Does anyone know of a 1/2 A Pitts biplane kit or plans with a span of approx 22 to 24 inches? I have seen a Royal Pitts but it has a 30 inch span. I would prefer it to be a bit smaller so I can use one of my TD .020's on it.

If you can find plans, the Goldberg .60 sized Ultimate Bipe scales down to 24 inches and makes a nice flyer with a Norvel .074. You'll need to rethink the construction details to keep it light, but the basic layout works really well.
I used 1/16" diameter bamboo skewers for the cabane struts and a real long drill bit to drill the holes between both wings in 1 shot while the plane sat in a jig. The actual drilling and skewering was real easy after just a little time was spent to temporarily hold the wings and fuselage in place.

I made this one with foam and flew it at SMALL about 5 years ago. Fluging weight with a GWS S2 minus battery is 5.9oz. May have the drawings around if interested.

If it's a Pitts you want then get a Herr Pitts Special in the FF section at Sig. It's 24 inches and much more scale than the one meant for RC, which is 30 inches anyway.

Lots of people convert these to electric RC, but I'm sure it would suit a TD 020 extremely well with the proper mods.

This place has oodles and a few F/F Bipes that are meant for rubber and in the 24" range. Pee Wee or TD should fly them when beefed up in strategic areas.

I have been Jones'in for .020 size Bipe for a long - long time. Stumbling block for me is mounting a removable top wing and cabanes that don't tear the wing to pieces in a hard landing. I'm all ears if you all have Skaliwag proof solution.

Hi Scaliwag,
I'm currently building a 25 1/2" span Sopwith Swallow for FF, it's a Bill Denis design,one
of our UK greats. Bills solution to your problem was to build wing cabin struts and a
section of top deck of fuselage all in one piece, which would, hopefully, knock off in a free flight arrival.
I probably got plan from Outerzone so it might be worth your time to do a search for it to see his neat solution.
The Sopwith Swallow is a parasol wing rather than a biplane of course.

This shows an 049 installed but the wingspan is less than 24" . I believe that an 020 would work . Othersmight know better . ... D.J.

It might not look elegant, but use nylon screws that pass completely through the top wing and thread right into the framework that is below the wing. Balsa N struts with hardwood blocks mounted tight against the bottom of the top wing could be shaped to look not too ugly and thread the hardwood for #8-32 screws.

This place has some nice small stuff. http://patscustom-models.com/index.html

It's controlline, but could be easily converted if built very lightly. Span is 25".

Super basic, not too very scale and rubber power, but it is a Pitts bipe with a 24" span!

I think there are about a dozen of us who are more interested in this than the original poster!

LOL the OP asked for a KIT or PLANS for PITTS biplane. only one guy did that. The Herr pitts is a good choice and I even think Peck Polymers had a Pitts with a 18" span.

MJD

My Feedback: (1)

Yeah you're right, even me. I know I read too fast, and I read it as "looking for a biplane for a TD .020"..

Potential convert?

MJD you're correct it wasnt PP it was Dumas. I would like to see one of these fly in a full house set up with a throttled .020.

It seems a better size for any level of performance from an .020. 18" sounds small but for a Pitts it ain't.

Wasn't there an Andrew on the west coast who had a web site with Bipe plans. He also had the PDF tile program. Can't recall his site name.

Also hosted the 1/2a design contest results for several years.

Found it. Andrew Donatelli

Later: Plans seem to have disappeared from his site.

Here's a 18"ws pitts http://www.dumasproducts.com/product...roducts_id=703
And its cheap enough to buy for the plans, then enlarge them.

The AMA also has numerous plans of almost any biplane in your size range.

Thanks for pointing me back to dumas.....love their staggerwing.

Whatever happened to the guy that was you tubing a coroplast bipe?..I went and bought a sheet of it and never saw part 2 or maybe it was three? Anybody build one of those for the 049 product engine...Rog

I think that the last part still isn't uploaded, but an other fellow has made his own buildvideo to complete the one Bruce Simpson started on. You'll find the link in post #58 of this thread: www.rcuniverse.com/forum/m_10446044/tm.htm
