Why Small Airplanes Have Angled Motors 

Well that was more complicated than i was expecting! Interesting

No ads, no silly intros and no intro talk, straight to busyness

Anyone who has ever flown will have heard their CFI scream "MORE RIGHT RUDDER" and "CENTER THE BALL" for their entire first few flights. This is why.

Afaik for some of these forces the correction is built into the airframe, like having a wing with a slightly higher angle of attack than the other. Its very slight tho, so pretty hard to notice

Whoever mixed the background audio was a genius.

Man this person is amazing at explaining stuff

I cant imagine designing an airplane with having to deal with so many factors

Thank you for making this super short and concise I really appreciate that

No wonder! I had a small RC plane with the propeller angled to one side. I thought it was due to damage 😂

This is why I like counter or contra rotating propellers.

this video is just so well made?? i feel bad for thinking this channel is one of those content farm from seeing the logo. i really appreciate the sound design especially in this vid too. heck yeah fluid dynamics

I love this, straight to the point with excellent animations. 10/10

That's why I struggle in IL2 games to stay straight. I wondered why my plane was diverting.

The engine is sometimes mounted on an angle! Because the air spirals around the plane and pushes against the rutter, which would turn the airplane to the lrft. So to counteract this [Repeat from beginning] 😊

Best video on the topic, great job. I never considered the gyroscopic effect before

Thanks for explaining it without any fluff

Such a complicated problem, with such a relatively simple solution. Wow. Learned something new today, already, and it’s only a quarter after 4am.

So thats why i need five degrees of right rudder trim on my p-51 in dcs, thanks

that's not "just a fun fact", that's VERY USEFUL!!!

I love how your videos are super well built and has some immersive sound effects!

Some designs not only offset the thrustline, they also offset the rudder, both in mount point and angle. The Gyroscopic precession you mention is why the WW1 Sopwith Camel was both one of the hardest planes to fly, and also one of the most maneuverable. The engine cylinders spun with the propeller (a rotary engine with a fixed crank, not a radial where the cylinders are fixed and crank spins) The added rotating mass made learning to fly it a real challenge, esp take off and landing. These engines had no throttle, controlling speed was done by "blipping" or switching the ignition completely off. The resulting torque reaction + centrifugal forces of cylinders and propeller caused the Gyroscopic precession that made joystick response totally counter intuitive, and changed depending on air speed. I think the Sopwith Camel took more pilots off the census due to handling errors than combat losses.

Fantastic video, should be shown to all budding PPL pilots

I love the sound effects for some reason

Expected a slow paced video that spent long time explaining something that had simple answer so that one has to skip forward to see the actual cause thumbnail promised. Got a video that explained the thing in the first sentence, and dvelved deeper into other interesting subjecs. Great video! Thanks for not wasting viewers time even for a second!

Interesting, this is actually a whole lot more complicated than when I last tried to make a single engine prop plane in Kerbal Space program, where the primary source of torque was actually from the motor itself, and had basically nothing to do with the propellers.

You dont usuallybjust find videos like these on yt with low views and likes, so im add8ng myself to the roster, and i might recommend this channel. Its a good one!

explained beautifully :)

Nice explanation !

Man you're packing knowledge! Thanks, Absolutely loving the way you deliver it!

This is why we have trims and trim tabs on the control surfaces in order to counter such forces without any significant change on the aircraft's overall structure

Great explainer. This is so complicated and your way of explaining it is very entertaining.

Very nicely explained, both the dialog and the graphics.

The information density in this video is crazy.

The visualization was top tier!

Really nicely illustrated, animated, clear, and concise video!

On the c172 I flew, the rudder was off center, for the same reasons, so it’s either the rudder off the horizontal axis or the propeller

All Radio Controlled single engine airplanes models are designed with 1 to 2 deg of right thrust, just buy one and you’ll see that, even the rubber band free flight models, have that design feature.

Very well explained! We call these the left turning tendencies (for hopefully obvious reasons).

I love these videos, keep up the grate work man 🔥

Great video! Str8 to the point, good animation, good explaining, you got me as a subscriber in no time. 👏🏻

Well that was more interesting than i was expecting! Complicated

Can confirm, works in Flyout! Neat.

