Scudrunners

Left that prototype in the sun for a bit, this is how it looks at night.

First attempt at NACA plug.

I used TPU for the plug part (red), might be too hard for use but will try it out tomorrow.

I had to heat it up to slip over the hard part which I used PLA for.

Sweet! Now it looks like I'll have to take a trip to Calgary to show you how to tune that thing.
