Hi Martyn the plate is just butt jointed. I may add some 1/8 square triangle stock underneath, to just spread the load a little. Though it is plenty strong.

I am surprised more modellers are not using RDS, though it does rely on accurate building, maybe that puts people off?

A friend is trying some very hard plastic in his 3D printer to try and make the "top-hats"

Cheers

Danny

Thanks Danny. If I had seen this first, I would have gone down this path. It is so elegant. You can actually pick up small samples of formica from Wickes DIY in the kitchen section. They would be perfect for stuff like this.

I have just acquired a 3D printer. Making Top Hats with a splined inner seems like a good way to faff around. Apart from that, I cant see how a hobbyist could cut splines in a tube of that diameter unless you have a micro milling machine

Yes a quick google brought me to that conclusion as well. The top hats don't take long on the lathe, some alloy, grub screw, and 2.5mm mushroom headed screws. And it gives me an excuse to play with the lathe for an hour or two

Well just to prove the first wing wasn't a fluke I fitted the other aileron and RDS box.

this one is better then the first and operates really freely.

I will say don't get these Corona servos, not sure if it is the metal gears but the play around centre has ruined the carefully created RDS boxes. There is play in setup. When you look its not the RDS system its the flaming servo disk!! Anyway it will be fine on this model, but I shan't use them again. Should have stuck to Hitecs

Chris Bott spotted these the other day and might be worth a look.

Anybody know how to cut splines on the inside of alloy tube?

Cheers

Danny

Danny - would these from the same website be any use?

Hi David, no they have a bulge underneath as opposed to a dished out section.

Cheers

Yes but a couple of minutes with a larger drill could provide something useable for those with no lathe.

Hi David there is an easier way, though a bit heavier. Solder a penny washer to a collet

Watch this space, maybe some 3D ones will come along

There may be a short interlude while I put together a model for some under 5kg FO comps

No point Tony it is flying only, so nothing to be gained. why risk a multi month model when there is no static?

I will fly the Fury in this class, but the first few comps are soon and the Fury wont be ready. Monkeyed about with the bulkhead and got the motor fitted, so should dn't take much. The tailplane appears to be made of oak!! really tempted to bin it and make another.......

Cheers

don't forget the rivets sir.

That Tony is a difficult one.

I have a real problem with ARTF's. They are great don't get me wrong, but I cannot resist changing them. All the surfaces are hinged wrong, the canopy is wrong, the tailplane massively overweight etc etc.... But I mustn't.

They are what they are. Changing them just adds masses of time, and it still wont ever be right!

It is just me, I know, but I really must try and leave things like this alone.

If anybody is interested I can do a blog on another thread?

Cheers

Danny

Well now that the distractions of the indoor Nationals and the Chipmunk ARTF are out the way, probablt should get back on to the Fury. I like many are really struggling to keep going with this one.... But a little a day and it will be done.

So I removed the brass bits and give them a gentle bend. I then sanded sections from the rib cappings to accept the ply cappings. I then CA'd the brass to the spar (yes, I did add some block between spars)

Strong crochet thread was whipped around the brass and spars, this was then soaked in thin CA

The ply capping pieces were then added, making sure they were flush with the balsa rib cappings

Been lookng at the position of the rear flying wires. They attach to the lower wing, near the root. As I have split my wing into panels I have fitted brackets to the ply ribs of the centre section. This position should be plenty strong enough.

To achieve my aim I had to remove some of the centre section sheeting. This was cut at 45 degrees to make replacing the cut sections easier.

Maybe more later if the sofa doesn't swallow me after I have eaten

Oh I meant to say, those lovely counter sunk screws are M2 from Modelfixings, an excellent supplier.

Slight snag the M2 use an allen key that is so small I don't own one! A small jewellers screwdriver worked, but I have some tiny ones on order. I believe the allen key I need is 1.3mm

I have 100 of the M2 and a 100 M3 for the various bits of rigging etc.

Still in two minds whether to use the nice Mick Reeves fork fittings or just plain piano wire.......

Cheers

Danny

While I was idling wondering what to do next I filled in the root rib area on the lower wings. I guess that seals it, I am not doing a Nimrod but back to plan A, a Fury.

... "Seuls les fous ne changent pas d'avis", Danny...

A well known French idiom meaning > "Only fools don't change their mind"... cool

Back to plan A, you wrote... is it going to be the 'camo' one or a 'training Fury'???

Cheers

Chris
