I'm flying a century hawk pro with OS50 hyper, 15% cool power, 600mm century blades. I built it 4 -5 years ago as instructed by manual. The other day I was watching a buddy flying his raptor 50 and his helicopter can shoot straight up from a hover fairly quickly. My century goes much mildly compared to his. I thought maybe it's my collective servo. It is a hitec 7985MG -I believe it has plenty of torque. Could it be the see-saw set up. I remember the manual stating to use inner hole for beginner and outer hole for 3D. Question is, which hole do I use. On my seesaw I have 2 holes on the blade grip side and 3 holes on the inner side opposite of the other 2 holes ( in between is the fly bar). My head speed is approx 1950. It's gotta be the pitch of the blades. I'm thinking somehow my buddy is getting a quicker response to pitch change and mine is slow or not getting enough + pitch. On the ground it shows + 11 and - 11. It's acting like I'm only getting + 7.

Does your buddies have a flybar? If so use the same setup he has. If not that may be the difference.
I would also give the outer hole a try for 3D as the manual stated.

Running Governor??
Do you have your engine set up properly to increase to handle the added pitch?
If you are running gov. you should be OK but if not is your engine loading if/when you hit the pitch quickly?! If it is increase the values on the throttle curve.. in idle up you should be running a v curve to keep the rpm up to the job..
IF all of this is OK then I would work on the head so that you will get increased travel values...but make sure your engine is set to handle the added loads first..
Good luck

Thanks, will give it all a try. Don't have a governor and it is a v curve. I'll keep playing around with it.
