[NSRCA-discussion] Another HV-85 question

[Ed White]

BTW, I'm new to electric pattern so sorry if this has been discussed and I missed it.

I've had one, and only one, flight out of at least 40 where I landed and the HV-85 was beeping an over current alarm (3 beeps).  Only happened once and my data logger said it was a normal flight, max of 64 amps (but my data logger is filtered and averaged so it would miss a spike).  Same batteries, same prop, same everything.  The maH used and put back in on the next charge were completely normal.  I had the current limiting set to insensitive.  I emailed Castle and got this response:


Turn your current limiting to
disabled, as you should in F3A planes.

Are other people disabling their current limits?  I've only had the one flight where the HV-85 said there was an over current and I couldn't hear or tell anything in the flight that was any different from any other flight.  I did disable the over current but am having second thoughts.  I couldn't tell that it ever had any effect, even on that one flight.  If it doesn't have any effect, it sounds like a little extra protection.  I'm tempted to go back to insensitive.

Subject: [NSRCA-discussion] HV-85 PWM Outrunner Mode


I've been using the new version 2.12 firmware for few weeks.  Last night I discovered that under PWM there is a new setting called "Outrunner Mode".  I tried it today and really liked it.  The throttle response felt smoother.  The ESC was not warm after the flights and I think it cut my amps a little. 

Anybody else have any experience with this?

Running a Dualsky 12T and have both Zippy packs and TrueRC(one 10C and one 15C).  At first I thought the TrueRC had a little more top end power.  Now I can't tell a difference.  Perhap the Zippys seem to need more break-in.  I've got 11 or 12 flights each on two packs and they just seem to be getting better.  Internal resistance readings are running well below 5 mohms on all twenty cells, many cells below 4 mohms on any charge.  IR seems to vary depending on how much charge is put in them.  Have had a charge were all 10 cells were below 3 mohms.

Was going to post some data on Chris' website after I got a few more flights on them.
