3gx v4.0

[MartinW]

Is there any way to know if your built in BEC is sufficient other than just trying it and waiting for the brownout (which doesn't seem overly sensible to me) ???

Out of interest what tx are you using ?

[MartinW]

Who? me? DX8 if you did mean me, apologies if not

The 250 muct have the 'blue' esc for 3gx version 3 or more.

[MartinW]

Thats a shame. Oh well, v2.1 it is then

Using a dx8 here too. Just upgraded to version 4.0 but its still binding as DSM2. Checked tx settings but won't allow to bind DSMX even with 2 DSMX satellites.

Silly question do you have another dsmx rx that you can use your dsmx sats with?

From what I have read there is a special bind process for dsmx. Copied from a post on HF:
1.Select DSMX in the radio (DX8)
2.Install bind plug in 3GX
3.Press and hold Set Button on 3GX
4.Power up 3GX (Both Sats blink quickly)
5.Release Set Button
6.Bind to TX
7.Remove bind plug

Brilliant thank you, that works. Now bound DSMX. Do you know whether that is new to v 4.0 or has always been the method of binding DXMX?

It's new to v4. Dsmx sats would always bind as dsm2 before.

I'm on V3.1 & happy with current setup. What improvements would I find if went over to the new V4.0? (radio is Futaba S-bus)

From the Downloads page:

3GX V4.0 Improvements on Flight Modes:
Improved collective pitch to elevator compensation function to stabilize helicopter attitude during rapid up/down movement of collective pitch, and to maintain consistent stability during fast forward flights, rolls, and other maneuvers.
Reinforce stability during fast collective pitch movements. When fast collective pitch command is executed, the helicopter's attitude is stabilized.
Improved helicopter swashplate control smoothness, creating smoother control response and improved stability, resulting a dramatic overall control feel.
Improved tail holding performance; Better consistency in pirouetting speed and better locking effect.
Improved better compatibility for different helicopter sizes large to small; More consistent control feel from 250 size to 800 size helicopters.
Improved helicopter swashplate movement stabilization; A more solid, stable feel at the stopping point after concluding rolling or maneuver pauses.
Added support for Spektrum DSMX satellites.

* 3GX V4.0 Setup Reminder:
3GX will revert back to factory default settings after update; therefore the setup procedure must be performed again after the update. During the setup process, follow the standard sequence of swashplate settings, rudder settings, and then the 3GX throttle range calibrations must be performed as well.For safety reasons, before setup procedure please ascertain Motor and ESC didn't connect together, to avoid start up rotator endanger yourself and others, or result in damage to the product or the property or others.

- So i did the update today on my 450 Pro from V3.1 and all looking good on the bench, i did follow Align's advice fully and didn't come across any issues. I am using the stock Align ESC/BEC (RCE-BL35P not X) so was keen to bench test for any extra power draws from V4.0 and i didn't get any major drops in telemetry voltage or brownouts so appears to be similar to V3.1 for power draw and i'm running the BEC at 6V max.
I did have to redo the setup procedures as recommended by Align as it did revert to default settings but the 3GX settings file i had for V3.1 does seem to have been preserved which is nice.
The only difference i noticed was the Rudder Gain setting was lowered from my 30 setting in the software to 20! all other settings including rudder locking gain have been preserved. I am presuming this was intended by Align, but will only know if i need to raise the gain again after i test fly her, hopefully tomorrow.
Fingers crossed

Update:
Now test flown 450 Pro on 3GX V4.0 and initial impressions are excellent.
Heli feels very different in the air, more locked in and steady especially when using hard changes in collective, overall very happy with the upgrade.
Apart from the weird issue of the ESC/BEC resetting to default settings which I don't really understand and the strange changes in the gain values through the software, all seems fine.
I didn't have any power issues or notice any strange tilting behaviour, actually it felt better than any previous upgrade I've tried on 3GX so a definite improvement IMO.
I don't fly hard 3D yet but even with my basic skills it felt much better to me, so I think anyone with better skills than me and fly their Heli's a bit harder would notice a dramatic improvement to the firmware

Unlike when V3.0 was released, this version appears to have been tested better before release, so congratulations to Coolice and all the guys involved in the beta testing of this nice upgrade.

I've got same problem with my 450 esc/3gx resetting, but in flight no problem so on 6 flight i connected heli & sat it down esc done its bleeps & fine done same again on 7th all good then i reconnected the battery whilst holding heli & it done a reset after a few secons, I think what you have to do is once you've connected heli you must set it down to complete 3gx/esc to set.

Tested v4 on Vibe 50, 600/700 and 2 x 700DFCs, all nitro. Didn't bother with re-doing the setups, just upgraded over the top if 3.1 on all. It didn't revert to defaults.

All flew perfect, much more locked in, tail holds solid in high winds and finally the gov is back to as it was in v1.2. Also noticed power consumption on the tx batteries is down, 3.0/3.1 is very heavy on power.

Well done Align, another good release.
