Tank Expo 2006

by Vern Dernberger

The annual Tank Expo was launched with the traditional donut and juice brunch. It has been found over the years that such a nuitritious start to the day leads to an excellent event. A total of 14 people attended making it a fun and informative event.
The biggest announcement at the show was the introduction of the Anvilus Cheap Six Channel (C6C) controller, which provides 6 channels of servo control at a range of 50+ feet using a standard wireless or wired Playstation gamepad. The prototype shown here has already been field tested, with good results.

The final version of the C6C fits on a custom PC board that is 1.25" x 1.75", with all components easily soldered in place. The C6C can be powered from a 6v or 7.2v power supply which powers both the micro-processor through an on-board voltage regulator and the servos directly.
The C6C serves as an inexpensive replacement for a standard RC radio system when only short-range control is required. The next generation controller will make use of a pair of these compact 2.4Ghz radio transceivers to provide an operating range of 500+ feet. The next generation controller will have an on-board controller with servo, relay and PWM outputs and a remote control module (that can be worn on your belt) that interfaces with a wired or wireless gamepad.

Steve Tyng handles the wireless controller to see if it will suit his fast-paced, non-stop battling style. The weight savings alone could allow him to run that much faster alongside his Cromwell.
Following in their tradition of providing cheap (and I don't mean inexpensive) plastic systems for the tank combat world, Anvilus unveiled this Hetzer kit that they recently acquired. There were no buyers at the show!!

Tyng Tech unveiled a set of new Unite 350W geared motors that perform as well as the legendary EV Warriors according to initial tests by Joe Sommer. The motors have an integrated metal gear box that delivers approx 250 rpms @ 12v which means they can be used to drive tank tracks with no additional transmission. The motors can be operated anywhere between 12 and 24 volts with an appropriate controller. Tyng Tech is importing a shipment of these motors and will serve as a commercial distributor.
Rick Schultz demonstrated his brand new, fully operational Stug for the first time in public. Everyone agreed that it looks great and is well made. Rick started building it from scratch after the last 2005 fall battle and completed it in about 3 months.

The Tiger and Stug leave some nice tracks in the soft mud during the traditional field demonstrations. The Stug was recently completed and will be competing for the first time this spring. The Tiger was outfitted with new control systems this winter and was testing them for the first time.
After most attendees returned to the shop following the field demonstrations, we were alerted to a minor accident that occurred with the Cromwell. Apparently, during a demonstration of its climbing skills, the Cromwell rolled itself over completely on its back ... with tracks flailing in the air.

Video Clips:
Cromwell Road Rage
The Cromwell shows off its road speed on a smooth surface with the Tiger hull maintaining a firing posture for practice.

Cromwell Surrounded
The Germans demonstrate how they intend to surround the speedy Brit whenever possible, while Steve demonstrates his smooth and speedy rotate control.

High Speed Turns
Although we never battle on such smooth surfaces, the crowd loves to see the armored equivalent of the popular "drifting" sport.

Low Rider Brit
Holy jumping beans. The Cromwell's suspension and proportional speed control allows it to perform some crowd pleasing moves, even though they probably don't have much purpose on the battlefield.

Turn vs. Pivot
The Tiger and the Cromwell demonstrate two different ways to conduct a battle. Turning and pivoting are both valuable tactics when used properly.
