Robin plan reviews
The plans look great! I never expected to get a decent set of plans for that price.

Full size TurboCAD plan for the Robin - printed out on 11 sheets of paper from your home computer
Please note that you will have to have the TurboCAD program on your computer to access the Robin's TurboCAD file. Most computer users have Word installed, and anyone can print the PDF file. Download a free one page sample of the Robin 2's nose section here.

Following are some notes to assist you with your build of the Robin 2 four channel electric RC model airplane. The Robin 2 is easy to build and can be finished in a weekend. The Robin 2's RC airplane construction is primarily of 1/8” square balsa with some 1/8” sheet balsa and light plywood in selected areas. The Robin 2 is designed for a hand launch and has no landing gear.

The plans show you can purchase the electric motor and radio equipment for the Robin 2 from Horizon Hobby. All of the Robin’s electronic hardware comes from the E-Flite 4-Site micro biplane. You can buy the components individually, or just purchase a new or used 4-Site and harvest the devices from the foam plane. At my local flying club, a friend had an older 4-Site he was no longer flying that I used for the Robin 2 motor and electronics.

Keep the Robin light
Keep the weight of your Robin 2 to a minimum. The model is light, and you do not need heavy balsa for strength. Choose the lightest weight balsa for tail surfaces, as the tendency is for the Robin 2 to come out tail heavy if you are not careful. Ensure you balance the model at the center of gravity with the battery installed in the nose section. I recommend that you glue a four inch length of 0.030” carbon rod to the center portion of the wing leading and trailing edges for added strength in this important area.
I employed no offset for the thrust lines and the model flies well. Use a lightweight iron on covering and be careful as you shrink the covering to not warp the Robin’s frame. The balsa structure is strong enough to handle the shrinkage, but be careful as you apply the heat. After the wing is covered slide it into the slot in the fuselage and glue in place. Use this same process for the horizontal stabilizer. Note that the fin is built as part of the fuselage.
Once the wing is installed, attach the ailerons with clear hinge tape. Mount the elevator to the stabilizer with the same method and then attach the rudder. Be sure to bevel the forward surface of the ailerons, rudder and elevator for full range of throw before you cover them.

Electronics are easy to install
The electronics are easy to install, and should be kept as far forward as able to help with the center of gravity location. I used double sided foam tape to attach the ESC and two aileron servos to the Robin 2.
The motor is glued onto the 1/16” ply tabs. Carve out portions of the nose balsa area to accommodate the plastic motor mount. I used craft store paint on the mount’s bare wood areas to blend in with the Robin 2’s film covering.
The Robin 2 is an agile and responsive flyer. You can fly your version indoors in a larger setting, as well as outside as a park flyer under calm wind conditions. I do recommend a small amount of exponential control be used to smooth your flying when the transmitter control sticks are near center. As you can see from the full size CAD plans, the Robin 2 very easy to build and is a great way to start constructing your own RC micro airplane.
