Title: Arun lifeboat motor options
Post by: lankyandy on August 05, 2019, 11:13:39 pm

so I have been reading the forum for recommendations but just wondered if anyone had any experience with the turnigy sk3 range?
I’m building a 1/12th Arun lifeboat. It’s on 50mm 4blade props from the prop shop. I have found these 3 motor options but wondered if you have an opinion on which would be ‘best’.


Option one

Or option 2

Or option 3

Thanks for any guidance
