Anybody want to try this Calc ?

Figured i would post this up,it is a calc a friend of mine put together.All you have to do is fill in the top portion,and it will take care of the rest.....tell me what you think.I punched in a few of my combos,and it was close. http://rcwebclub.com/PropEngine.aspx

I ran this against a few others,and seems to be around a 10% discrepancy...But like anything,all is a work in progress.What do you guys think ?

If you want it to work for an F5B setup you need to allow for a lot lower volts per cell. It's 33% out against my logged data because I can't put in a realistic cell voltage.
Mind you 9.4kW in a B08 would be a lot of fun

Chucked on some numbers from my setups, speed is pretty much bang on the money, amps show quite low and the estimated flight time is close to double what I actually get.

Nice calc, quick and easy, will be useful. Thanks Voodoo.

See,this is a good thing,he mention things might be off,but speed is what he is looking for.Good chance these are things set in the program for the speed to be correct,i will be talking more to him about it soon.Thanks for the feedback.

Speed is bang on for my setup.. flight time is 5 times longer (if only I could fit a battery bigger than 1300mah so i could get longer than 2 minute flight times), and amps are a bit higher

Flightime and speed came out pretty close. Amps were a little low and voltage a little high.

Don't know what a Pound is
