How to make your own propellers?

[Kyle_Guo]

I have been using Ikara propellers like the ones given to you in FF kits and trimming them to 14 cm. Every time I adjust the pitch when testing, it leaves behind a white outline of where the plastic stretched to make the new pitch. After adjusting the pitch another time, the plastic becomes really weak and easily cracks when hitting a wall. I have broken several propellers now and want to make my own propellers so that you can just make them at the angle you want them and make several at different angles instead of destroying perfectly good propellers.

Back when I was competing our school bought so many kits but only a couple planes survived, so we had many extra propellers. I met with a local flyer and we experimented with pitch by adjusting each to a different pitch. Before adjusting, he dropped some solvent on spar that supposedly prevents the white stretch marks. Freedom Flight sells individual propellers.

I'm not aware of adjustable pitch balsa propellers, especially for the rpm needed for Wright Stuff planes. At such rotational velocities, air resistance may change pitch settings.

We had a hard time finding a good plastic box to carry the Fun Science 2017 plane by Freedom Flight Models. We have a 38" x 21" x 6.5" (LxWxH) Rubbermaid box which is a bit shallow. Any info. on or suggestion for appropriate container(s) would be appreciated.

What are the dimensions of your disassembled plane?

Thanks for the link to the Storable. Unfortunately nothing suits. We try not to disassemble the plane every time after practice. The box we have now is a bit too shallow (6.5") for the plane's comfort. A box of INTERIOR dimensions 27" x 27" x 10" would be perfect.

You'll have a hard time finding plastic storage containers (that aren't overly oversized) capable of storing an assembled plane. Record your measurements, disassemble your plane and store in your current box, or make your own, probably involving woodshop equipment.
