Tips for using the ESC
 If you store throttle corrections as described in step 1 at the bottom of page 2, then you don't have to repeat
the procedure before each flight. The ESC is ready to go (using stored EPAs) when you turn it on, and the mo-
tor will turn as soon as you move the throttle stick away from the off position.
If you fast-charge your battery pack, wait at least 5 minutes before using it to power the ESC. This assures the

ESC can properly determine the number of cells in the pack.
After you connect your charged battery pack to the ESC and turn power on, wait about 3 seconds before ad-

vancing the throttle. This gives the ESC time to accurately determine the number of cells in the battery pack.
If the motor cuts off in flight:

1. Move throttle stick to off.
2. Move throttle stick back up.
If the battery pack is in good condition, the ESC should provide 2 restarts.

Super 30 Auto Cell Detect
Electronic Speed Control
Model ASC30 for electric-powered aircraft using
Lithium Polymer, NiCd or NiMH battery packs
Features
 Works with NiCd, NiMH and Lithium Polymer (LiPo) packs.

User switchable brake.

Two user switchable Low Voltage Cutoff (LVC) options. Auto LVC, when enabled, automati-
cally cuts off motor at minimum voltage calculated from initial battery pack voltage. Custom
LVC, when enabled, automatically cuts off motor at a minimum voltage you set.

Throttle End Point Adjustment (EPA) for better tracking from throttle stick to motor speed.

Battery Eliminator Circuit (BEC) powers receiver from motor battery.
 Heavy-duty diode reduces electrical noise.
Note: When using LiPo batteries in fuel-powered models, use an FMA voltage regula-
tor/LED indicator, such as the Sport VRLI.
Cellpro Lithium Polymer packs are the next-generation replacement for NiCd, NiMH and Lith-
ium Ion packs. This unique power technology offers high energy density, low weight, long life,
safe operation and environmentally-friendly chemistry. Order Cellpro packs through the FMA
Direct Web site, www.fmadirect.com. LiPo technical and application information is available in
the Support section of the Web site.
Precautions
 Follow all instructions in this manual to assure safe operation.
 Observe frequency control. If someone else is operating a radio controlled model on the same
channel as your transmitter, do not turn on your transmitter—even for a short time. Your
transmitter has a channel number marked somewhere on its case. When a model receives sig-
nals from two transmitters on the same channel at the same time, it cannot be controlled and
will crash—possibly causing personal injury or property damage. For safety, most RC flying
fields have formal frequency control rules. Follow them carefully.
Do not operate your radio control transmitter within 3 miles of a flying field. Even at a dis-

tance, your transmitter can cause interference.
Make sure your LiPo packs are not fully discharged when you first connect them to the ESC

and apply power. The ESC sets its Auto Low Voltage Cutoff by measuring initial pack volt-
age. If the LiPo pack voltage is too low, the Auto Low Voltage Cutoff may be set too low, and
cells could be over-discharged. Charge state is less critical for NiCd/NiMH packs, but it's
always a good idea to start with a freshly charged pack.
 The Super 30 ESC works with packs of 5 to 12 NiCd/NiMH or 2 to 4 LiPo cells in series. If
Auto Low Voltage Cutoff is disabled, the ESC supports packs with 3 to 4 NiCd/NiMH cells in
series (however, your receiver/servos may stop operating at the lower voltage near the end of
a run). Never disable the Low Voltage Cutoff when using the ESC with LiPo packs.
