RE: New Hangar 9 1.50 P-51 Build
To help take off and tracking on my Frankie I have the tail wheel on a separate servo which when switched off keeps the tail wheel straight. I then mixed in some right rudder with the throttle so once the plane is on the mains it requires almost no correction for a straight take off. This can also be placed on a switch but does not really seam a problem when flying. My plane also changes attitude with full flaps and gear down needing aileron correction to fly straight. I mixed in some aileron correction with full flaps so now it it continues to fly straight with full flaps and gear down making landing easier.
