Title: Scrap built foamy tips Post by: chiefsrinc on April 27, 2013, 02:19:05 PM Just thought I'll put together some ideas I came up with while building a cheap, scrap built foamy good for newcomers. Basic plans are from http://www.fancyfoam.com/index.php?main_page=product_bundle_info&cPath=87&products_id=309.
Haven't flown it as yet but do not think it will be a problem. Some tips: Basic material: 4 mm foam board (sold here under Cosmic brand from Taiwan - have seen similar stuff in India) Glue used: Mostly different types of Fevicol Motor: Old Permax 400 from my Easystar (now converted to brushless). Held in place with scotch tape. 5x6 prop used. Servos: Again scavenged from old Piper Battery / ESC: New 7.4V, 1200C Durasky LIPO / New 30A brushed-LIPO/NiCD compatible, Chinese Control Push Rods: Kebab skewer sticks and bent paper clips Control horns: Cut plastic credit card Wheel axle: Metal hangar wire passed through cut ear bud stick. Wing spar: Chopstick Wheel: Caps from plastic gallon water bottles, glued together Control surface hinges: Scotch tape Used Mseal for insulation when I ran out of insulation tape. See pics of ESC - battery connector. To retain dihedral on wing tips (winglets), make groove and then stuff with Fevicol 5 min epoxy and hold in place Use Fevicol 5 min epoxy to strengthen weak areas |
