Tail Wheel Replacement

Challenger Tail Wheel Replacement


Stock tail wheel replaced with rubber coated wheel from Harbor Freight and Salvage.  Gives a little more cushion when lowing the tail and moving the plane around.


Reinforcing the Tail

Sheet metal on tail

By triangulating the tail with thin aluminum it removes approx 80% of the twisting motion in this area.

Note it does not change the shape of the plane in any way but does add weight.
