I built the stabs to be removable at the field [with the STICK, the fin and rudder were also changed]. I used the same control horns adjusted to the same length. If you read my first post I didn't say there is NO difference, I said it's not likely you will notice it. I think as the planes get larger/heavier there may be a larger difference, but from a RC pilot's point of view you still may not notice. :^)
