It's no secret that EVO can't climb in Ludacris mode, in fact, sometimes I have to slow just to maintain altitude. Do you guys think this can be corrected with software or are we stuck with it because of the aerodynamics?

DJI can hold altitude, Fimi Can hold altitude. Autel? Nope (it also happens in 34mph. In theory perhaps a firmware update could fix it if the underlying electronics can support all the extra power required to hold altitude (Battery, ESCs, Motors etc). My understanding is the Evo FC was derived from their previous XSP. Does this issue exist in the XSP also? Regardless it makes them looks like complete amateurs when it comes to flight characteristics as its an issue the competition eliminated long ago.
There are a lot of things I like about this drone but some are just plain odd and I have no hesitation to call them out on it (e.g. always having to disable OA, app wont retain custom settings, customisable buttons not customisable etc).

If their software will allow them to adjust the pitch while maintaining 45 mph -- then yeah -- software can fix it.
But there are other design characteristics about this machine where other parts of aerodynamics are at play.
The arms are fixed to the body at fixed angles -- with rotors attached to these arms at fixed angles.
You can't change hard plastic unless you melt it or crash it... lol
So you've got characteristics by design that can't change.
It would be different if say it were a model airplane and had movable flaps... here there is nothing like that.
So simply changing the pitch in software isn't as simple a fix as it may seem.
I fear that it is - what is it -- the fact it was poorly designed/equipped.
While some things can be fixed by software - I doubt this will be one of them.

I believe it can be done. You just have to tell the front motors to spin faster in intervals as to regain altitude, without affecting speed much.
That then strains the underlying power. Can the battery/ESCs handle the extra demand? They could also just have the FC pull back on the power so it maintains level flight automatically rather than attempting to pickup more speed by nosediving. I can gain more speed in a headwind on my Mavic by manually descending also.
Evo seems to do it automatically without giving the operator a choice, which is frustrating and could end badly.

The front ESC should be the same as the back ones, therefore be able ti handle the extra voltage. You also use max power when taking off. Also it has to be done in intervals or the drone will level itself and wont fly forward.
I really hope that there is a software fix. But I wonder if, unlike most drones, the fact that the rear props are lower than the front limits climbing ability at high speed

You also have to consider that the center of gravity is in the front of the aircraft. This is the main cause why the drone pitches so much, causing the aerodynamics of the drone to be pushed down by the wind.
Yeah, I didn't really think about that but the motors my be adjusting for center of gravity. Seems like a flaw that should have been obvious from the get go

I know the motors can give more power. Perhaps there is a patent that won't allow Autel to put the motors the same way DJI did. I'm just guessing at this point.

If the back motors are already going top speed, the only way to keep altitude from dropping is to make the front ones go faster, decreasing speed. It might just be a barometer issue but I think it is likely that Autel pushed the Evo beyond it's limit at 45 mph in order to beat the mavic. However, they can at least decrease forward speed and gain altitude when pushing up on the throttle with a firmware update.
I agree to that. Why not just reduce Ludicrous to 40mph and use extra power to keep control of altitude . Or reduce back motors rpm only at full forward pitch when throttle is increased to allow climb by some kind of inverted rear throttle response again only at full forward pitch. Seems that could be done with software and F. C. tweaks.
I always noticed both of my Mavic Pro 1's on same old firmware porpoise a little in sport mode at full forward pitch. It looks like the back end is bobbing up and down just a little and you can hear it with stock props or the platinum style quiet props. Never stopped to think its how altitude could be maintained on the Mav Pro although there's plenty of climbing power with Mavics sport mode at full forward pitch. too. Maybe Evo is too heavy and or the extra prop length has some affect. You can't see Mavics bobbing on the cam footage just L. O. S. although i bet the gimbal is getting its workout.
Because then it would stable and that would be Realistic speed Not Ludacris.

We don't need him to address what we're talking about here... Think about it, though it would be perfect, if Elon Musk did anything about the EVO, what that MSRP and cost to buy any hardware/software upgrades (and possibly even accessories) would be?!
Something we have to be think about, in terms of the reason as to why OEM drones are the way they are, we can guess there are redtapes all over the place and patent as someone mentioned. As what the FAA says that these drones can operate up to but not to exceed the ground speed of 100mph, I personally would like to see that the ludicrous mode be something I can set myself - up to 100mph ground speed!
As for maintaining the altitude issue, I would also like to think it'll be fixed in the nearby firmware update...
It's physics... The only way they can do it is to slow the speed, or speed up the motors... I would assume Ludacris mode is at the maximum-ish safe top RPM threshold for the motors. So any update will either cause premature motor wear, or loss of forward speed.

Here's a little update:
I just flew my drone in the Ludicrous mode with about 7mph headwind. It surprisingly didn't lose altitude while flying at 45mph!
Could it be the latest firmware update 1.3.46?
