Lovely weather and a busy week from a stroll to the shops via the coast path to walking up Lord Hereford's knob for a bit of slope soaring. Not forgetting a little journey to the Midlands for a weekends racing IOM's in the company of World, European and National champions. And tomorrow it's the Mumbles Y.C's Open Meeting where Harry and I will race the 200 tomorrow and I'll be racing a Dart 18 on Sunday in preparation for the up coming Europeans....Continue Reading

Last Friday I arrived home to find a 66" Hawker Hurricane MK1 had made a safe arrival. This is a Pegasus kit and I'm quite impressed. The kit is designed for IC 2/4 stroke engines but I'm sure it will soar satisfactory. On first impressions the only thing which lets it down slightly is that there is no wing to fuselage fairing, but details and sections are on the plan should you wish to make and add them. I guess this is one reason why the kit is so reasonably priced at 104 brand new. This particular kit is 'New In Box' (NIB) second hand and I paid 85 which included an upgraded 14 GRP cowl. I arranged the courier (YODEL) at a reasonable cost of 6.90 for their 48hr service and was tempted to insure the parcel to take the total cost to just under 11. So hopefully all in all a fair price for a fair kit. Now I just need to get motivated and complete the Sorrento. Outer wings are the hold up as the fuse and tail feathers are practically all done bar the covering.

Some footage from my local slope. A little more lift would have been helpful but overall it was still an enjoyable afternoons cruising.

Last Sunday both my recent 2014 homebrew IOM's were on the water during a 'Try a Sail day'. The wind was from the North West and proved very testing in its own rights with big holes and big gusts. Perhaps 97 has a little too much backstay tension identified by the diagonal crease in the lower half of the main.

15mph South Westerly and Fred and Hammer take off from Hunts, their home turf so to speak! There was just enough lift for Fred the ME 109 which is strictly an I.C model so the wing section certainly isn't ideal for anything less than a moderate breeze. However, she felt a little more stable and was less likely to tip stall with a little reflex dialled into into the ailerons, probably due to the wash out effect but the compromise was less lift which occasionally was a little scary.
The Hammer on the other hand revelled in the conditions and appreciated an additional 200g of ballast. This was the first time since her construction that I had flown her with ballast and she could probably take another 200g as the difference was a better, more steady platform which flew with a positive more purposeful manner.

Met Mark and Marcel for a few hours of slope therapy at the Ice Cream slope, The Bwlch, South Wales. The Sun shone but the lift was a bit intermittent to begin with. After a short while the wind started to back and the legendary Bwlch lift kicked in and the battle commenced! I took the trees with me in the form of a 43" ME 109 PSS and a slightly modified Phase 6. Local Mark shredded rather than soared with his Cappucino and Race 1. Whilst Marcel from Switzerland was ripping his homemade GRP Jart, practically turning it inside out. The Bwlch is a big place and the Jart and Cappucino were just eating up the sky.

Vertex has been sailed and raced. First impressions are promising, she pointed very well and by comparison wasn't at all sluggish on the runs which is usually my slowest point of sailing. The longitudinal trim requires further tuning as the stern was a little high whilst the bow was too low. I was hoping I had alleviated or at least improved this scenario by moving the rig and fin further aft from the VTX's but the placement of the corrector weight will also have to come into play and for starters will be moved just in front of the mast post. Overall, after 10 races I finished in second place but first out of the non handicappers. The skipper who came first is allowed a 20sec head start and he won 5 races. I think I won 3. This week I'll have a little break from the bench, try and get some flying in and start Vertex's registration and measurement process.

