Jon is right, as usual, but it doesn't tell the whole story.
Stalling the top wing first is best for stability, but makes it difficult to perform aerobatic maneouvres that require a stall, e.g. stall turns, flicks, spins. If your biplane needs to be aerobatic, have the top wing a degree or so negative to the bottom, but be careful on landings! Zero-zero decalage is a good compromise between the two.

In my case, my 25-year-old 1/5th scale Svenson Stampe has the top wing 1* positive, the 38 year old Aeromaster has the top wing 1* negative, and the more recent Jungmeister and Christen Eagle are both zero-zero.

All of them are excellent flyers in their own ways - the Stampe is a lovable, stable trundler, and the Aeromaster is a very wick and lively aerobat!

Work out how you want the aircraft to behave, and then set the decalage accordingly.

Steve.

Yup, true enough Steve. My stampe seems to stall its top wing first. I can feel it in loops and it also nods forward if you get too slow on landing.

Wing sweep also makes a difference as swept wings tend to pitch up at the stall. Something like a pitts has one straight and one swept if i recall so setting -1 on the top wing vs the bottom would make sense. A great deal would depend on the wing section too. 

I think on my next stampe i am going to build some sort of adjustment into the rigging to allow tweaking if i so desire it.

On behalf of the current full size owner of this Stampe G-AYGE would the builder/owner of the model I guess Tony please make contact with me. If you are interested there's a photo opportunity for you with your model and the full size and then a flight in the full size Stampe. How good is that! PM me for contact details. Or if anyone else can put me in contact with Tony, that would be great.

Resistance was futile and after 22 years since building my first Stampe (fitted with a Laser engine, 120 or 150 Can't remember) I have just purchased a new Slec Stampe kit. Will be fitting a Laser 180. Been great reading through this thread with so many useful tips so thanks everyone for your posts.

Can I ask for some advice please on which wheels are best suited and also which size/make of fuel tank to fit.

I think the last time I contributed to this thread was 24 9 15, and I have not finished it yet ,

BUT the Porter has been sold on and hence I have an engine , DLE, that will allow me to continue with the build .

I am not a fan of fixed incidences , and I do like them to be adjustable to some extent , see the post on the 29 /9/15 to see the mechanism on the top wing support to allow this , Preference on my other bipes has always zero to a tad of negative for the top and zero to plus 3 on the bottom , sedate is not my style , but the flying of the Stampe will need to be a bit of tuning to be sure !!

cheers

My Stampe wheels are 4.5" and look right to me.

Sarik Hobbies do wheels for the DH82a, which seem to be a spot-on match at 4¾"

The hubs can be sanded to remove the DH logo...

About £25.

For hub covers I used a couple of tins of beerbeerbeer

  1. By the cheapest beer you can find, it will be of very thin aluminium. It might also taste awful
  2. Cut the bottom of the tin away. The dome inside will face outward and the flange can be screwed into the plastic wheel hub.
  3. Recover from hangover.

Mine started life at 6.2kg, covered in `tex. Funny how they put on weight over time. It would take ages with one of these to reach 400ft anyway, and who is going to come along with a calibrated pair of scales and laser range finder?

Depends how light you build it. Mine is 8kg and flies well on a 33cc 2t petrol.

Laser 150-180,, DLE, DA 30 ,Zenoah 38.

Depends on if you like petrol or glow

As your in sunny Cyprus I guess it will be petrol.
