Title: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: topalle on April 25, 2014, 04:12:56 PM Hi Everyone,
This is my second model for RC India Sweepstakes. As the name suggests it will be a slow model, a lazy one. :giggle: Also the name suggests that this build is going to be a lazy (read slow) one. This is a Stick model. Wings are made of coro. Stick is a wooden beading. I have made the wing today after working from this afternoon. ( RIP our college P.R.O Sai Babu Sir). I'll post pics in a Minute. Regards, Topalle Srinivas Azad Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: topalle on April 25, 2014, 04:32:38 PM I was a bit late due to a short power failure.
Here are the pics Horizontal and vertical stabs yet to be done. Temporarily joined the wing and the stick with rubber bands. Later I will use zipties. Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: K K Iyer on April 26, 2014, 12:05:03 AM @topalle
You know you can do better than this! Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: topalle on April 26, 2014, 06:16:38 PM I didn't understand...
Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: topalle on April 27, 2014, 03:44:00 PM Tried searching for zipties... All sell packs of 150-250. not even 50-100...Tried sticking but the glue simply cannot handle the weight...

Srinivas Yesterday you said 1:1. Now 1:2, 1:3 A tennis ball can do better than that. 1:1 means if you hand launch it from 5ft height, it flies 5 ft forward. 1:3 means it goes 15 ft. See if you can get 50 ft from a 5 ft launch. It is possible with a chuck glider. Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: topalle on May 01, 2014, 06:03:42 PM I was standing and threw it with a barely needed force... It went nearly 15-20 feet
I am 5 feet 6 inches and growing... :D If I thow it with full force yes maybe it can go that far... Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: sanjayrai55 on May 02, 2014, 06:58:45 AM Maybe you wait for a couple of years till you grow more, and then launch it with ''full force'' :rofl: :rofl:

Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: topalle on May 02, 2014, 06:32:08 PM Can a catapult be made to launch this farther and higher?
Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: sanjayrai55 on May 02, 2014, 07:48:33 PM Use your schoolboy physics. At the instant of launch there is a very high velocity. Can this kind of model handle it?
Catapult is normally restricted to small jet type models - for a reason. Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: sanjayrai55 on May 02, 2014, 07:49:00 PM However, tow-line launches will work
Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: topalle on May 03, 2014, 04:25:45 PM I was in a fix whether to use a catapult or a slingshot...
Slingsot physics is too easy... but to calculate whether the model will be able to tolerate it is difficult. Towline will do then ok... Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: topalle on May 12, 2014, 06:35:24 PM Yesterday, I tested my model... It didn't fly very well... It was too tail heavy. I need to add a nose weight.
Title: Re: My new SPAD- The Lazy bird for RC India Sweepstakes 2nd model Post by: sanjayrai55 on May 13, 2014, 06:45:16 AM Adding nose weight should be your last option. First try to see if you can shave of some weight from the rear, and move the wing back. If RC, then move the battery front
