| ATV | Adjustable Travel Volume. Basically another term for EPA, just sounds fancy so the vendors can charge more for their transmitters. |
| BEC | Battery Elimination Circuitry. The BEC is built into the ESC (Electronic Speed Control) and uses the main battery pack to provide power to the receiver. This system allows you to power the receiver without the need for an additional battery. The speed controller plugs into the throttle system on the receiver and therefore provides power to both. A good speed controller will monitor the voltage on the receiver and will remove power to the motor in order to protect the power to your receiver. The downside is that ESC's are electrically noisy, so in our high AMP electric boats the BEC can often cause glitching. With a BEC you can't be opto isolated to prevent the ESC noise from entering the receiver. |
| CA | Cyanoacrylates. Remember the commercials where the guy was gluing himself to a beam and then got hoisted into the air? Super bonding CA glue is used to hold hulls together among many other tasks. |
| D/R | Dual Rate. On most radios the dual rate cuts down the throw of the steering by an equal amount in both directions. When you are on the water you can dial out some steering if you find yourself with to much. |
| EPA | End Point Adjustment. This setting is one of the most valuable features of your radio. It allows you to set the servos throw in both directions independently. This way the servo is not hitting things that can limit its travel and overwork the servo. It also allows you to set the maximum amount of left / right steering. |
| ESC | Electronic Speed Control. Used to control the speed of the boat with FETS (filed effect transformers) This device takes inputs from the receiver and controls the speed of the motor by allowing current to flow from the battery to pulse through to the motor. |
| EXP | Exponential. This is an adjustment found on many, but not all, radios. Its hard to understand at first but it alters the ratio of movement in the input (radio) to the output (servo). An EXP of zero means if you move the steering wheel or throttle 50% the servo moves 50% of its travel. Altering the number in the negative direction alters the ratio, so if you more the throttle 50% it may only move the servo 25%. This helps on those days where you are over caffeinated. |
| Glitch | Glitch. When the radio transmitter signal is interrupted, either due to low batteries, loss of batteries or for any reason that the receiver is not receiving a steady signal, it is referred to as "glitching" or "interference". To make sure you do not glitch, be certain you have fresh batteries in your transmitter radio and in your receiver. |
| Opto | Optical Isolation: Indicates that the electrical current for the power system is isolated, which makes motor-induced radio interference less likely. The design of opto-coupling makes it impossible to incorporate with BEC. |
| POS | Piece of $#&*. Self explanatory. Often used to explain bad driving with the word You used in front of it. |
| RX | Receiver. The receiver is installed in the boat and takes the radios input and delivers it to the appropriate servos. |
| Tweak | Tweak: A condition where a small adjustment is needed to the rudder or strut to make the boat track better. |
| TX | Transmitter. Better known as a radio and sometime incorrectly refereed to as a remote. |
