VTOL XVF-12A Rc version
Just thought of how my tri-copter would look with smoother exit port nozzle.So here's my idea. note: They are smoother on the inside.I'll post a photo of one completed pod once I get everything together.I'm looking for the right ball joint fittings for the servo control arms that move the nozzle.They will connect at the opening area of the nozzle. Two servos are needed to acheive a collective pitch type effect .I figure I could hook both front pods up to this system.I 'm looking in to the possiblity of connecting the tail pod to this system as well to have all three simultaneously pitch during hover mode.

This is a tri-copter kit made with carbon rod and Depron foam.For avid tri-copter enthusiasts.Just add:3 servos, motors,props, heading and rate gyros,speed controllers,battery,and reciever( 4ch).The prop guards(wire mesh) tilt via servo, NOT the motors or the props.6 ch set up is optional if you want rudder and elevators(for stunt flying).Anyone interested in building one?
The prop guard is spherical.The ducted props inside tilt on a gimbal for multidirectional control.The prop guards are thru-hull set up.Cavities in the hull provide a space for the prop guards. The kite has a "sock" filled with He.
I am starting to build.So far I have these parts (2) sphere halves(1) motor mount(1)motor,(1) propeller(1) propguard. Heres a photo. One half of the sphere moves the other half does'nt.The half that moves is designed to be controlled by servo to rotate 180 degrees,and it has the exit port for airflow out.The entire sphere, once it's put together, can be mounted on a gimbal so that the entire sphere can be slightly moved left or right by 12 degrees also.This whole assembly(there will be two of these on either side of the craft @c.g.) fits in a cavity in the hull or wing of a blimp type craft shaped like a manta ray. That's my story and I'm sticking to it. Any Questions?
This carbon rod and ripstop fabric ball is hollow and it has two halves that play different roles. one half houses a prop and motor.it does'nt move and it's entry port is facing forward as much as possible. the other half rotates 180 degrees.Inside the rotating sphere half is a separation wall that keeps air flowing one way (it's made of fabric also)...that would be OUT.hopefully.I'm trying to figure out how to connect these halves and get good movement without letting any air escape. Should they connect on a track and groove with plastic ball bearings or something else? Anyone got any suggestions for this crazy old man.?
This is my attempt to research how to make a spherical prop guard that can be rotated on a gimbal to vector thrust.How would I hook up servos to it? What kind of gimbal should it be mounted in?How light should it be?What kind of props should go inside the spherical prop guard?How much clearance from the inside wall of the guard should the propeller have?How many of these doohickys would it take to lift and steer a blimp? .What should the prop guard look like ?Should it look like a round birdcage?Would it work if it's structural design was similar to a round birdcage?Ever notice how much WIND a big bird in a cage can deliver when he's really flappin those wings?
