QuadYcopter Maiden Flight video
There's a few different names that might be applicable like a Y4, Inverted V-Tail, Y-Copter but I think I'll call it the QuadYcopter and it flies! All I had to do before this video was reverse the direction of two motors and it flew better than expected considering the lengths and angles are all eyeball precision.
I expect the QuadYcopter should deliver the best aspects of Quads and Tris;
- No mechanical tilt needed on the rear motor (tri negative)
- Larger unobstructed field of view looking forward (tri positive)
- Non symmetrical airframe which should be easier for orientation at long distance (Quad negative)
Notice in the video, it's quite twitchy in pitch. I reckon that's related to the CoG which I've moved forward by mounting the battery all the way forward. This isn't a big problem as I'll probably mount a GoPro up front which will further help with balance. The underside mounting for the battery means it can be moved all the way from the rear to the front to compensate for camera / cameraless flight.
I still need to mount a low voltage buzzer on the airframe. The problem is, I've started using an 1800mAh 4S battery whereas most of my other batteries are 3S. I've had to order a couple of voltage 2S-8S detectors that let the voltage be set via a jumper so I can fly with either 3S or 4S
