I use a band and a spring. To me it's like your visa card "never leave home with
out it". Once during my nitro touring car dayz my power cable unravelled and
started dragging on the ground until it completely wore through the wire. That happened as I was going down the back straightaway at about 65 mph in second gear WOT. I lost steering,throttle and brakes luckily my throttle return spring kicked in and closed my throttle making an ugly situation not so
ugly.
