Which foam is best for RC planes?

Which foam is best for RC planes?

Depron is a trademarked brand of closed-cell extruded polystyrene that is sold as wall insulation and flooring substrate. Depron is also marketed for arts projects and RC modeling. There’s even a variety of Depron that is specifically manufactured for RC use called Depron Aero.

What is a good wing loading for RC planes?

Wing loading is the load sustained by the plane wing per unit area. It determines how much load your plane’s wing will be able to accommodate. RC plane wing loading depends on how big of a plane you want to make. But for an average sized RC plane, wing loading of 5–10kg/m^2 should be enough.

What kind of foam are RC airplanes made of?

The principal foams used in building rc planes are Expanded Polystyrene (EPS), Expanded Polypropylene (EPP), Depron and Expanded Polyolefin (EPO), the latter, EPO, being the most commonly used. EPO foams are denser but more lightweight and have a glossier surface finish than even perfectly molded EPP and EPS foams.

Whats a good wing loading?

Wing loading for birds is generally between 1 to 20 kg/m2. Twing lohe maximum possible wing load before a bird is unable to fly is about 25 kg/m2. This is when the bird is too heavy for its wings (like the kiwi, which has tiny wings and a large body mass).

What is a high wing loading?

With a higher wing loading, a given lift-to-drag ratio is achieved at a higher airspeed than with a lower wing loading, and this allows a faster average speed across country. The ballast can be ejected overboard when conditions weaken or prior to landing.

Can you really fly?

Humans are not physically designed to fly. We cannot create enough lift to overcome the force of gravity (or our weight). It’s not only wings that allow birds to fly. Their light frame and hollow bones make it easier to counteract gravity.

Which is the best brand of RC flying wings?

Carrying reputable and popular brands such as Freewing, Skynetic, and Nexa, Motion RC provides a sizable selection of graceful and stunning models in stock on our website.

What kind of foam to use for wings?

Don’t use the heavier (“pink”) foam for flying model parts, in general, although it’s good for making plugs. Urethane foam is also fairly light, easy to sand and cut, and has the advantage of resisting most glues and solvents.

How do you make a foam wing core?

Making Foam Wing Cores is relatively easy, using styrofoam. There are several commercial devices made for cutting foam wing cores and other parts. The basic process is to produce templates first, (usually a “root” and “tip” template) then use the electrically-heated hot wire to cut the basic wing shape out of the foam.

How do you make a control horn for a foam wing?

A strong and simple control horn can be made by threading a nylon aileron connector onto a 6-32 machine screw, then screwing it into the dowel. When the epoxy is cured and the wing is sanded to shape, you now have “built-in” control surfaces! Later, when you cut them out, they will fit perfectly!
