Fouga Magister and Ilyushin IL102 build progress

Firstly, the Fouga.  I have made up a small servo tray that will carry both mid-sized servos for the vee-tail (Corona 339HV - metal geared, digital, high voltage capable), which will be glued to the fuselage floor.  A long thin plate is screwed in over this to hold them both in the bracket.  I glued and glassed in the final former last night, so the fuselage is nearly done.

I have decided to change the way the wing is constructed on the IL102.  Instead of adding more foam for a centre section, I have decided to use the centre tray as an integral part, and add a second shear web / spar made of 1/16th inch birch ply.  This whole assembly can then hold 3 servos comfortably (2x aileron / 1x bomb drop), and be covered easily as it is now.

So that was a dry-fit, parts have now started to be glued together :

I also ordered up a nose light for the Fouga yesterday, along with all 5 landing lights for the C17, as well as more servos and LiFe batteries for the new builds.  Phew!

Fouga Magister build - wings are on

Just a very short update, but here she is with the wings on.  Is that 6 days since she arrived?  I think it is.  Now the wings are on the spar, I can do the last bits of glueing on the fuselage - F4 with the vee tail wire supports, and the ABS finisher on the back of the fuselage.

Fouga Magister build - overall progress

This has build has really gone together quick, and so it should with only a few formers to glue in, foam surfaces to cap off...and that's about it!

F1, F2 and F3 now glassed in, along with the wing joiner tube :

Cockpit floor shaped up - it's a biggie!

Wing LE, TE, tips and servo boxes all glued in and sanded.  Final fill stage started, and wing end caps to add, then these are ready for covering :

I want to take my time over the cockpit install, as it is large, but I have about 4 hours of building left in this airframe, then covering / spraying / finishing.  Very happy!

Ilyushin IL-102 build - wing veneer and engines

Last night, I set the wings in their beds with the poplar veneer attached by a thin skim of Gorilla Glue.  This morning I pulled them from the beds, gave them a quick sand, and hey presto!  Two panels ready for LE and TE's.

The engine pods have now had their final shaping, and a little light filling where required due to dings and scrapes from handling.  Here they are on the fuselage for a quick dummy run.

And the engines on their own, ready for the centres to be cut out on the fretsaw.

Ilyushin IL-102 build - wing spar

I Gorilla glued in the main spar to both wing panels this morning, and by lunch, the glue had done its stuff.

Nice bond
I had already put the masking tape down to protect the foam from any spillage, so it was sanding time.  A quick blitz with the big Permagrit, then down to a rubber block with fine on it, and we're just about there.

Once I knock the glue back on the other panel tonight, I will get the veneer onto them which I have already cut to shape and prepped.  With a bit of luck I'll get the centre section done and veneered too, then we're a lot closer to getting things complete.

Ilyushin IL-102 build - wings and engines

Last night the Good Lady Wife and I cut the wings for the '102, here they are on the bench after being cleaned up :

Stubby little things aren't they?  Don't forget they are missing their TE's, LE's, and some quite chunky tips with down-trurns, just like the A10.  I sanded a spar slot into the underside of the wing for a spruce spar that is 1/4" wide by 3/8" deep :

The only thing left to do here is to make the parallel chord centre section, then things can start being glued together.  

I have started to shape the engine intakes this afternoon whilst the exhaust sections dry :

New project - Fouga Magister for PSS

It's been a long while since I've actually bought a kit to build, but I've pulled the trigger on one of the best - a Fouga Magister from Island models.

Picture ruthlessly stolen from the PSSA Online website

My kit should now be winging it's way to me, so I've been looking at colour schemes of course!  I quite fancy either a Luftwaffe trainer scheme, or D-ICFF which is privately owned now and sports a simple but effective scheme.


Or this?

I'm really looking forward to this one, they just look so right in the air.

Ilyushin IL-102 build - fuselage continues

I veneered the engine nacelles at the weekend, and prepped them to have the airfoil section cut out too.  Unfortunately I didn't get around to cutting the wings as garden DIY was in order due to it being a nice weekend.  Next up for these is the addition of the intake and exhaust sections.  These will be glassed off of the aircraft for ease of access, then glued up with a spacer plate to offset them out a touch, as per full size.

I've stuck a doubled-up 3mm liteply former in the front of the fuselage to accept the wing dowel too.  I'm pretty close to sealing up the fuselage now and giving her a first sanding.

I've sorted another new airframe too - of one of the most (IMHO) attractive jet trainers ever made.  More on that when she lands!

Ilyushin IL-102 build - fuselage modifications

After much ruminating, I decided a single piece wing will do the job.  This means that there will be the traditional 2 dowels for location at the front, along with a nylon bolt or two at the rear.  This also means that there will be no servo connections on show, which is not only good for looks, but for airframe efficiency too.

First stage, cut out the wing seat and reinforce with hard 3/16" balsa.  This is wood-glued into the sides and clamped :

In the background you can also see the tailplane - now shaped - and glued together at the required angle (66mm dihedral under 1 tip).

As the wing is more-or-less mid-mounted, I will also need to have a tray mounted to the underside of the wing that will be come away with it when dis-mounted.  It's a nice snug fit at the moment, and here you can see it pushed back onto the fuselage with some markings on it :

Yes, two SLEC bomb releases of course!  The '102 is a ground attack and CAS aircraft, so she will need to drop some ordnance.  Here the tray has been marked and slotted to hold the bombs.  These will be driven by a single servo in a staggered release pattern.

A weekend at home beckons, so other than a bit of DIY getting in the way, the wings shall be cut!

Ilyushin IL-102 build - fuselage and engines

I used the balsa end plates as guides, so that Shona and I could run the hot wire around them.  After a quick lick of the Permagrit block, they looked like this :

That's just gently placed alongside the fuselage, with the tail feathers pinned in place too.

My next big decision is on the wing - whether to make it a one piece wing (making quite a big cut-out into the bottom of the intakes and fuselage), or plug-in onto a spar (increasing weight and alignment complexity).

I have also noticed from looking at pictures this morning that the rear decking taper should be a lot sharper that what I have - easy to put right at this stage thankfully!
