    The problem with the gear change is the front is now doing all the work as long as all four wheels are on the ground. Also if you drive any distance (not strictly climbing) you will scrub the tires off and wear the drive train.

    • @TheShopMiniRC
      @TheShopMiniRC  10 месяцев назад +3

      Yes. This is for trucks that climb. You would never do this on a trail rig or go fast vehicle.

      Hmmm it appears that in one part of your video, "when you pull forward it sinks in" Im guessing this is a fully custom build. Do you have a video on the entire build so I can get a better understanding please. Again thanks for the info. Very informative and helpful to when I try to mod my scx24's.

    • @TheShopMiniRC
      @TheShopMiniRC  Год назад +1

      @@ralphhunterbayne65 it “sinks in” because of the over drive in the front or underdrive in the rear. The fact that the rear is slower than the front causes the entire truck to “suck down” when going forward. Just adding underdrive or over drive to your truck will make it do the same.

    I got some overdrive gears for my front and rear axles. something I noticed was before I changed the work gears I could turn the entire drive assembly by spinning the wheels but wit the new overdrive gears I cant do this. I can still rather easily spin the drive assembly by turning the drive shafts but not by turning the wheels. Do you think this is a problem or does it have something to do with the harder gearing or something like that?

    From the ground up. Without having anything to go by my first hiccup is, I want 4 wheel steering. I see that the transfer case spins the drive shafts the same direction meaning the gears have to be changed in the rear steer axle. Can that be done, or do I need a specific axle?
