The built in fail safe on my Nomadio React saved the life of my Hyper ST today. I was on the street testing out a dynamite 053 pipe at full throttle and my receiver packs goes dead. My truck was going full wood into oncoming traffic. Luckily, the failsafe kicked in and the truck slowed down so the incoming car could avoid "killing" my Hyper. It was all my fault. I new my battery pack was really low, but I ran my truck anyway. Thank God for the Nomadio React. It is an awesome radio.
the spektrum has a built in fail safe aswell..but..i still use a throttle return spring just for safety
