Hi all. picked up a digital scale over weekend. weighed all my planes and my new heli. my parkflyer edge 540 weighs 22.7 ounces with thunder power 2100mah lipo/e-flite 400 inrunner with heatsink and gearbox and a jr reciever. what this means is if you do modification and use the stock 1800 lipo differance in weight will be very minor but highly out weighed by performance increase. still waiting on buddy to get his new fuselage.. he bought one of my 400 inrunners and we'll be doing mod on his edge also pretty soon. i should have more pics and possibly video how to of conversion. unfortunatley weathers been bad out here for flying and probally wont have any motor performance video till spring.
