7.5 motor would be the pick, I use a 6.5 light but turn the endpoint down on the tx to 95%. Its still too quick... Gearing around 19:84. Make sure the vent holes in the body are cut out to get some cooling in, and the standard Novak GTB fans are crap, get a Muchmore one.

I'll talk about the B44 as it is what I run;

1st thing, slipper clutch & diffs. If these are not right you'll be going through diffs petty fast. If setup right they last for ages.

I run the front diff tight (screw all the way in). This helps with getting power down out of the corners.
Rear diff as per the kit settings, maybe a touch tigher - it must not slip - ever!
Slipper clutch. This is the part that is to take the shock out of the drive train when landing of jumps etc. Easy way to set it up is hold the spur gear by your thumb and try to push the car over some carpet. It should be pretty hard to hold the spur, but the slipper should slip and not the diffs. Do this with only the rear wheels on the ground, same again the slipper should slip and not the diff. When set right the slipper should slip for about 1m when you nail the trottle on a grippy surface (not the lounge carpet...)

Setup - I run the B44 kit setup with the following changes;
silver rear sway bar - helps keep the front wheels on the ground when exiting corners.
25wt oil & #2 pistons in the rear - slightly lighter damping than the kit setup in the rear as the lipos are lighter than NiMH.

Well maintained shocks make a big difference in mod, if there is air at the top its time to rebuild them.

Tires holeshots or Jconcepts DD's. Both about the same performance but the DD's last longer. Ones I'm using have done over 15 meetings!