Fitted the winch, continuous loop, rudder servo, pot and bow bumper this evening. Can't wait to sail her. The new winch is also better than expected in respect to speed and accurate, repeated end point positions. At the moment I'm using a spring to keep the tension in the loop but might change to a self tensioning drum in the future. I'll also have to seriously consider replacing the Futaba 3003 rudder servo as there's just a little bit too much slop. But to be fair with my skill level the rudder servo is the least of my problems :>0

Recently I have sanded, resined, sanded and then sanded some more! I have also fitted the rudder tube, main sheet post, mast ram tube, made the rudder control rod and through deck fairleads for the jib sheet. Yesterday I managed to give the hull it's first coat of 2K paint. It will need at least one more coat but hopefully that should do the job.
Bleu Clair (light blue). I'm very happy with the colour which I mixed using the white from the Edge, my last IOM build and the navy from the BOR which was prior to the Edge. It's therefore pretty unique! I'm aiming to just add water and maiden her this Sunday.

Today a fishing competition was keeping us from our normal racing venue. So by prior arrangement we visited a neighbouring Clubs lake. This is no ordinary lake! It is man made and is the smaller of two which were quarried to obtain hardcore for the local main road. However, at 400m x 200m it is plenty big enough. The lake is just South of Glyn Neath and nestles almost in the centre of the Neath Valley, South Wales. It's high forest covered sloping sides gently persuade the wind to blow from a Southerly direction with subtle differences in both direction and strength to provide sublime RC yacht racing. I would liken it to the infamous Italian sailing venues of lake Como rather than Garda as the strong gusts are to be found more up the centre of the lake rather than the sides but I'm sure this could change if the wind was from a more Westerly direction.
What would normally be for us a Top Suit conditions at our normal venue and a religious day's racing of praying for continual breeze whilst avoiding the wholly areas (Pun intended) around the shallows and shadows of the surrounding tree's turned out to be perfect Working Suit conditions with high speeds and huge 150m + legs. We have another two visits to Glyn Neath booked this year and I for one can't wait till the next visit.

Yesterday the foredeck was glued to the hull. I used Gorilla glue on the inwhales and Arildite on the jib thing! both to the foredeck and to the bottom of the hull. This helps to transfer the loads from the rig the hull. Today I have made the winch and rudder servo trays. It's surprising how long it takes but again accuracy is all important as the trays help to distribute the sideways loads between the rig, hull and fin.
I also think it is beneficial and makes a lot of sense to me to keep as much weight as possible close to the yachts CoG / CoB. Therefore, I find it most strange why the Britpop for example has the winch positioned in front of the mast (admittedly quite low in the hull) and the rudder servo behind the mainsheet post positioned quite high in the hull. This distance between the two is fairly large compared to the LWL. When all designers are looking for that extra edge surely small gains add up to bigger advantages so even moving the rudder servo closer to the CoG and lower to the CoB could be beneficial? Keeping the weight close to the yachts CoG prevents hobby horsing, nodding dog syndrome or just put plain & simple the rig pitching the wind out of the sails. If you imagine a sea-saw it rocks up and down much longer with weight on the ends producing the momentum compared to an empty sea-saw.
So with this in mind I have tried to place the control servos as low and as close to the CoG'B as possible.

Steady but slow progress is being maintained with the Vertex build. We've almost rounded the last mark and should be on the last beat and painting by the end of the week.
So, whats taken so long? The liteply inwhales have been fitted. 5mm wide at the aft end, tapering at the midships to take in account of the shroud plates and 10mm at the joint between the hull and foredeck. The foredeck bulkhead has been cut and fitted along with the kicker and pot wells. The fin and mast case and jib thing! rig tension/hull stiffener have been manufactured. And all balsa and ply parts have received 2c'ts of West resin.

2 channel soaring is so therapeutic, it has to be done once in a while in order to cleanse the slope soul of all those botched aerobatic tricks and misfortunes! And there's no better time to do it than on a Sunny, warm Friday afternoon in 8-10mph of sea breeze.

No building today but the postman delivered my new winch which was ordered last Friday so that was very good service. I'm sure the Titan will prove very trust worthy and does all that is required of it. Plus it'll take a self tensioning 32mm drum, weighs 137g and is made in Britain.
Then this evening Harry and I went for a play in the Bay on our Phil Morrison designed RS 200 which is an absolutely fabulous sailing dinghy.

