6s setup with a 1300 - 1700 kv Neu 1515 & MMM V3 for when you are living in the US. Medusa 36-70-1600 kv would also be a good motor to start with although medusa has passed away....
For europe I would suggest to buy a MGM compro 8s 140 A controller directly at MGM compro. http://mgm-compro.com/index.php?cat=...for-cars-boats. They have a quick service and 2 year 'idiot proof' warranty. Price difference is just a few euro with a MMM V3 over an official agent. A very nice option they have now is a complete waterproof ESC!!!!! No fans needed on these 'though' boys. I am very pleased with the service and feedback on questions etc of MGM compro. I myself use both 2 160A 6s and 1 140A 8s MGM compro controller.
Lehner 1950 or 2240 series would also give terrific motor and can be ordered directly at Lehner.. http://www.lehner-motoren.de/ms22.php.

I would advice to use a UBEC (castle creations) as a bec is like a little heat source in every controller. A good setup with a decent esc doesn't need a fan.... For that a 6s for a truggy gives a much more reliable, efficient and cooler setup than one on 4s. 4 s for a buggy I see as a minimum and for the fact that a truggy is heavier 5 s seems to be the minimum to choose for, so go for 6s.

I see no need for using a sensored system.. Buggies & Truggies are to be driven.. not to use as crawler... I've no 'cogging' issues with the lower kv / higher voltage setups.
Althoug big I noticed that the hobbywing 150 A controller (also at RC-monster available) does a very good job. A friend of me has 'fried' ad MMM v3 is waiting already more than 3 months (yes 3 months!!!!! wat about customer service of ?Castle Creations for european customers... because of that MGM compro is the controller manufacturer to buy in europe, service = 10 days max!!!) for the replacement and is meanwhile running a hobbywing EZrun 150A. It runs without any problem and seems even to run more smooth than the MMM he has (but is waiting for to return...).
