Hello,
Fiorotti active timer ( ref: CL_20Timer_20v_6_20EN.pdf) works well during static tests with two Spin44 Pro ESC, Himax 3516-1030 contra, and 4S battery.
I will fly my eParrot fitted with these tomorrow.

Please see my other message, titled "Shorter nose or longer tail or both when using the two-motors-in-tandem contra".
