this... and it is in permanent use to delivery "real" power for "real" power-demanding (bec) flying i've done than too once on a heli (was just easier for cabling) and had it in use for 2-3 yrs. "in case of" (power failure) there is no hard 3d flying anymore, just as-smooth-as-possible auto and landing - there will not be 20a bec peaks anymore. as power rail on the Rx is common i had no fear doing so and i have never seen a difference to other helis (stabilization/peaks/voltage dips) that had the buffer directly connected to fbl. not on bench testing, not in telemetry logs, not buffer charging when powering the heli.
