Wanted to know if i use this will i need a voltage regulator for my lipo since the switch has a lipo mode on it?

Yes the switch does not regulate voltage. Lipo mode is just to cut off power so you don't drain the Lipo past point of no return.

Thanks bud

Best switch on the planet...

Best switch on the planet = no switch at all.
Micro Deans, hardwire...done. It seems almost hilarious to see pros still have switch failures though. not saying the KO will, but why have something extra on there that might?? And if you still need to see a light to show you when to change your bats....

Ko gives a concerning notice while running it in LIpo mode

Not really true, it depends how it's routed/wired. I've seen both micro deans and a direct bullet have incidents where they come unplugged or unsoldered.

A microdeans flopping around outside the radio box it's no more secure than a switch.

Do the pro's not run these?

Too bad mine only lasted a few times out. Now it won't turn on.

Ko has the best warranty service ever unless its due to neglect

It's only been out twice both of which were with a brand new Protek 2s receiver battery.

I guess I'll contact A-Main.

+1, i wrecked a nova +4btt because a micro Dean that left without notice and lost a race and a nova P5 with a direct bulett that unplugged after a bad landing( runaway are now my nightmares ), since then I really can say that there is no rules on what is best, one of my friend even plugs the receiver battery direct into the receiver and goes the trouble of opening the radio box on a MBX 6 every time he comes in or starts drive.
I just ordered a KO propo switch and will give it a try, I now run KO propo servos and I have to say that last season went without any failures, that is something I never encountered with futaba or any other brands. They are expensive but really pays back.

I'd beg to differ. It's 90 days. I emailed them.

Hitec has warrantied stuff over a year old free of charge for me and some other racers I know.
