Hi all! Well, this is the start of my build thread for a mk iid Hurricane for the PSS mass build. I should come clean early, and mention that the parts I'm starting from are already well under way - I have the bits of the beta build that Phil and Matt put together to prove out kits, and fixed so many problems from.

So basically, mine might not look like yours!

I've gone for the mk iid with underslung 40mm cannon, as I think that looks far more evil. They will dropped before landing either via eflight release mechanisms (if space allows), or a pin-and-latch system if it doesn't. I can then also fit a couple of 3D printed 250lb bombs for the bombing comps too.

Here are a few more pictures for inspiration, actual model progress shots to follow laugh

Onwards!

A quick check at lunchtime revealed that the wing is too thin for the e-flight release units, so an alternative will be drawn up today on SolidWorks that will utilise a single 9g or less servo to release the payloads.

Oh, found an actual real-life picture of JV-Z on t'internet:

Just goes to show how little you should trust the plastic kit bashers - their camo positioning is all wrong, oops!

Great choice Andy, I hope you will be mimicking the exhaust plume stain on yours!

Also following.

Did you see my gentle request for gun parts on 3D printing for us none printer owning chaps?

With a monetary contribution to your dog food fund of course?

Ooh, sorry Pete didn't see. I have also drawn up the reflector holders for the landing lights, and some 250lb bombs. Will do the guns next.

Some work at last on the mk IId.

Nose blocked up and filled, ready for final sanding to shape :

20180607_191050.jpg

Top of the fus, cut to a straight line. Just getting ready to install another snake here :

20180607_191103.jpg

A slight bow in the sides - this will be fixed with a sub former :

20180607_191108.jpg

LE's and most of the TE's - well, the false ones anyway - glued up :

20180607_192359.jpg

I make no apologies for the mess of the bench - it's like a Hawker factory in there at the moment, with the Hurricane, Sea Hawk and Typhoon all under construction, as well as glass work on the C17. Phew!

Good to see some progress here Andy - similar state to my airframe now too after my holiday break... we must all get pedalling - it will soon be September! thumbs up

Should be easy enough from here - there's not a lot of aircraft in this, thankfully.

Right then, so the addition of a web (as per Dirk and Harry) to allow the joiner some purchase, was added :

20180608_213459.jpg

Here are some fus mods to take the extra snake, and a sub former to stop the bowing of the sides at the top :

20180609_122315.jpg

The other tray :

20180609_123604.jpg

I added the top sheet, then gave her a good first pass with the hand plane and permagrit blocks :

20180609_171951.jpg

And now the extended inlet / filter housing. Sketched up on the plan, then transferred to lite ply :

20180609_224535.jpg

Slots marked up then cut into the chin :

20180609_224542.jpg

Test fit. Yep, GEFTS! (Good Enough For The Slope) :

20180609_224641.jpg

Liteply blocked up with 1/2" sheet, ready for carving and adding onto the fus tomorrow :

Looks like you may have the same problem as me Andy - fitting the cooler to a 3D curve - wish I hadn't rounded mine off.

To be fair Pete - if you had done it the other way, I'm sure it wouldn't have looked right - the air filter was an 'add-on' to the full-size original nose profile so what you and Andy have done will produce the shape more accurately IMO.

They're only slope soarers guys, it's not the WJM :D plenty of car body filler to the rescue I think.

Some carving, glue, and a touch of lightweight filler later, the intake is done. Just needs to dry, then a quick tickle with 800 grit to smooth things out

bit more tinkering with JV-Z these past few days.

40mm cannon pods - these started off as liteply centre sections, a shape drawn up from various views of the items on t'internet :

20180620_191914.jpg

These were then blocked with 1/2" medium sheet and wood glue. Clamped up, then left to dry:

20180620_192217.jpg

These were then planed and sanded to shape, and carbon tubes inserted to the approximate length of the real thing :

20180621_214214.jpg

The good lady wife thought I was building a small pod and boom glider - close to it I think!

The tip panels have had LE's added, and ready to be joined up to the centre. For the best bond, I used Gorilla wood glue, and added a triangular piece of balsa to bond the joiner to the bottom skin :

20180625_125132.jpg

Other panel next, then I can skin the centre section.

Dont worry, it's still moving along! laugh

Centre panel skin on, tips joined, TE blocks being glued on with torque rods:

20180710_125059.jpg

Some detail on the rudder (ribs and nav light):

20180707_191915.jpg

Start of the wing fillet in 64th ply. I was going to do this in foam, but decided on all-wood:

20180711_225649.jpg

Done! Soft balsa front and rear, blended in:

Well, I started the glassing last night, and all went well. With any luck I'll get the glassing complete this week and be in primer by the weekend.

I'm sorting a few extra scale details in between epoxy curing, the first of which is a tail wheel. I drew this up in Solidworks, then printed it on my old faithful Up Plus.

20180720_095535.jpg

Finished piece that needs a bit of tidying up before paint :

20180722_092751.jpg

I'll attach this with either a small magnet on the top, or a press fit into a carbon tube in the fus.

Lots of progress this past 2 weeks - wing and fuselage fully glassed and in primer, now it's time to fit her out and do some detailing.

Aerial masts and nose 'umps added:

20180812_192403.jpg

Aileron servos mounted:

20180812_182510.jpg

Some more printed parts - this time the exhaust stacks to my own design:

img-20180811-wa0015.jpg

Gun pods and radiator magnetised mounts final gluing up:

img-20180812-wa0008.jpeg

Next up - cockpit fit out, some more detailing, then final paint. I might just make it!

Looking good Andy.

How many magnets would you recommend for attaching the radiator? Hoping two will suffice.
