The Hunter-Vtail 500mm frame, available from QcRc.ca, is constructed in black G10 and uses aluminum standoffs. It uses an unusual arrangement of motors, with which "the yaw autority is not only managed by the torque of the motors, back motor are producing a vector of thrust that push the tail of the copter one side or another, so it move really fast. Another great thing is, the center frame go way in the front allowing you to place a camera to fly FPV or film a HD image ( such Gopro camera ) that will not see propeller !" [sic]
It should be noted that the vendor recommends the use of the Rushduino Flight Control board, and this frame and configuration has not been tested with APM yet.
Selling at $95 Canadian, maybe some members would consider buying some of these for a developer or two who might consider spending some time working out APM support for this frame? Any volunteers for either role (donating frames, coding/testing APM support?)

I think that's a great looking frame, and seems to fly pretty well. I also really like the POV for a camera. The only way it could be better is if there was an integrated camera mount/gimbal. I'd seen one a while ago where they built a pitch gimbal right into the front of the frame.
I'll do the program if somebody wants to send me a setup.
My friend's use KKplus controller board everything works nicely ......
That does look like a nice frame. Deff on my shopping list :)
I've done a code changes for this frame but don't have the frame to test.
From what I understand the changes is not much, its almost like a X quadcopter, differences are:
1. Front motors no longer involved in yaw movement
2. Back left motor will rotate the copter in CCW direction (reversed) using thrust and not torque and Back right motor will rotate the copter in CW direction.
I'll post the codes and propose the changes to dev team when I'm able to test it.
Very good yaw response. Poor efficiency.
It's all just vectors and forces. Work out the math and do the motor controller. Way cool.
So other than looking bad ass what would the benifits be? Just the Video LOS?
I'm thinking the Vtail allows for a sort of Tri-Config/balance?
I am curious if a mixer between the rear motor and servo, of a tri, to the two motors of this V would be possible...
Talking myself through it:
Using a basic vtail mixer with a TRI copter config, motor 3 and with servo
Inputs:
Motor signal = elevator
Servo = rudder
Outputs: Left & Right of the V = Left and Right motors.
I've convinced myself its worth a try, On the "list" now
