I was going to write here she is ready to cover when I noticed, whilst uploading the images, that the subfin was missing. Now what in heavens name have I done with that?

The motor in the photo is one of the original OS 40 FS pre surpass days, not the most powerful engine in the world but adequate for this model. I have a bnib os 26 fs and I just may stick that in there.

The covering plan is to cover the fuselage with a violet coloured lightex from world models then the wings tail plane, fin and rudder with white micafilm. The leading edge sheeting on the wing will then be covered with remnants from the lightex as will a similar pattern on the tail bits.
All this will happen before my birthday in early august, I hope....

I was reading back thru the blogs and there were several sets on setting up glo engines.
I converted over to 4 strokes last year and now operate OS - 3 x 26fs, 1 40 fs and 1 52 fs, Saito 2 62a and 3 82a plus 1 125a that I have yet to run.
I also have two lasers, a 70 and an 80 but apart from the main needle these don't need setting up.
Starting with a new engine I organise several things. 1st run the engine in as per the instructions, when there's about an hour on the engine take it out of the airframe and mount it on the bench. The directions given here are for the saitos and OS 52, the 40 and the 26s have an airbleed carb that generally doesn't need setting up; if they do the airbleed needle is opened (turned out) to lean it and in to richen.
2nd make sure you've got new fuel, your glostart is fully charged and the plug works, I only use OS F and Saito plugs now, you get what you pay for.
3rd The engine is now in the engine mount on the bench, tank is set up so the centre is in line with the throttle barrel and you've picked the prop for the plane you're going to use it in.
4th start the engine and set the top end using a tachometer, then back off the main needle 300 - 400 rpm. I generally do this bit with the tank about a quarter full.
5th stop the engine. Now close the IDLE needle until it JUST closes, don't over do it.
6th disconnect the exhaust pressure line and put a piece of clean silicon tube on, remember the tank is only a quarter full and the exhaust...Continue Reading

Very little to blog to date, my super scorpion is coming on, fus, tail, fin and one half of the wing is built just the other half to build, join with two ply joiners, sheet the underside and she's ready to cover.
I've got one sheet of white coverite micafilm left for the wings, a roll of world models lightex in a fetching shade of violet for the fus and for trim on the wings and tail set and she should be ready (at my snail's pace) for august.
Really looking forward to getting this one airborne, I find the design really attractive and can't wait to see the sun thru the covering!
Didn't go flying this weekend, too windy, should get out on Tuesday when I'll give the Falcon another airing.
I've decided to sell the "Windy Ain't It" as I've now done my thing with it and someone else can enjoy the unusual lines whilst it flies.
I have to resolder the u/c wires on my junior 60 before it can fly, it'll be a good move as it handles windy days much better than you'd expect it too and I haven't flown it for a couple of years. It was originally powered by a 30 fourstroke, one of the OS clones. This wore out so quickly (about 3 hours airtime) due to the piston ring being made of boiled pasta but I sold the engine on at the 2004 nationals and fitted an OS 26 fs to the airframe, this has now got about 10 hours + on it and gets better and better, turning a 10x4 apc at phenomenal revs on 10% nitro. The 26 FS in the windy aint it turns a 10x5 apc about 400 rpm less than it so that won't be sold with the airframe, may refit it in my Black Magic where it's already had about 5 hours use so should nearly be run in with the hour it's had in the "w.a.i.".
Once I flown that one a bit I'll sell it on too as, for some reason, I just can't get on with it despite it being on my all time wish list.
I'll pack up for now.

Just a few pictures of the last resting place of a great uncle of mine, who died of his wounds at this site. The village is Dranoutre in Belgium which is within rifleshot of Ypres.
My gt uncle died in march 1915 aged 19 when dranoutre was a hospital camp so he's buried in the churchyard of the village. There are several massive military cemeteries all around the village where the soldiers, german, british, canadian, Indian, Australian and American who were killed in one of the several battles round Ypres right up until the last days of WW1.
I didn't discover my uncle existed until the early part of last year and tracking him down was a long task. One of his brothers used to come over to pay his homage from his hotel on the yukon trail up til the early fifties, I go over every year now, silly me it's just to let him know there's still someone out there who cares; I guess you'll know what I mean.
The church is absolutely immaculate even though it was destryed in WW2, there is also the last resting place of a belgian ace, buried beneath the tail of his Mk 5 Spitfire.
The graves, as you can see, are kept in impeccable condition by the wargraves commision and also by the local inhabitants who show their gratitude every year on November 11th at 11.00 hours when, on most of the major cemeteries, there is a moving remembrance service and the last post is played. It really is moving. If any of you have relatives buried over there you can take a crumb of comfort in that they are revered by the locals and many Brits who go there to pay their respects.

