yes well my very first go at electric and EDF and I did state the assumptions used. I'm on the learning curve so don't shoot me down too soon.
All theoretical calculations based on what I think will happen. As with any engineering scenario one has to state the parameters that are used as basis of canculation.
i.e flying at an average of say 50% but realistically bank on say 80% throttle average.
I did also point out that I expect inlet losses to bring throust to weight ratio down to about 1:0.75.
Tend to agree that the weak link is the ESC and that the lipos will supply more then ESC can handle and that the fan motor is like to exceed it rated power consumption.
Have to start somewhere and see how it performs, or doesn't. 3 mins then land and charge the pack to see how much it take to charge back up is a good approach. I have one of the revelex chargers which i can hook up to my 12v flight box battery.
cheers
