A few things: Think of the swashplate like the helicopter. If it tilts back, it's headed back, if it tilts forward, you're moving forward. That helped me a lot. Ideally, the swash should be perfectly level.
Once you get the linkages all dialed in, you can move the linkages IN (Towards the servo) one hole. This will make it MUCH less sensitive. One of the downfalls of the blade cp pro is the bell hiller mixing. It makes it REALLY sensitive, and it's difficult to learn when the thing is so sensitive.
Finally, the real secret is ALWAYS FLY the heli. If you start watching it, you're about to watch a crash. They are not stable birds. They require constant attnetion and correction. Your fingers should always be moving. This isn't to say that you shouldn't trim it. If it consistently moves one direction, or you finding yourself holding a direction, use the trims on the transmitter to compensate. The tail is adjusted via a potentiometer in the 4 in 1 unit. If the tail needs trim dont trim via the transmitter, trim the pot. Consult the manual which direction to turn the thing, I forget at the moment.
Finally, how you practice is important. Perfect practice makes perfect. Take some painters tape and make an X on the floor. Spend a few batteries trying to hover over the X at a constant altitude. This will make you a better pilot REALLY quick. When you have that mastered, do it sideways. And when you master that, do it nose in. Take your time, and master one thing at a time before moving on.
Things to remember:
Don't practice in "Idle Up". That's only for flying around, and you've got to master the basics before you do that.
If you're goig to crash, GET OUT OF THE POWER. Not only will it save you parts, but it will keep you from burning up the very expensive 4 in 1 unit. Some people have gone as far as to put 10 amp auto fuses in line with the motor. You don't need to do that, just make it an instinct that if you're going to pound it, throttle down.
That's all I can think of at the moment... I'm sure some more will come.
Oh, the last thing is, leave it as stock as possible. Hardened mainshaft is ok, and since you have the swash, no biggie, but don't be fooled into thinking shiny parts make it easier to fly. Wood blades, stock motor, stock battery is all you need to teach yourself EVERYTHING up to basic 3D aerobatics.
Some of the above may not apply to you, and if it sounds condescending, I apologize. I have no idea what your level of skill is right now, and I dont want to leave anything out.
WHat sim are you using?
