hi all im new to the rc world and have got my self two new cars .the first one is a tamiys vr6 mk3 golf that i have wanted for 10 years ,the second is a hsp xstr brushed model .

my question is about the xstr ,how long should i charge the battery for and how long should i get out of it (running time )??

What charger are you using?
If you are using a charger that was supplied with the car then you will need to charge overnight every time you run down the battery.

yep its the one i got with the car .

how long should i be getting from a fully charged battery

well depends on the mAh the battery is rated, the chemistry of the battery, the ESC/motor, and where you are running it.

Problem is your Charger and Batteries.
-Capacity of you NiMH batt is lower than the power of motor.I dont know your motor power!.So 10 minutes running time is right.
-Your charger is the common charger.This chargher can not be adjust the circuit and voltage. I think the charger has output 0.5A~ 500mah.Give you the simple formula :   1800/500 =3.5hours.
 If you want to play with more running time you should change to lipo battery with 4000-5000 mah capacity.And you should have the special charger for this. Imax B6 ;Cellpro 4s ,Orion charger....
