Prerotator

[quadrirotor]

What can we expect from this prerotator?

Thrilling!
i wouldn't apply it to mine even it's insured. :eek:
And i think the gizmo (a real genius i mean) could be mended a bit to get rid off any risk from rotor enlaced.
Or,am i a bit too over-sensitive?
best wishes.

Think I'd be more paranoid about the muffler that close to the plastic gas tank!

I'd also be concerned with the thrustline passing through my head...

I wonder why the engine is angled up?

andre, thats exactly like the one a saw recently, a guepard, the prerotator is a bit lazy, took a little time to prerotate, it s the basic system not the more efficient. a agree with others, this guy is mad to let the mufler so close to the tank, i v seen 2 of that model far better built.

Hi,all.
i have a simple question.i am always confused far as my mind on prerotation issue.i just wonder how gyroers choose their system,either electronic motor or flexible shaft. i need your help and hope that the answers might be useful to newbes like me. There must be something in between,and here it goes as below:

1\The power transmitted to the rotor head.Which is greater(flexible shaft,maybe?But we have fearsome starters).
2\The weights of the two systems.Is it that the lightest one be chosen under the same power transmitting?
3\Complexity.Motor seems neat and simple.But we see so many complex flexible shaft system applied in a common sense airborne people like simplicity which means reliability and low maintenance work load.
4\Are the two systems attached(in touch to) the rotor head during the whole flight, even they are stopped transmitting power before the take-off run?
5\Basic rule to choose a right one?

i know it's simple to you but it haunted me every now and then.

thanks.L Tim.

Possibly, a good slap upside the head when the belt broke. :eek:
