Mounting the Throttle-Tech Controller and LiPo Tap Boards
The next photo illustration, figure 7 shows a typical installation. The larger controller board must
be mounted in the model so that the label side is visible. There are two LED indicators on the
label side of the board that should not be obscured by Velcro straps, dark colored tape etc. Either
mount the controller using adhesive backed Velcro to the underside of the board, or use a clear
tape to affix it to a flat, smooth surface inside the model.
The smaller LiPo Tap board is mounted with the label side down. You may use a light Velcro
strap (just slightly snug), tape or adhesive backed Velcro for the LiPo Tap board. Be sure that it is
positioned so that you will have free movement of the ESC battery leads when they are plugged
into the LiPo supply battery leads.

Basic Throttle Configuration
RC Systems work with channel control pulse widths for servos and accessories ranging from no
less than 900
µ
s (microseconds) to no more than 2100
µ
s, also expressed as 0.9 ms (milliseconds)
to 2.1 ms. The exact limits vary slightly by brand or model of radio system above the minimum or
below the maximum pulse widths noted. However any throttle pulse values outside of these
absolute min/max values are treated as invalid by the Throttle-Tech system, i.e. they are not
processed or passed along to the ESC. Typical low/high values with the throttle set to +- 100%
travel will range from about 1150
µ
s at low throttle, trim centered to about 1900
µ
s at full throttle.
The useful throttle pulse width range for the ESC will vary by brand or model, requiring that the
throttle channel ATV be set properly to accommodate the ESC. This is still the case when using
the Throttle-Tech system.
