Can you post pictures of the heli? "Align 450" covers a lot of ground, a lot of years, and many, many different versions.
The 430L motor is a 3550 Kv motor (3550 RPM/volt) that was popular several years ago when the Align 450 had evolved up to about the point of being a 450 SE V2. Batteries in use at the time were generally 3S LiPo (11.1 volt nominal), of about 25C continuous discharge rating.
The Align 35 amp ESC was, and still is, a very good ESC to use with this motor.
By today's standards, the motor is a bit anemic, and not terribly efficient. Back in its heyday, it was THE motor to have in your 450.
Pictures of the heli you have would go a long way toward helping you with answering your questions.
The 430L was available in several Kv ratings. With some luck, yours will have a sticker on the bottom -- 3170, 3550, 2800...etc. I'm guessing yours is the 3550 Kv model.
