Heinkel 1076

[chris collis]

Back in 1996 there was a free plan in Rcm&e for a Heinkel 1076 at 32in span. I built one and am curious if there are any other ones in existence or if anyone has ever contemplated building one.It’s been a brilliant flyer over the years,both as electric and Pss. I also enlarged the plan and built one at 54in span,with the swept forward wing ,another brilliant flyer that was responsive and stable.With all the newer building techniques and materials and brushless motors, it may be an interesting project for someone,especially the larger version. The plans are on outerzone I believe.Anyone tempted?

[chris collis]

I forgot to ask if anyone could build these out of fibreboard ,depron or other lightweight materials?Would they be suitable?The 32in one was designed for a speed 400 but I changed it to a small brushless motor.The flying photos are of the 54in span 1076.

[Eric Robson]

There should be no problem using foamboard and depron, I have built many various aeroplanes with it my biggest is a 104"span Lancaster,on average the others are about 60" span.

[chris collis]

Hi Eric,Would the 32incher be a bit too small for depron or fibreboard just for durability?Up until now I’ve never tried to use the above materials,always been a bit of a balsa and foam basher. 

[Eric Robson]

Hi Chris,  small is good with depron, not as durable as balsa but generally easier to repair and much cheaper. I use balsa or ply for wing spars and reinforcement but very little. A 60" span airframe  will cost about £20 _£30 

[chris collis]

So the airframe itself could cost as little as a tenner!Sounds exceedingly good value for money.Just as a byline,does anybody still use Japanese tissue these days?

[Graham Davies 3]

Chris, you could definitely build either scales from depron. The smaller one would build very quickly and easily in B&Q (diall) 3mm laminate floor insulation, and at that size will need very little in the way of spars etc, so the weight will be very low. I reckon £10 is too much! 

 

Great subject, and a canopy ideal for a coke bottle!

BTW, you'll not need much from your original plan! Just the overall outlines. Shout if you need help or a starting suggestion...

[chris collis]

Hi Graham, I’m just at the pondering stage to build another 54in one as I think I still have the blown up plan knocking around somewhere.Many thanks for the offer of help if I do give it a whirl.My original airframe was stolen a few years ago. I do miss it.

[Eric Robson]

Graham is giving misleading information, you have to buy a pack of B&Q depron which will set you back more than a tenner. Good thing is you now have incentive to build more models to use it up. Be very careful it can become addictive as you scouer the Internet looking for rare subjects to model.. don't forget to get a good stock of Stanley blades and Uhu por. 

65"span 109f made from foamboard and depron, most expensive parts were the spinner and retracts. Some balsa and ply used for spars and motor mount etc 3mm depron sheeted .

[chris collis]

Looks absolutely brilliant 109! I didn’t realise that you couldn’t buy just 1 sheet, so if I do decide to build one and can’t get away with it I don’t want a stack of board i won’t use!

[Graham Davies 3]

Trust me Chris, you'll use it! As Eric said, it's highly addictive as you can easily model from very basic information. If I could only get a tiny bit more info on Dick Dastardly's biplane...

You can revert to it's original purpose and use it for insulation. 

You can buy individual sheets of  Foamboard from Hobbycraft I generally buy 4 at a time at a discounted price.

I’m now considering maybe having a go at trying this foam board construction later next year with the information that you’ve given me,many thanks.I’ve been looking at some of the designs from Luft46 of German prototypes and they have peeked my interest for next year.At present I’ve got a 96in Sunderland,balsa construction,on the board followed by a Fockwolf190 and a 4mtr Dg808.

My depron and foamboard Sunderland 72"span 

[chris collis]

Absolutely brilliant!Mine will have hopefully,two wings built,one for power and one for PSs .One question I have is, what colour would you do the panel lines on the fuselage?cheers

[Eric Robson]

The panel lines and port holes are black felt tip pen, the  wing roundels are also done with a felt tip. 

 

 

 

[chris collis]

Many thanks Eric,will try it out when I get to the finishing stage.could be a while yet.

Hi all, I can see how the formers etc are used by the exellent picture, but how is the upper turtle deck covered ? Thank you

[chris collis]

The decks were carved out of a blue foam block,hollowed out to keep the weight down and then covered with solafilm with a low to medium heat iron 

[Fly Boy 3]

Thanks Chris, looks like I need a lot to learn about foam etc.

[chris collis]

You could also use 2 sheets of 1/64 ply laminated over the deck formers.

As the Sunderland is the only one showing the formers I assume that is what you are referring to, in which case it is 3mm depron  sheeted.  Depron has a grain,  I establish the direction before sheeting then work it over tube to form the curve.

Thanks Eric, Been building for over thirty years in trad. materials, but your Sunderland blew me away.  Cheers
