This isnt RC. but i thought i would put this in here.
These are pictures of my rubber band plane for science olympiad. The rules specify the maximum dimensions that the wing, stabilizer and propellor can be as well as plane weight and rubber band weight. I use a 3/32" 2 gram loop of rubber band. its about a foot long and i wind it up to around 2000 winds using a 16 to 1 winder. The objective is to get the plane to fly as long as possible in a certain space(usually a gym). because after it starts flying its going by itself i built it with left turn in it and it just goes in circles. my best time this year in our school gym( around 30 feet high) is 2 minutes 30 seconds. I just decided to take pictures because im about to perform some liposuction on it. lol its overweight and i gotta get it down.
here are the pictures.





I guess you could you call this a hobby. its a love hate thing. its a lot of fun when the planes work, but its complete agony when they dont.
the best time ive ever gotten was 4 minutes, but that was with a bigger plane. i hope u guys enjoy...
