You can stuff those pencils in your nose and pretend to be an elephant too lol 🐘

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.

Beginner or expert always appreciate the information and tips.

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👊🏼👊🏼👊🏼

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

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 😎👍🛩

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

Nice work James! 💪thumbs 👍

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

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

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.👍

Another great tip James 👍🏻

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

Love these tips James , awesome..👊👍

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

Brilliant video.

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

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 .

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!

Thanks my man!

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.

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

Thanks👌👍

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

what to do for homemade rc aircraft

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?

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

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?

@MotionRC

2 жыл бұрын

No. regardless if the plane is upside down or right side up, the weight of the tail is being pulled down by gravity. That's tail heavy

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

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.

@mrparamedico25

3 жыл бұрын

Personally, I always look for the CG with the retracts below, because when you land your tail gets heavy in many cases

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?

@txkflier

If the CG moves toward the tail when the gear is retracted, do it with the gear retracted. The plane is more stable on your fingertips if the vertical CG location is below them..

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? 😳)

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

@MotionRC

3 жыл бұрын

If you had nothing from the manufacturer regarding CG, then the spar would be my first choice to start from. Then I would apt to fly it nose heavy of that position first and work my way from there

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

He’s using the batteries weight to change and find the balance point/CG.

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

in theory no, but having the weight below the wings is easier to manipulate

T 33 beautiful

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 thought the 45 dgree test was done inverted? if the plane immediately nose dives its nose heavy, if it climbs its tail heavy, and if it has a slow nose down like quite slow, thats a good all around cg

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.
