Fitting the wing to the fuselage for the first time in any build is always a major milestone! Even if you work for Boeing or Airbus!

Looks great btw... thumbs up

Lovely neat building Chris, and some nice robust engineering with your little battery cover!

Just rattle cans for the primer Chris, top coats will all be airbrush. I do feel a bit better now its not all pink.

The weather was good so with the spray jig complete we got some primer on the wing in the garden!

Two coats in fact, with a very fine sand between them. Dried really fast in the warm weather and the surface looked really good with the pink sauce now hidden beneath!

Not much to report really over the last couple of weeks - around work and family my modelling time has been utilised in other ways - either reporting on our last event or working out how (or if) to run our next one in October! Fingers crossed we are not all on a full lockdown again by then!!!

I'm still final sanding the fus in prep for glass...crying 2

The wing received another coat of 'sauce' on the underside as I had noticed a little sag line along a join in the skins - this has now been remedied and the wing is ready for final primer then paint. To aid that process I've built a little painting jig so the wing can be held secure via the wing bolts in either orientation. It's not as cool a design as Dirk's but it's functional. Should make the painting a little easier.

Some foam enables a soft grip at the back around the nylon bolts.

And at the front the wing just drops on around the wing dowels. Just high enough off the bench for the airbrushing...

Good going Chris, you are fast catching my position - I'm afraid I'm still sanding my fus finally before glass!

Also, with learning from the smaller parts like tailplane panels and ailerons who have had their final primer coat, I'm adding another coat of sauce to the wing panels as there are areas where perhaps I have oversanded as you've suggested...no pinholing is evident which is a step change from previous glassing, but the primer did show just the slightest eveidence of weave patterns showing through. So in trying to minimise the primer use on the bigger parts I think another final coat of sauce it is!

... and we hope to see you on the Orme too Chris!

May 2021 is the current 'target' date for our MB Sabre event... Covid allowing of course, we will continue to monitor and adjust as needed to ensure we get the very best from this event.

Yep - the AR-555 flew really nicely once the CoG was tweaked - really impressive! - some photos of it in the album Ive finished editing here

September Orme

07/09/2020 16:33:56

Monday night and I'm still shattered after a fantastic weekend of non-stop PSS flying on the Great Orme - what a superb couple of days we've just enjoyed! - many thanks to everyone who attended. We flew from 8:30 am on the Saturday in good strength WSW winds. Everything flew - superb conditions with winds upto 35mph. On Sunday it was a little lighter and had moved round to the NW by midday, from there we flew on until 6pm in winds up to 18mph. As things slowly start to return to a new normal we even managed a meal on the Saturday night in town. Great social as always!

There was a huge number of new models on show and being tested for the first time, odd for this time of year - another sign of the strange late start season we find ourselves in maybe?

A full event review and photo album to follow as soon as I can edit.

yeah great job Rob - lovely to see these finished Sabres being tested out and flown despite us having to put the Mass Build Event back to next season... look after her!!

She looked to go really well straight from the launch! thumbs up

glassing, sanding, saucing, sanding, saucing, sanding... it seems to go on forever!

I gave my tailplanes and ailerons a second coat of top primer today as there was 'just' the slightest evidence of weave after what should have been their final finish sand... difficult to know how much 'coverage' the top coat gives with the airbrush - probably very little as the paint goes on so very thin... so Im happy with the second primer coat first I think!

From baby talc pink to battle ship grey! Good to get some of the parts in final primer beer

Yep thats the idea, depending on your aileron stock and its minimum thickness at the extreme T/E - the idea is you can sand right down to the ply top and bottom if required and still have a crisp, robust T/E corner on the tip. It needs to match your aileron T/E dimension though, so if thats a little bigger than the thickness of the ply alone then there may be a slither of balsa remaining on top or bottom (dependant on the section)

26/08/2020 20:56:08

Nice job, it is rewarding when the 3D curves all start to take their final shape. Did you sand right down to the ply at the T/E at the back?

Thread: Chris Foss Phase 6
26/08/2020 20:53:42

Perfectly doable I'm sure, but there is not a lot of cross section on the fuselage up front, it's a lot more pointed than say the Middle Phase or Phase 5 (which has recently been converted and kitted for electric) so you'd have to cut a fair bit of nose back before you got to the sort of shape to suit the diameter of the motor and mount. That would really ruin the lines.

Theres also not a huge amount of room under the wing seat for a Lipo either, particularly if its built as per the plan with an elevator pushrod and rudder cables running within the fus.

Of course you could mount it all externally on some sort of power pod and tray, but that really would detract from the designers intent on sleek lines.

Final job before the wing can be primed was to cut out and fit the little wing fences. No two diagrams I have for the Sabre show these fences quite the same shape, they seem to vary in length and some have the L/E and T/E angles perpendicular to the wing surface some have them vertical. Anyway I've sized and shaped them to what I think is correct...the important thing is they are true to the airflow and vertical when viewed from the front!

I cut the fences from 4 pieces of 1/64" ply, cross ply laminated to make them nice and stiff at 1/32" final thickess.

The wing was carefully marked up, the slots were cut with a brand knew scalpel and cleaned up with a file such that the fences were a nice push fit.

They will be removed and primed separately to aid priming of the wing but then glued in place before the final top coat is added.

Hey nice one Steve - great progress - getting this fus shaped has taken me way too long too!

Looking forward to getting to the stage you are now at, ready for the final top coat and all the detailing - enjoy this final few stages!

Fantastic to have you on board and taking an active part Skip - it's great to read that the website and magazine articles have influenced you (and no doubt others) into having a go and building traditonally from plans, this has always been one of our main objectives in the mass builds!

I look forward to seeing your Sabre develop. Plenty of time now we have put the event back to May 2021.

Stay safe and enjoy your building!!
