Delta Vee - Flying Wing with No Movable Control Surfaces
 
Quick video of my Delta Vee, a Bluecor Delta Flying Wing with no movable control surfaces...all done via motor vectoring.

Sweet Jimsky! Cant wait to see the flight vids!!!

Looks good

ummm

what happens if ya loose motor, no way at all to control the glide :)

Good point, but it's only Bluecor and a couple of cheap motors and ESC's...just wanted to see if it can be done. Heli's don't glide very well either.

Full speed ahead! :D :D :D

Finally did the maiden flight today. I had Tom Hunt (Mr. Electric) be my test pilot.

Took off without a hitch, Tom trimed it out (lost the reflex) and did a few circuits. He felt it didn't have enought throws (I had reduced them from what was shown in the video), so he landed (story in itself) and I bumped them up.

Second launch was fine, much better. Tom was amazed how stable the plane was. He tried a roll and it was like trying to get a supertanker to make a U turn. Tom was unable to explain why this was so. He eventually gave me the radio for a try.

Flies like a trainer...flat and level, amazingly stable. Turns are slow to initilize but eventually they catch, and track right through. So much for this rolling like a drill.

Tooled around some more and decided to bring her in. I lined her up to land, floats quite well for a flat plate airframe. I chopped the throttle and Tom shouted "NO!" and it took a moment to realized my mistake. Zero control surfaces means zero control when gliding with the motor off. The plane started to veer to the right and after I realized the right stick was doing nothing to fix it... I wacked open the throttle. It nose up, stalled and dropped in...breaking a servo arm on the right motor.

So it did work and it did fly....that's all I was looking for. How to land, well I got to work on that. Like I said, it's cheap winter build fun using Bluecor and Hobby City motors, ESC's and servos.

It will be back!

Are u going to add control surfaces? .. or just a rudder.

#7 jimsky Jan 26, 2010 05:57 PM

I think a rudder is the simplest route...
