Ok, not exactly the same as the ones I used, but by the looks of it yours is non-adjustable with the timing? Probably just a change in paint from what I used...?
From this, I would suggest a gearing of between 55mm/rev and 60mm/rev, depending on track size.
By the way, what cells are you using? In my testing I started with "shorty" packs. These were extremely fast to recharge, even at 1c charge rate their capacity of 4200mAh meant that a charge rate of 4.2A recharged them in less that 15min (2s/21.5t takes very little capacity out of the cells). However, the shorty packs are slightly bigger than hard cased 1s packs, expensive and heavy. I ended up with the 1800mAh packs used in micro off-road buggies. These were cheaper, still recharged quite fast but I had to be a bit creative when fitting them to my chassis and getting it back up to 950g weight.
If you search for "How to power a Mardave" and read the thread on RCRaceChat, all my test data is there
