Thanks to all who like this build!

@ malakiblunt
The bottoms of the pylons are reinforced at the whole length with a strip of 0,3x5mm glas-fibre. To be able to add several "cargo pods" each pylon got two 0,1x10x10 steel plates folded around the glas-fibre strips.
The "heavy" magnets are mounted onto the top of the cargo - the main advantage is, if the plane comes out too heavy the magnets stay on the ground . I used the same principle at my SU-22 and YAK-130.

A pic to explain how the pylons are build and a 2nd pic of a possible cargo-configuration:

Sorry for the lack of postings for so long. In fact I was able to invest only a couple of hours into the build during the last six weeks or so because there is a lot to do at work.
But I found time to carve the inner and outer parts of the engine-nacelles tail sections this weekend. Also carved and sanded the cutouts for the nozzles and prepared abused pudding-cups to work as nozzles. Unfortunately they are way to short and very soft, so im tinkering around with PVC-sheets for a better solution. Not much progress to see so no pics at the moment - but I keep on working on her!

...finished the nozzles and the tail sections of the engine-nacceles. Also made the servo-pushrods, glued in the servos, finished the servo-harness and programmed the TX.

But I guess I fried one ESC during programming

Finally checked the CG: and once again I have built a nose-heavy bird! The CG is about 100mm (4") too far forward with the planned 3s-5000mAh accu. So I have to redesign the accu-compartment
Same happend to my Nemesis and the Henschel HS-129 - but I guess its much better to be nose- than tail-heavy

...something between these extremes would be nice

Yesterday I replaced the controlers by two new HK Super simple 50/60 ones and soldered a new power-harness: both EDFs are running smooth up to full power now (balanced them before - as good as possible - not easy to do so at this units!)

Now some little cosmetics and the modification of the accu-compartment are left to do and then I finally can start to paint her. I will add panel lines before the paintjob as I did with the Henschel - came out quite well

...she flew pretty well but a bit underpowered - not because of the EDF's but weak, old 20C-accus.

I have "kind of" plans: a 3view including cross-sections and templates for most of the parts. But as you can see on my posted pctures there is a lot of scarfing and sanding

I will have a look on my old Laptop whether i can find these "plans" and convert them into pdf's after vacation (till end of september)

Greetings from bavaria
