Hi; i've been running a spektrum sr3000 in my truggy and from time to time it just allows my car to lose all control. I do have the fail safe set but this is garbage when it cuts out on me. I'm running a 7.4v lipo 3000mah 30C as my power. My battery is always fully charged, hitec servos....Not sure what the deal is. At first i was thinking brownout but my battery is new and holds a charge well.
