Geobat- Foamie RC Flying Saucer- With Plans
 
Foamie GeoBat RC Flying Saucer
Hello, for the last few years I have worked with Mr. Jack Jones of Newnan Georgia and Mr. Randy Pollard on the GeoBat project. Jack Holds a patent on the general wing planform of the GeoBat and has dedicated many years to the refinement of the design.

I came onboard when they needed a test pilot for a new 66” Diameter model with a Webra 1.20 engine. This was around 2005 I think. I was very impressed with the flight characteristics of this model and we still fly it to this day. It has had cameras and GPS’s strapped on….. Has been flown in extreme winds and heat. Had barbell weights added to the max.
It was featured on the discovery channel and aired world wide. It has incredible slow speed performance! Yet max speed of 104 MPH without retractable landing gear.

Some guy in California took the nitro set of plans and built a fan fold foamie using the general outline. Then a local guy and I set-out to make some foamie GeoBats.
I refined the drawing on AutoCAD and many have been built as of this writing.
(He later left the project)

The California guys put lights on them and started claiming they invented the whole deal.
They started selling RTF GeoBats for a grand each and not giving credit or royalties to the Inventor Jack Jones. But that’s a whole nother story.

These 36” foamie GeoBats get so much attention wherever they are flown. They are extremely stable no matter what anyone tells you about a round airplane. The stability is incredible, so much that they tend to not want to roll very fast.

With the modern LED lights available these days you can make an awesome night flyer with the GeoBat.

Keeping the plane perfectly round is trying at times but it is really part of the appeal of the machine. We know everyone wants to be a designer and know you will make changes. Just please give credit where credit is due and have fun.

Flying saucers are coming …. Believe it!
:eek:

All rights to this Design go to Jack Jones, Newnan GA. Please do not post CAD files here or start cutting and selling these without permision and royalty discusions

I have switched to using 6MM CF tubing for the main spar, also:
The CG should be shown 1" forward from where it is on here.

I prefer to build the GeoBat with Blue FFF.
otherwise 6mm Depron is excellent.

Thanks to Derek for tiling the plans! :D

EDIT: I added the 1 meter version (40 inches)

1st Cut out the 2 wing halves. Make a right and a left when using FFF so the surfaces will match.

This is still my favorite video GeoBat or otherwise!

GeoBat Golf Cart Flying (7 min 3 sec)


Not the greatest quality video, but a Nice flight with an E-flight 450 machine.
Pre-KFM airfoil

GeoBat Foamie Demo Flight (2 min 40 sec)


My first Hero HD video

GeoBat Surveillance (8 min 25 sec)


The is the blue GeoBat in the build pics
GEOBAT (4 min 9 sec)


Someone asked about the 4 aileron version.... this is the last GeoBat I built and the best flying. The roll rate is great with the 4 ailerons. They are set up mechanically with differential (More up than down)
Also in this video you can see a CF reinforcement in the fuselage instead of the spruce sticks.
Geobat with 4 ailerons set-up (1 min 10 sec)


This video is of the fighterBat above with the EDF unit on top. The 4 aileron set-up is a pain but it's cool as crap and it makes it roll really well. On the Nitro and gas UAV's we use these for flaps, but the foamies fly so slow we have not yet tried them as flaps... maybe soon!
Radio Control Foamie Geobat (1 min 10 sec)


Here I am flying the Pink camera ship. We do this is my back yard just for fun :D My son Josh is flying the slow stick. Lloyd Snyder is on the slow stick with Streamers.

The first half of this video is the Nitro 22lb GeoBat featured in the Discovery Channel Video...
The 2nd Half is my First Foamie GeoBat. It had elevons and a In-runner 370 with Gearbox. It was a great plane.

Sorry to hear that. I know how that works. Are you going to release plans for the rest of us to build from?

Side note: You still bringing your cart out to SEFF this year?
