I'm now working with a Belgian gentleman (the one who built that superb all singing, all dancing Orca) to get my shark Mk 2 built. Don't ask me to write his name, I wouldn't have a clue where to start!


This one will be a full hulled version, using two MMB SubSonic bottom hulls, made for me by Mark's daughter Hannah (thanks Hannah!)
I'm using some of this chap's ideas on mine, independently operating front vanes(fins) to allow me to do underwater aquabatics, fixed tail fins to keep the creature level, and a full radio box built into the hull using 4mm thick styrene (courtesy of Andy and Debbie at Models By Design) for the bulkheads and the top flange, and the usual clear lid.


All the required parts on the way, so it's now down to playing the waiting game for them to arrive...still, it gives me time to tidy up my work area.

Ah, thanks Andy...I didn't think his Facebook name was his proper name.

A quick update:


Andy (subculture) has the hulls and is doing a marvellous job on sorting them out so they will fit together. He's fitting flanges around both sections with locating pegs, and given both of them some heat treatment to bring them into shape. They now look so much better, I'm deeply indebted to him for doing this.


I have decided to go with a proper radio box this time round, using built in bulkheads, a top flange and a lexan top. I have all the materials needed, so as soon as the hulls are done I can get started almost right away.


The front fins (dive planes) are made and ready to install, these will control the depth of the shark, I've made them adjustable this time. A new motor, a new rx and a new esc are ready to install, plus an 11.1v 2250 lipo battery.

Bulkhead templates laid loosely in place, and the front fins in more or less the position where they will be fitted. Might even spray them this afternoon ready to install.

The two hull sections arrived today from Andy, and what a superb job he's made of them...they fit together properly now, and with the simple but effective method of locating them together, everything stays put.


He also made a new wtc for it, as the radio box wouldn't fit with the new flanges, so now it's full steam ahead on building the creature.


Thanks Andy..

Hi,

Have you any contact details for the Belgian gent who made the Orca?

If I go into submarines that is the model I want.

Regards

If you're a Facebook user, pop over to the Dive In group's page, Raf is a member there. If not, consider joining F/B, it's worth it just to join the Dive In group, especially if you're thinking of getting into submarines, and you don't have to use the rest of it if you don't wish to.

There's loads of pics of the creature in the photos section, and you can contact him via the pm service.

Raf's orca was really an adaptation of another hull. So, pretty much a one-off so I think it would be a lot of work to build one yourself, and that's assuming Raf sells the mouldings.

If you would like something sub aquatic and mammalian, Norbert Bruggen sells a very nice Dolphin kit. it isn't a cheap kit, but you will get something well thought out and engineered that will get you off to a flying start in this hobby. The finished models go like gangbusters on even a modest 540, and become seriously edgy when fitted with brushless motors.

Have a look here- http://modelluboot.de/KITS/Delfin_Ordner/Delfin.html

Rich, you or Andy got anywhere with this yet?
Cant believe this turned into such a difficult project,   I will get back to it soon, but still looking for something that I can buy!
