After the best part of nine months I finally got to maiden the Super Scorpion, the old engine hadn't been run for the best part of 8 years so it took 3 or 4 spins with the starter to get it going, there was a breeze of about 5 - 10 mph and she weathercocked into the breeze and was airborne in about 20 yards.
Definitely needs some downthrust on the engine but she needed 3 bleeps of right trim and then flew hands off.
The tank was a bit low and with no exhaust pressure she only 3/4 emptied the tank, still that was about a 15 minute flight.
I did a few loops and she spins beautifully.
3 flights and I called it a day.
Ishall change the 10x5 prop for a 12 x 4 and once that's in place adjust the downthrust.
I'm absolutely delighted with it, feed in full up and she stalls straight ahead with no wing drop.
My chum took some pix and as soon as he sends them to me I'll post them.
As you can see, I'm one happy bunny!

Flew the pulse again yesterday and today, the saito is becoming more run in with every tankful, had about 4 litres of 10% through it. The only downside is the crankcase breather is spewing out oil which makes its way back in the slipstream and gets into the r/c compartment, it also gets in between the wing joint and soaks the ribs so, my advice is really fuel proof the r/c compartment well and do the same with the root ribs of the wing halves, I'd recommend covering the root ribs with profilm to prevent the oil getting into the wing compartments ( the wing halves are not glued together but come apart for transit)
The final thing is the battery hatch which is retained by a dowel at the front and two magnets at the rear; these are definitely not up to the job and will not stay attached when the saito powers up, I've taped mine on but it really needs a small retaining catch at the rear.
Elvis has now left the building so I'm off to bed.

Flew it again today, but took the wheel pants off as we share the field with sheep, their, umm, carbon emissions litter the strip and the wheel pants had filled up with this c R ap.
Quite windy, about 18 -20 mph gusting to 26 so I was a bit apprehensive but, hey, she landed whilst going slightly backwards, this lovely plane is really growing on me and the saito 125 is Magnificent!!

Flew it today, after running in the saito 125 for 30 mins as per the instructions.
The model had balanced ever so slightly nose heavy on the cg position, so 3 clicks (bleeps?) of up sorted that, low rates are not very powerful, especially on aileron but she flies as slow as a slow thing and landings are a breeze.
The saito still has the needle 4 turns open, so is very rich but even in this condition a couple of vertical rolls are possible.
I can't speak too highly of the saito, it's turning a master classic 16 x 6 at just under 9000 t/m, god knows what it'll do when it's leaned out!!!
One of the wheel pants loosened up, I swore I put threadlock on it .
This plane sets really high standards for artfs, the only real bitch I've got is the thread sizes, we're all metric over here and finding allen keys to suit the stock bolts is a pain in the butt, so I'm swapping all the captive nuts for metric, but hey that doesn't take anything away from the plane it's fantastic!!!!!!!!

I've literally just glued the canopy on this a/c, the last job and it should be dried by the weekend.
This really is a super kit, I've put a saito 125 up front, there's not much ground clearance for a 16" prop!!!!
Couple of tips for other would be owners, put the switch in before the servos otherwise it's a pig of a job (even with lipstick ), the rudder and elevator are operated by wire pushrods in nylon tubes, defo not friction free; I heated the wire up with a hot air paint stripper and poked it up and down in each tube, now much less friction. Looking forward to flying it.
The Extra 300S has flown, the engine, a mk 1 Irvine 60 is far too noisy with the standard silencer so I'm having a mini quiet pipe made and that will be with me on the 16th.
Safe flying.

I've been busy and really lost track. The superscorpion is ready to fly but the wind has been blowing like mad.
I attach a couple or 3 piccies of the almost complete plane.
Since completing it I've also built a CMP extra 300s, to practice for when I complete my 1/4 scale Zlin, but ain't life strange, a guy made me an offer I couldn't refuse for the zlin and I sold it, buying a hangar 9 Pulse XT 60 and another hangar 9 sundowner 50 to sharpen me up. Hope it works.
On my building bench I currently have a goldberg cub which I'm building as the clipped wing version, a goldberg ultimate bipe a chris foss acrowot and now two hangar 9 artfs.
Should keep me busy for a few weeks.....

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

I ordered up a set of floats for the cardinal together with a fitting kit so I'll be able to fly off of wet grass, snow and water as well as dry land.
I still haven't fathomed out how to reduce the picture size so I can post pictures, when I do I'll flood the blog with them.

YES!!!!!!!!!!!!!! It flew, bit of a handful on take off as the engine is really too powerful for it and the reaction to torque and a slight crosswind was very interesting I almost ruined a perfectly good pair of jockeys!!!!!
Rolls were very barrelly, loops oval but the immelmanns were fantastic.
Not enough wind for the cardinal but I got my 1/5th scale piper cub up till the normally reliable saito deadsticked on me.
BTW the D7 took some hits on its last mission so I shall have to put some more workshop time in. I also got throuh about 2 litres of fuel.
See ya soon.

Batteries charged, glodrivers charged, 2 gallons of fresh fuel boy, am I ready and it's my youngest son's birthday party barbecue this weekend on Sunday and two of the kids are swimming in the Dover v Calais festival of sport Saturday, I give up........

Even if I could've gone flying it rained, it's been raining quite hard for most of the time for the last 8 1/2 hours, I hope the floats for the cardinal are in stock I think I'll need them...
Nothing done in the workshop, I have a man cold, which as every decent citizen on earth knows makes it mega times worse than anything a woman can get
I think I'll go and try to work out how to resize my digital photos that I have so I can show them off on here

Looks like it's a lovely flying day today, unfortunately the gods are against me, it's halfterm holiday for my kids, the wife has to go for a check up at the quacks so I have to hold the fort as if there's one thing my kids hate it's model flying.
Never mind I'll get on with some make do and mend to wile away the time.
See yuz later.
