First Flight Sucess/Gain Question

[PlaneHazza]

Aww crap. So the changes you make to each expert setting (AVCS.dmp etc) are mode dependant? So if I've set them to 100% on ele and ail in normal mode, when I flick to idle 1, they will be a different value on the CGY750?

[micccain]

I may be wrong but I think what quantummodz is talking about is the gain setting that are adjustable in the transmitter per normal, idle 1, idle 2. I think all of your expert settings are set.

[PlaneHazza]

Oh I see. I haven't got mine set to the condition switch. I have AIL and ELE on one swithc. and RUD on another. Once I have the gains the way I want them, I will move them over to the cond switch and have the gain a few % lower on each condition so I have less gain with the higher head speed. I'm still tracking wobbles and vibes so I'm far from properly set up

[rightto360]

I was confused on that as well. When we say mode, do we mean in the Swash basic or idle up? Also, I am using a 9C with the CGY-750, so the only built in programming I know of is for the tail gyro. I use the endpoints to adjust my gains from the transmitter. Is there a way to adjust my gains based on my pitch curve( ie. normal, idle up1, throttle hold)?

planehazza - no that is not the case AVC DMP is a all setting if you set it to 99 it will be that in every mode

GAINS on the other hand can be different for the tail not aileron and ele well on my TX anyway 10CG as i have assigned the aileron and ele gain to a switch and the tail gain to the mode switch so it gives me 3 x tail gain options normal / mode1 & mode 2

ok pitch curve endpoints info i gave

leave PITCH end points on the TX at 100 both ways

set up mechanical head to manual spec link lengths and servos and 90.

then set using the swash to head links 0 pitch at mid stick in MODE2

with me so far i hope

then in the CGY alter the pitch limit in swash expert menu so the lowest figure matches your desired pitch say +12 for example.

this may for example give you +12 one way high pitch and - 13.4 the other way low pitch

use mode 2 for example in the TX and adjust the pitch high figure by lowering the 100 pitch to say 98 to give you -12 then in your pitch menu if its set to conditions normal / mode1/ mode2 / hold amend the 98 across all modes so for example if you adjusted the +12 pitch to 98 you would have to also adjust it in hold and norm and mode1

then check the cyclic pitches to make sure they are even

that's it sounds complicated and hard to explain but its not ( well above was defined to me by an expert and that's what i did and it flys perfect ) also adjust cyclic DR so that you can do a full pitch roll without the nitro engine bogging is another area

that's why i say its a mix of things in posts i given that make it go from good to wow

not really GY750 related but heli setup related really


use one of them mode 2 for example

No that's easy enough. You're basically using the pitch curve to get equal collective without changing the end points that would mess with the CGY750.

Is it recommended to not go above 65% in the swash travel menu on the CGY750? I have the balls on the furthest out holes on my 90 and at 65% travel, my rolls and flips aren't fast enough, both stationary and travelling. So basically I'm now getting too much resolution and not enough throw.

[quantummodz]

exactly, leave limits alone and alter pitch with pitch curve and cyclic throw with DR.

i have mine on my 600n on the round align wheels second hole in and at about 30 on pitch and in the 40s on aileron elevator

my rolls and flips are fast enough for me

i set cyclic to 8 degrees and 12 pitch

on my settings you can see the rest of my setup in another posting here.

Awesome thanks mate. I'm such a geek, I can't wait to get home and do these settings all over again. No wonder my heli was a bag of hammers and full of interactions last time I was out! I've just remembered I did not do the pit-ail and SWcp mixes since updating to 1.2!

Another question from curiosity - why do you run sport on the tail rather than 3D? Just wondering what advantages you think it has?

The one thing that concerns me with regards to altering the throw using pitch curves and DR - will the offset curve not affect the linearity of the travel?

setting up the mixes as best you can does help with the feel a lot

sports mode gives you 450 piro rate which is enough for me i soften that further with DR to about 380 piro rate
3D gives you a 750 piro rate stupidly fast ( personally way to fat for me )

the in outs also change by a few clicks say sports gives you delay of 12 and the 3D delay of 15

i used the sports setup and added the 3D dlys but found i didnt notice a massive difference

pitch curve - try it and tell me if you notice that the curve is not flat when flying ???. ill be really impressed if you can. cos i cannot.

also at center pitch for a furtaba that's what i have a mode 2 pitch would be

100/50/25/0/25/50/100 using the method i relayed i have 88,50,20,0,-20,-50,-98

notice i that's lowered the pitch just of center stick also this gives cleaner transition feel as a little less pitch is applied as you enter exit a move

anyway it works for me so i thought as it was relayed to me by a 20yrs in the hobby veteran id relay to all.

Much appreciated mate, thanks. I'll have a tinker this evening and hopefully fly on Sunday.
