Big thanks to www.FrSky-RC.com for providing the Receiver unit for this project :)
This model starts life as a free flight hand launch model, the type you put together and just throw it. When I seen this in the shop for just €9.95 I couldn't resist. I already seen it looked a lot like the popular "Fox" but this although a bit heavier flies lots better.

So here's the model simply "put together" as it would be normally, on the box you can see it comes in black and Red so if you have friends to fly with you can choose what NincoAir glider to buy

NOTE: Mark out where the STOCK COG (Centre Of Gravity) is by finding it's balancing point and marking it (on some tape if like me if you don't want to mark the fuselage).
/theme/Nincoair redwing/2-stock weight
The Multiplex is about 10 or more grams lighter (various places say different weights) but either way the NincoAir Red wing started life being 63 grams in weight. That's pretty damn light but lets not forget that for slope soaring weight is needed to get forward in the wind.

I had seen a Youtube movie by mickeydetanneron ([a]www.youtube.com/watch?v=vBol-Ujgiks[/a]) where he converted a Multiplex Fox with Pitcherons (or wingerons as their also known). The idea too me is crazy not because I don't think it work but the resulting roll speeds if it does work!. So here I began by cutting the wing center out 4MM after the mould line. Note I first drew out a line where the rods will go.

I used 4MM/3MM control line piping with 3MM Carbon Fibre inside. The control line piping is CA glued in place.

Now the center also has control line piping for the carbon fibre rod to pass through giving the pivot area. So each wing can freely move around its center point.

Ignore these type of servos but note their position, only the control arms pass the level of the center wing area. The servos are standing on their sides not flat into the fuselage.
/theme/Nincoair redwing/7-electronics mock up
I used 2MM metal rod inside the edge of the wings, this goes through the control horn as a pivot so when the servo arm moves up the back of the wing does and vice versa. However there is enough room to still unscrew the control horns so the wings can be removed!

The receiver is tucked in at the back of the pod area embedded so when the lid goes on it sits flat.

Here you can see clearly how the servos for pitcherons are fitted.
/theme/Nincoair redwing/9-first complete
This is how I first finished the model, I finally found time to fly it locally but noticed that in gusty wind where you turn sharp you drop lots of height, we only have small slopes locally so that's bad! Also later the same day when just holding it ready to launch the silly HXT500 servo stripped it's gears from the wind force on the wing.
/theme/Nincoair redwing/10 MG servos 2S lipo
After going back to replace the servo I decided to replace both with Metal Gear servos to never have the same problem again. While at it I added a rudder by top mounting the servo embedded in the back of the pod area.

Finally due to the MG servo weight etc I had 2 options, either to add lead to counter balance or use a bigger lipo. So I opted for a Nine Eagles 2S 250mAh lipo pack now using velcro.
So it didn't go right quite at first but I stuck with it and in the end I was flying this model in BFT 6-7! (although I had to add an extra 30g of lead for it) It was super fun and because of the pitcherons I had lots of time to do many spins before even really losing height
