[NSRCA-discussion] 8- cells?

[J N Hiller]

Ron I'm thinking I need to plan the KV-RPM-Pitch relationship at 3.3 v/c. Is
this realistic?

I think the biggest problem for 8S battery fliers will be vertical
performance, especially late in the flight.

Keith, I think there was a recent thread on RCU discussing a 2M model with
8S.

For same relative performance (minus weight impact) you will need to
increase the amps by about 20-25% to get the same watts.  You would either
need a motor with a higher kV or a higher pitched prop or both to get
similar watts.

Is anyone trying 8 cells this year in their 2 meter plane?
