Notice the big scoop (marked in pink on the first page ) that goes down into the fan blast to bleed roll control air off to the wingtips.

Here is a BNF bird that I need to sell .
It is a Guai 200 Hughes 300 scale bird ,with a 3 bladed head and a sk 360 rotor head gyro that I was going to list .
It comes with micro 2.4 RX ,GWS gyro /hitec 55 tail servo ,3- futaba 3110 and is BNF ready .

Also have a few nip and used parts (two blade flybared head , etc. ) for it that will be included .

Will include 2- TP 3s batteries (1- 910 MAH and 1- 730 MAH )

Would like to get 450.00 out of it and a painted AS 350 fuse ,,picture of it found at bottom of my blog .

Here are a few gyros that I tested for use on VTOL's
#1 ACT Europe heading hold gyro for airplanes
#2Futaba 240
#3 Futaba 401
#4Revolution PZ 200
#5 Spartan 360

Notice the futabas don't move to far back and forth,, and are sensitve (jerk around a lot )

The ACT don't move as much as the pz 200 (and this might be due to the fact ,,it can learn the atv limits and I might have it limited right now on one side )but it is smooth through the range and follows good and is the one I have used on my V-22 so far

The spartan surprised me as it did pretty good .... good range and smooth ,but lagged some trying to following my hand .

But all in all I think the pz 200 had the biggest arc of movement and followed my hand movement the best . Which is what you need to control VTOL's with vanes and motor contorls that lag and need a lot of control movement to over come the movement that the bird is doing .

Link to video page post to veiw the vids.

Hope this helps you VTOL guys some .
