Hi Sunny,
My controls surfaces are as follows.
Elevator for takeoff and landing +/- 35mm
Elevator during flight +/- 20mm
Aileron +13mm / -20mm
Rudder max throw you can get.
Take off flap 20 degrees (elevator down by 0.5mm measured at elevator root.)
Landing flap 85 degrees (elevator down by 2.5mm measured at elevator root.)

The CG is AFT of the wing tube. During test flight and subsequent flights, the CG was at the centre of the wing tube. The aircraft felt heavy especially during loops and required considerable elevator. Same was the case during landing, bit heavy and it was hard to flair the aircraft. After moving the CG just behind the wings tube, the aircraft feels light and flairs nicely on landings. I believe the CG can go further back but it is as per my flying style, I am happy with it.
