| You don't need a governor. Your problem is how you have your throttle and pitch settings. In normal mode, you don't need anymore than -3 on the bottom and as for the 10 on the top that's cool although if you want a higher head speed with more pop and less of a load, 9 will work. Now back to that crazy throttle curve of yours.
Some people are lazy and don't want to do the work of setting the proper throttle curve so they buy governors. Now setting the correct throttle to pitch takes two people. One person to fly the helicopter and another person to run the digital tach. Now if you follow what I say, you will have minimum bog. You have a few things to consider. Motor Kv, volts, pinion, gearing. Here is a little formula for you. This is going to be without a load, giving you the maximum possible RPMs.
RPM=(volts x Kv x pinion)/main gear
Ok, back to the fun. Once you have an idea of what you think your RPMs should could be, have your friend set it on the tach. Now switch to the throttle channel on your TX and spool up to 0 pitch (we'll say 1/4 stick is 0 in normal). Now increase or decrease your throttle to match the tach. Once you have this setting, make sure that your other throttle settings are higher than what your 0 pitch throttle setting is. Now keeping the same head speed on your tach, lift off the ground and go to a hover (let's say center stick). Have your friend tell you how to adjust you throttle to match it. Now time for more fun. You high throttle should be set to 100. It is now time for a climb out test. This is where the real settings are dialed in. Go to 0 pitch and have your friend check you. Now go to a hover and have your frind check that. The goal is to not drop more that 100 rpms doing a climb out if so have your friend track you head speed because you slowest head speed on your max pitch climb out is going to be your head speed. Keeping that in mind we have 5 pitch and throttle curves to to play with.
Lets say this is your setting
-3 pitch and 0% throttle
0 pitch and 50% throttle giving you 1850 RPMs
4.5 to 5 pitch and 75% throttle giving you 1850 to 1870RPM
INH pitch and INH throttle because you don't need to set it
9 to 10 pitch and 100% throttle giving you, lets say 1700 on a climb out.
Now these setting are just for an example. So now that we see that we dropped RPMs on the climb out, it's now time to set your 0 pitch to your lowest climb out RPMs.l Then set your hover RPMs to the same.
Now if you want to set your CV-P3 position, you can but you really don't need to. Now that you have it set, go to a hover and do a climb out, you should have no bog and your heli should be flying better and you should be getting better flight times and less heat. Now you are going to want to try to speed it up on the lower end, but all this is going to do is creat bogging and generate heat. If you desire a higher head speed move up a few teeth with our pinion, but keep it in the safe range and then go through these steps again.
Now if you really want to dial in some power, you can do some mixing. Al to Th and El to TH mixing in about 10 to 12 percent. This will cause your helicopter to increase the head speed when you are turning and stuff. example: You have 1750 head speed, and you fly forward all is good, now you go into a turn, your head speed drops to 1700 and then goes back up. Now when you add in the mixing, you can increase the throttle mixing so that it doesn't drop.
Well, I hope this helps you and I'm sure someone is going to disagree, but I'm just trying to help. Have fun and Keep It In The Air.
