I wanted to know how does the different ESC combination would affect the quad flight or performance.
I got 3 little bee ESC 20a normal ones and 1 little bee pro ESC
Basically there isn't much of difference as much I know.
So will this combination in the quad would affect the flight ?

No one to explain. ..?? Sad

looking at the specs of both escs ...i don't find much difference between the two.
The only contrasting character of the pro over the basic is diff in size.
What i have heard is the pro handles higher kv motors better.
Both escs run on same firmware(version difference) and run same chipsets...so running that combination might not be a big issue.The flight of the quad in this case shouldn't be affected.
 I might be incorrect so let's wait for some experts's opinion .
cheers!

Thanks, I just want my quad to fly stable . Let's see some expert may guide us in better way.

unstability won't be an issue ,i think.....i have even gone crazier and used an esc of diff amperage and brand(different firmware) on a quad and still it flew rock solid...

Hoping for the best
