Really needing a break I spent a little 'me time' in the workshop messing around with old scrappy parts and stuck this thing together :) It's using on of our older QU4D airframes with off cut tubes, old motors mounts and a set op serious MT3515 T-Motors used on our older octos + a MT2814 with a 9" prop for 'WARP DRIVE' forward propultion ;)
It flies fairly well and will go shoot a test flight and see what warp drive speeds we can hit, thanks caption Sulu!
lets see if I can prop hower it! lol

Noticed a spelling error... Think you meant to say "Warp Drive - Monster Quad"
:p
Gary, it was interesting to test this. When sticking it together I realised the impact the horizontal force would have on the drone, mounting the motor underneath the motor pitches the drone up and the quad simply tries to level out, the drone in fact does not move forward at all as the pitching back is obviously fighting the forward movement, I then stuck the prop at the top thinking the force would pith it drone forward which it does and the quad moved forward pretty well (fast) the trouble we had was when turning, again a drone uses pitch roll to man over having a force constantly pitch the drone forward did not go so well when trying to bank, haha we had a short flight forward and then trying to bank left the copter kinda went crazy and It got into a OOD (oscillation of death) lol and went down hard on a solid concrete path ( like the only 4×4m block in a huge open field lol) and that was the end.
I'm keen to work on some new 'propulsion' drive quads;)
Thats a really cool concept and implementation.
I tried something in the same vein here:

I was actually pretty successful as far as I went at the time, but there is a problem.
For me (and my freind Oliver who did something very similar) at least we found that alignment of the horizontal prop with the vertical center of gravity was crucial (mine is pretty close).
The reason is that if the horizontal prop is offset above or below the CG it imparts a force that tries to pitch the Copter down or up / depending.
You might think that would be a small force, but that was not our finding.
Mine worked well because it is nearly aligned with the CG but Olivers was a couple of inches off and hardly worked at all (and he was using a much bigger motor.
The reason was that the more thrust the horizontal motor applied the more thrust the copter motors put out trying to compensate for the induced pitch.
Basically it turned in to a power wasting fan.
His copter did move forward, but not nearly as quickly as the amount of power being consumed in comparison to mine.
It also looks like it helps if the center of thrust is nearly lined up with the CG (vertically).
You have a novel prop arrangement and maybe that will help, but I expect you will encounter the same limitation we did.
And in response to Mohammed, no, not actually, don't need to change the code, you just hook up the horizontal motor to a spare receiver channel and tie that channel to one of the analog dials on your transmitter and then fly in Stabilize.
Nice idea, would need some modifications to the code to work ?
Like to see a video of this Quad flying and also interested if your using a APM and how you set it up
But interesting Idea :-)
