[NSRCA-discussion] Pletty CC HV 85 issue

[Dave]

Rex / Stuart,

 

Early on, there were quite a few setups that suffered throttle glitches
(intermittent brief power drops), but generally there was not a funny noise
associated with it.  Some of these were cured by various ferrite rings,
chokes, re-orienting RX and wiring, etc..but all of this was with 72 mhz
radio.  I've not seen this type of problem with the 2.4 ghz radios.

 

The problem Stuart is describing sounds different to me - because it has the
funny noise with it.  I'd be more suspect of bad connector, bad solder
joint, fracturing wire, etc.  If we were coming out of the spring into the
summer, I'd suspect increased power from the batteries might be the culprit.

 

Regards,

 

Dave

Are you running any sort of choke or ferrite ring on the receiver wire to
the esc?  Several of us had this problem early on...not just
with that combo.  This cured all the woes.  Mine would either start to shut
down or do a herky jerky hesitation thing...and start chirping
like you are talking about.  Like you, I'd throttle down a tad bit then back
up and all would be well.  After I installed the ferrite ring, no 
problems for the last 5 seasons.
Just so you know, I'm using the EVO and Schulze 32-80ka... before that it
was a 30-10 std and 32-55ka....and a 30-10 std with CC hv85.
All did the same thing.   All were cured the same way.  The only combo I had
no problems with was the 30-10 std with the Jeti 77 adv.

right away found no issues and flew the rest of the day without problems

with normal power and I was able to fly 5 more flights without incident.
