make its turbo be 200m/s

and maybe give it like 1000 more mass, i dunno

speed is fine, needs a second large weapon slot for a second mining beam.

...and it needs to be a Centaur...

In its current form the min.maud is a terrible miner, the average ice roid heats up to 50+K before the hold is full. :(
IMHO for it to be just right it would have to be:

Speed : 160 m/s
Agility : medium (err .. don't know the current numbers .. just a bit lower :P)
cargo : 70
hull : current or lower (8k?)
ports: 2l, 1s

That way it'd be hopefully to slow for trading or combat.
Atleast my mining grounds are usually only one jump away .. so speed is not much of an issue and 160m/s is enough to get out of most storm alive.

*nods to Mr_spucks suggestions*

and no infiniboost.

Yes to infiniboost. If you can't catch a ship who's top speed is 160mps (as per mr_spuck's suggestion) with the acceleration of a snail on a cold January morning, then you need to mothball your Orion Rev C and give up pie ratting forever.

The Mineral Maud is so-so for mining but great for trading heavy stuff. Which is another way to read its name, in fact.
I love it as it is.
Vive Tunguska!
