hi tom
looks like ash has done his norm and not read your post!!
personally i rate nosram motors, i dont like the motors with fixed sensor wring, seen to many damaged, nosram you can just fit a new wire.
same for speedo, never had problem, but as your in norway id see whats available round you, a 6.5 or 5.5 would be suited to 4 wheel drive
as your in NORWAY (CAPS FOR ASH!!) brca rules do not effect you, an i believe you can run lipo, Trakpower are one on the market leaders and have a full range of car specific packs.
as for charger look at the bc6 from bantam
http://www.flighttech.co.uk/Products...Bantam/bc6.asp does all you need and will need.
futaba are still up there and the 9551 servo is small and light.
