I have a Swift 16 that was flying fair on a 13 tooth pinion and 515 Blades. However I recently stuffed my Swift and needed new blades. The only thing I could find was 530's. Switching to these blades killed the performance of the machine. Would lowering the pinion raise my head speed? I notice on the Century site they offer all their setups with a 9 tooth.

My current setup is:

Swift 16
600A motor
80 Amp speed control
2 - 4S1P 2100 lipos (I know the battery system sucks)

Going to buy better lipos someday.

Which pinion should I swap too?

Which will give me a decent run time and decent bail out performance?

What is the rule of thumb with pinions? Lower the teeth the higher head speed or the opposite?

I do not do heavy 3d yet. I am working on inverted hovering and flying at this time so I do not need crazy power yet.

Here ya go. http://www.swift-tuning.com/motors.php Plug your values in and see what you got. Then adjust the pinion to suit the headspeed you want. I must say though be careful running those pack with larger blades. You really need bigger packs. Are you running it in a 4s2p configuration or an 8s1p config? 600A motor Century Lightning 600 motor?

What 600A motor do you have - the 800KV 600A (black/purple case) or the 1100KV 600A Plus (silver/purple case)?

I used the pinion info. at the back of my manual of my 550 for my swift.

But, i'm using 550 blades and 6S 8400mah with a 600+ motor = 9 Thooth.

Works fine for me.

First, notice the page posted from the instructions posted by Ollie, that the smaller yougo in pinion, the lower the rotor speed (not mentioned is that yu will also get longer flights on the same batteries and get softer cyclic and collective response).

From what you said, it sounds like the power required by the larger blades take your batteries out of their efficient power delivery capabilities, cuasing them to deliver much lower voltage then speced at the higher loading.
