Hi

I bought a 4Ch Dynam I can fly RC Plane. This is my first RC plane.

1 - I want to fly it straight with controls in neutral position. Can some1 help me with adjusting the control throws ? What should be the proper control throw for this plane?

2- I have inserted the push rods in the second hole of the horn as given in the manual. But when I try to run the plane on the ground, It automatically starts steering left after some distance. Even though my rudder is perfectly aligned with the vertical stabliser. Is this usual ??
But I feel the vertical stabliser is little bit curved (not vertical perfectly)

3- I m also getting unequal throws on the rudder. How to correct this ?

4- I am getting less elevator movement in the upward direction because its movemebt is blocked by the rudder. Is this supposed to happen ?

Plz help me..