Over the weekend I only managed to complete the fore deck plug and give it two coats of wax. Today I made a bit more progress and practically completed the foredeck shell. Whilst the resin was running I also reinforced the hull along the chine as it felt a bit vulnerable and then the midship, fin and mast area.
Now the sundry bits and bobs start to get a bit smaller but the time to do them seems to take a lot longer as the emphasis is on accuracy.

It's been a very long time 8-9months since we last raced with the B rigs but the wait was worth it. What a blast and the Edge didn't let the side down with 8 bullets from 10 races. I retired in the seventh race when the jib sheet got tangled around the clew which looks like an impossible feat on dry land but that's sailing and again the jib sheet snagged on something during the first leeward mark rounding of the tenth race. This opened the door for Nigel to glide past taking the lead whilst I was left to faff about which eventually released the sheet. With a 15m lead there was little chance of me catching him up so I had to settle for a second.
Unfortunately skipper numbers were slightly down on the usual and the results will be littered with retirements due to poor rig choice, breakages and in Doug's case an attraction to the only tree obstruction in the whole lake!

1000mm x 160mm x 18mm MDF, contact adhesive, jig saw, electric plane, smoothing plane, sand paper and a couple of hours later the fore deck plug is ready to be varnished prior to use. First I cut the MDF in half and cut and sanded one piece to the shape of the hull shape. The other piece was cut slightly larger as I used contact adhesive to glue the two halves together, with contact adhesive you only get one chance hence making one larger allowed for slight misalignment.
Once the halves were joined together I marked the depth which worked out 36mm at the mast and 18mm at the bow, hence the sandwich construction.
The work then progressed outside due to the dust as a fair bit of planing was about to take place.
I'm still of the mind that a high flat foredeck is beneficial compared to lower decks with prominent spines, ridges running up the centre. Keeping the jib boom close to deck helps prevent the wind from cheating underneath the sail and the flatness also reduces rotar and vortexes on the leeward side. There is a slight weight draw back but is all about compromises.

Vertex's hull was faired last night and I also fitted the pre FG'd 2mm liteply transom and bow. As I've said before I always try and use up any spare resin to laminate offcuts of balsa sheet or liteply as it always comes in handy during this type of composite build.
The fairing shaved (sanded) off a staggering 14grams, this was very pleasing and now in her current state the hull weighs 220g or 7.75 oz. Next I plan to make the fore deck plug from 18mm MDF and retrieve the mast fin box out of the VTX as I hope to fit it in the Vertex

That's the current weight of theVertex hull when it came off the plug. It's been an interesting past few hours of this build. Last night I thought I had prepared the hull for it's last flow coat of resin. So this morning I mixed the usual 18ml of West Systems resin which works out just the right amount to cover the hull but I had a couple of millilitres left over. Not a problem as I normally use it up on spare sheets to make various parts. However, after returning home from work a quarter of the hull where I first started applying the resin was like an orange peel in texture. The remainder of the hull was looking very good. I was a bit gutted but life and especially modelling is full of ups and downs. As the resin was still tacky I thought I'd give the hull another filler coat. Another mix was soon ready but my favourite brush was still damp from being washed. A substitute brush was found but the resin was going on pretty thick so an additional mix was required to completely finish the hull. I cut some FG ready and waxed my kicker well plug to use up the excess resin so not much harm done.
The hull received this additional and un planned flow coat of resin but as a consequence of the different brush causing more than usual amount of resin being required. Or the first coat of the day not having cured quite enough a number of small ripples were apparent along the hull and will require some special sanding treatment. Oh well, I'm quite use to sanding.
This evening after a little bit of persuasion the hull released itself from the plug and like a new born went straight onto the scales. 223 grams is a respectable light weight but only 60 or so grams lighter than one of my balsa cored hulls which are probably a lot stiffer.
