what do you plan on doing. Racing or bashing etc. You can always with a little faster motor like a 19 turn with a 3300 or 3700 battery pack. You ESC has a 12 turn limit. Hope that helps.

18-19 turn is nice, then work with the gearing from that point. Too fast and you start to break stuff,when you loose control. The battery should be fine as long as the charger you have can handle it.

i say pick up 2 packs like 2400 or higher and a decent charger and a 19 turn motor. that would make it a bit faster and have longer runtimes. i miss racing electric

2400

I'd go with a 19T; Reedy Quad Mag's are my favorite because of the broad torque band. Better batteries will make all the difference. If you can't afford 4200's, go to the 3300 or 3800's for lower internal resistence and way more punch.
Deans connectors will make a noticable power difference because they will pass more current than the Tamiya (white) ones your speedo came with which can only handle 15amps. On your BK2 a 23T pinion is the ideal place to start for gearing with a 19T motor on most tracks.

Definitely a 19t motor would be a good choice, then you can probably get a 3300mah stick pack for not too much money as well.

Radio Shack actually has some pretty good 3800's that I always tell the new guys to pick up they are like $30

some of them are an integral part of the endbell now.

Since you are not really familiar with Electric, I would go with a motor that also gives long time between rebuilds, and that would be the checkpoint 19T. The Reedy is a great motor, but to keep it working as good as it should, you need more maintainance. You can really beat up the comm on them if you are just running and running.

As for batteries, Radioshack sells some pretty good sticks there, I personally for ease of use just get some GP3300s since they can be had cheap and seem not to need as much battery voodoo as the IBs.

Some speed controls (like LRP quantum series) require or strongly suggest using a Schottky diode on your motors. It protects the speedo from power spikes and also improves braking. Make sure that what you're removing is actually not the diode.

on the newer motors they come w/ a circuit board on the endbell which eliminate the capacitors that you need to solder on

Hyper, start with the battery,I'm in the process of training my grandsons and bringing them along a little slower and they won't get discouraged as fast with a car they don't handle well. There are a number of 3000mv nimhs out there for $30 and less. You'll give him a little more punch and longer run times. Then I would look to faster motors after he's got control with longer runs and more punch. Just my .02 worth. Be blessed,Rick
