20mm by 40mm 4s motor?

[kacordy]

Where can a person buy a 20mm x 40mm motor that would handle 4s with no problem? Will the stock tenshock motor survive 4s? Will the stock 40 amp ESC in a Gen II handle 4s without a problem? I want to run 4s in a tenshock hydro. What KV could I use with 4s? What prop would be safe in SS and a source? I do not know how to calculate the 4s, KV, battery C rating, Prop D and P #'s, and ESC numbers. I really appreciate the advice and suggestions.

Thanks, Allen

I know of a few motors that will work on 4s that are 20 x 40 but you would have to get a different coupling for it which nobody to my knowledge makes. The stock motor would not make it on 4s nor is the stock esc rated for 4s. The second you plug a 4s into that esc it will blow. I recommend sticking with the 3s 2200.
