Thread: New Years Eve 2018 / New Years Day 2019 PSSA Fly-In

Hi All, I'm in ... both days if weather is on our side! Gt Orme or Bosley Cloud fine for me.

Thread: Using Ammonia.
28/11/2018 10:39:29

Have a look at the PSSA mass build Hurricane thread, ammonia is used very successfully to achieve some of the shapes in balsa sheet and in longerons.

Here are some things I would recommend:

Wear disposable gloves and use in a well ventilated area, or create an airflow using an electric fan

The fumes are powerfully strong - especially directly above any container the ammonia is in, if available wear a face mask/ or painting style respirator, keeping your nose out of the vapours!

Use neat and brush liberally over the area required.

Whilst wet- jig or clamp the material into the final shape required

Allow to dry thoroughly ( typically 30 mins plus, depending on surrounding air temperature)

Glue into situ, brushes etc can be cleaned as normal

Once dried, where the ammonia has been brushed in will be indicated by a faint yellow stain in the balsa

Sounds complex but its quite straightforward and you can get the balsa to comply to surprisingly contorted shapes.

Hope this helps.

Well done Peter, lovely to hear that your Cranberry is successfully maidened. Sounds like it didnt need much taming - trim wise.

Hi Alan, the Hurricane's looking good. Just to echo Dirk's comment - keep pushing along - your nearly done anyway!

Hi All, Just to add to the above post, still on a high from yesterday, what a great day!

A great event and brilliant to see so many Hurricanes on display in many variants and guises and then see them successfully maidened (20 in all?). It was also a great PSS day in general, with many other impressive models getting an airing.

Just to say a big thanks to Phil Cooke for driving the Hurricane mass build project, organising the event and keeping us all coordinated. Even the weather played ball eventually. Also thanks to Matt Jones for the original idea and prototyping.

From what I saw, every Hurricane that was maidened flew cleanly, pretty much out of the hand on launch.

In addition to the flying it was a great social event, sharing ideas and thoughts on construction and finishing of the models. All in all it was a great advert for PSS.

Here are a couple of pictures - off my phone so not the best. I'm sure people will pipe in with better images!

Phil that's a cracking Hurricane, really well done.

Here's mine:

Hawker Hurricane IIc.

Finished to simulate the last Hurricane ever built, it never saw service but was retained by Hawker at the end of the war. In 1950 it obtained the civilian registration G- AMAU and was used in the Kings Cup air race for a number of years, often flown by Group Captain Peter Townsend. In this guise it was presented in Hawker colours - deep blue with gold lettering. Following refurbishment in 1972 the aircraft was presented to the RAF BBMF and registered as PZ865.

The model is glassed all over with 25gsm cloth and airbrushed in Vallejo air paints. Decals are by Callie graphics. 3D printed pats include: 6 port exhaust stubs (Thingiverse), tailwheel ( file from Andy Meade), pilot from Real Model Pilots -self painted. Lights fitted to leading edges and to wing tips. Not sure of final weight yet!

Ive not got as far as adding panel lines detail yet, hopefully soon.

Here are a couple of photographs:

Hi All, just about there! Painting and decaling all done, wing servos in and I'm calling her pretty much done - just needs balancing and control throws sorting. Paint is taking a while to harden and I'm loathed to over handle the model at the moment.

So here are a couple of final pictures to show the finished model.

Maybe done for the weekend. In extremis I'll come down Sunday and use Saturday to finish, but trying for Saturday.

Hi All, Crikey this is tight! Sorry for radio silence Ive been head down on the Hurricane so thought I had better just get on with it! Must just be me - things seem to take me three times longer than planned! Anyway here's where I am... photos to share. I'll keep on going!

Hope you like blue!

Lovely job Andy, I like all the weathering. What weight did she end up at?

Hi Dirk, I put in a sloping cockpit base, then sat my pilot on a small plinth. I'll post a picture soon.

Hi Chris, not quite at the paint stage yet. I'm head down working towards it though, assembly is in process!

Time for a little update. I've pushed on a little more, finished glassing and got some primer on the tail feathers.

Need some more prep on the fuselage and wing prior to priming them - hopefully tomorrow, weather permitting.

I'm keeping on keeping on....!!

Glassed fuselage and components


Moulded light reflectors


Primer at last!

Hi Alan, it's green frog tape, as you say, it's stopping resin from entering cockpit base and sidewalls.
21/08/2018 23:22:52

I've been moving the Hurricane along a little more, being away for a few days has slowed up proceedings but I did get to visit the BBMF at Coningsby whilst away so that was a bonus!

Following all the discussion around nose weight additions, I have done a similar modification to the one done by Phil and added a hardwood core and a nut and bolt to the front fuselage.


Once complete I had this effect, its a 6mm diameter bolt cut down to around 50mm total length.img_20180818_115939294.jpg

Also got down to the first glassing of the accessory parts, mainly the tail feathers and the underslung pieces. The rib effect on the fin and tailplane remains prominent under the glass.


Pushed onto glassing the fuselage but not quite finished yet. The fuselage needed more work pre-glassing than I thought it needed (especially around the wing root fillets where I had gone overboard with filler).

I can tell time is tight - my workshop is even more cluttered than usual!img_20180821_194425437.jpg
