Hi Velcomrob,


Yes it is normal that it spins counter rotor way, if you're flying in normal mode and if you didn't set a curve (or %) of compensation of you radio. If you did all that, I cannot explain, but if you forgot that, look in you radio menu for this curve and give it a little slop first and try again. Repeat the step until this effect disappears and you won't need to compensate anymore.
The normal mode is useful to trim your rudder right and set the link correctly so that you use as less trim as possible on your radio, then the servo works properly around its idle position.
When you switch to HH mode, don't forget to cancel the curve (or %) of compensation, otherwise you will notice this effect again (but on the other side).

Have fun
