It is recommended that a 'stab' rx is not only mounted level (and the right way round) but close to the CofG to achieve the best the roll, pitch and yaw sensing. Not so easy to do in a Wing...

An 18A ESC will be running pretty close to its limit as a 2812 with a 7x6 can draw a good 15A.

The boom does indeed go to that point or rather slightly beyond as there should be two small holes at the end of the boom for the screws to screw into.

Whilst moving the tail and servos back to make more room for a bigger battery is a sound idea you may find you will need one just to keep the balance point where it was.

I agree with yannc. The stock brushed/NiMH WD4 is perfectly adequate and you will learn a lot but do not expect it to lift any extra weight without a motor/battery upgrade.

Google "Wing Dragon" and it brings up some UK suppliers who appear to have stock of the WD4 at around 85. Uk delivery seems less than 10 but I expect Ireland would be more.

Differential ailerons - more "up" than "down". This means more drag on the up (inside) aileron than on the down (outside) so it helps the plane into a turn.
