[NSRCA-discussion] More electric newbie questions

Dave....so you are saying:

No brake (regardless of idle or windmilling) - approx the same speed on 
downlines.
Too much brake - faster than idle/no brake?

Using Castle stuff….
 
1) and 2)     definitely not…..the idle RPM is not governed, and will wind up 
substantially in downlines, RPM will be the same at the end of the downline 
whether starting at low idle or high idle.  I’m not aware of any different 
behavior on other brands of ESCs.
3)  definitely not……wind up in downlines is virtually indistinguishable from 
using low idle.
 
Depending on just how many braking parameters you can adjust (which does vary 
between Castle, Jeti, Schulze, YGE), it is possible to have too much brake…..at 
a point, the downlines will become faster again when the prop disc is spinning 
too slowly.  I’ve been told that the ideal idle RPM (for maximum braking) can be 
calculated, but I don’t know anyone that has done this (and I certainly don’t 
have the knowledge to run the numbers).
 
Regards,
 
Dave

I can't find any definative reading on this so I have to ask the group.
 
Which configuration provides the most braking on downlines and approach for 
landing  (Jeti 90 + evo 30-10) :
 
1) Lowest possible idle
2) Windmilling prop
3) Jeti Med brake
4) Slighlty higher idle
 
My testing has not been conclusive....just not enough data.
 
Thanks
Colin.
