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.

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.

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

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
@txkflier 3 жыл бұрын
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..

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
@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

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
@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

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
