Flexshaft size for 1/16th hydro

[JimClark]

Not too smart when it comes to flex shaft's. Was wondering what size would be good for my 1/16th hydro project? Motor will be the Leopard 2845-3650 on a single 2s but may try a 3s pack once in awhile just for kicks

I use .130" flex on 28 size motors, ive used Octura .098" flex & broke them. Maybe ok running under 30,000 but I was running around 42,000 rpm unloaded.

Agree .98 flex might do a 28mm motor but wouldn't go any smaller than .130 myself and the hughey cables are well built
