BEC needed for futaba 604?
While running my 1/12 scale 13.5 with a Tekin 1s lipo and a 350mah rx I would flatten out about 2min into a run. My 1s would go down to about 3.94 volts from 4.17 and the rx pack would plummet to 6.70 from 8.4. My rollout seems to be in range (74.65) about 8deg timing in the motor 20 in the speedy. I'm wondering if the Futaba rx needs a BEC. Also, before the main I took it out and got a full run out of it at speed. Any help?
