I spent an hour or so tonight marking up my tracing ready to cut out the covering for scallops. Due to the ribs not being exactly spaced, the centres and diameters are a little different to get them to line up with the ribs.

They won’t be exact, but I don’t think they will be far off.

Today, I got the other aileron to the same state, then made up the linkages for the ailerons, then had a proper clear up on the bench.
I got the first piece of covering done too.

Hi Peter,

Yes, definitely gluing them in after covering. I'm trying to get everything finished, so that I'm not having to make things after the covering is done.

I got both of the ailerons cut from the wing today along with the port side sanded to final shape and hinge slots cut:

9e662c19-0bee-4c4a-8954-41ac8c884cb6.jpeg

I measured the leading edge of the aileron, for the part that is parallel, it is 20 mm ish. So I set up my calipers to 10mm and scored a centre line all along from the bottom edge, then did the same with the wing. Cut the hinge slots, then sanded the bevel on the aileron:

There is hardly any bevel on the top edge at the wing tip end.

Hi Chris,

Thanks for your kind comments. I have thought about a tool for those, but I still haven't worked out the specifics yet. While I keep getting passable results with the needle files, I think I will carry on thinking about it...smiley

The last couple of days has been spent, amongst other jobs, tidying up all of the loose ends, hinging, control snakes and fiddly little jobs that I dislike at the end of a build. I even made up a template for the windshield. Now just the ailerons to cut out of the wing and hinge up and its onto covering.

I made up the steerable tailwheel to the same design as I did on my Ballerina. It has worked well and there is no reason this shouldn't do the same. (the rudder horn mounts onto the 2 holes and locks everything together)

Hi Gary,

Thank you for your kind comments. For the exit holes, I just very carefully opened them up with a permagrit needle file, I also find the riffler files very useful for delicate work:

Hi Peter,

That sounds interesting, I look forward to seeing what you are up to, if it goes ahead.

Todays little jobs consisted of the final bits at the back of the fuselage:

And I thought I had already done the Horizontal Stabiliser - obviously not, so here is the blank made up and ready to sand to shape:

Hi Peter,

Yes, it would be nice to be able to remove the legs. I’m just following the instructions...🤔

Today, along with getting yesterday’s stuff all glued in and sanded to finish, I have made the switch plate and got it installed. I left it a tiny bit proud of the stringers, then sanded it back flush. Plate from 1/8” light ply, with balsa spacer block.

Morning Gents,

Ooh, a reliant. Somebody local had a robin with some mega engine grafted into it, can’t remember what it was, but he had to put ‘wheelie bars’ on the back, because it would. The standard ones went pretty well.

Photos from yesterday. Probably the hardest part of the build so far, was also the smallest, making up the wedges for around the undercarriage legs.

As I had the vice set up on the mill, I also put the flats on the legs, before fitting them.

Hi Gents,

Peter, are you making any progress with inspiration?

Nigel, Thanks for your kind comments. My covering is going to have to be ‘on point’ with this one.

I haven’t done much today worth showing on Peggy Sue. Just painted the tank bay and inside of the cowl with the first coat of Solarlac. Whilst this was drying, I turned my attention to making the nose leg steering mechanism for the Cougar.

I have been thinking about this for a while and came across this video on YouTube **LINK** With nothing better to do, I had a go:

9011bcee-d2de-4ecd-bc59-1eb8a874b8ea.jpeg

Still a bit of work to do at this, but it has proved the concept and I’m sure it’s going to work great. Even without the slider plate that the pushrod needs, there is very little slop. I will program my radio to turn off the noseleg servo when the gear is retracted, even though the design allows for it to still operate.

Thanks go to Martin Newell for his design.


Cheers

Mark

As the wing is now nearly complete, I decided today to get the holes drilled in the fuselage for the wing bolts. I spent a good amount of time setting up and getting the wing square then made up a small piece of 5mm tube to use as a drill guide to drill a 4.5mm pilot hole for each T nut:

50b98708-0850-4cb9-a56f-d8dc8324da53.jpeg

With all of the holes drilled out to 4.5 mm, I then gently opened them up in small steps to 6.4 mm. Then, using a steel bolt and a couple of washers, got the T nuts installed:

The wing fits well, and the 4 fixings locate it nicely:

a3aff1f7-e41a-4732-96f5-a291bf984ae0.jpeg

I then filled and sanded the wing, it now just needs going over with a fine sandpaper and it is finished, apart from cutting the ailerons free and hinging them:

Next, back onto the fuselage that needs a few more jobs doing, then its covering time.

Hi Gents,

John, thank you for your kind comments. Hope you are well and keeping safe in the current situation.

Keep looking Peter, we all need some of your modelling inspiration in these difficult times. I look forward to seeing your articles.

Nothing much done today, I had to go to work in London. Didn't want to, but key worker status meant needs must. At least the roads were quiet and I got to work in a closed Park outside in the glorious sunshine. Nobody much about, it was very strange.

Cheers

Hi David,

Oracover do a transparent purple. I have some for my Peggy Sue build, I got it from RC World in Wales, they were still open last week.

I have no connection, just a satisfied customer.

Edit. They also do a Flourescent Neon Pink...... you won’t miss that. Sacrilege...

This is the total of todays work:

While the epoxy was going off on the servo rails, I got out the plan for the Cougar and the retracts I bought for it ages ago and set to work planning how I'm going to get them to fit. Not an easy task, but I think I am now on the right track to formulating the plan.

Hi Peter,

Thanks. Look forward to seeing those. I have finished your 4 stroke book, good read.

Yesterday and today, I have made a start on the wing servo plates and their associated mounting points:

I found a length of 1/4" square Cyparis in my stock, so have used this for all of the mounting points.

Hi Peter,

Many thanks for your kind comments. It must be annoying to get so far, only to shelve it.

Yesterday, I got the leading edge cap strips glued on after pre-bending them:

3c95d26b-7741-4932-91ef-d3dc952e6c35.jpeg

Then this morning I made a start on sanding. There is still a lot more sanding to do:

59dd2883-b29b-4a98-8995-9839e76c2e77.jpeg

Whilst the glue was drying yesterday, I didn't really have a lot to do, so I made a start on the throttle extensions for the 2 saito engines for the Cougar.

4180c346-bb71-4419-99b9-c6c089f92c2b.jpeg

Due to the placement of the tanks and the throttle servos, the throttle arm needs to be moved out by approx 1". I initally made up an extension out of brass bar. Before cross drilling and tapping for the grub screw, I weighed it, 17g. That is over an ounce for the pair.

I decided to change tack and make them out of Aluminium, although I am a little sceptical about the 3mm threads that will take the grubscrew. I'll worry about that later.

11ac8cce-43ed-447e-955b-05ebc2559e36.jpeg

a45dd3b0-790a-4a04-8307-9db4a3c46441.jpeg

The brass one is complete, except the cross drilling, the ali ones are rough and still need the spigot making for the throttle arm. In this state, the ali ones on the scales together are 17g.

More work to do on those yet.

Today, I have got started on the tip ribs:

6cf67336-d9f2-4a6b-b780-e5bb70aa8fce.jpeg

I made up a couple of 'spacer' blocks, both the same length, to assist with getting the ribs in the correct position.

8aa7e3d5-09b4-46ee-b506-c995b20fce51.jpeg

Once these are done, I need to get on and make up the servo mounts and their associated mounting points in the wing.

Cheers

Mark
