Wing Dihedral for RC Airplanes

[@yodecaf]

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

I'm still building my plane . All these vids are helping a great deal. Thank you very much.

[@TimMcKay56]

Glad to help!

THANK YOU I HAVE LEARNED A GREAT DEAL FROM WATCHING YOUR VIDEOS.

Great information and background! I love that you went all the way back to the start if rc planes! I learned some new things, thank you!

AMR: Glad you enjoyed it! Tim

[@randall4411]

Good video Tim . Dihedral and incidence . Two of my favorite words . Center of gravity is my # 1 favorite .

[@TimMcKay56]

Randall: Good choice! Tim

Hi 👋 Tim , you providing good informative stuff 👍 please continue with it 😉

[@gameoflife3530]

and I have a favor to ask can you give me your oldest flight controller ,here in India 🇮🇳 it's so costly for me to afford

Nice video Tim.

David: Glad you enjoyed it! Tim

[@rickrader1649]

Very informative! Could you do a video on thrust angle and wing incidence sometime? Thanks!

[@TimMcKay56]

Rick: In the cue. I use a bit of right and down thrust, and 2-3 degrees positive wing incidence. 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!

[@TimMcKay56]

Willard: Nose is tough to fully repair. Maybe start a new project. 😊 Tim

[@willardpearce8218]

@@TimMcKay56 Thank you, Tim for such a prompt reply! I'll take your suggestion to start a new one. Do you have any videos on building a J3 Cub, or some plans? I appreciate you help. Willard

[@TimMcKay56]

Willard: No plans, yet for a J-3. 😊 Tim

[@calimlimfrancisnoah5352]

Hey Tim another question on delta models, which is better the push or pull motor?and what is the difference?

[@TimMcKay56]

No difference, both work fine. 😊 Tim

[@aurelioarenas6293]

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]

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

[@rolandotillit2867]

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?

[@TimMcKay56]

Good question, not sure of the answer. 🤔 Tim

[@mikenadler7118]

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]

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

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]

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

[@yotehunter3468]

@@TimMcKay56 Ok I'll go look, thanks...

[@yotehunter3468]

@@TimMcKay56 Forgot that's actually where I bought it, there suggestion was a GWS setup 🤦‍♂️

[@kf4293]

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]

20" is a short wingspan, not much room for error. Check for no warps, keep weight as light as possible. Tim

[@kf4293]

@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. 🙄
