The pilot is raring to go and has been checking out the cockpit. Charlie was painted by a friend and what an absolutely superb job. The Aran jumper and Bomber jacket are wonderful. The metallic buckles and lifejacket are also extremely good. Now I must do the job justice with my finishings.

These photo's were taken last July by Marcel who had travelled from Switzerland in his VW T5. The Bwlch was just one of his stop off's on his round Britain slope trip. Believe it or not it is very difficult to Slope soar in Switzerland due to the all the trees. It also appears that all the mountains are privately owned, permission has to be asked to cross each farmers land. Therefore, he finds it much better here in the UK.

This morning I sealed the longerons and perimeter edges with watered down PVA. Then this evening I cut a paper template for the top deck covering. I used an off cut of turquoise Oracover to shrink down and leave the very distinctive ribbed shape.
I then masked around the Oracover leaving a small 5-8mm margin for the fibre glass to adhere directly to the surrounding balsa. Then I sprayed the Oracover with a list mist of 3M spray mount and then carefully applied the 200g/m2 of woven fibre glass. Using the spray mount securely holds the FG in place whilst wetting out and has no adverse effects. Using spray mount also allows you to really work the resin in sparingly without any puckering up or excessive movement or floating FG. I swear by the stuff.
All wetted out and overall I'm very pleased with the result. Hopefully, this method of covering will prove robust enough for some slope abuse.

In the past I have melted down lead and poured it into a sand mould to form nose weight in one of my slopers. However, for this project I jut wanted to make a bulb without too much hassle. The idea of making a plug then a mould and then the excitement! of melting lead wasn't that appealing. So I decided to cheat and make the bulb from seven lead profiles glued together.
I made a MDF template of the shape using french curves and went for the 'If it looks good it probably is good approach for the position of the fin. The lead was then cut with the kitchen scissors and stuck together with CT1.
Then after leaving it for 24hrs I have just started to round off the corners. It still needs a fair bit of sanding and then I'll wrap it in an old pair of tights and give it a couple of coats of resin and paint. As you can see it has quite a narrow shape to cut through the water, similar to the hull.

This is how I went about making my first fin. It started by purchasing a 1mm thick A3 size sheet of Carbon fibre. Cut two strips 50mm wide and cover the good face with low tack masking tape. Then chamfered the internal surfaces of the trailing edges (TE). Once done I taped the two TE's edge to edge and applied a thin bead of Gorrila epoxy. pic 1-2
Then folded one side over but spaced them apart at the leading edge (LE) and clamped the TE together. Once cured I cut a 4mm wide strip of carbon sheet and glued it just inside the LE which had previously been chamfered at roughly 45 degrees. Then I used epoxy to glue a 2mm dia carbon rod into the rebate to form a rounded LE. pic 3-4
It was then my intension to then push a 2mm dia rod inside the two skins to form an aerodynamic shape. However, as much as I tried I couldn't get the rod more than 12-13cm down inside the fin. So taking a big step backwards I split open the LE, positioned the spacer rod inside the fin and re glued together the LE. pic 5-6
All cleaned up and she looks pretty smart. A careful coat of clear nail varnish (Lacquer) on the LE a file to the TE and another polish and she'l be good to go. 395mm long 49mm wide 4mm thick she weighs 68g

Last night after a good dose of sanding Rebel was removed from the shadows. 2.5mm balsa, 1 wetted out layer 80g/m2 F/G and 2 subsequent coats of west resin. Present weight 84g or just under 3oz. I think I'm in the right field!

Added extra balsa to the wing leading edges to improve the profile which might have been a bit blunt. Also made a ply plate to help reinforce the area around the wing locating dowel which will be fitted at a later date.
Cut and fixed the upper deck longerons so now this model has really starting to take the form of a Hurricane.
The view of the tradesman's entrance shows the plastic tube which passes through the firewall and is fixed to the front of the GRP cowl. The tube will be loaded with balancing lead and the battery pack. The RX will be fitted to the ply plate on the left and the apertures for the servo's and switch have also been formed.
Work is still ongoing at the tail and a fair amount of fettling will be required to make this area more life like. At present and following the plan there's not a lot of scale detail with regards to fairing in this area.

