Nice little prop and driveline for micros

[Ryan_from_OHio]

While searching for drive components for my 11" Cat Im building I come across the perfect little item, thought I would share my find.

The cat Im builing will utilize a small slotcar motor, which has a .079" diameter shaft. Well at the hobby store hanging on the wall was a prop mounted on a straight shaft, which appeared to be the same size. I spent the $4 for the prop joined to the shaft. Got home and it was the same size. The prop was dull so I sharpened it up.

I think this prop system will work farily good. Just for the fun I hooked the motor up to it and used a 5V power supply to see what it did in the sink. Lots of water movement which was very encouraging.

The info:
Hobby Zone HBZ3327 Propeller w/shaft : ZZR

This prop is meant for a small elkectric boat. Cant remember the name for it but looks perfect for my application.

Will let you all know how it works after I complete the project.

Ryan, 11" cat very cool, what does the motor draw?, I was reviewing some sight (sorry can't remember which) and they were talking cobalt motors for slot cars, also very very cool, look around for some very old dumas props (I believe they were made by JG, I have some that couldn't be more then say 22mm wonder if it work??? post some pics, also check the gallery board for some posts by "dongskie" he also had a very small hydro pretty cool, good luck, eddie

Thanks for the encouragement.

The motor I am using is a smal mabuchi (of course) that was marketed to the slot car market as a cheap sealed stock motor. Nothing fancy, but will doo around 30,000 RPM at 12 volts. I am driving it with a total of 8 parallel AAA rechargeables, for a good 9.6V, but in actualaity it over 10V.

I did a bath tub test, with only 4 cells it was rather week. I had some problems getting the torque to the prop.

All in all should be ok.

Will get an update once completed.
