BigMike, Wtf did I just watch lol.
Hahahahaha
It sure is a lot of fun! No doubt. The low gearing is most impressive when you both climb and also drop off of something very steep.
When climbing, you can let the clutch all the way out and simply focus on tire-placement while you feel and sense the balance of the vehicle. You can feel each lug of your tires search for traction. Long past are the days of burning up clutches on the trail, bouncing all over the place and into rocks/trees.
For descending, you let the clutch all the way out and never touch your brakes. Just as you downshift into 3rd while heading down a steep highway grade, the engine compression braking effect is so drastically magnified with the Marlin Crawler, that given the correct setup even your full might of braking force with both feet on the pedal will not take any RPMs away from its closed throttle base idle. We can literally drop off of objects taller than your tire without inputting any brakes at all. The driver is in total control now. It's an entire different way to off-road.
We have these two reeaaaaaalllllllly old videos of the Crawler truck demonstrating this effect with a block of wood. Let me see if I can get them embedded here, hang on... hmmm can't get them to embed directly so I've uploaded them to my photobucket account. Hopefully they will load for you. Check out these classics, filmed with a toaster of course.
