I've always loved this model.

I've never had a full-size, but once built the Boddo "Astro 40" for an OS .40 FS.

It flew beautifully with the "vintage" dihedral and I rarely used ailerons.

Hence this R/E version.

I blew the 3-view up as large as possible onto A4 and it came out at 16" span, hence the 32" model.

Aww cute!

I assume you are not replicating the original's complicated structure?

'Fraid so, but I've kept the tailplane standard. It's classic.

Instead of sheeting the L/E I used riblets, 'cos I like 'em.

... and a bonus pin-up of yours truly.

Eh?

I think the colour scheme is going to depend on what I've got in the box.

The one I remember from way back was metallic pale blue (Jaguar) with pink nylon-covered wings. It looked beautiful.

It was flown on reeds by Rowly Craggs and belonged to George Coulbeck and was the first model I ever saw flying knife-edge.

I'll bet slopdog remembers it too.

Ooh! I've found some blue Solarfilm for the fuselage and also some translucent blue for the flying surfaces so you can see the structure through it.

Should be nice.

Rx and ESC ordered from Giant Shark, so we're not far off.

Gordon W · « **Reply #24 on:** January 28, 2013, 17:14:05 PM »

That's really very nice

A couple of questions:

1. I thought we were only allowed 5 photos per post. How do you manage to post more than that?

2. What will you power it with? I have a redundant Graupner Compact 160 7.2 1380 rpm/volt indoor motor.

This produces a fair amount of thrust on a 7.5 x 4 Graupner slowfly prop and a 3s lipo. I'd been wondering whether to sell it as indoor has died a death round here, but seeing your li'l Hog project has given me a few better ideas for things to do with it

Gordon

half throttle · « **Reply #25 on:** January 28, 2013, 17:24:51 PM »

Hi Gordon, thank you.

I'll look at the motor next time I go up to my balsa destroying room, I can't remember off hand.

As for the number of photos - I just keep adding them in "Attachments and other options" and have never had any problems.

I really do like these smaller models and can't stop building them.

West Wings Cub, Fokker E111, Fokker Dr1 and now the baby Hog.

This is the injin Gordon, from Giant Shark.

It will happily swing an 8" prop.

Gordon W · « **Reply #27 on:** January 28, 2013, 23:26:59 PM »

Thanks Paul, that's quite a meaty motor

No Cells: 2-3s Lipo
KV: 1534
Max Watt: 195W
Current Capacity: 16.5A<60s

195W is around OS .10 territory and your Hog will definitely perform!

Nice to see one of the scale experts weighing in! (Well it is a scale model, after all...)

half throttle · « **Reply #29 on:** January 31, 2013, 11:02:39 AM »

Finally started covering and - yes - I did remember the U/C blocks.

But I forgot the wing mounting dowel.

At least I haven't got the top of the wing covered yet, so a bit of careful butchery is on the cards.

I was going to try some VHS tape for the hinges, but found some thin Mylar ones.

Has anybody tried VHS tape? I slit a piece of 1/8" sq and slid a piece in with a dab of thin cyano and it won't budge in a million years.

Installing gear

A 2s 800mAh battery is a nice, snug fit and these little Corona 35MHz synth receivers are amazing.

Riblets, riblets. riblets. Yes, it has a nice ring to it, doesn't it?

Well, it's all over bar the shouting. (and the motor keeps coming loose!)

Except the damn Rx was faulty and it's now working on one that's been in a lake in my Gemini!

Last few photos.

What next? Hmmmmm...

Full-size Vic Smeed Chatterbox methinks - only 30" span, so perfect.

Thanks Mike, I'm really enjoying my building at the moment. It's certainly the weather for it!

Models this sort of size (30" - 36") certainly come together a lot quicker and, even including the power train, don't cost a lot.

Must get the Dr1 100% completed before I'm tempted to look through my 3-views.

I downloaded it as a vector .pdf and used this http://www.lucubration.com/pdf-tile-printer to tile it.

You just beat me to it Mike!

The more I studied the plan, the more tricky bits I found.

I have since discovered, however, that if you mess something up, you can always make another one.

And there's no rush, I hope

I'd better get a ship-load of 1/16"sq stringers on order.
