I've roughed in one of the flaps to see how it works and where I can still measure. Balsa blocks were glued into the wing TE to provide a lot more support for the hinge. I may add some brass tube to re-enforce the gluing area. The jig worked well. The wing TE went as planned, the TE of the flap surface had a strip of wood clamped as a packing piece. this meant that the drill entered just at the LE bevelled edge, keeping the knuckle right on the hinge line.

Of course, may be a day or so, waiting for my orders. Also need to pick up my Robart drill jig from a mate.

Spoiler .... . . . . . . . .. . . . . . . . . . . . 4100?

I get wood sometimes!

I made a tiny sanding block for the ply pockets. Very easy to get the depth just right

While waiting for some bits to arrive, I might as well rough in the flaps. No servo reverse needed as Hitec and Align servos moves in opposite directions to the signal inputs. The pushrods are the old aileron rods. Horns were saved from a crashed model. Small ply plates face the horn bases top and bottom No going back now...

The RB 319 drill jig is a must

Yes, you’re correct Fowler flaps are probably not the correct term. I have the Robart jig for pin hinges, an excellent tool, also it’s worth getting the different size drill collars. I’ve done a few pictures to try and make my explanation more bearable. Where you want the centre of the hinge is marked by a line across the hinge line. The notch on the bottom of the jig keeps the holes the same distance from the edge. The centre is marked on the jig. After drilling the hinge is placed into the holes so that the pin is in line with the hinge line

After looking through other Rc forums (😷) I found a couple of useful tips. I made a small jig to get the pin hinge constant and in line. The small notch underneath will hopefully work to keep the hinge at a correct distance from the hinge line. I hope the hinges turn out like this below... I will need a bit of practice on a bit of scrap

How NORAD's Santa Tracker started...... "A local Sears store in Colorado Springs ran a dial Santa ad in 1955. However, the number was a misprint. Instead of listing the number for Sears' Santa hotline, it posted the number for the Continental Air Defense Command Center. On Christmas Eve 1955, Colonel Harry Shoup began receiving calls while working at NORAD from kids asking to speak with Santa Claus. Instead of telling the kids that they dialed the wrong number, Shoup said that he wasn't Santa Claus, but he could track him on radar. All night, Shoup and his team fielded calls, giving kids details about Santa's location as he and his reindeer flew through the sky to deliver gifts to children." This is how a tradition was born. NORAD opened its lines for Santa Tracking every year since.

Look what I got from my Lad for Christmas.....a triplane !

Keep death off the roads....drive on the pavement

Oh dear...and I thought it was going well. A bit of a panic moment. The green covering on the underside is stuck directly onto the fuselage. In my defence I tried everything to get every bit off. Doing the first thinned coat of thinned non shrinking dope the green decided to let go and smeared over the bottom of the fuselage. Some liberal applications of non bloom thinners has wiped 90% of it off, the rest has gone deep into the balsa grain that sits just behind the uc plate. Hopefully with the nylon a base coat of 2k paint it shouldn't be very noticeable, it’s on the bottom under the wing seat at least. Need to order some pin hinges and ca hinges, more dope, 3mm push rods. The rest should be in my junk drawers. I think I’ve got enough nylon.

Productive afternoon ripping the covering off, sanding and generally making a mess. The fuselage is interlocking ply sheets. Nice touch that a piece of hardwood in the vertical stabilizer I’m in two minds about putting a hatch in the front. I’ve not needed one up to now. Anyone think it’s needs a top hatch behind the engine?? Also programmed the radio for flap servos.

I recovered a small artf Wot4 years ago. I’m glad I did some of the balsa was almost see through it had been sanded that hard.

Well, my poor Wot4XL is nearly 10 years old. It’s had a hard life, been a test bed for a few engines and been the go to plane in the winter. The old thing has been the first thing to fly at a new venue as the handling and characteristics are so reliable. Now it’s time to see what all this abuse has done to the airframe and see how the general build has coped with the stress. I plan to strip the old tatty covering that’s now gradually peeling off the balsa and recover in white nylon and dope. As everything will be accessible I will re-hinge with Robart pin hinges and add flaps....because it’s mine and I can 😛. So what to begin with? Something easy like the wings. And for those who’ve always wanted to know what the build quality was like...here you go... The only thing that needs a minor repair is a loose wing tip

No flying again this weekend, heavy drizzle all day on Saturday However, got the club noise test done, fail safe and range check done on the big tiger moth It’s now 5 weeks without a flight😬

Three?

I began using Aspen 4 a few years back. Much longer shelf life than “ ordinary” petrol, more refined. Seems ok to me. More expensive though

Ours usually throw up on the clean laundry or the duvet 🤢🤮
