What is the difference between 3D and 4D? They are both aerobatics, right?

what mean is 4d? pls

3D aerobatic flight includes flips, rolls, piros, and/or combinations of all three with little or no ground speed. 4D doesn't exist, unless you count flying through wormholes for the entertainment of other galaxies. Some guys who quickly shake the cyclic stick (it averages out) through maneuvers for the resulting blade sound effects seem to think that they're in another dimension but they're really still here on Earth the whole time. It's fun to watch, but hard on blades, bearings and dampeners.

You mean the "crack" movements, right? Yeah, maybe it sounds nice but in fact the heli is suffer.

Where did you hear the term 4D? Other than some plank manufacturers, that decided to name their planks 4D, I have not heard the term before.

4D usually refers to foamie planes with reversible pitch propellers.

The blade holders on a "4D" plane are pretty much just like the head of a heli.

Usually the TX is programmed like a 3D heli. With the throttle stick mixed with the blade pitch.

The planes can stop and reverse in mid air, but they are not stable going backwards so they naturally flip and change direction really quick.

Here is a good 4D demo http://www.pauzuolis-rc.com/Videos/ArrowMVPP_DP.wmv

3D helicopters are already "4D" since they can go backwards and forwards, and change blade pitch...

So 4D exist?

I just saw the video. DUDE, it's awesome. Never saw something like that. Really weird

If reversing the pitch is all it takes, then we've been flying 4D all along!

Yeah, i understand now Thanks for the answers guys. My knowledge keep growing in everything you posting, SO keep posting
