So I a building a swift 550 carbon and I have a concern with the pinion suggestions in the manual. The motor I have is a 1100 kv with a 6mm shaft. On 6s century suggests a 9t pinion. Is that right? I am afraid of stripping with a 9t. I also cannot find anything less than a 10t for a 6mm shaft.
My swift 16 had a century 600 plus on 6s but I cannot remember the pinion size.
Are there any other main gear options out there?

Thanks for any help!

I would say run the 10t. Doing the math with your 1100kv motor on 6s should give you a max rpm of just over 2100 figuring 85% efficiency. I am running an 880kv in my Swift NX on 6s with a 10t. I am only getting a max rpm in the high 1700 range. That is fine for my flying style. I get about 12 to 14 minute flight times out of a 5000mah pack.

The world is yours!
