Ok I have a good question for you all. What is the difference if the flybad is above or below the main blades. My x cell has them below main blades, and my son's new raptor 30 V2 has them above the main blades. Does this effect handleing? does it effect anything in any way? Im still learning and i was just wondering. Like to hear your theroy.. Thanks

it used to be thought that the shorter lengths of the control rods

made for better control with an underslung flybar


also,,,,,,,the early 3Ders of twenty years or so ago thought

that they were more stable inverted with the underslung flybar

ive had many of both types and cant tell the difference

I've had flybars above, below and inline (only one per heli ) . The heli that happens to fly the best has an underslung flybar (TSK Mystar 46), but one has to be the best flying heli and I doubt that it's down to the flybar location .

At the end of the day , it gets dark .

Boatman,

Fine, this is why MR has a search function on the forums. I don't see where my answer is less fun because I pointed out that this question had been asked before. In any event, look at the other threads and there may be additional information that isn't presently being discussed. As far as liking or disliking the question what does this have to do with pointing out that the topic has been thrashed and only a simple search would have revealed that? Besides, I answered his question which is more than you did Mate.

TMoore....Amazing, not only did your first response suggest you were ignorant, you managed to confirm it with your second. Courtesy is cheap and if someones question irritates you because of repetition, just don't respond....it's as easy as that!

He who dies with the most toys is the winner!

darrens,

This forum is open to all opinions, even yours. Instead of engaging in thread drift answer the man's question. I did.

Stephen,

Thanks for the support. I'll return the favor. I wasn't being vindictive just informing Cobraman that the topic had come up before.

Frankly when the disk on my X-Spec is hauling ass at 1800 rpm I don't pay much attention to which side the flybar is on and the same goes when I fly the Raptors.

TM, I read your post 2 times to get what you meant. It may not be what you said but how you "type" it in a forum. I would simply suggest you read each post you make and say to yourself, "can this come off wrong". After reading your further post you make yourself more clear you wasn't trying to be a jerk. Maybe you could have posted something like this:

Sir, this topic has been discussed many times before and you can find many opions at the links below:

you can find answers to question simply by using the "Search" function listed at the top of the main page. Happy Hunting

Cobraman.......

LOL.....Don't worry about some of the replys...Let it bounce off bro!!

Some guys around here tend to take themselves a little too seriously!! .And they forget that this is all about learning....

If you want to stay here on RR, be prepared to deal with all types of people. Cool, rude, polite, sarcastic, and everything in between.

Look at it this way.....today you learned about the "search" funtion, and about the difference between flybar position.

Just let them complain...............and it helps when you send them a P.M with just this smilie:
That makes me laugh..........

Don't let this discourage you. While most people on this forum honestly want to help you, you have a multitude of personalities to deal with here.
I applaud TMoore for taking the time to provide the links. As to his approach it will undoubtably upset someone though I don't think it was his intention.

Hang in there.

As to differences in under/over slung flybars, I've nerver noticed any though I'm sure an Aeronautical Engineer with a Phd could tell you the difference.

Go out and fly and just have fun.

Anyone that knows me personally, knows that it's all in good fun. If you're going to fly helis you have to take as good as you give. If you can't take a little sarcasm, a little heat from your friends, a little good natured ribbing, well you need to take up another hobby like knitting or maybe crochet. Either of these two hobbies are a lot less painful when you crash........

Hey AL,
first you have to figure out which is the best engine to run the best fuel.....OS vs YS!
maybe TMoore knows..

Hi Cobraman et al,

The placement of the flybar in and of itself has no noticeable effect (at least for most of us). However, there is an effect that is an indirect result of the flybar placement.

A low-slung flybar GENERALLY forces the disk to be located higher above the CG of the helicopter. This means a longer 'pendulum' moment (the distance from the center of the rotorhub to the CG) and thus a slightly higher upright stability factor and a slightly slower roll rate (given similar models, blades, and pitch settings.)

For example, your Xcell, which has a low slung flybar and a pendulum moment of around 25 cm, will probably roll at best rate at around 2.5-3 sec per roll. Your son's Raptor, which has the high flybar and a pendulum moment of around 15 cm will roll at best rate about 1.5-2 sec. per roll. Granted, this is not an exact comparison because the Xcell is a larger heli with a different disc size, weight, and pitch setting. But given a similar model such as an EVO 30, you'd get similar results.

This doesn't mean one is better than the other. There are inherent strengths and weaknesses of both. So, I guess the answer to your original question is an unmitigated "maybe"...

thanks for response

hey thanks guys,,,,so much to understand. Im learning a little it seems like each week. I was just wondering about this. I have the x cell that i do hovering with and all, no training gear for a while now. Well got my son this raptor 30 v2 for his birthday so i figure we will learn together and hopefully not crash. I t will be definately not as expensive to repair the raptor as the x cell. Well any way thanks again guys...bye
