Valentijn 1:7


Here’s a nice project I’ve been working on: It’s a 1:7 scale model of a Dutch lifeboat, is to be fitted with a 50 CC Blata driving twin 54 mm jets thru a MHZ gearbox. The model is 60 inches, built in glass/carbon epoxy/PVC foam. On DWL she should weigh about 25 kg, so I’ll probably have to add some weight to keep it in the water

Best regards,

Hi, no these are Chinese 54’s (they’re based on the old MHZ Race unit) I was able to get cheap and that I upgraded myself with SS-Ceramic bearings and lube-points front & back. Also added the SS ring placed over the front bearinghousing and canpainted them.

BR,

I see it's a vectored drive,is there a reverse bucket for them?
Is that a water pickup nipple at the rear for cooling purposes or the rear lubrication point?

I plan to make the reversebucket myself.
Yeah thats the water-pickup.
Lube nipple is in the back of the stator

Haje74, your hull build is very inspiring. That much “glass work” takes skills. I also like the way you did the grease fitting for the stator bearing. If you don't mind, I would like to try that in the 45mm jet drive I will soon put in a “glass” (Kevlar) hull I'm building.

Sure! I only got the idea by looking at pictures of jetunits by MHZ anyway (I used the SS type)..

The project has been on hold for some time until recently. Now, with the completion of the 2 drives I plan to restart the build.
