A setup problem

[insane]

ok im having a little problem. Its been almost 2-3 years to get my NN chassis done. Now its time for the electronics. my first attempt seemed ok but i experienced a few annoying problems. my setup was a tekin rebel 2, 2 JR z650m servos, a spektrum 2.4 DX3 radio...the old one...with i think the 3000 reciever, a 7.2v 4200 mah battery and 2 integy 55t motors.
the problem is when i turn on the radio and esc, everything seems to work well...then when under load, the radio cuts out...seems to turn off and the esc i think shuts down...o sont know how to fix the problem and wondered if buying the nivak crawler esc would fix the problem or if its the radio and i should buy the tq3 radio setup... so i come here to the forums to ask a few things of all you. first i need help fixxing this. and secondly is if you can post a pic on ur setup. only catch about the pic is that it needs to consist of a brushed setup and either a tq3 or spectrum setup...either lipo or nimh... Thank you for the help in advanced...

you are probly just overloading the system. before you buy an esc try an externat bec. might help and they are only like $20.

it will give every thing enough power which i think is the problem
