RE: AMT ECU Battery for Pegasus
If its vintage 1998 then it's,likely version 1 and if you are gong to run it manually you can run any 11.0v pack to power the ecu. If you are going to use an auto start box, talk to CraigG.
I have Flown over 6 flights before recharging and will likely only use only 400-600 mah on a 2200 mah 11.0 v lipo
Good luck with it, they are rock solid motors just a lil heavier than other stuff on the market.
