Drone requires 2 power on to start

Yep, it was definitely an issue with the Phantom 2 Vision+.

I can confirm my P2 V+ can and has taken off on it's own (only in GPS mode and only after having manually starting the props). Simply powering it on without starting the props was safe.

 

[Droning on and on...]

While it's a serious issue, it's also a bit funny to imagine you guys all serious and preparing and suddenly the bird gets a mind of its own and just takes off flying

Did it just ascend, or take off horizontally too? What did you do?

@scro the props on the mini 3 are pitched forward much more relative to the body compared to previous folding Mavic/Mini designs, giving it a nose-up orientation when hovering. More important, it results in the body being flatter in forward motion, cutting a smaller cross-section in direction of travel reducing drag.

A shift in thinking. It's obvious and natural to think of level orientation when hovering, but that's not the optimal design choice with a bit more pondering. Ideal would be VTOL Osprey-like motors and props the rotated on their arms.

The Mini 3 has this sort of haughty, jaunty stance to it when hovering. I like it

I was testing a dead P2 battery that I had disassembled and forced alive again by letting the props idle on my kitchen table. I was in the next room when I heard the prop speed increase and ran back to catch the aircraft inches from flying up into my ceiling fan. I was lucky to avoid impact but I learned to never trust an aircraft with props running and idling unattended.

@mightypilot2000 The DJI FPV introduced the idea of having the body level when the props are tilted forward & drone is in forward flight. After seeing that I started mulling ideas of rebuilding a mini 1 into a more aerodynamic, tilted body frame. It never got past the idea stage, and the lo and behold along comes the mini 3 with this idea in a folding drone body

That's right, it was the FPV first – good recall

Once exposed to the concept, it seems so stupidly obvious. It's one of those things that for simple reasons gets missed – of course you think of the drone level on the ground, then rising vertically in that same attitude on takeoff – and this bias is then reinforced over time with everyone designing them the same way.

Also, it's the natural design for a homebuilt before 3D printers, which is how quads came on the scene to begin with.

When are we going to get the Osprey tilt-rotors? Mavic 5?

Are you saying that from nothing being turned on to the moment your drone takes off should take 30-secnds?

Is this your belief or your experience? I cannot imagine that you have GPS Lock and Home Point Set... Amazing...

Pre-pandemic I was at a conference where an engineering group was demonstrating their prototype drone that used just that feature (tilting props) to keep the drone level. Less power usage when moving (smaller frontal cross-sectional area), the trade-off being more weight and more complication (for the additional motors and controls).

The DJI FPV and Mini 3 series do not have dynamic motorized tilting props like an Osprey VTOL... The props/drive motors are fixed like all other DJI drones. However, unlike earlier models the props are fixed tilted forward around 20° (that's a WAG, no one skewer me... @scro ), so after takeoff when hovering the props are basically level, while the body is pitched up.

30 seconds is most probably pushing it, but a Mini 3 class with the DJI RC will get you in the air pretty fast. Especially if you'd been flying just hours (or day or two?) earlier, and only need to get a GPS warm fix.

Just curious what was the fix? Also, which controller do you have?
