Castle Creations and Futaba 7c 2.4
Need assistance or advice getting a CC85hv to work with a futaba 7c 2.4 Radio

Here's a run down
Trex 500
R617fs
GY401 w/9650 on tail
z-power z30 1110kv motor
6v ubec
futaba 9650 servos on cyclic

been working on it a couple of days now and all servos are working. According to Castle Creations manual sometimes you have to reverse the throttle to allow it to arm. Obviously it didn't work. Any advice would be appreciated.

Reverse the throttle channel -- you have a Futaba radio, then adjust the throttle channel endpoints to get the ESC to arm the motor.

The ESC most likely isn't seeing the throttle channel go "low" enough to arm.

While you're at it, disable the CURRENT LIMIT feature unless you want random motor shut downs in your heli.

Yep, Futaba radios need to reverse the throttle channel with every ESC I've ever seen.Andy

Thanks, I'll have to read up on how to disable the current limit - not sure where I would find that in the radio. Thanks for the info. This might save a 40 mile trip to Atlanta to have it looked at.

RR is a great forum and I appreciate everyone sharing there expertise.

Current limit setting is NOT in the RADIO. It's a CC ESC setting. You'll have to read your CC85 manual.

Setting number 2, option 5 in the CC85HV manual.

Simple if you own a Phoenix Link cable, a bit more difficult if you have to do it using the standard stick programming sequence.

Since my very first experience with electric was... well.. a bad one.. I'm always scared to use stick to change settings on an ESC... I had a flying wing that was my first electronic flyer, and didn't have the motor mounted, just connected.. with blade... yeah.. you see where this is going... I wanted to make sure that the wires were connected in the right direction to turn the prop the correct direction. So I turn it on with stick all of the way up (According to the ESC manual, you had to have the stick at full to put the ESC in programming manual. Then when you hear the series of beeps that match the setting you want, you drop your stick to 0). The only problem I had.. I was using a futaba radio. Powered it up with stick at full, reverse was not on. Instead of enterting programming mode, I entered normal mode and engaged the ESC.. heard some beeps but couldn't get it where I wanted it, so I thought "Maybe if I stick down it will fix it"... Nope.. full throttle on an unmounted motor with a 6x4 prop on it. Made a nice hole in the plane as it skipped and jumped accross the brand new plane, missing the surface placed battery, and my hand by maybe half an inch. Scared the crap out of me. Now I don't do any ESC programming with a motor plugged in, and on my very first setup of an ESC, just to make sure it does in fact have to be reversed on my radio, I mount it, but don't place any blades or gearing on it.

Thanks the advice
Guys I can't say enough thanks for the advice here. I will definetly unplug the motor. Don't have a cable for the EDC so I am have to going to beep it. Since I have never done this and need to go to Atlanta anyway I thing it mught be best if I have the a Pro I know down there show me. One thing on the Futaba is up reverse or is down reverse. The reason I ask is my radio is already programed for my Trex 600 with a stock ESC and BEC and I copied the Settings to a new model for the Trex 500 w/cc85hv ESC.

FLying the 600 is a breeze - Hope this 500 Flys as well - I have heard they are the perfect combination for quickness and stability

You must have a really old radios. Most programmable radios out now will have an LCD screen and will state "Normal" or "Reverse".

I took it down to Atlanta and turned out to be the Throttle Trim - Had to bring all the way down. Everything is workng now. There is one thing that concerns me. After running it on my garage floor to check everything out since its raining heavy today. If I turn off the radio the heli starts to spool up. Turn the radio back on and the thottle shuts down the heli. Thats just weird. I will just have to remember to unplug the battery before shutting off the radio. If you have any ideas I would appreciate it.

Word of the day - Helicytus - An infection of the brain and thumbs that supercedes all other daily functions. Signs and Symtoms - When nothing around the house gets done because tweeking the Helis takes precedence into the wee hours. Cure - No cure known

NEVER turn off the radio before you unplug your electric plane/heli. Standard procedure should always be to turn off receiver side before transmitter. When you cut off your transmitter first, your receiver kicks into failsafe mode. If failsafe mode says throttle at 50% than so be it. Your failsafe could also have elevators/ailerons at full up, full down, level, who knows. Some ESC's have their own built in fail safe mode too. If you bought it used, who knows what it's set to, and if you bought it new, it'd be set to factory defaults (whatever they may be for that device). Regardless, You're in essence cutting off communications with an automated loaded gun, and when it loses communication, it doesn't know what to do, so it reverts to a default mode, and that default mode might be the trigger pulled. Be safe and unplug battery first.