I lost a post as I was trying to upload some pix, so I'll try again.
My two youngest bought me a father's day gift yesterday, it was quite a surprise I can tell you. An even bigger surprise was in store, they asked me for the money to pay for it!
Yesterday was a lovely day for flying and I had my old Ben Shereshaw Falcon out, powered by a laser 70 4 stroke it was the first time I'd flown it for nearly 2 or 3 years. There were some really BIG thermals around, equally there were even BIGGER downdrafts any way I floated around for half an hour and even called a landing and the big old bird plonked down smack in the centre of the strip, really pleased with that, my Windy ain't it had problems with the engine so I took it home and discovered a split in the exhaust pressure line, sorted the engine and control and, after dinner, went back up the flying field for the last hour of daylight.
She went off dead straight and the 5 degrees of downthrust I added aren't quite enough. Took her up till she specked out, brought her down for some lovely low and slow passes then a few loops, try what I could I couldn't get a roll out of it, the rudder is way too small.
Specked her out again and 13 minutes into the flight the engine spluttered and died, not bad for a 2 ounce tank eh? the OS 26 fs is really frugal. 10 minutes later she crossed the threshold and once again smack down on the spot. Absolutely delighted with this plane's performance; it's taken me off and on 7 years or more to get to this stage so I guess I'll retire it after this season, as I really used it as a challenge from my youth, it certainly brought out the rose tinted spectacles .
I'll try, once again, to add some pics, I'll add the descriptors if I'm successful!!!!
Well, the yellow and blue one is the "Windy Ain't It" and the other is a semiscale Fokker D7 that I've commented on elsewhere. The former has to be 20 years old and the fokker is about 10 years old.

With some trepidation I re-maidened the cardinal after its tail graft. The Irvine 61 was extremely powerful, quite surprised me as it had much more vertical performance than the saito 82 it replaced.
The C of G was spot on as was the lateral balance and it didn't skew out of loops, rolls were getting more twinkle like and the "sit" of the model whilst flying was very scale like.
There was a 20 knot wind blowing and into the teeth of this wind it flew forwards at the rather high tickover I'd set. Like a complete idiot I reduced the tickover until it barely made headway, and decided to come in as I'd been stooging around for about ten minutes, as you do, opened the throttle and it stuttered and died. I came around downwind and tried to turn back onto the strip and she literally fell out of the sky from about 5 feet altitude.
Broke the prop and a the wing mounting bolts but it's easily repairable.
I'm still trying to kick my own butt for reducing the tickover, but it had an enya no.3 inthere and I felt confident that would stay alight. Ho Hum .

Not much in the way of modelling stuff, I've been watching the Manx TT on the tv, god those guys need a medal just for being there and that's just the spectators, the riders are absolutely fantastic but how they get their gonads into their leathers is anybody's guess , the guy that won the senior TT has now won it as many times as Mike Hailwood and has only to win it 3 times more (I think) to equal the 17 times of the most frequent winner who, unfortunately, was killed a few years back.
Well worth watching.

This is one of my favourite sports planes, it's a design by a british icon that first came out in the 80s and has been developed ever since. I think it's loosely based on a Zlin Akrobat and comes as a quick build kit with foam veneered wings of about 58" span.
Recommended engines are for 40 to 60ish 2 strokes and up to 91 ish 4 strokes.
I've flown my first one on every thing from an OS 46 fx, magnum 61 4 stroke, saito 82 and the most ballistic of all with a yamada 45 2 stroke with a mini-pipe.
I knocked the wings off in the long grass the other week and I've misplaced the broken wing bolt mount so, as the fuselage is a bit tired after 4 repair jobs on it, I dragged the spare kit out of the loft and I'll put that together over the next few weeks.
It'll give me an opportunity to try glass cloth and epoxy on the wings as the veneer is prone to lift in our ever changing weather conditions over here, though I'm pleased to say the blanks haven't suffered in the last 4 years in my loft.
I intend to use a saito 82 as prime mover as it's just the right weight with bags of grunt on 10% fuel and powers the plane with good authority, though I do have a saito 125 sitting round doing nothing that is of similar weight to an early OS 90 fs, I wonder
