This low cost CAPTAIN series is sold on a "Buy it back" assurance program.  It's a can't lose deal!  Details below.

This series of Reversing Electronic Throttles totally replace the mechanical throttle servos, cumbersome rheostats and switches that were formerly required to control DC Permanent Magnet motors in Radio/Control model boats, subs.  The RET series has found use in ancilliary robot functions and G-scale trains. All of these units are fully proportional in reverse as well as forward from one R/C channel. For the Plate mount version they are a compact 1.8 X 1.97 X .82" and weigh about 2.5 ounces.

The CAPTAIN RET411P, pictured above, is a ideal replacement for hot mechanical Dumas controllers and inferior units with sticky relays. With both proportional reverse and proportional forward it is perfect for R/C scale boats, small subs, tanks and auxiliary robots functions. It controls Dumas, Mabuchi 540, Astroflight 02 through 10 motors, gear reduced Astro 15 or 25 on 12VDC and most other motors rated 4.8 to 26 Volt DC at 12 genuine American Amperes continuous duty or 30 Amperes starting surge. See the sidebar on Ampere ratings at ameramps.htm. The RET411P features the tried and true circuit design of our venerable RET44 but with an increased voltage rating and MOSFET ratings totaling 155 amps. An optional heatsink version is now available, specify the RET411H.

The type RET512P is like a Novak controller that is rated to 26 volts and gives proportional reverse as well as proportional forward. Great for cars and trucks, and for smaller performance boats or larger scale hulls. The RET512P handles most '05 Hot Winds, Mabuchi 540, Astroflight ferrite motors operated at 14 cells or less, and most other motors operated at 18 Amperes continuous duty or 50 Amperes starting surge. Over 310 amps worth of MOSFETransistors. To order the heatsink version, pictured above, ask for the RET512H. Subs run nicely with the RET512 controllers.

The CAPTAIN type RET713P employs the highest rated MOSFETs available today to pack a reversing 33 amp continuous duty 85 amp starting surge controller in a miniscule box. MOSFET ratings total 480 amps. For your bigger toys like off-road trucks and dragsters and up to 26 VDC! It will handle up to Astro40 marine cobalt. Like the others this unit can be ordered as the RET713H with a heatsink. Or as the RET713P plate mount to bolt on your machines metal heat dissipating frame to save space and expense.
