What plastic props are these?

[befu]

I got three of these in a set of props that I purchased. Well, now we are building small solar powered boats for a learning project, and these work well with the Maxon motors I have. I only have three and would like to pick up a couple more.

Anyone recognize them? figure they must have come off some box RC boat RTR.

They are for an 1/8" shaft, no threads, no drive dog teeth either. 40mm diameter.

Where are they available from or something very similar. Trying to build small boats with solar cells and want the same setup for each craft, makes the design competition easier.

They look like they are off a Great planes wildcat. I had one as my first boat.

Also off the wave rocket.
Here ya go.

Wow, that looks like them but the specs are way off!?!?

It says 3mm washers and lock nuts, so the prop might fit snugly on a 3.2mm shaft which they do, but the specs say prop hole is 4.1mm and diameter is 33mm?

The wild cat ones are 1.5" or 38.1mm
These deffo have a 3mm shaft as they are still in my old springer type tow boat.

Tower need to work on their maths a bit.
1.5" is 38mm not 33

Hmm, guess I could have checked the math also, didn't think about that!

Thank you again sir!
