Right, an adjustment of the gain pot on the 4-in-1 will compensate, as well as adjusting left/right trim on the left stick of the tx... to a point. Not sure if it'd be enough to prevent the yaw of the tail, if one set of blades is cut considerably. I'd like to hear from someone who's tried it. However, as I stated above, when using the extended inner/outer shafts WITH a shorter flybar, I suspect that cutting blades would be totally unnecessary. Any blade strike that may happen to occur in spite of those mods, would be the result of trying to "over-control' the movement of the heli. You could get away with that on a CX/2, but if you move on to a CP or Trex, you'll want to get out of the habit of over-controlling anyway.
