I don't see what all the fuss is about....
I'm very new to the sport so that's probably got a lot to do with it, but I've seen more about incorrectly charged NimH batteries than LiPos
Let people use whatever batteries they want as long as they make the weight surely ?
I've recently put a fair amount of cash into getting started, and chose a lipo battery.
I worked it out as:
3300/3700/4200 packs: £60 ish each (and you'd need 3 or so for a night's racing)
Lipo: £80 and you need one
Charger for nimh: £a lot (up to £200 for some)
Lipo charger starts from £15 ish
for me starting out, it's a no-brainer...
