Very Nice Paulice

My contribution and my favourite. Love it when he flicks the switch to hyper mode at 4:10!

'Twas about to post that vid- nice one!

Combo of 1400rpm idle1 and kickass 1900rpm idle2.... stunning machine, awesome flying.

Ha Ha, yeah Steve its a good one! Vid time 8:03! Simply amazing!

I pleased that this thread made me go read up on this heli..

For the same flight condition, “hovering on the spot” you need with 1300 rpm head speed about 570W while at 1850 rpm 1000W already required. With over 2100rpm it’s already 1500W required, almost triple the amount, although it does nothing more than float.

..for the excercise I took a 700watt draw for happy gentle flying and 2x5000mah 6S packs... theorteically you get almost 14 minutes... cut that to the 20% rule and allow for losses and you can still be talking 10mins for sunday sports flying on a pack pair...

They claim you could not do that with a flybar but I tend to think you can with the right combination of length and paddles but it's a moot point really.

There was a video on here a while back of the 3D Rigid doing all sorts of aerobatic moves very ably at something like 1200/1300 rpm headspeed.

..tend to agree..once you drop the headspeed you'ld drop the paddle drag too but you'ld lose some of the ranges and smoothness of fbl and get the pitchyness back plus the longer mainshaft, inherent slop with extra linkages...

Yeah, I know what he's saying from a design point of view in that the distance from the top bearing to the headblock can be shorter etc. but I think technically it's possible to have similar performance with a flybar. In other words, just because you drop the headspeed down I don't think it somehow goes below some threshold of where a flybar will function and maybe that's not even what he meant to imply.

But it's a moot point because the flybarless system gives the best of both worlds, the stability and still allowing the snappy response and without the worry of what happens between a hover and FF flight, etc.
