I greet everyone,
I'm designing a mini bicopter (I'm going to use small motors to be clear type 8520 that I don't have yet)

rx futaba 3,35gr
tx futaba T7B 35mhz
servo IQ -060 1.10 gr
battery 3.7 volt 2.50gr

but which mini controller board complete with BEC for coreless motors?
Can you advise me in this challenge, the enemy is weight!

I did not find any light indoor bicopters flying well ...

it would be a good challenge, who helps me on the type of controller?

thank you
