I have been flying the BeastX and Vbars for a little while and have enjoyed that locked in feeling esp in the wind so when I had a chance to get the CGY 750 being biased towards Futaba I jumped at it. I have it installed on my Nitro Fury 55 and I am unable to get that same feeling when flying. Am I missing something here? She feels more like a flybar heli except the roll rates are so fast, is that the feeling it should be? Is there a way to get it close to a BeastX/Vbar feeling.

I am no where near the level of master 3D pilot, I just like to do Sport flying but this machine is just dam fast when it comes to Aileron Rolls and such.

I hope someone can help me here as I do like what Futaba has packaged in this little unit.

750 is for people that dont like the locked in feel or flybarless in general.

Mine drifts all over the place and a stationary piro in the wind is damn near uncontrollable.

Sounds like both of you have it setup wrong.

I was flying in 20mph winds this weekend using the 750 on a Velocity 50. The unit fly very very nice and was very predictable. There was the expected off course movement during sustained piros but nothing that wasnt easily managed...

The flip and roll rates were consistant. The piro rate was consistant with a good linear response. Basically it flew vbar 5.1 like minus the piro comp.

I noticed no weird darting, the heli was locked in very nice. I prefer its more direct response vs the BeastX. Feels more like Im in control of the heli vs having a back seat driver. The V Bar 5.1 gives this same direct feel IMHO.

+1, exact same here but feels even more connected than vbar to me. Only lacking piro comp and even then it's not so bad, piros pretty flat for me but still lacking in this respect vs vbar. Certainly not over the place and very nice feel to it! And I'm no where near a flybar lover!

Guys:

Can you expand more about the pirouetting behaviour of the 750?

I'm the kind of pilot who likes to do many pirouetting maneuvers so piro consistency is important for me. I'm going flybarless in a T-rex 500.

How does this system compare to the Beast one?

Thanks in advance.

Guys,

Nobody answered my questions. I am not getting any drifting. All I am saying is the machine is incredibly agile...much more than when it was a flybar, is this the normal feeling for the 750 or do I have a setup issue? Is it possible to get it close to the same feeling as the Vbar/Beastx?

The higher you go in flight modes, the more 'locked in' you may feel. As the number rises, the AVCS rises with it. Try it in 4 and see how you like it.

there is a roll rate setting on page 101 of the manual

called ang.rate default is set to 100 %
also check sensor mode on aileron on page 102

On the ELE especially, run the gain as high as possible without induce a nod. The AIL gain right now is about where it ends up for many people.

If you like the feel of the expo and so forth in the lower flight modes, you can increase the AVCS damp (esp the ELE expert menu) to get more heading hold feel without making the model too aggressive.

Nice to see a fellow NJ guy. Here is what i have found with mine and even though i'm no expert pilot i did let a very very experienced fly my X5 750 and my X5 vbar. He flies a BeastX now. He felt the vbar to be too disconnected an perfered the 750 hands down, said the 750 had made certain 3D moves easier than he had ever done them.

Anyhow i've been flying mine for a few weeks now and i really love it but have heard of a few people having issues, one is like your describing. Now I set my cyclic rate to just over 8 degrees after reading some inital posts from guys saying they had most luck with it set under 10 degrees. I have an identical setup vbar 5.1 x5 where i know it is flying pretty dam spot on and perfect and my cyclic rates feel pretty much identical. I have my agility set between 75 and 80 on the vbar and have my flight mode set at 3 now on my x5 and aside from the disconnected feel on the vbar the helis fly very similar.

Anyhow my suggestion is to start with your cyclic rates at 8.5 for both and see if it improves what you are experiencing...also if you are in mode 2 with 10 degrees then i highly suggest maybe trying mode 3 with less cyclic and maybe more expo if you need. I use the Vbar as a benchmark for setup as they have the process pretty spot on to get a heli flying to its potential. I dont think i need anymore cyclic to get the X5 flying perfect. The other reason i'm suggesting lowering the value is that for some reason the only guys i've seen have issues with the 750 seem to have more extreme values set. I'm no expert but i've been told i'm pretty good at getting a heli flying well!

Thanks Dr.Ben

Dr.Ben

I raised my Ele Damp to 110%...much better! I did not have time to raise the Ail yet. What I did notice now though is I need less expo. The machine is starting to feel confident aspiring and enjoyable without me sweating every second.

Since I am no 3D pilot what adverse effects should I be seeing if my gains are to high and if the dampening is to high and will I see them in a hover?

Thanks again
Mark

Joe1,

I am going to reduce that Pitch because I know for a fact I don't need that but it's nice to know that range and roll rate is there on this Fury 55

If your ail gain is too high you will see the heli start to shake side to side. What i do is put it into a hover and quickly move the aileron and look to see if it shakes.

For Elev gain i start by setting it to a high point, then do some quick climbs and then do some quick sideways turns to the point that i'm moving sticks to their extents etc. I have found that if it doesnt quickly turn around smoothly or get shakes after the turn yet the heil doesn't shake when you roll with ail input only then the Elev gain is too high. I lower it till i see it flying smoothly through turns.

I found it useful to temporarily set ail and ele to separate slider switches so i can adjust it within 10 or 20 points so that i dont have to land etc to change the gain. Once set then i disable the sliders again!
