The Pete is covered with airspan and a sprayed on coat of thinned sig litecoat. Blue color is polyS acrylic. Very light and the cream colored airspan is perfect for WWI jobs.

Pat, I've just piled it on the scales and can report the following:

Fuz, including cowl and U/C with wheels - 6oz
All wings - 4 5/8 oz

How does that sound?

Pat, your 'Pete' is beautiful, however I've got the litespan in now so that is what I plan to use. I will have to give that stuff a go soon though.

Been away on holiday and had some work commitments that have kept me from my Pup for a while, bu I'm back on it now although the jobs now seem to take longer and you have less to show for them, anyway here are a few more progress shots.

The Cabanes are from laser cut 1/8th ply with 1/8th sq balsa stuck to both sides. You can also see I've added some locating pegs in the cowling, I will probably add some magnets in here too.

The side cheeks have been added and the cockpit floor.

I decided to shape the balsa top decking by wetting a little with windex and rolling around some beer cans, probably not absolutely necessary but it seems to have helped in getting everything lined up and in place properly.

More soon....

Thanks Dave,

Deck is now fixed in place, just needs a little filling and sanding here and there. I gave the cockpit innerds a quick slap of brown paint before access was restricted, just to pretty it up a little.

You can also see here that I've been experimenting with a Le Rhone picture to go where the engine should be, needs a little more work and I need to consider the cooling issues too, but the idea seems to have merit

Also picked up a 1/9th pilot that was a close to the 1/8 needed that I could find and I think he'll do fine

I've been following this thread and since it's been sort of quiet for a while i just wanted to bump it.

The Pup is such a great looking plane and i think you are doing a fantastic job with it!

Best regards,

Thanks 'The End',

Progress has not been as rapid of late due to work commitments of a new job!

But at least it has helped to pay for all the bits needed to equip the pup!

I am still making progress, the U/C has been put together. The wire struts are bound to the ply frame with dental floss before soaking with CA and then going over the whole whole area where ply meets wire with epoxy resin. Seems to have made a strong unit, time will tell !

Other recent jobs have included some sanding and filling of the fuse/cowling and fitting the servo plates to the lower wings.

I should be starting the coverring any day now.

Where did you get your pilot from? I'm still looing for one for my DH2. Great looking Pup so far, by the way!

I got the pilot from Slough Radio Control Models, they seem quite well distributed in the UK, I've seen them in a number of shops and I think you might be able to get them online from SMC but again this is UK and I don't know if they ship overseas? They are made from latex and are quite light.

More progress on the Pup,

The upper wing is now joined and most of the sanding and shaping is done, just have to sand a bit more laser burning away, beginning to wish I'd done this as I went along, too late now and makes for a trick job with a few ribs needing a little repair here and there

I've started the coverring too. I'm using Litespan throughout with Balsaloc and I've started with the tailplane. You can get a nice tight finish if you get it taught before you shrink.

I've added the factory details to the Vertical Stab by working from photos, outlining in pencil and then going over with a fine waterproof marker. The litespan needs a little re-tensioning where the light pen pressure has caused a little sagging, but I don't think it looks too bad

The rudder has been covered in white and the red/blue will be painted on later.

Oh yer,

Anyone got any good Le Rhone photos for me to make a better job of the engine image?

Update time!

I decided to go with Pull-Pull controls on the Pup after consulting with Kurt, although the plans show pushrods. I just like the lightweight and appearance of the wires .

I had to make a few mods to get it to work, firstly I added balsa supports at the exit points within the fuz and then added some thin plastic tube guides. I have also added some new elevator horn supports a bit further outboard again to be nearer to the scale set-up.

I've added some scale cooling holes to the underside of the cowl. These still need some more sanding/finishing off, but you get the idea.
