to bulky, i think the guys had the right idea by keeping is small…well sorta. i think the idea is to build something that you could stand up with and support yourself. it’s got to be under 100 lbs for the guys i work with!

i would love to see the plans and parts list for that!!!

the reason for the restriction with the pully system is because few engines can turn something as fast as they turn, even the car you drive doesn’t turn the tires at the same rate as the rpm of the engine, not even in top gear.

i don’t think model engines will produce the power for the thrust needed for vertical lift of a 200lb person + equipment.

wish i would have read your post, i looked at that angle too! but i also had the thought to use a different prop

yes and no, 2 engines under or over the props would have restricted air movement, and would have added more weight to creat the same power. belts are light and power efficient, more so then any other option i can think of. also you need the engine on your back to act as a weight along with your legs, that should help to keep you upright. i don’t think that it should have been extended down as far as they had it due to the fact that you will indeed have your legs under you provided you do have legs. the only thing i would have tried to do differently is adjust the pully system so give the props more rotation and increase thrust. also i would have tried using a 4 blade prop over the 2 blade prob provided the engine had enough power to turn it. in the episode the engine seemed to be turning at max rpm’s but did they really use all the power that the engine was capible of putting out? that is my question. i find that on the show the Mythbusters team does not always look at every variable. maybe they just don’t always see EVERYTHING at all angles as i’m sure it’s hard to do, but if they’re lookin for a new member for the team, i would like to try out for it! lol

Does anyone know where I can get a pyramid kit for my science fair project?
