Split Zephyr

[paede]

I want to show you my split zephyr. the maiden flight was a few days ago. It flies very good. the hardest part was to launch it myself. It is a lot easyier to have someone else who throws the zeph.
I had to build a zeph that I can transport easy in my car, so that there is still some place left for my new born daughter and her stuff. Otherwise my wife wouldn't let me take the zeph on vacation ;-)

ok now the specs:
2.4GHz R/C (Hitec Aurora 9)
Servos:BMS 630MG
Motor: NTM propdrive series (HK)
ESC: Turnigy plush 40A
Battery: 2*3s2200mAh nanotech or 2*3s3000mAh Zippy

Camera: KX-171 G2
Videosystem: 2*1.2GHz 500mW Videotransmitter
Antenna: 1 RHCP and 1 LHCP cloverleaf in an anlge of 90° to each other

OSD: Eagletree Logger + GPS + OSD + Guardian
Variometer: Skymelody

Onboard recording: GoPro

Total weight: with 2200mAh battery 2000g, with 3000mAh battery 2200g

Building the split parts:
I ordered the zeph already split in 2 wingparts and 1 centerpart (in two halfes). chris also sent me aluminium tube pieces that fit exactly on the main spars.
First I had to glue the centerpart together and I glued the main spars in (Don't glue the last 5cm from the edge of the foam). I cut the main spars the same length as the foam. Next I glued the alupieces onto the main spars.
on the wingparts I had to drill bigger holes for the aluparts. Then I glued the main spars into the wingparts without putting some glue in the first 5cm of the hole. that was the most difficult part. (I used a straw to put gorilla glue deeper into the hole)
As you can see I made removeable winglets.
All the electronics on the wingparts were joined with sub-d plugs. (see pictures)

I painted the zeph in signal-red for other paragliders or gliders to see it better.

Why do you have two Video Transmitters on there? Just curious...

How heavy is your Zeph ?
BTW, this is not a split wing
look at mine, the gap is larger than wing cores
the wing is quiet and 3-axis gyro stabilized

How does that thing fly with the battery disconnected? =]

[fmkit]

here is air-to-air picture of the wing. it had one motor back then

if you really split wing halves prop can suck all the air it wants also without much noise, the motor is at CG so one can try whatever prop/motor combination without moving battery

Paede, VERY COOL! Do you have any problems with wing flutter?

Is there any other thing connecting the pieces together besides spars and d-sub connectors?
