its l about engine power pitches this is an atack heli so it needs to do a lot of stuf they made this one so it also can do loops its dangeraus and once in a stall always in a stal whit these things
ill try to help explain why the number of blades helps with cyclic.
simplified:
In a two blade system, when the blade is doing the action to push the nose down, it is only doing it in one part of its rotation, the rotor pushes the nose down for a wee bit and is then doing nothing until it gets back to that position,
in a 4 blade system, this, push pull motion happens twice as often.. ie, when a two blade systems rotors are only just becoming perpendicular to its body, the 4 blade system is already acting on the body.
I don't think there are any semi rigid two-blade heads. There are many two-blade model helicopters that perform aerobatics - fluid and gyroscopic dynamics don't favour size - QED! Spinning rotors act like a solid disc so the number of blades is irrelevant. However, a non rigid head (drag hinge, flapping hinge and droop stops etc) generates massive articulation forces as the blades try to flap to equality. The head can't restrain the disc dynamics causing blade flapping and fuselage strikes.
Semi-rigid 2 Blade OH58A/C Kiowa, AH-1 Cobra, TH67 Creek, just off the top of my head. I have no experience with model helicopters, but it does sound like you know what you are talking about.
I had no idea helicopters were able to do this! I was quite surprised

most helicopters dont have the power to withstand that

hab erst gelesen: tighter helicopter loop :D
war er aber auch ;)

It's too bad real helicopters can't sustain inverted hovers, cuz THAT would be impressive.

Mi-28 does the loop better. But Tiger is also good

No arguing here. Oh, and I probably should have added "4 or more blades and a fully articulated rotor system".

1. Are you a helicopter pilot?
2. Have you ever performed the maneuver?
If you answered no to these questions, then you have no credibility here.
patmagroin20 4 years ago
It looks nice, but pretty much any helicopter with 4 or more blades can pull a loop.

Rubbish - aerobatics in helicopters has everything to do with semi-rigid rotor heads and nothing to do with the number of blades.

Well, how many semi-rigid 2 bladed helicopters have you seen performing acrobatics? The answer would be "none". Mast bumping (bump) precludes it.
