Hydradrives - why the sudden increase in interest

[Graeme]

I guess the question is in the title but I'd like to know the advantages from those who have tried them. I seem to remember them going out of fashion post Kinwald's Worlds 97 win as they never were fitted on the XXX series (although I understand you can). Now they seem to be cropping up all over the place. Is this a brushless thing, a mid motor thing or just a 90s throwback?

Cheers

Back when they came out you really had to fight to make the batteries last 5 minutes with them on because they increased rotating mass by so much.
With lipo and brushles we now have insane amounts of power, speed and duration, so that hydras have become viable to use again. They really do smooth out a cars throttle response and make bump handling so much better, especially on slippy surfaces. Schumacher used to make a visco-drive back in the day as well, which worked similarly.

they where awesome and yes we need them now for bumpy tracks as power and endurance not a problem so someone make some money

I found a mint one in my attic when searching through my old racing gear

I think someone just ran out of double slipper spurs, xD.
Dual pads slippers were faster on 4x2, maybe we should give a try to the Hydra on a 4WD. Anyway, i think i have one somewhere, but don´t know how to try it on a B4.
