How To CG Your RC Aircraft for Beginners | Quick Tip | Motion RC 

I just use the eraser end of two pencils. More accurate than fingers

Love the quick tips! Been in the hobby 35 years and love it when people are willing to share.

I remember a comment from a fellow RC member when I 1st started. He said, Pete doesn’t matter how heavy the plane is if the CG is spot on it will fly. I like your videos no BS and to the point. 1st lesson for any beginners. CG can’t stress it enough. 2nd, pre-trip your plane before flights.

The most important thing to do before each flight 👌🏻🤩

Beginner or expert always appreciate the information and tips.

Nice work James! 💪thumbs 👍

Great video James, CG is definitely critical, and can change with every plane and wing type, along with gear up or down and battery size and placement, thanks for all these great tips👊🏼👊🏼👊🏼

Another great tip James 👍🏻

A simple tip for beginners indeed James I've been in rc flight about 2 years now have about 15 planes and always use that method before taking flight it never fails for solid cg my flying however sometimes is funny I absolutely love rc 😎👍🛩

Man this was uploaded just when I needed to balance a plane

Thanks for the CG center of gravity tips. Just starting to learn more about rc model plane.

Thank you so much!! I’ve been trying to understand how to properly measure CG of my planes for many years but not sure exactly how to do it.👍

thanks for your explanation. this is the easiest way when we do CG outside field.

Love these tips James , awesome..👊👍

I always appreciate beginner tips because I am a novice with much to learn!!!

Brilliant video.

Great explanation James, lol I have the exact model ND colour scheme of the T33 as well 😁👌

thanks for your tips james,am aviation enthusiast in Kenya wishing to start my RC workshop,hope to communicate wit engineers like you

James I like your approach to move around internal components instead of adding ballast. I know lots of guys that add ballast and it’s really wrong for aircraft. Weight to power ratio is critical and optimization of internal is the best approach. Of course for a single day of strong winds, ballast is okay but I often don’t fly those days and rather take out the boat or buggy!

Some planes, like the F4U Corsair and the P-40 Warhawk, need to be CG’d with the landing gear retracted. After the maiden flight, I adjust the CG based on how much forward stick it takes to maintain level inverted flight. I like to hold just a touch of forward stick so that I can relax the pressure to descend and it reminds me to push harder to go up..

I use little plastic clear pads used to keep items from scratching furniture table tops and glue them on wing surface where CG points are....no need to look at where your fingers are.....just place them on pads....works great.

you said so many times "CG", I'm going to dream of it 😂😂😂 thanks for the advice 👍🏻

Thanks👌👍

I put a button pin, cut the length and push it at the right CG spot on both sides, easy to feel your finger tips where CG is .

Has FlightLine looked at making the T6 Texan II? I think the modern USN/USMC Primary trainer deserves it

Have more painting tutorials lol I want to win your guys March competition 😁

Beginners would REALLY need to know about retracts, extended or retracted. I don't think I've EVER had a manual specify one way or the other. Not even Freewing, always seemed like a significant omission by every manufacturer. It certainly can make a difference, depending on how the gear retract.

My plane seems to fall on either sides, I tried a lot but it doesn't stay a little touch and it falls. Any suggestions for me?

Hi! Tnx for the upload! At 3:52, u say that u have a tail heavy aircraft, but, if you are holding your airplane upside down, is it not actually nose heavy?

I have a p51 Mustang with no instructions ,where should the CG be ?

see where my confusion is, some people say cg with gear down, others say gear up. my next confusion is on higher wing jets like say the f22, yak 130, gripen, f16 etc are those to be balanced upside down or right side up?

what to do for homemade rc aircraft

When is the henglong t 34 coming in stock

Ok what if its nose heavy and the battery is all the way to the back?

you also forgot to mention the retracts having to be up vs down, and also explaining when there is a CG range and also heavier lipos vs lighter lipos.......just a thought.

Is the statement " The main spar is generally the CG " a true statement ? If true dose it hold true for foamies that have spars ?

This is great in the world of i have a manual or its marked on the plane. What about if you have nether??

👍😊

Appeared that the left side of ur jet wing was loose. I noticed a gap after u moved the battery forward! (Or was it just me? 😳)

Does it make a difference whether you don't turn the plane over with low wings?

How do you find CG when it a scratch built Airplane?, I've built a Bi Wing and need to know how to CG it.

HOLA!! EL PESO NO EQUILIBRADO DE UNA ALA MAS PESADA QUE LA OTRA , COMO CALCULAMOS EXISTE IUN METODO ?

Forgive my ignorance but why move an inch forward from the marked CG?

T 33 beautiful

Don’t forget to trim your finger nails before handling foam planes!! Love these videos James 👊👊

👍

The ultimate test is then done in the air: Go to a save height, cut the power, press the plane down at 45° and watch what it does. If it goes back to level flight very quickly, it is too stable and the CG could move a little back. If it slowly goes back it is perfectly stable for most planes. For aerobatic and 3D planes, it should stay at 45° -> Indifferent, that's where the fun starts 🙃 Edit: If it takes the nose down, land immediately and put some weight in the nose

I wish one day an EDF Jet based on a Black Project such as the Boeing Bird of Prey or as the possibly real F-19 Aurora, I would defenitley buy that, so pls...... I beg to Freewing or any developer to do that.

We need FW190D rc with large 3 propellor please! I will pay the $

James the landing gear got to be out... . I had a hell of a time with this plane .

doing CG from manuals is great, but how do i find CG for a homebrew RC plane?

Ther is no way that u can find CG on mig-29 Fulcrum I have done everything

The T33 looks much better in silver! If cg is so important, why do so many manufacturers give the wrong location. Many people have crashed or near crashed planes because of incorrect information.

Think this is called the G spot in Eastern Europe, lol.

Never seen a cg machine?

Please stop shouting, I have a volume control. It’s very irritating, on a positive note, spot on info, as said by another no BS. It’s good to see some one who knows what they are talking about.

The veteran guys don’t have any fingers left to do a manual CG find 😂
