It has the wren 44 turbine / SK 360 FC with a Spartan 670 tail gyro ,, BLS251 futaba DS tail servo, and JR DS 8717's cyclic .
Low hours ( 10 hrs) It really flies great ..and the sound of a turbine is just awesome .
It has only been flown normal type helicopter flight - no crashes .I really hate to sell it but life is getting in the road right now , so I would rather it go to a new home where it gets a chance to get off the shelf .

I need to get 4850.00 plus shipping on this ... don't really need to sell ,,but hate not being able to find enough time /energy to fly it .
Will be some what broke down to save on shipping as it is big ....Continue Reading

Here is the magazine article and a video in the video area .

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 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 .
