More troubles

[Mich. Maniac]

Hey guys. I am wondering if anyone has this happen and if yes or no what may it be. I am using an CC 80, 8XL, FM radio. Everything was going great until the end of my last run. The throttle started sticking a little and now I have done a bench test and when I give slight throttle it winds up and stops until I let off throttle and then it goes back to normal. Also the throttle is jumpy, not winding up steady. servo works fine through bec. ANY IDEAS>? please

Check your transmitter batteries. I had one act that way once with a bad battery. Transmitter was putting out a low signal.

Check the crystals and make sure the are seated. Make sure the antenna is screwed in all the way on the tx. Check the tention springs in the tx to make sure the batteries are seated snug..Look for corosion....try changing out the rx & tx crystals. Change the esc over to the stearing channel and test it. That may indicate a messed up channel. Then ya gota figure out if it's in the rx or tx. Thats all I got right now. I'll think some more.

If none of that works calibrate the esc to the RX again.

yeah, I checked that again. I notice the way it acts is pretty consistent. should i just run it? I would hate to hit a real boat at the dock. OR melt a lipo

[Mich. Maniac]

maybe 22v 6s lipo was tooooo much for the esc, motor, or I didnt think but maybe too much for external bec. wired to 6s liPo.???

Swap the channel cables on your reciever and see if the problem follows or stays the same. if it stays the same try a different controller. If it changes try a different receiver/transmitter. Try running it on a seperate receiver battery, disconnect the bec wire. I dont think I would chance running it like that.

[wickedgmc]

over 3s lipo the castle Hydra requires a separate battery for the receiver and to disable the bec wire from the esc. May be the same for the others

may be the problem you are having, get a receiver battery and remove the battery wire from the esc, not permanently though as you will need it for the castle link

Mike YES you are over volting that BEC. Go see Mr Hill @ BattlePack for an S-BEC. The Hex unit will not handle s6. I bought it for 14 Nhmh.

[Doug Smock]

I dont think I would chance running it like that.

[Mich. Maniac]

so I have probly officially burned my first rx. kinda a milestone.

[wickedgmc]

possibly, but I don't think so the reason for the erratic behavior was loss of power to the receiver. Get a receiver pack and try it that way

[Mich. Maniac]

Yes it is confirmed, I hooked up futaba fm and smooth as can be. Rx has been Fried. live and learn, thanks for the help

[wickedgmc]

well that sucks, at least it was not something more expensive. Glad you found the problem

I'm sorry for the problem, but perhaps we can make a positive out of this thread. Had the OP given us all the information about his setup - in this case the voltage - the answer would have been quicker coming. If you have a question about a problem, be sure to include all the information. In addition to the voltage, the prop used would be a must-have (even though it would not have mattered here). BTW, 6S is way too much voltage for an 8XL in anything but a SAW setup - it would have fried your ESC soon enough anyway. Frankly I'm surprised it survived, watch it carefully in the future. Damage can be cummulative.

Another lesson - RTFM. The Castle instructions and Specs clearly state not to exceed 12 cells with BEC.
