FliteTest Baby Blender with 3D Printed Landing Gear

This past week I designed and printed a simple set of front landing gear for my FliteTest baby blender scratch build.

Nothing can top 3D printing when you want to create complex geometry. Each side of the gear is designed with a 3 tapered legs intersecting on an axel hub.

The highest point of each support is 1/4 of an inch in diameter and expands to 1/3 of an inch near the hub. The center supports cross and interlace for extra lateral strength. This design includes a cutout to fit around the 9 gram aileron servo.

The gear is attached using simple hot glue to the bottom of the wing. Take time to ensure the ear is square to your wings. Any misalignment here will lear to a plane that taxies to one side or another.

Also note this is most likely going to be the weak point. On hard hits the paper might give way but for now it is solid and stable.

All I had in the shop were a set of small wheels but they do the job just fine. Someday down the road I’ll get a larger set. I used a insulation wire supports for the axel. They are cheap, easy to find at any big box hardware store and plenty rugged for this light plane.

If I had to do it again I would push the wheels a bit wider giving the gear a more angular look. I might also make them a bit shorter. With this configuration the rudder drags on the ground.

As always the print files can be found on Thingiverse. Please comment below and let us know what you think.

Next up is to design a rear steerable wheel mount and make this a true tail dragger!
