These are wing mounting bands or rubber motors? Title: Re: contest rubber bands india/bangalore? Post by: SI74 on July 21, 2015, 11:21:07 PM @ Iyer sir, these bands are not that strong; so I think it is motor. And 8" long.
Title: Re: contest rubber bands india/bangalore? Post by: maheshv on July 22, 2015, 08:53:51 AM I tried the rubber bands from rcbazaar. the 2mm ones broke before 200 turns and the 4mm ones are too thick to go beyond 150 or 175 turns.
Or am I doing something wrong? Lubricated the bands in castor oil before use. Title: Re: contest rubber bands india/bangalore? Post by: SI74 on July 23, 2015, 01:34:34 PM Try tying two bands together before winding to 250.
Title: Re: contest rubber bands india/bangalore? Post by: maheshv on July 23, 2015, 01:37:08 PM ^^. You mean parallel (to make it thicker) or linearly in a rubber band loop?
The latter has to have a longer fuselage and a bigger nose drop so that the centre of the rubber band (where the knot is) does not scratch with the wood fuselage causing friction. Have tried that before as well. :headscratch: Title: Re: contest rubber bands india/bangalore? Post by: SI74 on July 23, 2015, 02:54:03 PM Yes,linear. But I added one usual semitransparent rubber band as well to boost power.

Post by: SI74 on July 26, 2015, 10:57:09 PM I used 48 cm balsa wood fuselage ; Tourniquet split to 2mm thickness 50 cm long mixed with usual 4" rubber bands 6 nos ; and I could go easily upto 600 turns ( stretched it while winding still attached to prop) and gives decent flight time. Wings 60 cm span ( styroform plate) ; attached to fuselage using light weight packing foam
