Putting on your own gear is fine but please be very carefull and take note of where the wheels are in relation to the CG.
The Quest has swept
back landing gear that puts the wheels in the right place. If you move the wheels forward the tail will tend to "bang" down hard on landing. This is not good for the airframe. Try lifting the tail about six inches and then letting it go. With the wheels in the right place it should be a soft bounce.
When the tail goes down too fast it is hard to keep the plane on the ground during any landing.
Try a seach with google using "Bolly landing gear". I use the FAI std swept landing gear. Each site has the dimensions that you need to know. I bought my last set from Dessert Aircraft at the WRAM show.

I installed my own LG and tires from my old pattern bird, as I attach using wood screws that will just pull out, not take the whole block if I dink it. The Sullivan tires look good and add (directional stability.

) The wide base also spreads the load over a greater area.
