83" flying wing Mothership! 100% EPP, thermals, Aerial Photo

Up for sale is my huge flywing wing, the Mothership.

83" span (measures 82.5")

Mothership thread: http://www.rcgroups.com/forums/showthread.php?t=884646

Breaks down into 3 pieces (I modified the kit to do this), each panel is equal in length, about 28", so all three pieces will fit into a box that is 32" wide x 28" wide x 12" thick

I used this wing for Aerial photography (see photos). I can include the foam chunk I used to hold the camera, if you want it. It has a GWS servo attached.

The cheapest shipping is Fedex Ground, and they want $42 to ship this thing. (UPS wants over $60, and USPS wants over $120).


**** Sale pending, status will be updated Thurs 02/26/2009 *****
**** subscribe to this thread if you are intersted in purchasing, and want to be notified if it becomes available again this Thursday********


Asking $220, shipped to CONUS. AK, HI, and Canada pm me and we can work something out.

I no longer have the camera showin in the photos below (it was a cheapie), but for an additional $20, I can include a Canon PowerShot A540 that has a non-working flash, but works fine otherwise. It does not fit the camera pod, but the pod is easy to modify.

Specs:
Wing uses two carbon tubes per wing. Metal rods were fabbed with stops, to insert into the carbon tubes at the joints. I then used clear packing tape to hold the panels together. This worked great and there were no flapping or flexing issues.

I attached a "pod" of EPP to the bottom with a lexan sheet for a skid plate. The pod allows me to easily hand launch this large plane by myself. It gives e something to grab. It also protects the bottom of the wing during landings.

Motor
Hyperion HP-Z3025-12 outrunner, designed for lage folding props and 4S lipoly. http://www.aircraft-world.com/prod_d.../z3025spec.htm

Prop
Aero Naut 13" folder included with folding hub. i will throw in the spare hub I have.

This combo pulled around 30 to 40 amps

ESC:
Castle Pheonix 45 programmed for Lipoly.

There is a separate Battery Eliminator Circuit in this wing, as the largish servos draw too many amps for the built in BEC in the Pheonix.


Hitec 8 channel receiver. Lots of room to trigger the camera from the transmitter.

Hitec HA-225MG servos mounted in the outer panels. The servo horn screw faces the root of the wing, so a screwdriver has to reach in only 1/2 inch to make servo horn changes easy, without removing the servo from the wing. Nyrods were used for pushrods.

I built the plane very light so that it would fly slow and make a good AP platform. Since its so light, it is a thermalling monster.

I used two 4s lipoly in parallel (4s2p), at 2500 mah each, for a total of 5000 mah. This allowed me a run time of 20 minutes or longer if I shut down power to glide. The prop folded, allowing it to glide easier.


Please note:

The covering on this plane is not perfect, and has small punctures on the bottom side that were caused by weeds poking the plane. There are only a few of these, and could easily be patched. If you need some additiional covering, I can throw some in, if I can find any left over. I used a special, super light version of a iron-on covering on the bottom of the wing. The top is packing tape as is traditionally used on Zagi type wings. I will throw in whatever colors I still have left that match this plane (3 or 4 colors on the top side).

FREEBIES! (that go with this plane only!)

Camera Pod with shutter servo

New in package 15 x 9.5 Aero Naut folding carbon prop (not recommended for this motor, was used with prior motor)

New in package 13.5 x 7 carbon Aero Naut folding carbon prop

used 15 x 9.5 carbon Aero Naut (not recommended)

new out of package Aero Naut CAM carbon 13 x 6.5 I have not tried this prop. May give more speed, due to pitch, but not thrust (diameter is the same as the current 13" prop that is on the plane.

new in package Graupner CAM 13" x 7" folding carbon prop

new in package aluminum folding prop hub with spinner. Spinner cannot be used in a pusher application. I just used the hub. This NIP is a spare.

Selling this plane to fund my car project (see my sig)


I am 6 feet tall, and weigh around 200 lbs.
