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. |

These units are optically isolated to eliminate noise "glitch" coupling and plug into your receiver like a servo but draw no receiver power. Available with connectors for Futaba "J" for FM or PCM, & Futaba "G" for older AM sets, Airtronics, Hitec, JR, Ace/Deans and Cannon/Deans. Compatible with many other radios as well. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Power MOSFET technology combines with
moderate rate Pulse Width Modulation so you get smooth low speed
operation, precise intermediate speeds and efficient full speed without the annoying
"singing" of model car controllers. The solid state H-bridge design uses no
relays, extra modules, nor are special heat sinks required. Unlike most hobby
controllers with exposed transistors that can short out, these VANTEC units are
fully enclosed and the critical MOSFETs that conduct your motor current are properly
thermally mounted to a metal heat conducting plate or heatsink with special insulating
washers. The case is electrically neutral.
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 table below on Ampere ratings. 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. For R/C combatants order the slightly larger and higher cost immersible RET411W (not illustrated). 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. The 32nd Parallel type 7 sub runs 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. |

| COOLING: Small models like scale boats will not require any special
attention for cooling. Closed hulls, like submarines, that contain other devices that run
warm such as batteries should purchase the next better rated model. Larger applications
with continuous motor loads at the controllers maximum ratings may require moderate
cooling air or "P" plate versions may require mounting by their aluminum
plate to additional heat dissipating surfaces. Because the case is electrically isolated
you can mount the plate to your metal shelf, tank mechanics or robot frame when required.
Measure your motor current under load with an inexpensive automobile amp meter.
EASY TO USE: These controllers come with complete instructions and the single centering adjustment comes factory preset for your radio but can be readjusted. No awkward rate adjustment required. There are two wires for the motor battery and two wires to the motor. Plug it into your radio and you are ready to go! ASSURANCE: The CAPTAIN series is sold with a 21 day examination period. If you are not satisfied we will buy it back! The RET has a limited one-year warranty based upon a nominal repair charge for units not tampered with or abused. Details available in Ordering. NOTES: A single Electronic Throttle may control several motors together if total current and voltage ratings are not exceeded; consider series as well as parallel motor connection. Dual motor systems with mechanically coupled shafts must be wired in series. The RET411 is not for model cars. Paralleling Electronic Throttle servo inputs or use with mixers for differential twin screw or tank type steering is not recommended; use our RDFR series speed controls made for that purpose.
