I'm about to program my CC120 but am not finding a file much like they have for Align and on this forum with the Hacker motor. Maybe there should this thread can contain information for first time programmers because different motors and gearing will have different answers in the software. I think most of the info I will know, but the pole count and a couple of other things I have no idea about. Hopefully Google will be my friend and I'll find those answers. So, hopefully some of our resident experts can input their settings to help the future Synergy family members.
I may not have all the answers, but I'm the guy that can come up with questions that may help! lol

Look up your motor on the Scorpion web site, you will find the pole information located at the bottom of the page in the specs section. Below are the specs for the Scorpion HKIII 4025 1100KV. I realize that you are not running this motor. This is just an example of the information.

Gotcha, but I needed the info of what to put into the programming. I'm looking up info now, thanks! I'll probably have to leave for the gig before I can finish. Took forever to figure out how to program the bec pro. Still learning but at least I have that done. Put it at 6.9 right?

You should be running your BEC at 7.4V as all of your servos are HV if I remember correctly.

You should be running your BEC at 7.2V as all of your servos are HV if I remember correctly.
Rich
HV servos are rated at 7.4V and you would see some loss in the line so I'm not sure why 7.2V. A fully charged 2S lipo is 8.4V so HV servos can actually handle that too. Then you have this: http://www.helifreak.com/showthread.php?t=345971 (http://www.helifreak.com/showthread.php?t=345971)
So, to me you should be at 7.5V (which is much better according to the HF thread as it's a .5v increment) or 8V would be fine too.

Chumley is correct I apologize. I will correct my post. I was trying to do too many things at once. Good catch Chumley!

Ok I will change that. Haven't hooked up servos yet. So I need to reprogram the bec to 7.4 or 7.5 then.
-
What I have gathered is you set the BEC V to what the servos are going to run. 6 or 7.4. I did notice on www.Helifleet.com that Matt was running his E7 at 6v (when it was posted that is). Great site by the way! I'm thinking of 6 or 7.4 I guess it will depend on how it feels once I get it in the air (servo to fast or slow)

I just set it to 7.5v on the bec pro. Loaded the settings sent to me from wbfines, thanks man! I could only govern at 2200 because of the calculation given. I will try it at that for now but would like to increase it to 2400-2500 eventually. I could have sworn Matt said in one of the videos with the same setup other than I'm running vbar that he was running 2500 head speed. How can I do that? Hopefully I can just get it in the air by Tuesday.
-
What settings? Can you send to me I'd like to take a look as I'll be running the CC 120 and running gov mode as well. I would imagine you would need to change the pinion to a higher tooth count to get a higher head speed.

You can run the 14 tooth pinion to increase you head speed but, at the cost of shorter flight time times. As far as the calculations in the CC 120 they are very conservative. On idle up two (assuming you have normal, idle up 1 and Idle up 2) you should be around 108% on the Castle. I highly suggest you fly the helicopter at head a speed from 2100 - 2300 before moving up to 2500. The E5 will perform every maneuver in the book at 2300.

NY, pm me your email so I can send it to you. Fines, is that ok with you?
-
Yeah, that's why I stayed conservative with my headspeed for now and kept it at 2200 and then I will up to 2300 and maybe every few months bump it up when I get very used to it. Right now it will just be nice to get it in the air before the rain arrives later this week.

Not a problem :)

Thank you so much for sending it to me, really helped a ton!
-
No problem. Glad it worked. Once you get used to your Heli and if you decide you want more HS, there's a couple little tricks into getting a little more. Like others had mentioned, 2200-2300 will fly great and do most anything you ask. Good luck on the maiden.
-
What are the tricks? I think it should be a little higher, I think it will help with the small wag I have. Maybe raise it to 2300.
-
Wag is caused by by not having the gain set properly either on the transmitter, gov gain in CC software, pots on flybarless controller, or vibrations which I would find hard to believe on this kit. I'm jealous you have already flown the Heli, congrats! The first couple of flights are always about tweaking to get rid of those wags. Once you get it your good though. Not sure on the V bar settings hopefully someone can jump in and tell you what to look for. As a general rule of thumb if you are getting wag some gain needs to be turned down.

Here are the settings I put in the CC software for the 120HV2. I put in head speed of 2100,2200,2300 and this is what I came up with. I plan on using the 14 tooth pinion at first to see how that is unless everyone thinks I should use the 12. I fly mild 3d but have plans to really work on my smack with this machine. Thoughts suggestions or comments with this speed controller? What works what doesn't for you.
-
Well a slow "hunt" and a fast wag often have different causes. Yes gain can cause both and normally addresses both. But you need to make sure the tail control system is setup as well as possible. You want the control rod and linkage to be free of binding. This usually means sizing the control rod links and the links on the tail blade grips. You should also lubricator the tail shaft. This makes the brass collar in the pitch slider move easier.
Check to be sure the tail control is smooth them play with gains.
Yes vibrations can wreck a gyro but in my experience the swash plate shows vibrations more than tail but i could be just that unlucky.

Well said thanks Chris. Can someone please tell me a good number to start with on the Gov gain in CC software. I don't have a lap top to take to the field and be able to adjust. What is working for folks? Please tell.
-
On a TT heli, I set the Gain to LOW. Higher than that and you risk the TTs stripping. Now on the E5 the TT are MONSTER so you can probably go up some, but for a start, I would set to low and fly it. If the head speed is holding good, leave it. If you need a bit more go into custom and go up 1 or 2 numbers at a time.
-
I think I have my gain in CC too high. I left it as it was but I also got a messsage from wbfines and will adjust to that. Also, I 'm sure my headspeeds were too low. Won't get to see if anything worked for awhile though.
>:( :(
-
I know I read...sorry about that, I hate it when stuff like that happens. Live and learn. Regarding a low Gov setting in CC what would I look for to see if the head speed is holding? A bogging sound, log data. I'm going to use the 14 tooth as that seems to give me a sweet head speed between 2100-2350 in CC software

I tried changing the battery voltage to 3.9 but it wouldn't do anything. How would I change it from 3.7 to 3.9?