Gosh! How does a forecast of a NW12-16mph wind just the day before be so wrong! At the lake it was more like Southerly 1-2mph with an occasional NW shift. Still we had 12 close races between a MX14, Goth EVO and Harry's BOR.
It was also the maiden of my first effort into IOM sailmaking. The conditions weren't exactly ideal but the shape appeared to be OK and once I got my head into gear and a couple of small tweaks later I managed to win a couple of races. However, I'm not going to read too much into todays results as the conditions were a little fluky. Lets hope for a little more wind in two weeks time what ever the weather man says.

Graham Bantock's, Brad Gibson's and MK's IOM sails. When making my next suit (which could be sooner than I thought) I think I will be adding to the luff and flattening the main. I'm pretty happy with the shape of the jib.
When I finally make a sail which I'm happy with I might purchase some double matt film!

Harry's IOM sails are now rigged and they aren't too bad. There is definitely room for some refinements to improve their shape but I'll play around for a little while before jumping into the next suit. I should also make sure that the next sails are legal and the sail numbers are correctly positioned. I was so keen to use my home made stencil I put the first number in the wrong location. I noticed my error almost at once but it was to late the pen had streaked it's black inky mark on the film so there was nothing I could do but complete the task somewhat gutted.
Still looking on the bright side the Hurricane is coming along nicely

I have finished making my first suits of sails both for Rebel a RG 65 and also a suit for Harry's IOM, Bor. Now we just have to wait till Sunday to see how Harry's new sails perform. Between now and then I just have to stencil in the sail numbers and fit them to the spars.
At the same time I have also been doing a bit to the Hurricane fuse including the upper decking, cockpit, cowl and wing tips.

Rebel's balsa core hull has been laminated with 1 layer of 80g/m2 fibre glass. I'm hoping this will be adequate and offer enough impact resistance. The internal surface of the hull will also be laminated around the high load areas of the fin box and mast.
I have also made my first suit of sails which in the whole was an enjoyable job. However, the mylar film sets in a better shape on one tack better than the other so perhaps I'll be making another suit pretty soon. This evening I've drawn out a new IOM main for my sons yacht and will turn the film over on each alternate panel to try and stabilise the shape. I can't be too fussy as I bought over 20m of 50 micron film for just over 8.00 inc p&p on eBay on Christmas Day! Unfortunately, it's not double matt sided so one side has a very glossy finish but I doubt this will have a major effect on actual performance.

Yep, here we have two poseurs showing off their 3D gliders. A brightly coloured Vagabond and a slightly more subtle (plain Jane) Traceur. Due to the pretty windy conditions and a couple of test crashes they were grounded during this slope session.

The 66" Pegasus Hawker Hurricane kit was taken off the "To Do" shelf the other day, opened and work has started in ernest. I wanted to push on with the wings so I could reinforce the wing joint at the same time as laminating the Rebel RG 65 project. The fuse is also making steady progress but a little less messy.
I carefully remove the veneer put aside for re-use and dust off my trusty Bosh to router out the wing servo apertures. Then using an old tent pole I carefully drill the conduit for the servo cable. Following that I used the same technique to recess the
Flap servo.

Rebel has been planked and faired. Those curves are all man and hand made without any form of software intervention or Can't Frigging Design ( CFD) assistance.

It's such a shame to see these once lovingly constructed, pristine models being left to rot. There's a Catalina, Leopard Moth, A4 Dutton perhaps a DH Vampire and Sunderland.
If you are of a sensitive disposition you'd better look away, what you are about to witness could be very disturbing.

This part of the build has got to be one of the most rewarding. With each plank the hull shape develops in front of you and you cant help but start imagining the completed model effortlessly gliding through the water.
The majority of the planking to the freeboard has been cut to taper from 5mm at the stern to10mm at the bow. Even though this design is slab sided and the freeboard could have been cut from a single sheet I chose to plank it due to the additional stiffness laminating achieves and also to reduce the likelihood of twisting by the alternate turning of each plank end to end. It's how they made the old wooden spars in the old days to stay relatively straight and strong.
When it comes to cutting the normal planks I cut the individual strips using two lengths of alloy angle, one placed on top of the other. It's quick and accurate.
