Hi,

I'm a bit confused with the assistance and maximum power limit of Mission Control.

It seems that the limits are electricals, and you have to take efficiency into account.

The big question is:

Is the efficiency the same when you limit at 10, 20, 30, or 60 %?!
Or like I think, the efficiency is lower at lower limits, which means that you limits far lower than you think when you set the limit to 10% or 20%!

If someone has done tests with a dyno, it could be interesting to have the results and have a curve of the efficiency vs power limit.

Have a Nice W-E.

Yes, thank you, I've read the thread several times.

Just have a look at the graph of a typical motor, below.

At low current, the efficiency drops quickly.

That means you can't thrust in the value below 20%, certainly not at or below 10 %.

Have a Nice Day.
