Default 450 XL has lost it's POP ...... ???????

After reparing my 450 XL from the last crash my heli has lost its pop or the inability to react to the throttle input.It reacts but it does not gain altitude the way it did before the crash.Here is my setup:

450XL with 430 motor and Align 35esc
325 Fiber Blades
RPM is around 1900.....

Pitch Settings JR 6102
1@ -2 degrees
2@ 2
3 @ 6
4 @ 7 1/2
5 @ 9

Throttle Settings
1@0 %
2 @25 %
3@50 %
4@75 %
5@100 %


Any suggestions ?

Your throttle curve should be more linear -2 -1 0 +5 +10 that should liven up your flying...

I'd bump up the throttle, 0, 50, 75 90 100 maybe
The first 2/3 of your actual throttle range is just getting to the proper rpm range, so you're really only going to use that last third, might as well put it where you can use it. That head speed seems kinda low too, if you want pop. That might be good for scale style flying but for zippy performance you need more head speed.

Remember to check for any binding, overtight gears, overtight belt... the usual stuff. How's battery life? How many cycles on the battery? any puffing? that kinda stuff.

It will fly like crap down there... get it AT LEAST to 2300 to 2400......

I fly with mine at 3000, but I'm just a bit odd!
