I actually have two more sets of wings to build to really make this an EVA (Extremely Versatile Aircraft). There's a sport low wing set, and a 3D set, but the biplane is finished. I've already started on the 3D wings a while ago, while I was waiting on a set of wings for the Bipe (I made two of the same side lower wing halves by accident). Anyway, that means more covering and painting later down the road.
I followed the instructions all the way up to the covering, and then I went on auto pilot with the assembly (pardon the pun). So here's the rest of the Bipe build:
Starting the upper wing:
Leading edge.
I didn't take any photos of installing the "D" box. I'll try to remember to do that as I complete the other sets of wings. The important thing to remember about the D box is that it will stiffen the wing, and if the leading edge is not laying flat on a flat surface, you might twist the wing beyond the point of repair (in other words you'll need to pony up for a new set of wings). As the manual suggested, I raised the trailing edge of the wing so I could tell if the leading edge was laying flat.
So at this point I'm done with the build, and I'll pick up where I left off in the Oct. 27th 2014 post right after the motor, motor mount, ESC and Rx install.
The first thing I'm going to do is glue up the canopy. I don't use CA on my canopies I use a specific glue that is for canopies. It dries clear and doesn't frost like CA. The drawback is that it takes hours to dry, but I haven't been in a hurry since I started this project, so I'm ok with that.
This stuff lasts a long time. I've had this same bottle for a few years, and the bottle before that as well.
I used the rubber bands instead of tape because they serve the purpose and don't leave any residue behind. Below: I hit the front really heavy with the glue. This stuff peels up without taking the covering with it, so you can be fairly liberal with it. Looks like crap now, but you won't even see it in 24 hrs.
Below: I left enough to sticking out just in case i made a mistake. I'll trim it with a knife.
Above: I set up the control horns with mini E-Z connectors. This is where I deviate from the instructions. You can read a couple of posts prior to this one where I questioned using two pieces of metal held together by heat shrink and CA. I mean I guess it works because the manual suggested to do it, but it seemed sketchy. Some people think E-Z connectors are sketchy, and I'd agree, but I've used E-Z connectors before (read: I'll try this later, just not now).
Anyway... the main reason for showing this picture is that I set them up before I glued the horns in. The predrilled holes were not big enough and doing all that work after they were glued in would have been a pain.
Above: I didn't use CA to glue in the horns as suggested, and personally, I would have used Gorilla Glue (original formula) before I used CA. I just feel better using epoxy over CA in this case.
Below: Control horn and wing mount placement:
At this point its time to install the servos in the wing, and man... that was a pain in the ass. I forgot how small the pass through opening in the wing was.... like trying to thread a needle blindfolded. Once I got the servos installed, It was time to put it all together.
Below: The assembly
Above: There are only two of these screws in the kit, which is a shame, but you need to leave these for your wing bolts.
Above: Again i didn't use CA, I used 30 minute so I could make adjustments. Also I wanted to install the lower wings first so I could sight over the Horz. Stab and make sure it was level with the lower wings. The 30 minute epoxy gave me the time to make sure my tip distances were equal and that the stab was level with the lower wing. You want to make sure that you cut the covering off where you are applying glue.
Above: Same with the V-stab.
Above: I've got both canopy magnets in the fuse and I'm applying pressure so it will make a pressure indent on the bottom of the canopy. This way, I know where to install the magnets.
Above: If you don't make this recess, your canopy will sit too high. Below: Magnet epoxied in

Above and Below: It's a good idea to use thick CA in the holes for a little added security (as shown above). So make sure your upper and lower are where you want them if you do that. I'm sure that you can adjust if you needed to, but it will be more of a pain to do so after the glue dries. Below: Make sure you use thread locker on all metal on metal, including the E-Z connectors.
