No problem Rich, if your taking it down the lake tomorrow make it in the afternoon and I'll wonder around (I'm busy in the morning) I want to see what the ducks do, although as they have never seen a whale before they will probably ignore it.
 
Give me a quick call if you  do come over.

Will do mate...as long as you promise not to take the mick out of my shark/whale/fish/creature, whatever the thing is. A whark? Or a shale?

I had to stick a section of styrene sheet across the bottom of the nose section in order to pull things into shape and get the two sections to fit together. One way or another it WILL fit!   >>:-(

Well...it's been in the bath for the first trials. There's good news, and there's bad news.


The good news is that the creature floats nicely in the bath, needs a fair bit of lead yet, but at least it sits level. Which is good...


The bad news is that the Otter Box leaks...I'm guessing that the water is creeping up the rudder tube. Which is bad...

The sharks teeth are made by BECC, those of the flags and vinyl stickers manufactures. Just bought some for my semi scale conversion of a ready to run police boat ( now an american  Vietnam type patrol boat ) I hope to run it on Sunday and make sure everything works first before using them. Regards, Dave.

That I could do something with...I like that, Kev.


I've made up a whole new rudder linkage and used rubber bellows this time. Just waiting on the glue to set hard, then it's back in the bath for further trials.

I always have my corals in back to front, it's the only way they fit...   :o


Fear not, Dave...they weren't on properly then, they are now. Apologies for the photo, the phone battery needs a charge.

It started off as an MMB Sub Sonic, Pete...but sort of got slightly altered along the way.

I've decided to rebuild the shark/Orca/whatever you want to call it...I'm not happy with the way it looks.  I've had a chat to Mark @ MMB, he's moulding me up two Sonic lower hull sections in the same off white colour, and I've worked out a way of getting them to line up (no offence meant, Mark..) I've practically completed a new cylinder ready for it, so as soon as the hulls arrive I can get cracking on the new version.

I've also worked out how to get the two foreplanes (fins?) to work independently, so that will allow me to carry out barrel rolls underwater.

This is rapidly becoming an obsession now... ;D

With that dorsal fin I would hardly think barrel rolls would be possible. I wonder if you could put a leveler perpendicular to the normal alignment and keep the shark/orca fro tipping?

when we got so close rich, my wallet was ready for the first order. I have got some rc plane project out of the way, so might return to the shark soon. I think the fins would need to be like ailerons on a plane for the rolls, but forget all that, just do one that dives to periscope depth, just for me, its nearly Christmas!

I was hoping Andy would surprise us with something :}

Tom...here's a picture of an Orca that can do barrel rolls underwater...note the independent forward vanes(fins)and the large dorsal fin.


Paul...fear not, Andy is cracking on with the shark, but work commitments are slowing him down, plus he's up to his ears in little jobs for people, (such as the turbine for my tractor) I spoke to him the other night, and on top of all that, he's not been to well recently, so things are running slowly at the present.


Once the hulls arrive and I have an idea of what's going to be what, I'll let you know...

Frank, I've studied that, watched the video umpteen times, and examined the drawings very closely. In fact, I very nearly bought a kit from Norbert, but then common sense kicked in when I saw the price of it.


I'll probably use one or two of Norbert's ideas on the new one when it comes...the cylinder is 99% completed now, just waiting on the new 40mHz rx's to arrive from HobbyKing and it's all done.
