Default Castlelink gov mode settings

Hi guys,
I have a tr550 dfc running with a scorpion 890, 112 main gear and 13 pinion, Talon 90 esc, and put about a kilo of weight on to try and replicate a scale fuse. I have purchased the Castlelink and downloaded the program. My dx7s is still setup with the "normal" Th curve which I have been flying with - 90 90 90 90 100.
I have set the Castlelink gov mode to 1555 (75%) 1730 (84%) 1850 (90%)
2 q's before I try her out -
Do I need to reset my Th curve in the Tx
and
What do you think about my gov settings.

The instructions tell you how to do it.

Normal = 0, 30, 30 = Speed 1
ST1 = 60, 60, 60 = Speed 2
ST2 = 100, 100, 100 = Speed 3

The actual throttle setting bears no relation to the throttle % - it just tells the ESC which speed to use.

BTW, 75% governor may result in heat in ESC unless you are in Tassie

My guess is that you would want to run around 1600rpm for a two blade 550 (I run 1800rpm on my 2 blade 500 UH-1N), so you would be thinking about gearing to try to get around 1700-1750rpm at 95%, which is the highest speed you can govern at, and try not to go below about 85%.

I thought the instructions state 70% for St1?

I am also sure the setting is 70% for the Idle 1 speed. Farmer Joe, consider using the 12 or 11t pinion for your setup. I am running my Jet Ranger with the same motor but slightly different gearing at 1450 rpm. You can easily get there with the 11t pinion. I am using a set of Pro 3D blades and at that rpm level, I could do some mild aerobatics (I don't though) as there is lots of power and this will also fly very fast. I changed my gearing to one tooth larger and the change was very noticeable in speed and power consumption. I am thinking of going back to the one before as it was smoother and used less power at the exact same rpm level. I can't figure that one out. Hope this helps.

Throttle curves will be different depending upon which governor mode you choose to run.

Not if if you use set RPM..
Normal/30%
Idle1/70%
Idle2/100%

Exactly, it depends on what you want to accomplish.

If you want to be able to change head speeds via throttle curve (outside of Castle Link), then you don't want Set RPM Gov mode. You would choose Gov mode High (depending upon your target RPM). You can only change head speeds for Set RPM through Castle Link.

The reason I choose Set RPM is so I can easily clear the data logging in the field via the transmitter. Yes you could probably do it in Set RPM as well, but it would call for changing at least one point on your throttle curve to 100% every time you wanted to do it, then changing the curve back for flying.

Thanks for your reply guys. I made a few adjustments according to your recommendations and she flys great. The gov really takes that bounciness out of flying.

By the way Keyrigger, next time i order parts i will take your suggestion re gearing. I want to get a little lower headspeeds but with my current gearing i suspect i will overheat my motor.

Thanks again,
Joe

They might. From memory;

Speed 1 = any % between 1 and 50
Speed 2 = any % between 51 and 99
Speed 3 = 100%

So in Set RPM mode (which is what I thought the OP was referring to), there would be no difference between a 52% throttle curve and a 95% throttle curve.

Happy to be corrected

If the motor has a 5mm shaft then a 12T pinion might be OK, but not sure about 11T. For a motor with a 6mm shaft, I would strongly advise against anything smaller than 13T. There have been several cases reported in this forum (including one of mine) where a 12T 6mm Mod 0.7 pinion shattered. It is because there is just not enough metal between the root of the tooth and the hole.

The Mod1.gearing of the slant type with the 112t main gear is really heavy duty, unlike the Mod .7 gearing of the older systems. I even have a 10t pinion and it is really solid for the Mod 1. There is not a snowflake's chance in Hades of the pinion shattering. I have the 10t pinion because I saw it and figured that it may work to increase the speed of the motor further into its power band yet keep the rotor speed at 1450. It is running at 80% governed. Take care.

Thanks. I wasn't aware that the OP had Mod 1 slant gearing on his 550. There are a few different version out, and many 550s have the same gearing as the older 600s, with 170T Mod 0.7 straight gear.

It gets better. There is a slant gear Mod .7 out there from Align as well. Just like its straight toothed version, it is also subject to the really tiny webbing in the smaller pinions. You don't see too many of those in action around these parts as most of the older helicopters used for 3D have been relegated to the basement and replaced by updated versions. I know there is a ton of old 600ESP's out there that can be reworked into really nice scale chassis'. Give it time and they will be on the market when the next generation hits and the guys looking for those older ESP's and E's will have a field day snapping them up. Of course, one could always hope......
