Dynam Speed Control

Product Description
Dynam Speed controllers for brushless motors are designed for best results with any type of motors and accumulators.

It can be programmed with JETI ESC programming card - available here.
- suitable for all types of accus NiCd, NiMh, Li-polymer, Li-Ion.
- programmable high frequency brake with non linear course and limited braking action
- auto calibrating with variable end point
- Low Voltage Cut off - slow down system with safety rest of accu capacity
-Modelers will enjoy extremely low (.013ohms) resistance combined with high rate(8kHz) switching.
-BEC provides power to the receiver and servos, eliminating the need for a separate receiver battery.

MMM 22/32 Speed Control

Click for larger view

I have replaced all of my Phoenix speed controls in my planes, Zoom Heli, T-Rex with this control and it works very well. If you run 4S or higher (battery voltage > 13 volts) - then you should also get one of our BEC's.

I setup a new experimental motor in my Formosa and ran it crazy with infinite verticle, 90mph speed and lots of verticle. I was pulling close to 40 amps but thought, let's test out the 32 and see if it survives. After about a month of flying I finally crashed and had to remove the wing to repair it. I was shocked that I found a MM 22 instead of the expected 32. I don't claim the 32 to have a proportional capacity, but the 22 certainly surprised me.

The only issue I have with the 32 is the Heat sink is on the shrink wrap - which I feel has a minimal cooling effect. I recommend cutting off the heat shrink and applying the provided thermal tape and heat sink to the metal an putting shrink wrap over the heat sink and then cutting a window through the shrink wrap to enable the cooling to be maximized.

• Motor Max Electronic Speed Controller for R/C brushless motors
• Designed specifically for plug and play and very user friendly.
• Supports 6-pole (70,000 RPM) and 12-pole (35,000 RPM) brushless motors.
• Dip switch to turn on and off brake.
• Supports Li-ion, Li-polymer 2-3 cell. 4 Cell supported but not recommended since the BEC can not be disabled.
• Automatic cell count detection for auto-shutdown 2S, 3S.
• Low battery function gradually decreases motor voltage to allow safe landing.
• Gradually decreases motor voltage if no signal detected at receiver.
• Beeper component used for status indications. No transmitter beep, and non zero throttle beep. Connect your power with thottle above zero and you are protected.
• Maximum load: 25 amps for 60 seconds, 22 amps continuous.
• Includes instruction sheet.
• Works on all of our motors.
• When stick is not in off position a repeating short Beep Beep Beep warning will be heard. By moving the stick to the off position the beeping stops
• Working temperature: 0 to 45 C
• One year manufacturers gaurantee, limited to replacement of any defective parts. This does not include damage caused by a crash, over-loading or improper use. Return of defective ESC's are required.

To set the Brake ON/OFF Toggle - Simple - Power off - FULL Throttle - Power on - LOW Throttle - Power Off:

1. Do not connect the battery to ESC.
2. Set the throttle stick to the HIGH position (full throttle).
   Connect the battery and you will hear four beep sounds.
3. Move the throttle stick to the lowest setting - you will hear three beeps.
4. Disconnect the battery.
5. Connect the battery again to complete the brake setting.
6. Do this again to toggle the brake off.

MDrive-60 Manual

Quick Guide Manual

MAKE SURE TO SETUP ONE OF YOUR USER MODES to "Motor Advance Timing - 15 Degrees" for any of the outrunners upto size 500.

Description: MDrive-60A controller along with MDrive-90A and MDrive-120A features the advanced Polar Pak MOSFET chips that have excellent thermal characteristics and the extreme low on resistance at high temperature range. The controller power board is constructed by four ounces multi layer printed circuit board with double sided of heat sinks. The brick type of structure design makes the operation more reliable and more compact in size.

The components of the controller are made of world famous semiconductor companies like Vishay that have the reputation of consistent reliability.

The ESC-View for Windows application software and the ESC-link serial programming cable makes setting up the controller is a snap. The software enables you to run the motor while it is connected to the PC and try out different timing and PWM settings on-the-fly. The software displays a dashboard with voltage and motor RPM displays so you can instantly see the results of different prop, gearbox, or controller settings.
