Champ RTF – How to upgrade your stock tires to the Du-Bro Tundra tires

Finally got around to upgrading the horribly small stock tires to the Du-Bro 150MW Tundra tires.  What a huge difference these make during landings, as well as looks for the plane.

I will apologize in advanced for the crappy pictures, I could not my find my battery charger for my normal camera that day so I had to use my phone camera.

Tools you will need:

  • Hobby Knife
  • Glue
  • Your hands

Here’s some info on the wheels, you can order them from various places including

Part number: DU-BRO 150 MW Tundra Tires 1-1/2″ Mini Lite Wheels

Step 1.  With your hobby knife make a small incision on the battery holder velcro at the bottom of the plane.  One you make the incision, you can gently using your hand rock the landing gear and tires out of the belly of the fuselage.

Step 2. You will now need to remove the hubs in order to remove the stock wheels and tires. Simply use your hands and carefully twist them outward until they come out.

Once you remove the hub/lug from the landing gear the wheels should slide right out.  The Du-Bro 150mw wheels slide right in, and the hub fits almost perfectly back on.  I used a small dab of Gorilla glue to keep them in place.

Here’s a side-by-side comparison of the stock tires and the Tundra tires from Du-Bro.

Step 3.  Once I mount the wheels back on and put the hub back on, we are pretty much ready to fly again.   Make sure that the hub is not on too tight or the wheels will not spin freely which will make landings and taking off challenging.   That’s it folks!

    So how does this effect your flying? The little wheels make most grass take offs fairly tough.

    @Doug – With the stock motor it makes flying a little more challenging, however, with the upgrade motor it makes a big diff.

    Great idea adding the bigger wheels. Really helps with landing. Actually helps balance the plane better in flight. Thanks for passing this on and the detailed instructions.
