Propeller Calculator Links?

[FighterCat57]

I did a search and searched Google, but didn't find any.. I recall seeing a calculator somewhere where you enter cells, Kv and amp draw and it gives a prop spec.

I'm curious as to what prop might work well on 3s or 4s, 2700Kv and only draw about 80-100 amps in a 30" mono-cat.

Right now I'm using a 38mm two blade and it's getting a little hot. I didn't measure amp draw on it yet.

FEcalc is the software that does the job!
2700KV is perfect for 3S but if you consider you need 1000W constant to go fast, that's 90A and probably 110-120 burst, this setup is appropriate for a 25" that require a smaller prop than a 30" one... or for SAW.
2000 would be better under 4S, with the same statement as above (1000W) that less amp, around 70, and something like 100 burst (that's what I get on my 29" mono and that's my exact setup) it would give the same prop rpm as 2700KV/3S, a 42mm prop is appropriate for this setup, at least a good start.
