O RON!!! You hit me in my soft spot again with the corvette look alike comment. And yes now that u have more pics I really do see. Well more about hulls

DDs = very sleek and fast looking when it isn't moving

Corvettes = like a big invincible bathtub

Ron Lad,
I posted this question yesterday but don't see it. What filler are you using?
I use 'Isopon P38' and it sure ain't that or is it? The hardener with the 'Isopon' is red and yours is yellow. Does it sand well?

You're certainly cracking on with this one. Pleased to see the 'Corvette' comment as I had that idea when looking at the photos.

Thanks Guys, This is what I use. Sorry guys I thought I had posted a picture of the filla and hardner, but on checking the last two builds it seems I had not.

enjoy, ARH,

Morning Ron Lad,

Thank you for that.

Pressing on with my BP Boat ASRL. I'm sorry to say it's not scratchbuilt but is one of George Turner's kits and I'm impressed. I'm changing it from single to two working props and one dummy (detachable for sailing) and three rudders and not one, two ESCs.......I must be mad.

Hi Guys, I have put in some of the strengthening timbers, at the bow and stern I cut out some 1/4 plywood, the middle section was 1/4 x 1/4 pinewood slightly bent to take the sheer of the deck.

The timber was screwed through the hull with small screws, and bracing sections fitted, these had the camber of the deck sanded to shape.

I marked the deck level with a pencil just to show the sheer of the hull.

After fitting the timber I trimmed the top of the hull to a resonable finish.

A nice over head shot, this will be the size of the battery I will be using in the model.

enjoy, ARH

Sheeesh!--Thats Huuuuge!--looks like something from a motorcycle!

Is it deliberate--ie to gain displacement?--In the model aeroplane electric flight world they have these batteries that are the size of a box of matches and will spin a brushless motor for eons.

Just curious--I know little or nothing about RC stuff--I fly my plane--badly--occasionally....!!

That is just incredible! I am eagerly awaiting more shots of this project - outstanding!!!

Jim, in R/C thats small, Iron Duke had 2 larger than that, we use battery power for ballast, other than lots of lead wieghts, more sailing time,

Hi Ron It wont be long before you have the deck cut and in place . You are certainly "on a roll"

Hi Guys, Like I said , I cut the hull back to the deck level , even on the stern.

So now I have to rebuild it back, starting with a piece of hard polystyrene I cut it to the shape of the stern and waxed it.

Then I put on a lead weight to hold it in position.

Mixing some filla paste I laid a coat on the styrene and left it to harden.

I then sanded it to shape and took away the styrene.

Filled in the blemishes and resanded.

I put a straight piece on either side and extended the bulwarks, I cut them down to size and sanded to shape.

Stern shot, beginning to take shape.

Bow shot, still some work to do here.

Hi Guys, The next job is to fit the rudder,

I first mark out the position of the rudder post, then drill a hole to the correct size.

Then I cut a hollow tube of brass to the correct size and fit in to the hole, under the hull I put something to support the tube at the right heigth out of the hull.

The top of the tube needs to be 1 inch above the waterline.

Next I shaped a piece of timber and drilled a hole in the centre, mixing some paste I put it over the shaft and left to set.

This part has to be strong, I cleaned around the staft with sandpaper and left for 24 hours.

enjoy. ARH

Go on, admit it, you used to work for Blue Peter! ("Get down Shep! Now after applying a couple of bits of sticky back plastic your Destroyer should look like this...")

Just stunning progress, Oasis and Plaster, who would have thought of it? You have convinced me, going to have a go at making a fibreglass hull.

Hi Guys, The rudder its self is made of brass and fibra paste.

First I cut a piece of solid brass rod and drill it near the bottom, then I cut a second brass rod this time slightly thinner, pass it through the hole and soldier.

Check what it looks like and that it fits the shaft, also it comes above the hollow shaft already fitted by at least 1/2 inch

I always say, never throw anything away, as middle watch said , in my blue peter days, I found this earlier, the plastic container, I cut a slot in and placed the shaft inside.

I mixed some filla paste and put it in the tray, I then pushed the shaft into the paste.

I then filled it to the top and pressed a lid on top and left to dry.

When set you have a block of filla that you can mark out your shaped rudder.

Rudder sanded and shaped, and fit in position.

enjoy, ARH

Morning Ron Lad,

Like the rudder. Slightly different to the method I use to make them. I use the brass rod bit and two pieces plastic cut to shape, with, in my case, Isopon filler on one side then glue the other plastic piece around the edges. Clamp together and when dry I trim, sand (swear) off any filler that I need to get the required shape. Talking of which, wait until you see the rudders on this ASRL I doing, most peculiar!

I can't wait to see this one in her natural element.

Hi Guys, The next thing I did was to fix the arm on top of the rudder post.

The arm sits on top of the fixed outer shaft, the rudder can not drop down , this holds the rudder in place.

A full shot of the hull with rudder in place.
