Thank you Dr Khanna,  Rohit,  Gusty sir.

Here in shillong it is so windy now a days we are also eagerly waiting for calmer days and busy building. 

Gusty and myself tried a hand each on the model  this wednesday. Flew well for the first time.

Did not record flight video since light condition was not good and would not have done justice to the colour scheme.

Still some tweeking needs to done with DR and Expo to arrive at a perfect setting. Gusty was confident it will do a decent 3D.

I feel since Aileron response was good so it was OK toned down but the response of rudder and elevator was not so good so it needs to be toned up a bit. Gusty I would like to know your take on that before I do anything.

Need to do a chequered pattern under wing for better orientation.

The servo arms needs to be bigger, Throw setting will requires 5-7 flights to arrive at perfect throw and expo for different manoevres, Aileron throw needs to hit 65 deg for a decent rolling harrier, Since the span is big roll rate will be less especially in a right rolling harrier. can the rudder become bigger ?

Rudder and Elevator can surely be made bigger in the present configuration without disturbing the present hinges. I will try the lengthening of servo arms like how you have done in your yak and Addiction
