I am trying to fix up a very old Piper J3 given to my son by a members of my local flying club. It is at least 20 years old and is a 71" wingspan balsa plane that may well have been a scratch build. It had a very old electric motor and esc that I could not get to work. The nose/cowling was carved from a solid piece of balsa and was set up for a off-set-geared, brushed motor. It has an 11x7 wooden prop.
I have decided on an 80 Amp Esc with a Turnigy Aerodrive SK3 - 4250-500KV Brushless Outrunner Motor. I decided on the motor based on a weight-to-power ratio chart I found online.
Can anyone tell me if that seems to be about the correct size/power motor for this plane?
The old motor said "Turbo '10' Plus" and "War Emergency Power Series" on the can. It was made by Model Electronics, Inc. of Seattle, Washington.
I plan to use a 6s battery with it.
Thanks for any help,
Scott "Kobur" Stevens
