Homebuilt ROVs Forum

I've been searching for a couple days now, mostly though on-line hobby shops and no one has them in stock! There appears to be no US manufacturer and orders are only filled roughly once a year by most places. I need three 50mm counter-clockwise and one clockwise rotating prop. Please help!

I use the Robbe 3 Blade Plastic Propeller in 50mm, they have both left and right versions.

Steve,

Thanks a ton! I just placed an order. I also got one shaft/stuff box and a set of wheel collars to play with. I will probably use a prop adapter similar to yours for the other three motors. What do you call the base piece with the tapping hole? I'm a bit leery of relying on epoxy clay to hold the unit together. Now onto finding suitable mounts for the Johnson pump cartridges. No fabricating for me. I wish I had a shop like yours!!

Cheers,
Bret

About the mounts for the johnson bilge pumps:

Mounts for the motors has always been my biggest problem. Luckily, I found these 2" pipe straps at the plumbing store. They fit perfectly on the 500 GPH motor cartridges. I recommend these if you are needing a way to mount them

here is a sight that sells hobby things

You can also use rc plane props and a spinner. Like the rov kit at inventive Inc. I used rc props one of my rovs and it work't well

Thanks,

I went with Harbor Models for the props and Tower Hobbies for the mounting coupler. Used a cut, 4mm screw and seems to work like a charm (i still have to test). I also found a perfect piece of pvc and use a dremmel to carve out grooves for a slide and lock (locking tabs were already present on the bilge cartridge). It fits nice and snug

Nice work

Harbor Models

Best place to buy them from.

They are my favorites, beside many model parts also a heap of electronic stuff. The parcels were in Thailand 4 days after ordering, so speed is no magic with them.
success!
