I would like to build a biplane.
does anyone have a source for plans of typical sport style biplanes, or have a plan set they would sell me ?. looking for a big plane,... at least 5 foot wingspan. build complexity is not an issue,... I am an accomplished builder with every wood working tool imaginable and have read blueprints (some so big you roll them up and carry them on your shoulder) all my life on my job. I have a couple sets right now, Astro Bipe, Ultimate, but am always looking for others to consider.

What about a bi plane like the Weeks Solution or the Solution X modeled after Kermit weeks?
I have built and flown 7 of them it's a great airplane.

Try the AMA. They have a lot of plans.

find an architectural design firm. they are accustomed to copying large prints. I had a few boat plans copied and enlarged for the few dollars that the vellum cost in the past. most of them have a copier that can handle 5 or 6 ft. wide sheets. if I may ask,....what did Kinkos want to make copies ? IRC, a few years ago, I had a 1/2A F1 Rivets plan (Sump'n Else) that I printed off the internet expanded to 56" wingspan at a Kinkos near me, for around 18 bucks.

holy molly,..... yeah, that's crazy !..... there's just no reason for it be that much ! I wonder if maybe that Kinko's has to export work that large (?) I would think they all have the same capabilities,.....but maybe not.

You could not go wrong with Chuck Cunningham's original Lazy Ace - the 76" version, from RCM magazine. Plans are available on the web as well as *bay. Great fun to build and more than fun to fly.
I've built three.
Good luck

DRCRAIG, I m leaning towards that plane in the 76 inch size !.

You can just take a picture of the plans with your phone. I was told there is a phone app made to turn your phone into a scanner. It will square it up and some even convert to a doc, or pdf. I have not tried it yet, just thought it would be pretty affordable... FREE

How about a three in one, low wing, parasol, & biplane, all using the same fuselage and 2 sets of wings.
This was designed and drawn by the late Jerry Behrens, it is called the JB Special.


I think I have the plans scan on file, and :Hemi-Killer" here on RCU can print them up for you at a very reasonable cost.

Lots of great possibilities. There is an old Ziroli Pitts from RCM, plan file available on Outerzone. For similar scale, but not the familiar Pitts, I have plans, construction article and fiberglass cowl for a 1/4 scale Smith Miniplane which were originally from this source...
Smith Miniplane(s) - Leisure Rc Models

It has a 51 inch span and won quite a few contests back in the day. The website doesn't tell you, but the fuse has been narrowed slightly for performance on the 60 size engines in use at the time.

Let me know if you are interested. I'd let it all go for much less than the original price.

I have always been a fan of the Aeromaster bipe.

I like the look of it too Dr.
I have a 25cc brushcutter engine I am converting to spark ignition/ petrol and modifying to run on AvGas.
Do you think this size engine is big enough for the 76 inch version? Or should I scale it down a bit?
I have other builds in the front of me, so this is only dreaming stuff at this early stage.

Jim - I would expect the 25cc to do fine. I have read about several guys using the Zenoah 23 with good success.
Have a happy Thanksgiving. Oops - I just noticed you are in Australia. G'day Mate!!
