Hi just converted one of these left the stab as it is but had to shift wheels forward by 2inches to get the balance right for tail dragger ran and extra pivot point in the fuse so that i could steer the tail wheel setup ,basically what I did was put a vertical 3/16 rod in attached two servo arms on it one for tail wheel and one for rudder with one feed back to the servo and worked on a pull pull system, I then took the skid of the back carved a block for mounting wheel and hey presto done then put a 90 motor on it maiden flight comes next week ho hum !!!!
