start to finish?
7~Do you know of any books/websites/other sources that deal with the issues of glide ratio, resistance and other key issues that deal with glider flight, so I can justify my design in my brief.

If you could answer some or all of these questions that would be pretty sweet. Also if you think that this is to big a project for someone in 6th year to take on, just tell me. My second plane if just to make a stationary model of a bi-plane. Have always wanted a glider and tought what better excuse than to make one for my leaving certificate constructions tuides project.

Also just in dealing with question 1, here is some of the images that I have googled and looked simple to build.
