Just to echo Nick's post - happy new year to all and thanks again to Luke for his diligence in maintaining this thread, especially the gallery and resource links in the first few posts. I'm sure that the info accessible there has helped many hesitant builders to have a go at one of Ivan's designs.

The fact that, in over 3000 posts, despite many heavily 'customised' builds (and some just plain heavy!) , nobody has reported any adverse flying characteristics should provide some re-assurance too!

Actually, there is one Ivan design that can be a bit of a handful at times, but there's no plan available for this one.

So, Happy New Year to Ivan too.

Trevor

New project!

I have not built anything lately, so this is what I'm going to spend my spare time on for the foreseeable future..

Happy New Year!

Good luck with it Arvid! As you mention, there are several Spruce Goose models that have come before, but I don't believe any have kept to the Ivan design philosophy. It would be a real treat to see such a thing fly, and there's no one better than you to pull it off!

Luke, that great marking scheme that you came up with a few years ago is really getting around. Including the Solent that I did I think that it's three, now.

Hi Luke I'm going to pm you and some old friends ..at the moment I'm looking around and trying to see whats been going on . Looks like there's been some losses and a lot of gains especially in the plans and design fields.

You are correct Luke all the trad construction H4 s ..ive seen built have tended to get into very complex construction, fantastic results but OTT...... Im actually wondering if the Huge Tony Nijhuis's big Spruce Goose is actually the closest to Ivans methodology , it certainly uses an Ivan power train geared brushed Permax motors.

Just how would the Big goose compare in scale terms to say the Solent or Mars?

The seaplane base in Bergen used to be just south of today's airport. They still have a cafe called the Sandringham.. A few Sandringham flying boats were used on domestic routes in Norway just after the war. They were operated by DNL, which later formed part of SAS some 70 years ago.

My H-4 is scale 1:25, and Ivan's Mars is 1:20

High Arvid I think I was looking at the place near the road tunnel just up from the old harbor. I was only there for a week end and I was visiting/working for a local company. They took us out round the town ..I kept being mistaken for a local ..till I opened my mouth lol.

Had a look just looks good you and Bart have done some fine work Im wishing to see a certain persons Saro Princess completed and maidend

I will try to keep an eye on your goose its looking true to Ivan so far .... Ive never seen how the big TN one was actually constructed.

Does Ivan have a version of the DHC-1 Chipmunk with a span less than 75 inches?

I don't think so. However the 75in one comes in well under 5lb so is by no means a heavyweight. If you have storage or transport concerns then the low wing loading means that modifying it for a two piece wing or even plug on wings is hardly a major engineering job.

I'm sure you have your reasons for looking for something smaller, but you won't find a sweeter handling version than this one!

I concur with Trevor.

Ivans Chippy was my first Ivans machine and I have used and abused it quite severely.
I used to fly it from football pitch in all weathers, including snow and ice. When the field was covered in puddles I used to enjoy taking off and landing in the small areas between them.
It could take off in under 5 yards from a standing start and land at a crawl.
She is so forgiving I used to use it to do buddy box training. She just feels right.

Do not worry about excess weight, mine weighed around 62oz but I did also fly it with a "payload" of 2.2 and 4.4 lbs. Obviously the take off was longer and the landing slightly faster but she showed the same benign charecteristics.

As you can probably guess, I love my Chipmunk.

I agree entirely....
I'm seriously considering making an IP style Dornier SeaStar (as its an easy amphibian to do)

1/12 scale brings it out at 58.5 inch span which should make a nice little portable model, though I may go bigger (need to work out storage/transport things)

In the meantime, I've been making space in my hanger....
