![]() ![]() ![]() I’ve watched a bunch of Josh’s free flight / rubber videos. There’s a lot of tuning dedication, and at 30-40 minutes per flight… And then he designs the propeller so that it puts out the longest duration of just exactly the thrust needed to spiral up to the top of the space he’s got to fly in - and this may be the ultimate constraint. Josh uses specific rubber that unloads slowly and consistently. (The dobs of hot glue in the OP video weigh as much as Josh’s entire plane…)Īnd then tuned. Everything is optimized to the tenth of a gram. The covering is many times thinner (and lighter) than cling film. The wings of these serious planes are made by pouring a thin film on water and pulling it off with a frame. Would you believe: I think the duration record is around 60 minutes?īut this isn’t assembled with random rubber and dollar-tree foam board, as you can see. Posted in Transportation Hacks Tagged aircraft, free flight, radio controlled, rubber band Post navigation Sounds like fun!Īside from powering world record attempting radio controlled aircraft, did you know that you can build a rubber band powered refrigerator? It’s true! What will he do? Check the video, too, for ’s challenge to the community to join him in trying to beat the world record. His personal goal of a 12 second flight was exceeded, and then Guinness called! They’re interested in certifying his attempt as long as his plane can fly for at least 30 seconds- almost double his current ability. did more testing, more problem solving, and through rapid iterations, he eventually was able to have a successful flight under radio control. Eventually a slightly heavy but solid solution was found. Since there were now eight rubber band motors, a mechanism was created to release the propellers in sync, but this was problematic. Starting with a successful free flight aircraft made of foam board, simply scaled it up to an eleven foot wing- one foot larger than the ten foot world record holder. Rubber Band Powered Free Flight c1915 By Unknown author – With a 10 foot model taking the current world record, as you can see in the video below the break decided to see if he could beat it. By winding a rubber band, it could store enough energy to turn a propeller for a short duration. One technology that really took off was that of rubber band power. Why rubber band power?īefore little two stroke motors became affordable, and long before electric motors and batteries were remotely possible, there weren’t a lot of options for powering your model aircraft. Egged on by adoring fans who demanded more aircraft videos, has decided to break the world record for rubber band powered aircraft… despite having never built a rubber band powered aircraft. ![]()
