In the aftermath of building and flying the Feather Shooter catapult glider I had an idea to try and make an RC glider that I could have just as much fun with.

This design is very loosely based on plans for a 36" span glider called Apogee by Mark Drela. I simplified the wing and took out the graceful curved leading edge. I built the fuse from blue foam insulation (I am HOOKED on blue foam now). The boom is carbon fiber.

This photo shows how it looked after the first test flights. Some wing straightening now had been done and I am reworking the fuse for better balance, will probably shorten the distance from LE wing to LE stab to help balance without extra nose weight.

I drew up a plan for this latest version, you can download it here.

Phase 1

Wingspan: 29.75"
Length: 22.75"
Weight: 4.5 oz
Motor:hand launch
Battery: 3.6V 300 mAh NiCad 3 cell
Servos: GWS Pico STD 5.4g (2)
Receiver: GWS GWR-4p 4 channel

This is the original fuse made with blue foam. Click on this image to compare to new fuse shown above. Well, my servos vere just form fit into little pockets and eventually worked loose enough to make handling suffer. Next phase fuse solves that.

This shows the dihedral I chose for my present skill level.

I bounced this guy on the nose a bunch and the battery never moved.

Phase 2

 
Wingspan: 29.75"
Length: 21.25"
Weight: 4.5 oz
Motor:hand launch
Battery: 3.6V 300 mAh NiCad 3 cell
Servos: GWS Pico STD 5.4g (2)
Receiver: GWS GWR-4p 4 channel

(This is the large photo above.)

 

Fuse is 1.25" shorter. Wing moved back for correct CG.

Made of balsa, it is much easier to re-model !

 

 

 

Here is a side view of the new fuse.
