The arms are 5/8th inch square rods from home depot. I used ONE 36" piece which was cut into an 18" front arm and two 9" rear arms. The cost was $1.98 for the rod. It is some sort of unknown hardwood from China, which I found in the moulding section of the store.

The body is made from birch ply from Michaels.

All up weight with drive and battery is about 950 grams.

Motors are SunnySky X2212-1250kv with 20amp Afro ESC's and a KK mini flight controller.

I use the standard X settings in the KK and they seem to work fairly well. I did make the front motors 100 and the back motors 90. This helps it to take off level.

My P values are about 120 on pitch and roll and yaw. I left the "I" settings alone.

Had one motor spinning slower than the other, making flight very unsteady. So, I removed both motors with a razor blade motor and was able to mount the other working motor in the nose. It was easy to mount with the some hot glue to get the right down angle. I have left thrust angle also b/c I am using the counter rotating motor in the nose. I covered the holes in the "pontoons" from where the motors were cut out by covering the holes with blue painters tape and painting the tape with some gray acrylic paint from the local crafts store (Michael's). The battery cable was fed through the body and a hole I made in the bottom. I just hot glued the original battery velcro to the bottom of the plane. It looks cool, we will have to see how it flies.

I love this little plane. Admittedly, at first I was not that crazy about it. I thought it was too small at first glance. The first few flights were a bit uncomfortable as I got used to flying a cub. Ohhh wow do they fly differently than any other plane. But once I got used to it's flight characteristics (ie lots of rudder steering and potential wing dropping tip stalls in slow turns), I got to really liking it. Especially now that I upgraded the motor and ESC. It really seemed to benefit from some more weight in the nose. It also for some reason seems to fly better on the stock prop than anything else I have found so far (and I have boxes of props and boxes of motors). In any event, the motor I chose was an sk3-3542-1000kv from HK, and a HK 30amp Blue ESC. It pulls 34 amps static with the stock prop, which should be fine since the ESC has a 40 amp burst.

Anyway, here are some pictures. If you get the chance I recommend giving this plane a try. It's a blast. The SUPER SHORT full-flap take off's are the coolest thing. And the SUPER SLOW full-flap landings are quite a sight.

A quick note: You can use 60 degree or so full flaps for take off, but it's best to use half flaps for landing. On two occasions, over the course of 2 weeks of owning the plane, the use of full flap landings resulted in the plane corkscrewing into the ground, both of which required me to glue the entire nose of the plane back on. The plane stalls really easily with full flaps and is almost completely uncontrollable when that occurs.

On the Elevator and Rudder I hot glued in a TGY-390DMH High Performance MG Digital Servo from HK.

I used thicker control rod that I picked up at the hobby store and some Great Planes screw-lock pushrods connectors (see picture).

On the rudder, to allow for the natural angling that occurs when the servo moves, I made a Z bend in the control rod with Z bend pliers (see pictures) for where the control rod goes into the Rudder Control horn.

The elevator servo was supported with some sloppy basswood pieces b/c I cut the hole too large, but it works great....Continue Reading

These were cut from Elmer Foam Board.

Here are templates of the smaller fences, these are the ones I used in the videos.

And some larger fences that I haven't tried yet, but am installing today.

I scanned the Wing Fences as PDF files to print on USA Letter Paper, and also included PDF scans that will print perfect copies on International A4 paper.

Best of luck and happy flying.

This is the same plane detailed in my blog. :-)

Made from 1x6 Cedar Boards, book rack system from Lowes or Home Depot, and foam pipe insulation to protect the wings.

Just some brushed on Acrylic Paints from Michaels.

I liked the plane so much I reconfigured the original Sukhoi to match. So it now also has the larger SK3 4240-740kv motor and a 6" diameter plywood firewall. I actually went about a centimeter shorter on the nose. We will see how it flies. The rudder and elevator were already super responsive as compared to stock. I actually just finished reprogramming my DX7 to reduce the throws in low rates on the rudder to keep my KE spins from falling out into Blenders.

I ordered a spare fuselage from Dynam when I tanked my other Sukhoi, so I had this spare fuselage laying around. Anyone who has ordered spare fuselages knows that they don't come with anything installed - no servo plate, no motor mount, no plastic pieces to mount the wings, no plastic nuts to mount the tail. As such this had to be a custom job just to get this plane together. Things I did:
1) Bought a piece of Bud Nosen 1/8th inch Aircraft Plywood and cut it into a six inch circle to match the diameter of the Sukhoi nose. Then, with a butcher's knife, I cut the entire nose off of the plane. I actually shortened the nose by about an inch. Then I lined up the motor mount on the plywood, drilled the holes, and installed 4-40 blind nuts to mount the x-mount.
2) Then I hot glued the 6" Plywood Circle to the nose of the plane and cut back the cowling to where it would line up with the 6" circle. Then I hot glued the cowling to the plywood. I of course mounted the motor and drilled holes for the ESC wires.
3) Rear mounted the Elevator and Rudder Servos. This made it more tail heavy but that was OK b/c I was going to run a heavier motor, an SK3 4240-740kv which is 50 grams heavier than the stock motor. It all balanced out fine. I actually run a 3000mah 4s and have wooden dowels hot glued into the inside of the plane and Velcro straps to secure the battery slightly further back.

This was the most time consuming plane I have ever put together. Hopefully the maiden flight will go well. Anyway, it balances perfectly with a 3000 mah 4s battery. I made a custom battery tray for it out of basswood which was supported by layers of blucor foam (actually green from Lowes). I am using the original motor and motor mount from a Dynam Sukhoi and a 13x6.5 prop. The motor mount is screwed into the orignal gas motor supports using 2" wood screws. Then I made some blucor insulation support for the upper and lower sections of the motor mount, those are hot-glued in. The kit, which I got for free from a neighbor of mine, was missing some parts. Most notably, it was missing the part that allows you to hook up the nose steering. So, I custom mounted a servo nearby and hot glued a wood dowel (with a servo arm screwed and glued to it) through the spiral spring of the front landing gear. Hopefully it will stay together. :-)

I did some video editing stuff to zoom in at certain points, added some music, and some film effects at the start and end of the video. Anyway, I hope you like it.

As an FYI, the music in the video is a karaoke version of the song and is definitely not the original band. But it works for the video and shouldn't cause any controversy.
