Title: My First Scratch Build Post by: kumardasai on November 12, 2012, 05:20:59 PM Hi
This is my second scratch build model (First one didn't fly properly), made with coro wing and foam fuse, It has only Elevator and Rudder (No Ailerons) with below specifications...Its giving around 13 mins of flight time. I will share the build pics soon. My Sincere Thanks to Anwar-ul-huq sir for giving me this Knowledge and Thanks to Pradeep Sir for giving me the foam sheet (This foam sheet is very strong and light weight, it has survived for somany hard landings). Wing Length : 1000 mm Fuse Width : 750 mm Motor : E-MAX CF 2822 ESC : 30 amps Battery : 3S 2200mah http://www.youtube.com/watch?v=yn5C0Xfr720 http://www.youtube.com/watch?v=1yXVNkLZvNA Title: Re: My First Scratch Build Post by: arun.sreelakam on November 12, 2012, 09:33:27 PM nice one dude... try to upload more close up photos... :)

Title: Re: My First Scratch Build Post by: kumardasai on November 14, 2012, 12:51:48 PM Yes, Its weighing around 500 grams (The complete Model with receiver). That might be one of the reason for less fly time and i also doubt on my battery, i will change my battery and will test it again and will let you know the exact results soon. And one more thing is, I am not continuously flying for 13 mins. I fly for 5 mins and land the model, and so on.. (I am Practicing landings, you can clearly see the landing of my model in the second video).
When i was building my model, i was not very sure, if it fly or not, thats one of the reason, i have not captured all the build pics, But i have very less pics, will share for sure soon. Because my first model was a big failure. I was really happy to see my second model was successfully flying and i am learning the flying.

Title: Re: My First Scratch Build Post by: kumardasai on May 20, 2013, 01:23:45 PM Thank you for your compliments @ Kamaraj Sir, VC Sir and Ved...
The material i used for the fuselage is foam (Bore Coated Phenolic Foam). This foam is used for Air Conditioner insulation purpose. One of our senior Aero Modeller Mr.Pradeep Sir is having few sheets of these foam. I have taken a sheet from him. This foam is light weight and enough strong. The fuselage is in rectangle shape with 750 mm length (Attached drawing image). I have not even sanded the corners of the fuselage and used it as it is. Made 2 small cuts in one end of the rectangle for the elevator and rudder. And the other side motor is attached on a plywood. Coming to wing, wing is made up of coro sheet with the length of 1000cm and sticked with a 8mm carbon fiber tube (1000cm) for strength. Wing width is 20cm. At the edges for di hedral shape i have used cycle spokes. No Ailerons. I will post clear picture of the wing today night. Let me know, if you need any other details. |
