[NSRCA-discussion] E-deadstick, trouble-shooting.

Thu Jun 9 06:24:18 AKDT 2011

That is what I am running also.  The current draw seems to be on the high side of what Hacker recommends, but I also have not heard of anyone burning up a motor, at least not yet.  I recently upgraded the ESC from a Castle ICE 75 to an Ice Lite 100. The 75 would go into current overload at full throttle on a fresh battery. 

During a masters practice round on Sunday these are the number from the ICE Lite 100

                   Current     Temperature   Watts
Average           37.1             147           696
Maximum       104.7             184         1935

I'm running the Hacker A50-12S (the 5S motor), and an APC 16x10e prop on the Osiris.

What motor/prop are you running on the Osiris?  Thanks.

FWIW - I have the CC Ice HV 80 in an Integral, and the data logger
typically shows the temp rising to around 140-150F (60-80 amp draw)
and hovering there for the entire flight.  Castle tech support says

that their controllers don't start throttling back the juice until the
internal temp reaches over 200F.

What I find interesting is that I have the same controller on my
Osiris (5S pack vs. 10S pack) pulling the same 80 amps, but the

controller temp only rises to
 about 90F on the Osiris.

I haven't downloaded the data from Andersonville, but I didn't see any
power loss all weekend.  I'm sure that if the system was going to
overtemp, it would have happened this last weekend.
