3GX update help

[mike71]

0k been out of helis for about to years getting back in I picked up a 700e DCF hv combo and a futaba 14SG. The kit came with 2.1 on the 3GX and for the life of me I can not figure out how to update to 4.0 any help would be great Thanks Mike and I flew the old align fbl and always had good luck

Need more info, mike.

What have you done so far? By that I mean steps eg on the Heli, bound to your Tx etc

[mike71]

Setup on the sbus I did all the steps per manual. The tail did not seem right but its been two years so I was not total confident. I did how ever hover it and the tail was not working right was I figured I would update from 2.1 to 4.0 and I can not get it to load. Followed everything to the book but my old radio was the 10c and the 14sg is a little different . And is it ok to run straight for the rx battery seeing the servos are all align hv

Got the 4.0 loaded and redid the setup I will give it a try again in the morning

Glad you got it sorted.
Yes, running a 2s LiPo for your electrics will be fine (so long as your Rx can handle it)

Just be sure to run 2 leads, from the 2s batt, into the 3gx. Those Hv servos can have quite a high amp draw. I use one of these but I'm sure you can get a Futaba equivalent or even just make one like I did also. I made a 3 lead harness so I could power my Telemetry aswell.

Btw, what was the tail issue?
