Am looking for any suggestions/recommendations on the 3GX itself.
I'm flying my first 3GX 5.0 firmware on a CHEAP HK450 with $12 FBL conversion kit.
3S 2200 separate 2S 7.4V battery and BEC for RX and FBL+ servos.
50AMP ESC HK helidrive 3600K/V and 12 tooth pinion.
All digital MG servos (OMG) 450 size.
Spektrum conventional 6 channel RX and DX9 TX.
Just to get started I studied and followed the RCHelp videos carefully and was very confident in setting up my first 3GX Thank You for the videos.
Maiden flight was certainly not anything like my BeastX out-of-the-the-box experience.
First problem was it did not want to keep the swash level taking off from grass.. the swash was pulling all the way over to the left and I could not center it.
Put in on the pavement and was able to manage it just fine and take off.
I later resolved this issue by getting rid of some of the negative pitch in normal mode.. it didn't seem to agree with that at all as it was probably pushing itself into the grass on spoolup.
I'm full throttle at 50% stick just before lifting off with positive pitch.
I usually fly with full negative pitch available even in normal mode
for more control.. I also usually use about 65% max throttle in "normal" flight mode along with same full pitch range as stunt modes.
It was certainly flyable but felt very "pitchy".
reminded me of flying flybarless WITHOUT a gyro of any kind only a tail gyro. I've done this many times for testing.
Here comes my first question:
In the software looking for cyclic gain settings I found that the elev. and ail have two different names...
I have:
Aileron Sensitivity
and Elevator Gain.
But not individual gain for ail and elev.
Is this just a typo? when they should both be called "gain"
ALso they do not seem to be settable in software but seem to be controlled by pots..
I started out with BOTH set at 117 which I thought was "high"..
after a couple test flights (extremely pitchy) it over pitches...
on ail or elev.
I ended up turning the pots "way up". I've not check in the software to see what the numbers are yet..
EDIT>
Just checked:
Ail sensitivity: 137
ELE. Gain: 196 (yikes all the way up!)
Correction "feels" about the same when you move the heli by hand sitting idle.
And not as 'strong' or gressive as the corrections on a BeastX same heli/servos.
And I also set flight mode parameter 1 (elev and ail) to "2 lights" instead of 4 lights.
This seemed to help it a LOT..
Was very flyable did some 3D plenty of inverted and simple piro stuff.
Piro comp was good and tail is rock solid.
No tail complaints at all, I can speed it up a bit later a little slow for my taste but it's at default. tail gain is set at 75 out of 100 (on my tx) in head lock mode.
That worked out of the box.
Flying good but still a bit "pitchy".
So really just curious what your experiences may be and what you have done to get what you want.
Bummer I crashed it on my 6th or 7th flight..
Took it up to 300ft and hit throttle hold..
was setup doing a perfect auto and just before I went to flare it
it pitched down just a bit and slammed into the ground really hard..
Seemingly on it's own I have no idea why and it seemed fully incontrol for the previous flights until this.
Not sure if it's just because of the pitchyness or if there was a failure.
It was a HARD slam... Only damage, bent feathering shaft and a bent tail boom and a bent pitch link.
SO to sum up my questions:
1. like to hear your experiences especially around "too much pitchiness" a little floppy on starts & stops.
2. Cyclic gains elev and ail..
where do you have them set on a 450? and can you only set them
with the pots on top the unit? or is there a way to do it in software?
I was only able to see it change in software by turning the pots.
b. One is called gain and the other is called sensitivity...
don't have gain or sensitivity for both axis
