Tiny Smartcontrol Mk2
Available now; the Mk2 has all the features of the original Tiny Smartcontrol plus the features of the Basic Smartcontrol. The Mk2 is fully compatible with the newer receivers such as the 2.4GHz Spektrum and has a user-replaceable input fuse to protect against polarity reversal on the battery terminals. See the SCT page for details.

The Servo Tester (SVT) is a diagnostic tool for testing servos used in radio control systems. It can also be used for testing electronic speed controls (ESCs). Featuring manual servo positioning plus an automatic sweep mode. See the Test Equipment page for details.
Price in US dollars is $84.99.
The SCO-30 is the newest addition to the Smartcontrol product family. An optically isolated control capable of running at a continuous 30 amp without overheating. It features automatic current limiting, automotive type input fuse, and flexible 15 gauge silicone wire (for motor and battery). It is compatible with 2.4 GHz Spektrum system. The ABS plastic case is included in the pricing. See the SCO page for details.
Price in US dollars is $119.99 plus $15 for shipping/handling.

Last summer (2006) a customer came in to the shop with one of these
systems. He was
trying to use an SCO-20 with the system and the SCO's LED was flashing red, indicating
that it was not getting a signal from the Spektrum AR6000 receiver.
I connected the oscilloscope and measured the pulse voltage output, it was only
2.5 volts on the high level. These new receivers must have a built-in regulator, probably
putting out 2.5 or 3 volts which would explain the lower voltages. Older receivers
typically run straight off the 4.8 volt batteries and they put out a pulse
voltage of 4 volts or more.
The SCO has a voltage divider on the pulse input to prevent a problem called latch-up
which occurs when the voltage on an input pin is higher that the power supply voltage
(which is 3.3 volts on the SCO). Making the SCO work with the AR6000 receiver is a
simple matter of changing the value of one resistor and adding a zener diode.
I will be modifying the input circuit on the SCO, SCB and ES4 to make them work with lower
input voltages, the modified controls will be available on Oct. 1, 2006. If you already have
one of these devices and you are switching over to one of these radios, you can return it
and have it modified for a $20 flat fee (which also covers the cost of shipping it back).
Please note: none of our older controls, which includes the SCA, the SCT and the original Smartcontrol will work with the AR6000 receiver.
