So I started revisiting the plans of the Stick to correct the causes of the fatal crash (fuse wasn't rigid enough and the wing wasn't attached solidly enough to withstand the crazy power of the motor) and soon I'll build the Stick v2.
In the meantime I purchased this plane. She is so gorgeous I couldn't resist. And I found an offer too so it really didn't take long before I became the proud owner of one.
This is what I will be using in terms of electronics:
- Motor: Turnigy Park 480 1320kv
- ESC: Turnigy Plush 40A
- BEC: HK BEC 5A 5V
- Servos: 3 Turnigy MG90S for ailerons and rudder, and 1 HKS-9650 for the tail feathers, as I read
that more torque is welcome to pull out of high speed dives.
Today I slowly started the build, I am modyfing things here and there taking into account what I read on this very interesting article from Ken Schroeter's blog. I am dividing the build in multiple articles so I can focus more on some details without making the log impossibly long.
I am starting with the wings, so here we go.
|The box she came in. As mentioned everywhere on the world wide web, the image represents the flawed v1, but the code "18652" is used to identify v2.|
The wings are really well made, the cote is tight and well trimmed. They are mainly built up using light laser cut 2 and 3mm ply, with balsa struts and they are very light: I weighted one at 85 grams.
Also, they are detachable for transport, which is a huge plus!

|Surgery has started, and the skin removed (yuk..)|
|The aileron servo housing is made of a 1,5mm balsa sheet, doubled for strength.|
|Nice pattern for the various parts to join like a puzzle and form the sheeted part of the wing.|
|It seems that on the v2 some effort has been made to lighten up this plane, all the ply parts are drilled. Wingtip is solid balsa.|
|Covering has started. I aligned the checkered pattern to the leading edge. Note I am working on a towel not to scratch the upper skin of the wing.|
|Skin applied and aileron installed. There are 4 CA hinges for each aileron, which is plenty for this size of airplane.|
|Here I cut a X in the wing skin where with my finger I could feel the housing for the servo and then installed it. To remove any flutter I also applied some tape all along the junction between the aileron and the wing, in order to seal the cut.|
|The two wings finished and ready to be installed on the fuselage|
Here's the second part of the build!
