Typhoon Tail Titillation

Tiffie's tail continues.  Both elevators now sanded to final finish, and the rudder needed some attention too.  I re-made the TE top part of it, and also created a new trim-tab that will be secured after priming.

All on and connected, feels good :

I removed the tail-wheel assembly early on, so I neatened up this area with balsa planking and filler :

Sanded smooth this afternoon.  This will be glassed lightly before priming :

So with the hard remedial work done on the tail end, time to look at the nose.  I have a long length of M12 studding running through the firewall that is secured with large washers and locknuts.

This then protrudes through the cowl space and out through the spinner's location, giving me somewhere to attach the spinner, and hold some lead right in the front of the aircraft :

This will then get shortened down to a sensible length for normal operation.

Typhoon elevators, part 1

So, the Tiffie first.  The original elevators were quite heavy, and have been re-hinged many times, making a mess of the tailplane too.  A quick 10 minutes later with some 3/32nd balsa, and I've got the core of them laid out and drying.  Thicker blocks are there for Robart heavy duty pin hinges.

Then added the top skins with wood glue.  Their is a false LE on these of 1/8th inch balsa, which will have half inch balsa glued on the front of it for shape and strength.

Everything shaped here, along with a block balsa tip, LE's shaped, hinges added.  Much smarter, less wavy, and much lighter.  Next!

Workshop change-around; C17 / Typhoon / Rafale progress

It's been a while since I've posted, but things have been hectic.  I've moved a lot of models around the house in preparation for the new extension being built (work started today!), so now I've moved my benches around, creating a just "work" area and a storage area for the server and models where I used to have a workbench.

"new" workbench from through the room which is now model storage

"old" workbench, unmoved but cleaned up
So all that means is that I now have a lot more clear room to build in, and all my tools can be right next to each other.  Here is the C17 tail, undergoing a trial fit now as I am adding a location tab at the front.

Here's the location tab - two layers of 3mm liteply wood-glued together, and gorilla glued into the tailplane assembly.  This will then fit inside a liteply pocket in the fin.

So whilst all that was drying...the Typhoon fuselage also had some love - I removed all the servos and wiring, and started on sanding down the paintwork.  A couple more hours on the sandpaper and I will risk a light primer coat to see how smooth she is.  I'll be building new elevators and rudder, as well as a new cockpit installation in this one.

Then lastly, the Rafale is nearing the end of it's build.  Here ready for bottom colour..

Bottom colour on!

Cockpit masked ready for primer...

Primer done!

Lot's more to do on all the airframes, but things are so much easier now with the reconfigured work area.

1/6th Scale PSS A10 Thunderbolt II - all done (again!)

I rushed to get this one done for the Orme event, but as it turned out, there was not enough wind for me to risk chucking her off.  Anyway, I had forgotten to put photos up, so here they are.

Re-painted, weathered, panels lines, then lacquered

on the balancing rig

PSSA at the Great Orme - October 2017

A mixed event really - lots of new planes to see, and great to see the guys again with a great meal out.  Rain interrupted play on both days, but Sunday had the best wind if a little off the main slope. 

It looks like we'll manage at least a couple more gatherings before the year is out though.

Oh, and yes the F15 flies - just needs the C of G tweaking a bit, and she'll be good to go :)

PSS HET Rafale - into primer

Not that much of interest really - the Rafale has been filled where necessary, sanded down all over, and primed ready for some colours :



Before spraying - filler lines and some cockpit detail in pink foam

PSS HET Rafale - build continues

The little Rafale is coming along well.  The new "removable" tail had an incident when I was tacking the carbon tubes into the fuselage - cyano managed to wick around the ends and into the tube and dowel.  It stuck solid within seconds, so that was that!  No amount of tugging would free it, it was in solid.  Only one thing to do - go with it!  I firmed up the rest of the joint all the way around, then took everything for glassing.

Fin side one glassed :

Wings glass on bottom :

Then top :

Then line up and epoxied into the funselage with 1 hour epoxy, after a good blocking back :

I'm looking forward to being at the controls for the little beauties maiden.

PSS builds - F104, Rafale, A10

The F104 progressed well through paint and into lacquer this past weekend, so that's all done and ready to fly again, short of a quick check on the C of G.  I'm hoping the small amount of lead in the front can be removed to allow her to be weight neutral after the repairs!

The little Raphael has had some work done on it, as I am waiting a large run of free time to mask then spray the remainder of the A10 parts.  The new tailplane has been top-coated, and the fins and rear flying surfaces have also had a smattering of white enamel, ready for the camo to be re-applied.

Anyway, the Raphael then.  First off, remove the jet pipes.  These just get in the way and add weight that I don't need :

One out..

I can see through now

Both out!
I used the pipes to create balsa blanking plates for the intakes, then glued them in thickened epoxy.  No pictures yet!

Whilst the dremel was still out with a cutting disc, I sliced off the fin spigot from the top of the fus, as that's not needed now either :

I made up a small radio tray, to which I mounted the servos and a switch, then stuck that in again with thickened epoxy :

Here is the new fin, made from balsa - 16g!  The old glassfibre one weighed 55g, so a decent weight saving from the rear of the aircraft.  The fin will be plug-in-able on carbon rods, so some of that weight will come back, but not much.

A small change to the A10 - both engine pods now lined with 1.5mm black ABS for smoother airflow:

So, some spraying in the garage this week as I want the A10 ready for 2 week's time!
