Speed not constant

[james54]

After the last update to my phantom 4 the speed in p mode is not constant. With full throttle the speed will go from around 20mph to 4 mph. Any help would be loved.

Interesting! Have you tried it in Sport or Atti modes?

They do seem to work better.

It looks like to me when it is in p mode it becomes unstable at full throttle so it slows it down.

Disable the obstacle avoidance system and the problem is gone... because otherwise if you fly close to the ground or uphill the P4 will slow down...
