Cularis twin motor

I just got home after maiden flight of my upgraded Cularis. I have 2 wing sets, and I put motors on one of them.
My set up:
Motors, Turnigy SK3530-1100
Propellers, APC-E 11 x5.5
ESC, Castle Phoenix 45
Battery, 3-cell LiPo, 5000 mAh
It's still dark season here in the arctic part of Norway, but weather was perfect and my patience was low, so I went out for a maiden flight.
It flew straight out of my hand, no trimming, and plenty of power for climb out - and best of all next to total silent flight.
There is still room for all the FPV gear I need, so I'm hoping for long and high cruises later this winter.

My next FPV-project is a 6 meter K8b from Phoenix models. I have 2 wing sets for this AC to. I plan to put in a pair of 3 KW motors, remove lead from the nose (almost 3 kg) and replace it with LiPos. This could be something for really high "exploration of the atmosphere".

Nice quad! How big is it, or should I ask how small it is?

here's my new 90" motorglider, set up with 3 2200 3s in series, so it should get 40 minutes to an hour of runtime
90" foamboard motorglider overview (2 min 19 sec)

gonna head out in about an hour to fly it fpv for the first time (already had it out on the slope, it flies fine)

Thanks !
The front bar is 18cm. The flight time is apro 7 minutes with a 1400mAh. I am using 5030 props on it. A instruction of how to build it can be found here ( version 3):
http://www.schaefers-daheim.de/index...owall=&start=1

Version 4 had the controller bit more to the back and version 5 inside ( which has the advantage of protecting it a bit more ). The frame is really tough since it is very light and stable. I built about 7 of them One flying kk2, one MultiWii and the rest of them KK1 with firmware > 4.6

This is my first experience with FPV. My brother and I built this wing together. It used the dimensions of the ZII, but we chose a KF-m4 airfoil. It flies wonderfully and is equally stable at extremely high and low airspeeds. We flew with a buddy box for our first FPV flights today and the whole experience was such a thrill!

Equipment:
Motor: Turnigy D3542/5 1250KV
ESC: HobbyKing Red Brick 60A ESC (Opto)
Prop: Master Airscrew 8.5x6 pusher
Servos: HK15138 38g/4.3kg/0.17s
RX: Berg 7P
Motor Battery: 2 x 4S 2200mAh (4S2P 4400mAh)
RX Battery: 4.8V 600mAh Ni-Cad

FPV setup:
TX/RX: Hobbyking 900MHz 800mW
Camera: SC2000 PZ0420
Battery: 3S 500mAh
Monitor: Haier 7"
Pan-Tilt: Homemade with two HXT900s

Any questions? Just ask!

So why the heavy nicad? Lot of people think that a separate receiver battery is just another fail point vs it being redundant. And why not NiMH? Looks nice. Who cut the wing for you?

Shadrack,

The Ni-Cad situation actually started as an "oops". I accidentally bought the Red Brick "opto" version, the one that doesn't have a BEC built in. All of my other RX packs are in other airplanes, so this one ended up going in. I might choose to change this setup soon. It sure is clunky, with all the extra weight and space. To be perfectly honest, I needed to get this wing in the air before I leave the shop and head back to college. Even with a changed pack, I'm not sure that I would notice much of a difference.

My brother and I made the wing ourselves. It's just 1/2" Owen's Corner pink foam. Nothing fancy, that's for sure. She does her job well though. Now to finish building some real antennas...

Huge ups and big love for going on your own and scratch building your own craft!
I can't tell you how awesome that is compared to another box-built airplane with the same names showing up every day. Great adventure, great job.

Thank you for the kind words. It is rewarding; that's for sure. I've done some scratch building in the balsa world and it's always a special moment when you've taken raw materials--like an 8' x 4' foam sheet--built something substantial with aerodynamic properties, and then trust it enough to put a few hundred dollars on it and fly it several hundred feet in the air.

My brother and I are heading out for a flight on the beach today. I'm quickly getting hooked by this niche of the hobby.
