Got one of those Hatori tubes Don, but the cowl is so shallow that even with other elbows I doubt if it could be fitted.

Anyway, that is a long way off to worry about just yet.

Started to watch more of those videos and they are very informative indeed so far. Many possible pitfalls pointed out already and I am only on No. 6.

Now that I have the basic fus. structure together I realised that those T nuts should in fact be fitted from the underside since the u/c must bolt on from the inside! Much debonder required.

Some pics of the fus. ready to start covering. Added the parts to fill in the voids as per the videos and changed the front a little by widening the gap to accept a small tank.

Now looking at the tail, you can see a few glaring omissions regarding the laser cutting. I shall simply chop off the ears and glue the parts together.

The videos show the guy covering this without the sheeting but this is quality light balsa so I shall use it.

Got the fus. minus all wing fixings and cockpit done and ready for covering the initial parts and was looking forward to the videos of the wing construction, but alas they just jump to a completed wing so a waste of time.

The tail, elevators, fin and rudder may as well have been made from 1/4" sheet; at least this could be shaped a little instead of having very thick TE`s. After all, why use three parts when thirty will do. A bit like a dreaded Guillows kit where the c.a. weighs more than the wooden bits.

The wing has a drawing showing the rib positions but otherwise can be likened to a thousand part jigsaw puzzle without a picture to go by.

I bought six servos for the wing but when they arrived they were analogue MG, not my usual digis. Wondered why they were so cheap so got six slim wing servos which will make installation much simpler. Three of the others will be fine in the fus.

Now getting the ribs sorted out and ready for fitting after I have figured out what goes where and in which order.

Wish me luck.

OK, got two wing halves made up. More errors and things to watch out for, particularly fitting the hardwood piece W20 at the outset. I firstly pinned down the rear under spar ensuring that it was straight because everything else depends on this. Then W20 (there are also two other parts called W20!), slid the ribs over the carbon tube, added the top spar and the inner LE, pinned it all down and tack glued the lot with thin c.a. Added the hardwood ribs at the root and made up and fitted the tips. There is a small reference to W7-1 and W7-1 short. They look the same before removing from the sheet but they are not. Easily fixed.

You need to know which way to put the LE on as the pics. do not agree with each other, so before the above I made up the slats to ensure that the horn cutouts aligned correctly. These are quite tricky since you need to plane and sand two bits of square wood to the shape of a comma. Masking tape helped on the second one to prevent grooving the larger piece. Hindsight.

The front of the LE is W9-1 which was fine on the first half but the other one is actually marked W8.

Went over all joints with R/C Modellers` glue.

This is a really strong (and heavy) wing and I can see no need for a full span carbon tube.

Started to modify the servo mounts ready to fit but watch out because the drawing shows them one way round and the pic. of installed servos differently.

I still have a huge amount of unused bits. Next will be the wing centre sections.

 

It is fairly obvious that the manufacturer has not made up a production version of this otherwise these errors would have been picked up. Reminds me of my HK Lanc. which could not possibly fly as supplied but is actually quite good when modified.

This is one on my wish list Martin. Following with interest

Got mine from HK EU about £85 post free.

Looks like I am the only one to have sheeted the tail and fin.

Now playing around with how to fit the OS52. It will be angled so that the silencer will clear some u/c parts and will probably have to split the cowl horizontally so that it clears the cylinder head without too much more chopping about.

Have now done a lot more work on this. If anyone thinks that it is a slot together then simply add c.a. then think again. Even at the stage it is at now I still seem to have a multitude of parts which must be to do with the u/c.

The fus. has been covered, including the wing stubs prior to fitting. 184 tiny screws holding the glazing in place seemed to take forever. The motor has been squeezed in but I had to cut the cowl in half. It does not look too clever at the moment but it will have to do.

As you can see above, the tail and elevators do not match up so I added a couple of bits of wood. I really should have binned everything at the tail end and re made from 1/4" balsa: at least I could then have given them some proper shape.

Trying to find and cut out the hinge slots in the wing Solartex was also a tedious job. The bits of ribs where the slat hinges go keep breaking so I shall probably remove them all and replace with 2mm spacers between the glued in parts of the hinges which should make final assembly easier too. Getting the 2mm hinge screws fitted with minimal play should be interesting. Will most likely paint them black and assemble with a smear of petroleum jelly.

I shall bash on.

A bit more. Got the appendages fitted to one wing panel without actually gluing the pivot bolts. These needed careful adjustment to make them free without slop. I shall probably remake the horns because the supplied ones will most likely just fall off as in the Captain Rob video.

Also shaped the tail and elevator LE`s and got that lot covered.

After a disproportionate amount of effort I now have this thing as far as I intend to go before attempting to fly it.

I found it necessary to modify a great number of parts, mainly the control horns. I had to discard the supplied ones because they are nowhere near long enough and easily fall off anyway. You can see from the pics. that I needed to use a ball link on the tops of the ailerons because they cannot work if built as per plan. The holes in the centre parts of the hinges are far too large for 2mm bolts and caused lots of play so I bushed them with brass tubing - a long job. The tailwheel was discarded and substituted with a HK one.

Found that the Flying Legends example is in dark grey only so this suited me fine. The German crosses from HK are not scale but saved a lot of time.

The cg has turned out a tad rearwards with an empty tank but worth a try as it is. The motor has not been run for years so fingers crossed.

Some pics.

Anyone still thinking of building one of these I would say forget about it, and if you already have the kit then try to flog it to some mug!

You have a result though Martin, your perseverance shows through! What is the finished weight? It could turn out to be a decent flyer!

Well done Martin, at least you have a completed model. Still have a long way to go on my build which has a slightly larger wing span of around 86".

Tank has been constructed and the radio gear is now well tucked away under the cockpit floor.

Currently stuck on the wing struts as need something strong as it will be functional and will take the flight and landing loads.dsc01085 (medium).jpgdsc01087 (medium).jpg

Looks like you are onto a winner there with one that size Andy.

Mine is 2.38kg, about 5.16lb, rather more than they estimated as usual but should be fine.

I have left off the dangley bits as yet, also the tail supports because they would do nothing and just push the cg even more rearward. I have loads of laser cut bits left over and no clue as to what they were intended for.

A slight problem. Even though I thought that I had set everything up ready to go, when I came to final assembly and testing, the left LE and flaps went the wrong way and the travel was a mile out. Obviously my error and in future must do this before I have a celebratory beer.

TN Concorde plan is already on the building board for scrutiny: fans, esc`s and most of the wood to hand.
