I finally got a dual nozzle 3D printer, making it possible to print main blades for my S1 using 2 different materials (1 for the blades and 1 for support material).

I went a little extreme on the trailing edge design on these, but they fly great, as-is. I'll continue to tweak the design and test, but so far I'm happy. They're quiet and very snappy on cyclic.

It's amazing what the S1 flight controller will tolerate. I've flown up to 155mm mains with a stretched boom and lately I've been switching between 125, 130 and 135mm blades that I've designed and printed.

All blades I've made so far are based around NACA0012 airfoil. Next steps will be tweaking the trailing edge design and moving the blade root closer and further from the leading edge for testing.

The S1 absolutely RIPS!! I love this heli more and more every flight.

It gets small so quickly! It needed something to help my aging eyes keep track of it.

Been testing a new tri-blade on the tail today. After a dozen or so flights putting a beating on it, I'm happy with the performance.

You can download the model for free and try it yourself. I uploaded a few other S1 parts, too.

Just trying to get an idea of interest level for 3D printable S1 parts. So far I've designed, printed and tested booms, skids and tail rotor blade. I've also made a few other little things for it, like wire guides, a swash leveling tool and a stretched boom to run longer main blades. If there's enough interest, I will upload the models to Printables.

OEM replacement parts are cheap for these things, but 3D printed ones and pennies to make.

I've done a lot of flights with these parts; testing, crashing, revising, testing again etc.. They're at a point that I'm satisfied that they're ready to release to the public if the interest is there.

I'd also like to know of other printed parts S1 owners may be interested in.
