ok. so i tried to make this helicopter when i was like 13 years old. i used huge ass motors to drive the rotors and that made it a tad heavy hence unable to fly. i counteracted the spin with not a tail rotor but a second main rotor like that of the ch47. i was thinking that would increase the power but with the horrible power to weight ratio, i think that just increased the supposed helicopter’s love for the ground. so you know, the rotor blades were made with very light plastic (that transparent plastic that toys are packaged in) inclined to around 40 degrees. the plastic, i presumed, could in no way withstand the weight of the motor but i assumed that the centrifugal force on it would keep it straight. i am still not sure if it would have because as it is apparent, the helicopter never flew. so there were 3 rotor blades on each shaft. i still wonder which is more efficient. more rotors and little angles or less rotors and greater angles. ok. so my cousin just got this rc helicopter with a tiny powerful motor driving two huge rotor-blades with adjustable angles from like 45 degrees to like 10 degrees, a tiny tail rotor to counteract the spin, a battery that i have not seen but am sure is ultralight and it has this ingenious gyro on the top. i am tempted rip that motor out of that tiny little helicopter and use it for my own but even if i do, i will have to get a second motor because i have no way to produce gears to make the tail rotors move proportionally to the main rotor to make the same motor drive the main rotor and the second one or tail rotor. gosh. i am 16 for Christ sakes. anywhoo, i’m about to resume the project i started 3 years ago and i need some major new knowledge or else, i will FAIL as i always have. that helicopter must fly whether it likes it or not.
