Introduction

Another wing! I was looking for something smaller than the FX-61 and easy to throw in the car or on my FPV backpack. A fellow RCGroups poster brought this up in a post so I checked it out and was pleasantly surprised by what I saw. It is basically the "missing link" between the 1550mm FX-61 and the 800mm WingWing Z-84!

So I ordered the kit and was again very pleased with the plane itself when it arrived. It has some great features like bottom mounted servos with through-wing accommodations for top-side linkage. This keeps the weight low in the airframe and also keeps the linkage from snagging on grass or weeds when landing. It has two different nose pieces, one for a camera and one that is just solid EPO. The Hatch has a front key to hold the nose down and two snap in hold downs that seem to work very well. It also comes with a nice low profile tow hook and skid piece. All in all, some nice improvements over the FX airframe.

General Specifications

Distributor - BangGood USA
Aircraft - C1 Chaser Wing
Build Date - January, 2017

Wings & Fuse

Pretty much a straightforward build. No decision whether to make the wings remove-able or not. The elevons are dense enough to use the stock control horns and when it is all glued together it seems quite stiff.

For glue I use E6000 which is similar to UHU POR and Zap Goo. It has a 24 hour cure time which really should be followed and it is very strong with EPO foam. The following list are key points to my build:

• The stock motor mount is garbage (like the FX-61) so I designed up a 3D print version
• Laminated the leading edge with 50mm wide strips
• Laminated the wing joins with 80mm wide strips
• Put three blenderm tape strips on each elevon

Controls and Linkage

For this build I decided to use some small digital servos, the Turnigy D561MG Coreless servo which weighs 7.5g and makes a respectful 1.2kg/cm with 5.2v. These may be a bit undersized for this wing so some flight testing will be in order.

On the linkage parts I am using the stock control horns with 2mm link wires, Dubro 2mm ball joints and 2mm Qwik-Clips. I use the ball joints anytime the linkage is not perpendicular to the control surfaces. This is the best way to deal with high linkage miss-alignment.

Battery, Motor & Prop

For a pack I decided to use LiIon which I already had. In this case a 3500mAh/4S single pack of NCR18650GA cells. These are fairly good cells with decent charge cycle life and a max continuous current rating of 10A.

I chose the Cobra 2213/22-1100kv motor because I am a Cobra fan and it seems to fit (on paper) very well for this weight and size airframe. I also have a Cobra 2213/26-950kv that I may try for high efficiency at some point. Both motors are exceptionally smooth and light.

Because it is a wing I chose an Aeronaut folding prop. With the motor and pack selection I will use an 8x7 blade set on a 38mm center piece (yoke). Below is a simple set of static tests with these components. It should be noted that I live at 2550ft ASL (777m) so these tests reflect this altitude.
