let me talk about the tail wheel first. the picture i posted was the 1st modification. Before she ever even had a flight. the tiller arm that came with the kit would not reach the hole of the ball link, that is glued into the rudder. the ball link, consequently has fallen off the rudder, glue did not hold it from the factory. also, the rubber of the tail wheel fell off the hub when i first started the motor, so i had to replace the tail wheel. You can also see from the picture that i had to use piano wire, and bend it, to help it reach past the ball link. well now, i have changed the complete tail wheel assembly. it now has a white rose wheel with a new tiller arm.. the ball link has been glued in deeper, and now after 27 flights, no problem. i cannot stress enough how important the tail wheel is, especially if you land and take off on asphalt.
