Ditto, same problem here
I had some other issues but had to completely reset and start over again and then now I am down to just this one.
I am having the same problem. " Failed to set flight modes"
I can replicate this. We'll fix it in the next 24 hours.
The altitude is off by a factor of 10 now ! 10 x too little in the feet mode.
i will revert back to .73 when i get home. and sort this out.
Also not 100% sure if this is MP .74 because I haven`t tested everything, but I would say so? also but compass was out 210 degress on flight data after updating
I waited to upgrade from 1.1.73 to 1.1.74,,, because I read some threads regarding this problem.
Since... I updated from 1.1.73 to 1.1.75 and this problem do not exist.
In my humble opinion, dealing with many, many, many version upgrade of APM in a short period of time is to always click "No'" to the update available box... if you have a stable environement working.
Don't get me wrong I do understand why there is so many new versions.... like new Radio Hardware available for telemetry, bug fix, etc... But keeping a stable environment is (i think) the key to advance successfully in this adventure
Like Chris said... 1.1.75 is available now.
my 2 cents advise.
