New castle 6.5 connectors

[Heli biggie]

Well today the 800 lost power and I had to auto down, came in a bit hard and broke a landing skid. Could have been much worse, I was inverted.. When I went to unplug lipos one was already unplugged. These connectors were hard a hell to pull off so I'm not sure how it came unplugged during flight but now it feels not as tight as before . And these are new connectors. No other damage but sucks that I put better connectors on and this happened. Happy flying all!

Glad you got her down without too much damage Heli biggie. Well done

But, I wouldn't have thought connectors become loose by themselves in just one flight . ( It does happen, but unlikely, IMO.)
I would check there are no other underlying issues eg, signs of heat, batt short etc. Check your logs too, if you haven't already, before putting it down to bad luck alone.

The one esc plug in question was loose with all lipo connectors. So I was told that sometimes the inside with the slits sometimes get pushed together more, so I carefully stuck a small hex head driver in the middle and that did the trick , hard as hell to pull off now, just another thing to add to the list of things to check before flight, I will be doing a pull test EVERY flight now. Hopefully just a 40 dollar lesson well learned, I will also be wrapping them together with velco for double protection.

Ok guys I REALLY need help now. I had another power glitch after I swapped out to castle connectors. The 1st flight today went perfect, the 2nd flight had the power glitch .

Please help. I'm not sure what's going on except I must fix it.

align trex 800 power glitch 2 (2 min 9 sec)

post your esc settings. Especially motor timing.

[Heli biggie]

Gov mode set rpm
Gov gain low 15
Cutoffs auto lipo
Current limit norm
Current cutoff type soft cutoff
Auto lipo volts. 3.2
Motor start power medium 59
Motor timing normal 5
Pwm rate out runner

I have my Current limit set to (insensitive 280A)
PWM 12khz


Sounds as though it's going into Soft cut off

[nmdesertracer]

try putting your gov gain at 11-12. Sounds like it went into soft cutoff. PWM at 12 you have yours on outrunner.

[Bonkievan]

I have my Gov gain at 15 also.........

[atkin]

Yeah, try running not in outrunner, but 12pwm instead, and see if you can touch the motor for more than 5 seconds after a flight (how hot it gets)

Thanks so much guys , I thought I had everything default / correct. Have a wonderful day! More flight testing this weekend. But a little nervous.

Just take it easy for the first couple of flights after changing parameters. Maybe a bit ott but I'd check logs after 2-3 mins and at the end of the first flight just to ensure alls well.

Good luck

[Heli biggie]

Thanks so much guys, everything worked as it should today, no power glitches.i am so happy. I changed everything but the gov gain was left at 15! So nice to be able to trust the 800 again. So much to still learn. Got my half piro flips down on all helis also! Yehaw!

[Bonkievan]

That's great news

Doing demos for the school kids too, by the looks of the pic

[Heli biggie]

So the motor is still really hot after flight??? Can't touch for more than a second. But again today great flights with no glitches. Charging batts for more fun after this rain!

high motor temp is sometimes ok (high esc temp is not so good). Are your outside weather/air temps above ~75F?

My motor gets where I can touch it for 5 seconds, but no longer than 5sec, at 70F day temps. I think that's normal.

The only real test is with a temp gun.

Your ESC log above shows a max of 150F I think, so thats fine.

I live in ga so today I was sweating while just unloading helis, lol, I'll check my logs again when I get bored,thanks
I also noticed during pitch pumps that I had a bit of a front to back bobble , how to tweak that?

likely a setting in your gyro

[Heli biggie]

Pots gain setting or what, I noticed it more at lower head speed like 1700 but not 1800 but I like to run 1700 sometimes or lower. More info would be great help?! Other than that this heli is awesome!

If I had to guess I would say worn head dampers and/or CoG not perfect.