I believe the Sopwith Camel was rather famous/infamous for that. Not only its prop, but the entire weight, torque and inertia of its engine added to this. (rotary vs radial engines)

Ive never heard of the engine being mounted off center before. Though on some old warbirds the vertical stabilizer is placed at a slight diagonal.

Thanks! I've always wondered why it points slightly to the left

Short and to the point, nice work

Yo this is pretty cool and straight forward !

This feels moderately unhinged, but i enjoyed it. Liked & Subbed.

Well done thanks !

This video would benefit a lot from having numbers of a list of those factors. There are a lot!

The video was really well made

just a small taste of how complicated aerodynamics can be aha, this is why the people that pioneered airplanes are such geniuses

short and succinct! very nice

I think the P in P-factor is for pitch, not propeller. It’s the difference in pitch between the descending blade and ascending blade caused by the angle of the relative wind.

turn up to go right... reminds of something... classic.

Amazing Video. Please more of that

I dont know why but going through all the various factors that turn the plane to the left reminds me of the "square hole" video. "And what effect does that have on the plane?" "That's right, it turns it to the left!"

Not only fixed wing, the Enstrom F28 also has an angled mast.

First Video i wtched this morning instatly subcribed!this was very interesting

You deserve WAY more views

oh wow youre so underrated

Excellent!

That was amazing....just amazing. Subbed!

There's this new invention out now. Something called a "trim tab"! 😸😸

Holy crap! I had a biplane on KSP with this exact issue! I had to constantly compensate for the plane trying to go left. Wonder if that was the issue all along?

flight instructor here, well done!

I love your narration voice lol.

Can you tell me in which software you make these videos and how can I learn please 🙏🙏

The four left turning tendencies of an aircraft... Pretty neat. All beginner pilots learn them.

Thanks. Now I know how to fly.

Nice education

Meanwhile in Germany: Es ist was es ist. **proceeds to create the Bf-109 which is atrocious when it touches the ground, but allowed many pilots to have great success**

great thx

Super cool!

Radio controlled planes call it add side thrust when the engine is angles 1-2 degrees to the right.

Huh, I'm well aware of gyroscopic procession (give your kids gyroscopes!), but never thought about how it could affect flight on propeller planes!

Yes fun facts!

What video editing software did you use to make this video?

Fantastic

very cool

Some airplanes are worse than others. Taildraggers are very finicky when the tail comes up due to gyroscopic procession. Older airplanes such as Stinson 108’s and Aeronca Chiefs have very disagreeable adverse yaw. Roll the yoke left the nose goes right while the wings stay level. The remedy to AY is to first use the rudder to begin the turn then use the ailerons to coordinate the turn. Cessna engineers solved this problem in their 150’s and later single engine aircraft by designing an aileron with a ridge on the bottom of leading edge that protrudes slightly below the underside of the wing providing increased drag to the wing in the direction of turn.

The majority of the reaction is the torque, the others less so, but a rudder solves a multitude of aircraft design sins. Then a trim tab on the rudder solves the other problems the rudder causes. When in the cruise an aircraft is typically set up to fly straight without any input but very few do. So the trim tab is a bendable bit of metal that you can bend until it all flies straight. Then the next problem is that only works at one power setting....

MS flight simulator has the physics down pretty well.

Than you might as well take a look at rotary engines (le Rhone/Gnome etc)

And this is why the Wright brothers are the legit aviation pioneers. These concepts were developed by them and not Santos Dumont or Arrow.

moral of the story: use jet engines

Wonderful. Loved this video. Short and to the point. You've just earned a subscriber

Who needs an A&P

A video on wake turbulance would be a good fallow up to this one. "why does a small aircraft need to wait so long before /landing/taking off after a large aircraft?"

Gramercy!

It hurts, but cool nonetheless

So this is the reason why my planes can't fly straight in warthunder

You can just use 2 engines

Would any of those issues be solved with another propeller?

what software do you use for your videos?

😂 comical very good 👍

Conclusion: aerial flight is impossible.

That's why i like to fly by flapping my arm incredibly fast, it's a lot simpler

Ah yes, simulator mode in WarT hunder When you kept crashing in interwar plane

Twin props: 😎
