Vertical speed sucks now

Pumpfixer · Jan 29, 2016

what the heck happened to my vs? Used to lift off like a bat out of hell now it cranks for like 3 seconds then ramps down to around 6mph
Thanks

The latest firmware reduced vertical speed to prevent cracking in the cold.

Pumpfixer · Jan 29, 2016

No kiddin. Where does it say that?

lookin4pain · Jan 29, 2016

is the speed also reduced in warmer weather? or was it just a quick fix for everyone across the board

No it wasn't!
It was to prevent sudden voltage drop on batteries which causes a big crash - then you DO get lots of cracks!!!

That 1.6 firmware sure is wonderful...

Wibble · Jan 29, 2016

Still running 1.19 - never any probs!

John Locke · Jan 29, 2016

I have found the VS is reduced at around 3.6V, or at 30%. Are others seeing any worse consequences from 1.6? I see my VS go from 11mph to about 6-7mph toward the end of the charge, around 30%.

No problems with 1.1.9??
Apart from not having the new features that came in 1ith 1.4.0 and all the bug fixes introduced over that time, have a look at your horizon sometime.
There's nothing magic about 1.1.9.

I agree it has reduced capabilities and yes the horizon is a bit sideways but better the devil you know!

Meh, reduced vertical speed doesn't bother me as i prefer gentle flying for smoother video

It's not better than 1.2.6 etc, etc up to 1.4.0 (and probably beyond).
There's no excuse to continue with old buggy firmware when thousands of users have proven newer is better.

You racing or photographing? Why do you need your quadcopter to do a bat out of hell? There are other drones out there for racing.

Any idea what is the oldest version I can run with Litchi really want to try it out?

Thats what mine was doing with almost full charge

Totally right you are.... I even have a racing drone..... I just really love the sound it makes when you goose it and accelerate away haha

Are there programmers on here who mod the firmware to allow faster horizontal and vertical speeds? I imagine altitude has been modded too right?

I think they are all in here.

From DJI's release notes:

What’s New：
1. In cold environments, propulsion output is automatically adjusted based on batterytemperature and cell voltage. Horizontal and vertical speed is also decreased to avoid triggering battery protection.
2. Optimized battery management.

No FW mods yet. we think we found way to bypass NFZ thing & that's all for now. i can't remember we got anywhere near customising firmware.
