<DIV>Richard / Orland,</DIV>
<DIV> </DIV>
<DIV>I've posted a fair bit of stuff on RCU in various threads (I'd link them,
but I'm not the most organized with RCU stuff). The A60-20S is the
highest KV (245) of the A60-S series and cranks the highest RPM. My
objective was an electric that did not sacrifice airspeed, so I went with the
higher KV and smaller diameter higher pitch props.</DIV>
<DIV> </DIV>
<DIV>Hacker A60-20S</DIV>
<DIV>Castle Creations Phoenix 85HV (software version 1.53, high advance)</DIV>
<DIV>Thunder Power 10s4p 5300s</DIV>
<DIV>APC 18x10PN repitched to 12</DIV>
<DIV>~75 amps (lipos at 100F)</DIV>
<DIV>~7800 RPM (lipos at 100F)</DIV>
<DIV>Plane is a Prestige, with very good cooling ductwork, and hit the scales
at the NATs at 10 lbs even.</DIV>
<DIV> </DIV>
<DIV>Flying PO7 at 165-170 meters with large maneuvers is about 9 minutes
takeoff roll to touchdown. 3800 mah in calm/light winds, maybe as much
as 4300 in heavy wind. On 80F day, at the end of a flight, I typically
see ~90F on ESC, ~130F on motor, and around 120-125F on lipos.</DIV>
<DIV> </DIV>
<DIV>My oldest A60 has 214 flights to date. Oldest 5300 has 138 cycles
and might be down a couple percent compared to a 40 cycle 5300. Knock on
wood, no maintenance needed yet on any of the electric components, and no
servo wear yet either.</DIV>
<DIV> </DIV>
<DIV>My setup in the prelims at the NATs was similar - but less power -
APC 18x11 at about 7700 RPM, 68 amps, ~3500 mah for PO7, and lipos were about
110-115F (and ambient was 85-90F).</DIV>
<DIV> </DIV>
<DIV>The new TP Extremes will boost the power a bit more - I have a few
flights on the 3850s (same power as 5300s and 5.5 oz lighter) and the 4600s
(+10% amps and maybe +200 RPM). If you want a slower flight style, a
19x10E does that, but is a few amps more (maybe 80 amps).</DIV>
<DIV> </DIV>
<DIV>I have talked quite a bit with Sean Plummer at Hacker USA about using the
motor for pattern, and he is aware of the higher amps needed for pattern
compared to the spec for the motor. I'm not sure why the motor is spec'd
so low, but with proper cooling in a pattern plane, temps are not an issue at
75 amps. I have run the motor up to 95 amps and it didn't get much
warmer, but I was being fairly careful with the throttle.</DIV>
<DIV> </DIV>
<DIV>Hope this helps!</DIV>
