where is the problem

[heliry2]

last night i put on a new spindle and tail shaft along with getting new blades
balanced.turned everything on all looks good.this morning at my desk
i go to double check push up on throttle all looks good good movement
with servos good head speed.then rotors start loosing power.shut
down go to throttle up nothing.check battery 8.5V plug battery
into ESC 8.4V through both. plug ESC into receiver and motor
good movent all around with servos no head speed pitch servo fighting movement. throttle down
turn everything off. turn back on nothing anywhere no movement period.
has been running great new hitech 65 hitech 56 on rudder. hacker motor
hacker ESC TP battery futaba 7C full charge. where is the power stopping
absolutely perfect weather today in michigan to fly hopefully back
up sunday i'm thinking new ESC or receiver any help??

What kind of heli is it?

[heliry2]

caliber 400 all test were done with 2 different batteries with
same results another picture perfect day may be stealing
my sons 30

Sounds like you're running a 2 cell lipo. A setup like that probably requires a 3 cell. Those voltages are way too low. I'm not completely familiar with that bird, though.

If it is a 3 cell 11.1V, it might be stuffed @ 8.5V, because a 11.1V Li-po shouldnt be discharged below 9V :confused:

[broke-again]

Suspect the esc or motor if all was ok beforehand........check all wiring to the esc and motor..if in doubt, swap it out! Its the only way to be 100% sure.

[heliry2]

both batteries used for test were 3 cell 2100.
blax your right the one is stuffed at 8.5 but
the other has full charge with same results.
put a new esc on and were good to go.thanks
all for help.saturday night while trying to find
anything on receivers or batteries in my rcheli
mags i came across an article about 3 cell
and not letting go below 9 i did not know that.
the esc was programmed to 8.5 so that took
care of the one battery because when i put it on
the charger it would error the second one was at 12
need less to say the new esc is programmed to 9
again thanks and hopefully my problem will help
someone else.

[heliry2]

not so fast after new esc the other day we had esc problems
called hacker they wanted me to send escs' and motor
to them. new esc litterily melted off 2 way tape on
2nd flight and was fire hot they think it may be a
short in the motor will let you know what they tell
me. i overnighted them to get there today so hopefully
it won't be more than 2 weeks.

[heliry2]

it is 12:30 thursday in detroit just got off
the phone with hacker brushless and was told
there was a problem with the motor probably
caused by the 1st esc. so they are replacing
both the motor and esc. should have them within
7 - 10 days no charge delay is because of motor
back orders. hobby shop is going to credit or
refund money for the second esc my choice. i feel
thats pretty good service.

hrliry2 I would suggest a higher cutoff voltage. Those packs are expensive and 9 volts is the low end voltage. Go to about a 9.5v or a little higher. One other way to go about it is run your heli for a set amount of time start at 5 min then see how much charge you put back into the pack. I don't know where you will end up on that heli, on my Trex I get about 8 min flight times and still have about 10 v left over. So in my case if my timer goes off and I'm out a little ways or the wind is making landing difficult I have a little time before I have to buy a new battery.

[heliry2]

thanks for the suggestion i am going to program power reduction
at 10 fwhen my stuff gets back to me hopefully this week
the battery i thought was stuffed we got a full charge back into
with a tp charger but won't be able to see how it responds until
i am back up hopefully as good as new and give me one more pack

[heli-fan]

Good luck and let us know if that battery still works.

Hello Heliry2
When you have sorted your battery dilema's out, have a look at this gadget its cheap :) Especially were you live, I've got one on my T-Rex it has saved my chopper and my batteries as well :cool:
http://www.tech-mp.com/radio_elect.php
I've got a photo of my chopper with it on , when i can work out how to send photos I will :D
Hey I think I just worked it out, Yes there is the LGG just above the rear skid mount, nice and small and out of the way, the leds are extremely bright and can easly be seen..Neat hey?

[heliry2]

ups man showed up at 7:00 last night with my motor
and esc back from hacker put that and new airtronics
servo on. will get it tested tonight don't like the feeling
of the servo need to readjust the way it is mounted in
the tray.

[heliry2]

thank god we were in the air last night and all
looks good.had to have the guy at the hobby shop
teach me yesterday about setting up the digital servo i put
on the tail this week. heli-fan i will try that battery
tomorrow our forcast is rain and cold this weekend
so i will probably bring things to work sunday and
screw around here inside and see if i can go through a couple
charges.

[heliry2]

heli-fan that battery we got a full charge back into
i have twice run down to apprx. 10 and put a full
charge back into it seems to be o.k. i plan on
useing it again tonite
