Question 450 feels "weak"...

Hey all!

I have a 450S with the stock Align ESC and 430L motor. Stock 325 carbon blades. The batteries I use are Cellpro 3S1P 18C 2200mAh.

The head is setup to provide -11/+11 deg. pitch.

Throttle curves are:
0-60-80-90-100 (normal)
100-95-90-95-100 (idle-up)

Pitch curves are:
40-45-50-75-100 (normal)
0-25-50-75-100 (idle-up)

I'm using the smaller of the two pinions that came with the 450S kit. I believe it's 12 teeth...

I've did a little bit of inverted practice today and noticed at various times that especially upside-down I need a lot of pitch to keep the bird from loosing altitude. I'm very close to maximum negative pitch actually, which means I don't have much left to do a climb-out when I need it.

Conversely, when right-side-up, it also seems like the 450 is lacking "punch" when I go full stick... Also, I do manage to bog down the heli every once in a while and make the rotor speed drop quite a bit during various maneuvers.

Mind you, I'm a beginner pretty much and don't require 3D performance. All I'd like is have a heli that can bail me out when I get in trouble. Plus I like hovering inverted a lot so I'd like to be able to do it more comfortably.

Sooooooo... What can I do to improve the "peppiness" of my bird?

I'm hoping it's something with my setup.
I'd rather not buy any new components. The 450 should be able to handle light duty like this without any upgrades, no?

Thanks!

Put an S curve on your pitch. And put a 13 tooth on it. ANd look into upgrading the motor. You will need some better packs too.

Put the13 tooth pinion on it. You probably have an 11 on at the moment as the 12 are an upgrade option. Bump up the TC in Idle UP to 100 97 95 97 100 or just have 100 across the board.

This will make it much harder on the Batteries but you should get the performance you are looking for.

My 450S CF kit came with a 12t and a 13t. I installed the 12t first and switched it out to see what the 13t was like and I never looked back. I am dealing with the same issues as you though were the heli just doesn't feel like it has that punch it did when new. I think my head setup is to blame but I won't know for sure until I dig in.

I'll keep you posted, My cheapo batteries may be to blame as well!

Put the XL motor in it. It makes a big difference. Good enough for bailing out. I already put it to the test with an attempt at inverted hover went wrong.
