That exactly it. Just refining the current setup. In theory it should be more reliable and preserve 'new' motor performance for longer.

I have taken the decision not to make the bar more powerful this year as it'll near enough guarantee that the machine will launch itself out of the arena during the champs.

If I wanted to up the power of the bar, this could easily be done by going 8 cell on the dewalt, or putting the brushless system back in and refining it.

Don't worry, the new machine, 'Shard' will be more powerful
