Going from a coaxial to fixed pitch with a flybar is a jump. Coaxial to flybarless FP, a bigger jump. Coaxial to collective pitch, flybar or not, I would not recommend it..... Not saying it can't be done. You would just have take small slow steps to progress.
Flying flybarless, you have to counter act every input. Move the helicopter forward, let off the stick, the helicopter will still travel forward till you give it opposite input to stop the forward motion.
With a flybar heli once you let off the sticks, the heli will correct itself to a stable hover.
My first FP heli was the Blade mSR. Great heli, I would highly recommend this for indoor flight, or windless outdoors.

Do not be tempted to get the mSRX, flybarless version. It has some bugs in it that make it difficult to learn to fly.
Then I went to the Blade 120SR. Larger heli for flying outdoors in light wind. Again another heli I would recommend. This might be the best choice. Nice size and able to fly outdoors easier.

After having those heli's and flying them for a while is when I decided to make the jump to flybarless collective pitch helis. I will not go back. LOL
Here's what I have currently and my thoughts on them. (Smallest to largest)
I have 1 Blade Nano CPX which is a complete blast to fly and very tough when it comes to crashing. Of course every crash is different and I've always been lucky to let it down easy when I crash......
The cyclic controls are extremely responsive, to the point of twitchy. (Here is where a good computer radio makes all the difference.)
This heli holds its tail extremely well while inverting and pumping the pitch.
The main brushed motors in them suck big time. Some people only get 25 flights or so before they burn out. Mines been grounded after 75 or so flights. I cannot get a motor for it, there back-ordered. Hopefully they pulled all the junk motors and are making better quality ones.
I have 2 Blade mCP X. One is a ver1 and one is a ver2. I really cannot say one flies any better than the other.
I really enjoy flying these as well. Again very tough when it comes to crashing.
The cyclic controls are not as responsive as the Nano, you feel in better control, more forgiving....
This heli has tail issues. When inverting smoothly there is no problems. If you're not smooth or pumping the pitch hard, the tail can, blow out. This can be reduced with a good computer radio to change the pitch angle so you do not bog the head down so much causing the tail to lose hold. Another thing that helps tremendously with the blow out, Blade released a new tail assembly that is longer than the one that comes on the heli. This makes a big difference.
I saw a day or 2 ago they have re-released this heli with a brushless main and tail motor.....
Last helis that get air time is 2 Blade 130X.
These can be a love hate relationship.
Not sure how they do in crashes, been fortunate enough to never crash one. I also have not been brave enough to invert these helis either which has saved them from crashes.
They have lots of power from a brushless main motor, which runs the shaft-driven, variable-pitch tail.
They require lots of tweaking to fly properly, but when they do, these by far are my favorite helis I have.
Here's a picture of most of my collective pitch helis. I do have a 450 size heli that was supposed to be a last years winter project to get my gyro set up. Never happened.... neither did the 2 planes that need built in the garage....
