So I've been practicing FF loops and loops from a hover on the sim. I told myself that if I fly my heli "just like in practice, I'll have no problems. Today I pulled the trigger on the real deal with my TREX 600E. I'm running some pretty old Align 4400 18C lipos that are puffy. I pulled off the first 2 hovering loops and landed because the battery quickly lost its steam. I pulled the battery out and set it aside and then heard a "pop". I saw that 2 of the cells had split at the seams. My 2nd battery is the same age and in the same puffy shape but I ran with it anyway; I thought, If I crash, no great loss. Anyhow I tried a 3rd loop from a hover and just as I got to the vertical position and fed in full negetive pitch the battery seemed to loose power. I got back to right side up orientation but I couldn't fully recover and I had a minor crash into some bushes. Damage is a stripped main gear and the elevator servo horn... CHEAP!!! The day was a success since I got 2 flips in... just like I practiced. Next up, new batteries and more practice.

Why would u purposely fly with old puffed cells after just having a short flight with the same state of batteries?..

Becuse...
My main objective of the day was to sucessfully complete a loop or two... mission accomplished without risking a $200+ new battery.

Great job bro I remember the first day I went inverted. Ever since then its been an obssesion and an addiction. Harder maneuvers more powerful helis and on and on and on im sure you know how it is. But I really sugest that you get new batts they will make everything much much easyer to do (more power).

Keep it up man if you got any questions feel free to ask im in vancouver. So if you are going to brooks youll see me there. Its an awsome event.

Assuming your lipo doesn't burst out in flames... split and popping cells? are you kidding? scrap it before it burns your house.

Flips
Dude, welcome to the addiction. It has begun the sweaty palms,shaky knees, the the mini choppers doing 3D in your stomach, and the loss of sleep in anticipation of the next flying session. I have been fling planks and choppers for over 18 years and I can tell you that after the first flight of a new plane no matter what type it is, it all goes down hill from there.Choppers on the other hand are exciting every flight, from maiden flight to 200th flight the pucker factor never leaves you, learning a new maneuver or just flying around is the bombdigity yo yo!!!
congrats on your first loops and flips.
BTW not to be a mother Hen, but!! don't ever fly with packs like you did, forget about your chopper burning up but if they caught fire while you were flying, you or someone else could have been seriously hurt.

Congrats again

Yep, I've said it before, "electrics would be great if it wasn't for the damn batteries!"

congrats on the new manuver

but lets keep it real because this is starting to get WAY out of hand,doing a loop is NOT 3D

So u would rather crash a heli or hurt soeone flying with bad old puffed batteries,,,Not to smart flying a chopper or anything with bad batteries,,,,All because you wanted to save a good battery..?

Sounds to me like the only thing he risked was his heli. It was his risk to take, and he took it and paid the price. Let it go.

imho a loop most definately IS 3d. If you ask me 3d is doing anything that a full scale can't. It all depends on your definition. Since there isn't one written on a stone tablet anywhere, I think he's well within his rights to call it 3d. Besides we all have to start somewhere right? Give the lad a break.

Kentoby: Good job. That's the fun of these toys. There's always something else to learn

Thanks rotormonkey... you get it!!!
It was exactly as you describe. And yea, loops are mild 3D.

A loop isn't even mild 3D.

Nobody's bashing you, congrats on your flipping and looping... but people need to quit changing the definition of 3D flight so they can simply say "I flew 3D today".

I came up with my own definition of 3D that I'll submit here for your consideration.

I believe 3D is any maneuver that to be performed requires the constant harmonized input of three or more controls simultaneously while the maneuver is taking place.

Using this I divided the maneuvers in two categories:

1) Quasi-static controls maneuvers:
Under the previous definition a loop, a roll and a 360 pirouette are not 3D. Those maneuvers are performed by simply leaving one control in a single spot to complete the maneuver with slight and precise modifications to compensate or correct for a perfect maneuver. Even if the maneuver requires several inputs such as in a cobra roll you do them one at a time. This doesn't mean at all that non-3D maneuvers are easy to perform. I actually believe that precise non-3D maneuvers require a very high level of sophistication from the pilot.

2) Dynamic controls maneuvers:
I consider maneuvers to be 3D as those where during the whole time while the maneuver is happening two or more controls are being changed constantly to achieve a smooth harmonized effect.

For instance:
1) A piro flip requires constant moving of the elevator and aileron control in a circular stirring and synchronized fashion while at the same time rudder is kept at a constant rate while the pitch is being changed up and down constantly to prevent it from falling. 3 controls changed simultaneously.

2) A rolling circle requires constant traveling through positive pitch with a bit of left rudder then down to the middle of the travel, no rudder and at this point that the heli is in a knife edge position a bit of down elevator then negative pitch and a bit of right rudder and then back to the center on the left stick and again while in knife edge a bit of up elevator. 4 Controls simultaneously being changed

3) A piro loop requires precise control of the pitch so the model won't lose momentum while at the same time you need to rotate the right stick in syncronization with the heli's orientation to the loop plane.

Using these criteria some maneuvers that most people consider 3D such as a funnel wouldn't fall into the 3D category because they comply with the Quasi-static controls maneuver definition. Now if you take a static funnel and you make it into a morphing funnel then it becomes 3D because to perform it you need to constantly be changing three controls simultaneously.

By the same token, fast backwards flying used to require constant input to prevent the tail from weathervaning. Nowadays with the advent of heading-hold gyros this maneuver changed from a 3D maneuver to a non-3D maneuver.

The same way if instead of a 360 pirouette you start pirouette-flying around then you need to start moving the elevator, aileron and pitch to control the location you want to move the helicopter to and this at the same time synchronized with the heli's attitude towards the flight path.

Those are what I consider the difference between 3D and non-3D maneuvers.

Augusto.

This has gotten silly
We're talking about flying our toy helicopters not curing cancer here guys. One guys 3D is another guys hover... so what?? I just checked Websters and didn't find anything there but I'm open to subjective interpretation though. Again, let's not make a serious issue out of somthing so meaningless in the big scheme of things. If you have somthing respectful and constructive to add, I'm all ears.

Thanks,

KT

I congratulate anyone that gets past hovering so kudos to successfully doing a loop. I would say 75% of the people that ever try flying a heli quit before they can actually hover.

It's a complex, costly, glow powered anti-gravity machine!
