Thanks for that
The $ cost of the motors etc is not a problem. But if these won’t work then I will be in another place

For clarity, I’m not convinced that these motors are big enough. I think they will be operating at their max power rating to get close to what you want, but then you’re only looking to run for 20 seconds at a time under load. This is why I say you’re in the land of practical experimentation
