I don't know about the whole outdoor thing.
Coaxes don't handle wind well. I'd like to see more outdoor video. Not just a few secs worth.

Watch this video of the X350 5B1 flying FFF outdoors, notice the flags blowing in the background, pretty good performance and authority in wind. It's obvious how it is done, the 5th channel mixes the pitch with the main motors throttle, so like cheapo 3 channel helis, the tail rotor will pitch the airframe so that the main rotors lift are vectored forward and throttle is applied for forward or rearward thrust,

For the price no thanks.
A four channel does the same with a swash instead of a tail rotor.
Any fixed pitch heli will not handle much wind.

That is a pretty narrow view on things?

Both of those have swash plates, not relying on only changing rotor speeds for control.

Looks like that config would reduce or eliminate blade strike issues requiring one or two less mods. Still wondering if a BNF Eflite CX120 at 129 and 70.00 worth of parts would get me further than this 199.00 coax.

No, because you still have the same problem, cyclic alone with any helicopter doesn't provide enough percentage fwd/rwd thrust of the total lift from the main rotors, this includes single rotor fixed pitch and CP setups, to be able to fly effectively into wind, you must have adequate fwd/rwd thrust. the problem with conventional helicopter designs, the percentage of thrust vectored away from the primary lift thrust to just keep the VTOL aircraft aloft by cyclic pitch is just not enough to really yield adequate longitudinal velocity to overcome the prevailing head/tail wind speed with any authority.

In that video it did not look like the heli had any problem in the wind.

In the case of the RCINTHEBOX 450 size heli, the prop in the back is pushing the heli in FFF. In the case of this X350, the prop is pointing up, just like on 3 channel heli's. If it's pointing straight up and does not pivot, what exactly is that thing doing? That heli, in FFF, looks like any other heli with forward bias from shifted CG. Most of us aren't into 3 channel heli's, so, we don't know about the rear motor and prop.

Extreme Flyers X350 5A2, 5 CH Coaxial, flies in wind/Fast forward Flight capable.

X-350 5A2 now in stock at Hobby People






It's on it's way, ordered today with Hobby People.net Free shipping promotion,

Free shipping is good from 12/7 thru 12/11



anxious to try it out, I am a half mile from the Pacific ocean, and rarely is there a breeze less then 5 mph anytime, typical wind speed here is 8-10 mph. X-350 is rated for 8 mph wind. It would be nice to have a large heli like this that can be flown in my fairly small yards in normal wind conditions. Will post my impressions, pics and flight report upon receipt.
