New concept Delta-copter AP/AV heavy lifter

-adjustable tail rotor moment
-adjustable main lift motor incident vector
-3 axis dihedral design
-fix base tail rotor with rudder control

Strong nylon clamps secure three main motor mounts. There will be forth connection link through to the centre plate, which will allow for adjustable incidence of main lift motors. This tension will also increase strength by tensioning the truss.

The tail motor has been off set for torque roll and main lift motor a counter rotating. There should be very little force required to yaw the aircraft but that’s the theory

By adding dihedral or angling the prop into the center it will create a intersecting thrust vector, if the ship was to pitched or roll this trust vector will change in relation to G force the high prop will decrease lift component because the angle apposing gravity will increase. The low prop will experience the opposite effect, add all this with some gyro stab that the theory.

The dihedral in the Delta-copter is necessary to reduce the overall dimension of the aircraft. The vector angle will be adjustable and will allow for flight trimming. I hope to achieve inherent stability and reduce the overall width of the aircraft but still maintain manoeuvrability.

Here's some spec.

Are you going to build it Jerry?

Built, will test fly soon.

Should be very interesting. Keep us posted as to the results of your tests. Is this your own design Jerry?

Jerry from this development, do I sense a dissatisfaction with the previous 2 motor machine? I still can't find much about that design other then over inflated claims by the inventor.
Speaking of new items my new stabilization system came in on Friday. I got the FY-20A, 3 way stabilization gyro. You really should consider this for your new machine. It was tested on tricopters successfully and the FPV community likes it. It is super simple, does not use external sensors and seems to have little or no drift and 3 operation modes. I just plugged it in on easy star and with no adjustments it flew hands off, steady as a rock even with turbulence. But wind was not much this weekend, surprisingly. It is now on my Stryker to really test it's worth. I will do more testing this week but so far I am impressed. I tried the Fly mentor, which is a total crap and tried FMA copilot, on friends plane, that has too many wires and parts and adjustments and results were less then impressive. For AV this looks pretty good but time will tell.

Not at all the nVader is a great set up and plans are still moving FWD high level test will progress soon as I get the USB device I need to mix the roll gyro mixer. This is an improvement to it current operation. I do have some tweak on the Drawing board and will reveal them in time.

The Delta-Copter a design that I had in the back of my brain and I finally moved it to reality.

I am looking at the FY-20A it looks promising, let know you findings.

Here's what we learned:

-Original dimension was too narrow to hold roll stability
-Rudder control works but we tilt the tail motor to trim the rudder control neutral at up lift power.
-Dihedral is out for now we will bring it back after we have better flight stability

[tech1]

Just my 2 cents worth, but your nylon motor mounts look a little weak for the load you are supporting. These clamps can twist around the bar and my not supply the needed stability if the motor starts to vibrate or something is out of balance. Has this been a problem?

[eyeinsky]

Some more changes to the Delta-copter; rudder is out and vectoring tail in, also hard mounted the main lift motors to the tube frame.
