Re: pic: Custom 3 CIM 2 Speed Gearbox

My FEA gave the middle pinion a safety factor between 3 and 5, but it will be something that we inspect regularly. We're designing a drivetrain that should generally avoid pushing matches, so I'm not too worried about it, and if it does break, we'll have weeks to fix it unlike in the build season. I think 254 may have done something similar last year (2013) in their gearbox with a dual loaded pinion, but I'm not certain if they did or if it worked well.
