TMM 4412-3 HELI

Outstanding features of TMM® controllers HELI:

• great operation with all types of motors - outrunners as well as classic motors (rotor inside)
• all parameters may be easily set (programmed):
  
  • easily using transmitter without time limitations
• indication of cells being almost empty in advance by external LED as well as beeper
• outstanding care and protection of Lipol/Lion cells (of extreme importance) as well as of NiCd/NiMH (the system eliminates the impact of inner resistance of cells and amplitude of current on the switching voltage)
• outstanding masking of interference and signal dropouts
• extremely fine throttle step (1024 values)
• features mode with constant revolutions (governor mode)
• very simple maximal revolutions settings
• autorotation mode
• simple setting of flight modes
• outstanding soft starts
• small dimensions and weight
• very powerful MEGA BEC for small controllers sup to 44A and 4 Lipol (12 Nixx) or
  extremely powerful switching S_BEC for controllers 60A, 80A, 120A, 160A and 224A / 2 - 6 Lipol (6-18 Nixx)
• safe controller switch on; prevents unexpected throttle start
• signalization by diode and acoustically
• extremely small inner resistance of controllers due to:
  
  • using the best switching FET transistors
  • multilayer PCBs with extremely thick copper layer are used
• using 8kHz switching frequency with low inner resistance ensures very small losses in the controller
• version with switch is available also (safe connection)
• construction enables use of external coolers for better heat dissipation for more powerful controllers
• all versions manufactured also in version with water and humidity protection
