Lol... Sorry I see my question wasn't quite clear.
On the plans there are 3 wing templates.
I imagine there should be 4.
Am I meant to mirror the one?
Or is there one wing half actually missing from the plans.
Thanks Matthew.

I think all four wings are there in the plans. Take another look and see. The top wing is glued and taped together.

Its a sweet looking plane. I've had mine for over a year and its still going strong after many hard landings and the upper wing being ripped off in flight after some ill-advised acrobatic flying. Have fun with the build!

Sweet. So it doesn't do aerobatics well? 😂

What setup are you using?

A motor from a C pack kit, with a 2200 3C battery. I think mine balanced with a maybe 1/2 oz of extra weight. It was cool when the upper wing came off, and it landed just fine. It's not super with rolls (it IS a biplane after all), but if you turn up your ailerons, it'll do some tricks.

Ok cool. That's exactly what I'll be running.
Just can't decide whether to put my 2217 1250 kV (cheapo orange motor) motor or my 2215 1250kv motor (original power pack C)

I'm about 6 hrs into the build, impressed how things are going together, have every thing cut out, have the main fuselage together, starting the skins. Very much enjoy your since of humor in your build video

Moving right along. Look forward to see more progress.
Any ideas along the build would be welcome as well since this looks too good not to build.

Just finished up , been a week three four hrs a night. Build was a little tedious at times but just took extra time fitting and forming ,the big skin came out a little off at the wing saddle so I added fairings. Little concerned at my cg I'm 3" from leading edge of top wing, if anyone has built and flew one would appreciate your input

It looks so nice pulling up sharply and banking after a long low level pass, just like I remember how the converted crop dusters did when I was a kid. I really should add a bunch of wires using black elastic bead cord, to hear the wind whistling thru them.

Just build the rear end light as possible, to avoid adding lead inside every cylinder like I had to do, but flys fine anyway (c-motor).

CG located right on the leading edge worked great with mine. Found location in some balsa plans on Outerzone. Wing section would normally be semi-symetric, so I needed a bit of down trim, but CG feels good.

Thank you for your response, this will ad a layer to my security blanket . This will be my second attempt at the pt, my first was a balsa build that ended tail heavy ,was extremely lucky to get it back on the ground on its maiden , haven't tried to fly it again after adding tons of weight to the nose ,just can't believe it will fly decent. Was glad to see this build here it's one of my favorite planes. Thanks again . Your build looks great.
 
Here is my version:
2830 motor with a 9x6 prop using the 2200mah Ovonic 35C 3 cell battery
Landing gear wire was the handle from an old home depot bucket with 2.5" Dubro Low Bounce tiers
Steerable tail wheel assembly from Amazon
3D printed parts include the 7cyl radial engine (weight-96g), motor fire wall, wing struts, control horns
Vinyl decals designed in inkscape and printed on home printer
All parts covered with colored/clear packing tape using the Experimental Planes technique
Lower wing is held on with 2 nylon toilet tank bolts/nuts
The weight of the 3D printed engine perfectly places the CG right at the leading edge of the lower wing
Flying weight is 1.190Kg (2 lbs, 10 oz)
Now if these Central California coastal winds will die down a bit, I will maiden her.
The last pic is the real plane I modeled the livery from.

Wow, another stunning example. These last couple of planes are gorgeous.
Well done guys. I am inspired to put out my best work now.

Thanks for the great plan. For some reason, I have to make all the strut support for the upper wing 1 1/4 longer to get some clearance from the fuselage

Looks to me like you got the cabane struts attached in the wrong place. They should attach to the top of the fuselage, not the sides.
