You're not providing anything beneficial to this thread. We are aware that the Jazz's gov mode requires less setup and may work a little better, but there are a lot of people that already have the Phoenix ESC and are willing to spend a little time to set it up properly. Once it's setup, it works excellent.
Sorry, but believe he "was" contributing to this thread! It's important for new people to know that there is an excellent ESC out there that works without a lot of complicated and frustrating screwing around. Sure the CC ESC is reasonabily priced and after you buy the option for computer connectivity, it is easy to make program changes. However, how much is your time worth in jacking around with finding the "just right" settings that work well with your particular motor and radio?

BrainDrain is dead on, program the Jazz in 3 minutes and fly. Always great governor performance! Read all the threads here about time spent in getting the CC35 right to work in governor mode. I would offer that the Jazz for many would have been "cheaper" in the long run! And thats not even mentioning the benefit of a switching onboard BEC which does not overheat like that on the CC35 which causes many to also buy and run a separate BEC!

Point taken, but, this thread has been about helping people that already have the CC35. I agree that the Jazz is excellent. A simple search will reveal that the Jazz is the ESC to go with if you're just starting out, but if you already have a CC35 and/or cannot afford the price of the Jazz, the CC35 is an excellent alternative. With the latest firmware, the gov in my CC35 is working as well as my friend's T-Rex equiped with a Jazz. The main difference is the setup. I already had several Castle ESC's and the Castle Link USB adapter when I got started with my T-Rex. I wasn't about to spend twice the money for something that may work a little better than something I already had.

Now, back to our regulary scheduled program...

i have been working with the cc35 gov mode for a couple of weeks now. KamikaziRcPilot's posts have helped me out alot. but, i still haven't been able to get the gov to work as expected. i followed the setup instructions on cc website to the T (set the throttle endpoints correclty). the gov maintains headspeed very well and will hold a consistented hover without bobbing. my problems is that the power spikes randomly and this causes the tail to twitch. the 401 does a good job of controlling it, but the tail still slightly twitches. the power spike is hard enough that you can hear the shock on the gear train.

i have my rex setup for duration (small pinion, low headspeed). i started out at 2100 rpm. with the 430L (3550kv) and a 11t pinion, this equated to 47% throttle in gov high. gov low only created 1600 rpm at 100% throttle. i tried the whole range of gov gain settings and 19 minimized the power spikes but didn't eliminate them. i also played with motor timing and throttle response without any success. so, i started raising the headspeed and was finally able to eliminate the tail twitching, but i it didn't disappear until the headpseed reached 2600 rpm. i don't need that much headspeed rightnow and i don't want to waste the extra power.

so, i tried a lower kv motor (450th, 3000kv). this didn't help at all and i had the same issues at low headspeed as with the 430L. i've switched back to curves for now.

for you all that have the cc35 gov working well, i'm curious to know what motor/pinion and heaspeed you are running?

Medusa 28-32-3400 with 12T pinion. Have you adjusted the "governor gain" at all? About how often do the spikes occur? (every 5 seconds, 30 seconds, 2 minutes, etc.)

yes, i stated in my reply that i tried the full range of gov gain settings. it spikes randomly, sometimes a second in between, sometimes five seconds, sometimes it may go 10 sec. it doesn't really cause any problems when doing FF/FFF, but i'm worried it may cause problems when i get more into 3d.

kamikazi, how much headspeed are you running?

kamikazi, thanks for the info. last time we spoke about the cc35 gov, i seem to remember that you were helping a buddy setup a rex with the 430L at low hs and were having problems. did you sort them out?

is anyone else running headspeed lower than 2500 and not having issues with the cc35 gov? ifso, could you share your settings. from what i've seen, not too many guys run low hs.

Ok, you are right I was just complaining and not helping. What are the setting to make the cc gov work like jazz gov? I was never able to achieve anything close even with the newest firmware and several hours of fiddling.

CC esc.....

Hey, I just got off the phone with Castle Again....their customer support and tech support is great!...if you have any questions I'd just give them a call....

I managed to get my Gov. mode to work great on the 85hv after a couple calls and a couple days of fiddling...

ktm520: I believe that his problem is related to the fact that he's running the tail reduction gear. I don't feel that the reduction gears should be used until the head speed crests the 2800 or so level. Head speeds lower than that slow the tail rotor down too much, then it struggles to work properly because the tail isn't responding quick enough to what the gyro is trying to accomplish. Mine does the same thing to some extent when I'm in normal mode at 2400 rpms. It's fine once I flip to idleup1 or idleup2.

