When I'm flying my 600e, the motor will stall, it gets hot and shuts down(I think), I can use full throttle to get the motor running again.
I usually land, but the other day tried to continue to fly. I flew another 30ft and the motor sounded like it went to max rpm's and then it gave 10 to 12 degrees neg. pitch and threw itself into the ground. The heli is totalled.
I've talked to the local hobby store and they aren't sure why this might be happening.

Any ideas of why this might be happening?

Thanks for any help

You could have motor grounding on motor case . More info ? What electronics ?

I stole it ,flew it and gave it back ;)

From your description, I don't think there is anyone who can tell you what is going on.

You have (had?) a 600e. What other equipment are you using? Radio, battery, regulator, servos, speed controller, flybarless controller...etc.?

Is this your first helicopter or not?

The usual suspects are wires that have rubbed aaginst a sharp edge or the motor case, shorting wires together, a power supply in the heli that just isn't up to snuff, poor wiring practices, and improper set up.

You live in West Des Moines, Iowa. I believe there are two to three decent clubs in the area, with quite a few active, experienced heli flyers. Seek local help at the flying field.

If you have it all back together, some good pictures of the installation could help.

If all else fails, Cedar Rapids isn't all that far away. Get me your stuff for a weekend, we'll sort it out.

If not enough power to electronics esc and RX will reset going to soft start on motor .

I stole it ,flew it and gave it back ;)

not exactly sure what could have gone wrong with your heli but you have to listen to these birds. at the sound of any thing unusual you need to land and investigate further.
i was flying inverted once, just hovering and i heard one tick sound. I landed immediately to find out a screw had backed out and hit the blade while in flight. could have been bad if i had ignored the sound. I have learned the hard way that helis usually give you a sign something is wrong. we just sometimes choose to ignore.
get someone to look your next bird over before you go up again.
good luck

Heli keeps crashing
Are you flying with a group of experienced heli pilots? I suspect not. Flying with other pilots gives you many eyes on your heli when something goes wrong, They see it first hand and will have already developed ideas long before you could type it out on your keyboard.
Flying with others is a confidence builder and you have the benifit of have someone there if you were hurt. Try it!

When you fly JUNK it's hard to tell when you've crashed!

belt or TT drive.

that sounds an awful lot like what happened when you get static buildup on a belt and it discharges across your electronics (reboots your RX in the air)

if this is the case, you need to ground your belt by giving continuity from the rear pulley, to the front pulley, and to the frame/motor mount so the entire airframe has the same electric ground.

i've also had a bad servo draw a big enough load (though i think you'd burn through a servo wire before you pulled >20 amps) to give a voltage drop that would reset the electronics, too.

too many possibilities. and, tough to sort out now that youre at a rekit.

if it ain't broke, break it.

Read the flight log from the ESC and see if it shows anything.

I know you have a separate Rx batt and such. But any info might show something.

http://www.spektrumrc.com/Products/...?ProdID=SPM9540
one of these will let you know of any signal issues.

Then maybe one of these that will monitor and record flight data ( record on my Iphone ) to see what happens like Rx voltage and such.

I'm running in govenor mode. I programmed the cc esc, now I'm trying to set the end points. It seems to find the high end OK, but it doesn't seem to find the low stick calibration?
Any ideas on what be going on here? I've watched several videos on te TX setup, not sure what I'm doing wrong? Here the steps I've tried.
Set the throttle curve to a straight 30%. Set the throttle stick to high, had the end points in the radio set at 60% both high and low.
Plugged in the batt. ran the high up to about 96% and it bepped, did 2 more clicks. Disconnected the batt. and moved the throttle to low stick. Set the end point to low and plugged in the batt. Tried to find low stick, but couldn't get a beep out the esc. Tried going all the way from 60 to 150%, no beep, tried going back down to 0, no beep.
I also tried a linerar curve from 0 to 100%, nothing.
Anyone have any ideas on why it won't find low stick?
Thanks for any help

hrm...doesn't sound like the instructions i've ever used. i recall setting a linear (0-100) throttle curve and adjusting the ATVs on both ends down to do it. i just went by the video castle has on their site.

beware! (i'm not joking) turn down your volume. they have beeps at the beginning of the videos that would make hellen keller wince.

the 2nd video down is the one you want:

OP, did you tighten the pinion too hard against the main gear? Did you oil all your bearings a little after a half dozen flights? Are you setting the throttle much too low in the tx? Is anything on the heli rubbing something it should not?
good luck, fly safe

Is it not arming? Does it arm when you hit throttle hold?

That won't work. No matter what you do with the throttle, it's going to output 30% throttle. You need a simple 0 - 50 - 100 straight line curve (as you get with a new, or reset channel). Set the low position with the throttle trim LOW and the throttle low.

For your Spektrum radio, the throttle channel should be NORMAL, not reversed.

THEN ---

Follow this simple procedure:

http://castlecreations.com/support/...d_endpoints.pdf

Make sure you have moved the motor and pinion AWAY from the main drive gear while performing the calibration procedure for safety.

You're not looking for beeps when you adjust the endpoints, you're looking for the RED LED to go ON at full throttle. No beeps, just a good solid ON RED light.

I didn't read this whole thread but did note that the AR6210 is in the equipment list. I haven't experienced it but have read others have had issues with that model RX and higher servo draws. Do you have a different RX to try?
