        Help! Something Smoked. ESCs not arming.

Something Smoked. ESCs not arming.
 
This is VERY time sensitive and unfortunately I am on location in Baja covering the Baja 1000 for Monster Energy. We have had a great first 3 days of pre race flights and should have our first edit posted to Monster tomorrow. BUT!!!!!

I needed to spin up one motor at a time to check the motor balance and think I blew it when I meant to plug in an esc wire and actually plugged in a Rx wire to a second Rx to spin up the one motor. I had a 3s battery also plugged into the Rx.

To make a long story short, something smoked on the HFP board and now the ESCs won't arm. I do have a backup green board, but have the black board well tuned for this Octa.

See the photo below. The tip of the tool is over the smoked component. Anything I can do? Any way to bypass the smoked component. I am in Mexico, so no access to anything more than wire and a soldering iron. Race day tomorrow and will be out of touch for 2 days. :eek:

tahoe, with the new firmware the same settings should work exactly the same on the green board as the black board. The only thing is you would need to check the gimbal controls. Sorry to hear about this. I used to own a green board and did something similar but burnt out a circuit track and was lucky enough to be able to replace that with a fine wire. Good luck.

Yeah stacky, I am confident in the green board as a back-up but planned on having two helis ready to fly today and tomorrow. But, next flight is in 3 hours and I went ahead and mounted the green board on the Octa. I also took the time to balance the prop and motor combo together and got rid of any vibe I noticed in yesterday's shoot ( this time I plugged into the ESC instead of receiver wires :) ). Flight tests proved successful without changing any gain settings this morning. Flying like butter, but no backup for the next two days of shooting in harsh conditions. Keep an eye on the monster energy website tonight. First edit is being finished. Some fun shots of flying the heli just over the road. I have to lift off high before it gets engulfed in dust.

Sorry I didn't see this sooner, but that component is the logic level converter. Basically, you will have problems arming some or all of your ESCs until that part is replaced. Sorry man!

Thanks. I will send in a ticket to see if you can help when I get back.
I made it through the last 36 hours of shooting an entire 1000 mile stretch of the Baja 1000. Low on sleep (spent 28 hours in a car stopping to film 4 locations of the race with two being in the dark with floodlights at the pits), but grabbed some great aerials for the show. I stole the green board from my X8 and used it on my Octa with fine results. I have one more shoot tomorrow of the closing party down here in La Paz and will probably grab some scenic's down in Cabo over the weekend, but got through all of the important shoots without issue. Hopefully I will get some video posted up here soon. You can see how the Hoverfly, AV200 and skyline were able to handle strong gusty winds. I will say that the Octa is easily blown around though. It is amazing how stoked everyone is to see the multi-rotor fly down here.

Glad to hear you got footage and the Green board worked, cant wait to see what you got

#7 tahoelight Nov 19, 2012 08:42 PM

If you want to see the first footage we used so far, check out the video thread. I posted a link. Not a ton of aerials, but they really helped the cut and the clients were psyched we flew a camera.

Bummer, just found out HF does not offer this repair. :(

Congrats- same thing burnt on mine, same answer...I would expect them to at least be able to service their own boards!

I was told that this *may* be the part I needed (not by Hoverfly, by someone else on a different forum). May be worth a shot- it's only $3, the board is already smoked!

HF, it would be great I you could confirm this part. I realize the amount of time it takes to repair a board is not worth it for you, but if it is worth our own time, then knowing the right part would be a time saver. And, yes, we would have to understand it is at our own risk.

#11 S11D336B Nov 24, 2012 07:27 PM

That is the correct part. Just be aware that it will take some seriously skilled soldering to replace it.

Thank you VERY VERY much!

Good news. My Hoverfly Pro flies again. I replaced the part listed above and it works fine. A friend had the right tools and skills.

That's fantastic!
