here i used nothing as i clearly know, that we do not need any extreme stuffs for an RC vehicle.. the final drive train is a mere toy gear box, one withholds a reworked motor.. and theres no differentials.. and suspensions.. but she will run like a rocket.. in any terrain.. so, dont be stay away from making one.. need only some plastic gear box, two servos, and some scraped toy wheels.. result.. amazing RCying experience for hours.. here the motor was reworked for 6 volts and for torque.. so i reworked it with 35 SWG in to 4 strands.. so, at 7 volts the nature of the motor changes to a roaring lion.. and the traction control allows me to drive this lovely craft even on marbles.. all electronics are hand made except the RX.. i used a HK 4 here and converted in to 5, to shift the traction control.. total battery assy is 7.4 LiPoly in to 2200 mA/H.. with about the time of 40 minutes.. at high drift speeds..
so, i started from toy gear box, and a toy steering mechanism..
