Huina 573 / Top Race TR-212 Radio Control Dump Truck Modifications Part 2

Modifying Huina RC dump truck part 2 using WPL B-16, 1/16 scale 6 wheel drive (6x6) RC military truck undercarriage with high torque motor and 2 speed gearbox also used Fly Sky FS-i6S RC radio and 10 channel receiver, micro servo for steering, micro actuator servo to lift dump bed, micro servo to shift gear box, 30A Electronic Speed Controller (ESC) and electronic switch to turn lights on and off. Huina dump truck came with hard plastic tires/wheels and no suspension and would get stuck on almost any surface also the dump bed would not go up high enough to empty the box. With the use of the WPL 6x6 undercarriage, soft rubber tires, independent suspension, high torque motor with 2 speed gearbox this truck can handle most any terrain and any load. With the long stroke micro actuator servos long travel the dump bed will raise high enough to empty the box. The wheel base between the Huina dump truck and the WPL B-16 army truck were almost identical but there where a few differences between the frames / body's making for an interesting modification and machining an aluminum spacer plate to accommodate these differences and the strength to attach the micro actuator servo anchor for support to lift the dump bed. All and all this was a very fun modification and update build.