BrainDrain_dx: No problem, I just get a little irritated when I'm trying to put out a fire and someone helps by handing me a gas can. There are no "best settings" for the Castle governor. It's going to vary based on motor, pinion, etc. You have to walk through the setup on the transmitter and ESC. I've worked with four friends that tried to set it up on their own without prior experience. In most cases, they were doing the right steps, just not in the right order. As mentioned above, I'm putting together a document of what I've found to be the correct order of steps. I'm going to walk completely through it today after work and compile a document that I'll post. Anyone/Everyone's welcome to review and add/delete/correct anything they find. I'm just trying to provide some help based on my growing pains. I didn't have anyone to help me when I got started and it was reeeeeeeeally frustrating.

kamikazi, its good to hear that someone else is seeing the same thing as i am. like i said, the gov works good if i set the heaspeed above 2600 rpm. i'm not running the tail reduction gearset. i'm going to call cc's tech support and see what i can get out of them.

if i was running high headspeed, i would have had no problem at all setting up the cc35 for gov mode. the hardest part is fine tunning the gov gain.

The Castle recommended gov gain for the T-Rex 450 size heli, I believe, is 50, but my head speed fluctuated quite a bit at that setting. I turned mine down to around 25, then gradually incremented it until the head speed started to vary, then backed it down a couple of numbers.

For setting the end points...I thought I should set the low end first... so I get the Esc to arm itself? Then set the high end?

This is awsome guys! Lots of great info in here for how to do it!!

Kamikazi, I cant wait to see what you put together when it's done! Now, here is the real question...

When I first started this thread I was asking how many people run the Gov mode and if so...Why? Im debating on if it will help the preformance of my rex and how it will help. Im not doing 3D yet and still consider myself a beginner with all this stuff. The reason Im asking is because I love learning about all this stuff and after getting my rex tweaked JUST RIGHT I'm curious if there is anything else I can do to tweak it just a little more for a much better flying bird.

Again, love all the feedback on how to set it up!

CC vs. Jazz

I bought my CC 35 with my first Trex over a year and a half ago. I tried then to set up the gov and it never worked right. Then, a couple months later I bought the link cable and downloaded what would be the first of many software updates which......did nothing to fix the governer problem.
I still have the CC 35. However, buying a new Jazz esc whose BEC does not cut out constantly and crash my heli ended up being the easiest fix for the governer problems on the CC 35.
Take that pizza delivery job. Find a rich guy to do the "indecent proposal" thing for $ with your wife or girlfriend. Hock your favorite underwear. Just do what you need to do to get that Jazz. You won't regret it.
The CC35 is fine for a 3D foamy plane, but I wouldn't waste the time it takes to plug in that computer link to ever use it for a heli again.

I'm standing at my workbench right now. I've just finished going through the entire governor setup. I'm going to work on the documentation next.

In general, the use of governor mode should simplify the setup process because it saves tweaking throttle curves to get a head speed that's consistent. It took Castle a while to get the firmware to a point where it's working very well. It's been a rough road, but it's paid off. I started wit m T-Rex 16 months ago, back when the governor wasn't worth messing with. One of the main things I like about using the governor mode is that the head speed stays consistent throughout the flight. This is something that throttle curves cannot accomplish. While using throttle curves, the head speed will slowly drop as the battery voltage drops. Governor mode compensates by increasing the amperage.

You hear people say that governor mode isn't as efficient as non-governor mode, and because of this the flight times are shorter in governor mode. It's not due to a lack of efficiency, but due to the fact that the governor is doing exactly what it's being told to do: maintain the head speed. I would rather have slightly shorter flight times with a heli where the head speed is the same at the end of the flight. My T-Rex handles the same throughout the flight, and I really like that.

I've used both curves and governor mode. IMHO, unless you are a 3D pro with great collective management skills and the knowledge/feel for fine tuning curves, the use of an ESC with a great rpm holding governor mode can't be beat! I'll never go back to curves on the Trex. A primary benefit of a good functioning governor is consistant motor performance and control feel throughout the flight, as the ESC manages battery output to maintain HS.

This is a benefit which will help your flying!

Inspector Fuzz: At some point Castle started incorporating dual regulators into the CC35 BEC. I know that the CC25 more received that upgrade in the last 6-12 months or so. I've flown many, many flights on mine with a data logger connected between the ESC and the receiver. The in-flight amp draw has never risen above 1.28 amps no matter how hard I've pushed it. The in-flight voltage has never gone below 5.28, which I see as a clear indication that the CC35 BEC isn't being pushed near its' limits. I can see using a separate BEC if I ever go to all digital servos.

You may have just had a defective unit. I've run across Jazz failures too. True, every device has a limit, and it's possible to have a heli setup incorrectly to where there's servo binding and so forth, which will greatly increase the amp draw. If a CC35's BEC is designed to handle a 1.5 continuous amp draw and it's subject to more and fails, I don't fault the device. If you put tires on your car with a low speed rating, then exceed that rating and they explode, do you fault the manufacturer?

I think that the specifications are misleading when it stated "BEC (3A)" on the packaging (I still have mine!). It can handle bursts up to 3A, but the continuous rating is much lower. I wish these things were explained up front.
