I didn't design that circuit, nor do I often use op amps. But I'd get an LM324 - it's a quad op amp (and you need at least 2 for your sensors). It has good input voltage range so you should be fine.

Thank you!
So with that chip, I would build two sets of circuits, each passing through the single chip, effectively utilizing half the LM324? That sounds straightforward enough.

Yup, sounds good. The single chip cuts down power wiring, which might help the signals look cleaner. Just make sure not to cross the outputs or something--pinout is straightforward but doesn't follow the usual standard of one corner ground, other corner 5V.

Since I don't know "usual" that assumption shouldn't bite me Thanks!

For the purpose of the 6wheeler ATV i would suggest you get a Buick lacrosse ACIM motor and use it for test bed.
It should provide 18kW for your ATV and you can easily adjust belt drive...
It is also a good unit to learn basics of resolver control. I have one here and I need to test how resolver works with ACIM sine code.
Mr. Kelly has also dissassembled one on youtube .
Thanks for the recommendation, but the transmission in the 6x6 was my main problem, I got the 2-stroke to run alright, so using an electric motor and keeping the belt would not solve my issues with the 6x6 Plus you mentioned it requires fairly high voltage worth of battery to make it run, and I'm not sure I'll have that much battery power any time soon, or even on the 6x6 itself. There is a guy on a Facebook group I'm in with a 6x6 that would like to just replace the engine and keep the belt, so I'll pass the recommendation on!
