When I originally built my Micro Moth, I used a bent finishing nail as a cheap and easy, lightweight landing skid.
This seemed to work okay, and it was certainly strong enough, but the sound the plane made on the ground was horrible. The ground handling was atrocious, too, but I didn’t blame that on the skid.
The epoxy on the nail came loose and I thought, what the heck, and glued a tail wheel in there, instead. (I’m not sure where this wheel came from, originally.)
It’s a steerable wheel, but I didn’t hook it up for steering.
The results are astounding. Not only is the model a lot quieter when rolling on the ground but, even though it’s not a steerable wheel, ground handling has improved drastically. It’s an order of magnitude better than before.
No more skids for me.
