Balsa USA Smoothie RC Plane Kit Build No 38, install CA Hinges

In this video I continue with my build of the Balsa USA Smoothie and show how to install CA hinges on an RC plane. I show how to cut CA hinges, how to slot control surfaces for the CA hinges, and gluing of CA hinges. Always use thin CA to glue the hinges.

The Balsa USA Smoothie kit is a 40 class (size) sport rc plane and has been around for a long time and is still readily available on the Balsa USA website. Balsa USA also has a larger version of the plane called the Balsa USA Smoothie XL. I will be using an OS Engines 46 AX2 glow engine to power it and Futaba S3004 servos, receiver, and 6J transmitter.

For this balsa kit build I use traditional rc plane kit building techniques. In each build series episode I will focus a different aspect of the build including the wing, fuselage, tail section rudder and elevator, rc engine mount, landing gear, tail gear, rc glow engine set up (OS Engines .46 AXII), fuel tank, servos and receiver (Futaba), Sullivan control rods and horns, Monokote covering, carving and shaping wood, using CA glue (Zap CA glue, Starbond CA glue), epoxy (JB Weld, Bob Smith Industries, Z-poxy finishing resin), Titebond Wood Glue, tools and everything thing else involved with building a radio control plane kit (RC Airplane kit). I named a bunch of brands here, but there are plenty of other to get the job done.

I have been building, flying, crashing, modifying, and repairing radio control planes (RC Planes) for many years and enjoy sharing what I do with the radio control plane community, so I started RC Plane Tech channel for fun. I am not an expert, there are many different techniques to building radio control planes. A good way to learn about flying and building rc planes is to see what others are doing, that’s what I do and that’s why I like to share what I do. Thanks for watching my channel. Have fun!

    I usually don’t use CA hinges and replace them with pin or flat nylon hinges but with a recent ARF I bought I just used their CA hinges. Probably strong enough for a Sig Kadet Seniorita. Those scissors look like they could snip off fingers! Beefy!

    That beetle is known as a "Stink Bug". Go look up why they got that name😂
