[NSRCA-discussion] JR and un-regulated 6V

[John Ferrell]

Three-terminal regulators dissipate the unused part of the power.
My Prophecy takes about 135 mils per flight to recharge. There are a lot of factors that affect this number, especially airframe vibration.
I keep an eye on it and am more worried about it being consistent rather than some value.

  Does running a regulator, like a 5.1v-5.5v or 6.0v regulator, have any signifigant draw on the battery as it regulates the voltage?  I have been using the MPI Miracle switch that regulates to 6v.  I can get (4) 15 min flights on a 1650mil NiMh pack(Sanyo) before my ESC says to stop flying.
  I will put back about 700-750 mil on the recharge.

    Hi Matt,

    Are you using low-impedence nimh packs?   Would you divulge your battery source?

     

    Thanks, Chris

    I am doing that with NO problems. Fast charged on the way to field most of the time, with a Serius fast charger. In my set-up, a 1650ma NiMH lasts about 3 flights longer than a 4 cell pack of equivalent capacity. Equivalent ending cell voltages of 1.20v unloaded (1.15V loaded with 1000 ma draw) for either battery. 

     

    Getting greater torque and speed as well as longer flight time. Best all around
