Wing Dihedral for RC Airplanes

Күн бұрынWing Dihedral for RC Airplanes
In this video I will go over what dihedral is for aircraft, why we have it and how wing dihedral should be addressed and applied for RC airplanes. In short, a complete discussion of wing dihedral for RC airplanes.
I first discuss dihedral for full scale aircraft, from Cessnas to B-777. Some aircraft have no dihedral, for example aerobatic aircraft. Certain specialized military aircraft, such as the F-104 have negative dihedral or anhedral. Again, the reasoning for these design choices are all discussed.
I show several of my radio control model aircraft and why I selected the dihedral that I did. This will help you as you either design your own radio control model aircraft or modify other designs.
Wing dihedral is a proven and easy to use technique to provide roll stability for any aircraft, to include your RC models.

Great explanation. The balance between stability versus maneuverability exists in all movement it seems!

Very informative! Could you do a video on thrust angle and wing incidence sometime? Thanks!
@TimMcKay56 Жыл бұрын
Rick: In the cue. I use a bit of right and down thrust, and 2-3 degrees positive wing incidence. Tim

I've wondered why the Wright Brothers didn't go with dihedral and rudder and elevator control, much like birds have, instead of wing warping.
@TimMcKay56 Ай бұрын
The Wright Flyer had elevators and rudder. Wing warping was though at the time to be the best way to control roll. Early WW1 fighters used wing warping (Eindecker III). As wings gained strength and stiffness, ailerons became standard. Tim

Since the tail wing produces downforce, would anehedral tail wing produce dihedral effect, since the wing is essentially upside down, or would the same principle apply regardless of the direction of the lift vector?

Good question, not sure of the answer. 🤔 Tim
@aurelioarenas6293 Жыл бұрын
Great explanation. Quick question, what should be the dimension of the horizontal stabilizer related to the wing span? Could you elaborate how the plane will behave if the horizontal stabilizer is too big or too small. Thanks Leo.
@TimMcKay56 Жыл бұрын
Leo: Thanks for checking in! There really is no mathematical relationship to stab size and wingspan for a sport flyer. If the stab size looks about right, that size should work. If in doubt you can make the stab size a bit bigger. Tim

Hi Tim. I've built a couple of airplanes from a kit. Attempting to build a foamie with your helps. I wrecked a Dynam Hawksky years ago. Broke the nose back 6 inches and the frame in two between the top-mounted engine and the vert. stab. Should I repair that one, or start something fresh like a J3 Cub? Thank you very much!

So I gotta question for ya, I don't have the brain power or knowledge... I'm building a Dumas Taylorcraft 1814 the 40" Blue and Yellow one... Which I'm stuck on at the moment lol... But anyway I'm so tired of trying to collect the old GWS power systems for my projects, that they suggest... There hard to find, and they want to much for each peice... So my question is, with your knowledge, what power system would you suggest? "Looking for slow flying" I know you get alot from Buzzard Models, anything you think would work from there, "like in a brick system"? Pretty much just wanting the whole pewer system from one place in other words... Any suggestions, with your knowledge would be helpful 😊👍
@TimMcKay56 Жыл бұрын
Yote: Best bet is to go brushless with a lipo battery. Figure out what the weight of the Taylorcraft will be. Go to www.HorizonHobby.com for a chart on E-Flite motors, as they list a model weight suitable for that motor. My guess is a 15 amp ESC and two cell lipo about right. Horizon has very good tech support for these questions. Tim

I built a foamy version of the Prairie Bird, 20" wingspan, 3 channel. Trying to fly it, rog, every time it would get about a meter or less, dip a wing, and crash. Pretty much everything I'm building right now is flying like a Charlie Brown kite. Really frustrated with the hobby to be honest.
@TimMcKay56 10 ай бұрын
20" is a short wingspan, not much room for error. Check for no warps, keep weight as light as possible. Tim
@kf4293 10 ай бұрын
@TimMcKay56 I'm probably going to rebuild the wing. AUW was about 133g with a 300mah 2s battery. In hindsight, I honestly overbuilt it. I essentially put a 20g wing on a 3g trainer, and probably twisted or did something in the process. 🙄
