Magnum Power Redux! We've received a new shipment of Magnum 775 motors with significant upgrades. We've added tie rods from the front plate of the gearbox all the way back to the rear of the motor can. This gives the Magnum775 serious strength to resist shock and lateral forces. Also the motor can be changed without removing the gearbox. Much easier to maintain in an industrial or Battlebot situation.

Sidewinder price increase We've increased the retail price of the Sidewinder by $20 to $399. Part of this is due to increased costs due to manufacturing them in the USA but we've also changed the enclosure to a nifty deep red metalic color. Also we'll be pre-soldering high-quality Silicone insulated power leads to the units so users won't have to worry about that chore and possibly damaging the circuit board or components. Just attach your connectors to the pigtails and go. We will post some new pictures soon.

The new Scorpion HX features the same physical size as the old Scorpion and Scorpion HP with the best of both units. The HX features the higher-capacity AUX chip of the HP along with screw terminals for all leads like the old Scorpion. Improved software helps reduce the effects of radio interference or weak signals.

Best of all the new Scorpion HX sells for the same price as the old Scorpion (not the HP). The Scorpion HX gives you the best small robot controller available for the best price. Available in singles and in discounted multi-paks.

IRF1404 option removed for assembled OSMC units
The assembled and tested OSMCs with 1404s have not been selling so we've removed that option and only the IRF1405 MOSFET will be available in assembled and tested OSMCs both single units and in combos. For the vast majority of users the 1405 MOSFET provides the best option. If you absolutely must have an assembled unit with 1404s.

July 31, 2002
New products added to Web Store
Robot Power is proud to annouce the addition of two new products to our lineup. The first and most important is a current-limiter add-on for the OSMC. This small unit prevents over heating and burnout of motors, batteries, and OSMCs by limiting the current that passes through the system. The user can set the current limit from 0-400A using only a voltmeter and screw driver.

The second product is actually a small family. The Magmotor combos are available with both the MOB and µMOB interfaces to provide extra power handling capability for large motors with four brushes such as the Magmotor or large Astroflight motors. The Magmotor combo has four OSMCs configured as two pairs slaved together with a daisy chain cable. This combo can also be used to control two smaller motors in a slaved pair. This is a cost effective solution for those running 4 motors in their robot with a slaved pair on each side.

Robot Power returns from BattleBots
Robot Power has returned from a wonderful week at BattleBots Season 5 competition at Treasure Island in California. It was a hectic week filled with customer support, a few on-site sales, networking with other suppliers and general "being there" for our customers. We also saw a lot of great robot combat.

April 20, 2002
