Maxon EC22HD  $1200 each :o :o no not a misprint! I need four. Seeing as I don't have the odd $5000 to spare I think these are in the NO category :embarrassed:

Thanks all the same Timebandit.

Regular price should be between 100-200, not so sure what you found there.
You'll find them pretty often at ebay at leadt here in germany.

Tobias that pricing was from the parent site in USA, the model I looked at is very high tech, way more than I ever could need. Produced for underwater work down to 17000ft.

On the motor side I think you will struggle to find a motor that can swing X2 55mm 4 blade brass props and be smaller than 23mm in diameter . I have seen it done on  a single prop pod but not a double

I've located a supply of either nylon or brass or aluminium gears. Made for customising slot cars (Scalextric) they come in various ratios and are secured by grub screws, they are not bevel gears but crown and pinion, so they will do the same job in a different way! Not bad pricing either-- I can afford these :}

thanks everyone for your suggestions and input.

I am glad you have found something Brian. I read somewhere on the forum recently that Nylon expands to by a finite amount when/if submerged in water. It might have been in a thread about washers or prop shafts, I thought I would bring it to your attention so you can gauge tolerances when designing your pods.

You don't want gummed up pods now do you {:-{

Especially when they will be sealed for good once built.
