Here is my new TBS source one! it is a build at the price content or I prefer the resistance.The electronics are entrusted to MATEk, a sure value. It runs under BETAFLIGHT 3.5 with rescue mode. I will later change the motors by brotherhobby + esc under BLHELI32 but current racerstar budget motors are already very good for catapulting the drone in the clouds ...;)
