Ripcord Flyer

thingiverse

This is another flying toy project I've been wanting to get started for a long time. With a simple pull of the ripcord, you can launch propeller rings (or spinners as I prefer to call them) nearly 30 feet high or more than that horizontally. You'll need: * 2,608 bearings (not included) * 1 axle * 1 gear * 1 base * 1 handle * 1 or more spinners The spinner naming convention is as follows: * bld = blade * spr = spinner (or propeller ring or disk or whatever) * w = width * d = degree (for angle of attack) * h = height I've posted the spinners that performed the best based on my testing. ***UPDATE*** I'm experimenting with twisted blade spinners and have just posted a couple: 3 bld spr 120w 55d-20d 8h v3.stl and 3 bld spr 120w 55d-10d 8h v3.stl. Both fly awesome and I believe may be better than the flat blades, which was the hope (less drag). Want to make your own spinner? Please do and post it! I've posted a STEP file template so you can create your own. I'm excited to see what you come up with. CAUTION: Eye protection recommended. These are thin, 3D printed parts, most likely printed with a brittle plastic, which spin at high speed. I have had a couple of spinners shatter on launch. Happily, there were no injuries when this happened and since the spinner parts are very light, I think injury is unlikely, but it's always better to be safe than sorry. Also, don't use a ripcord if the stop tab breaks off, as it increases the chance of causing too much initial force on the spinner when launching. Have fun but be safe!
