Yeah, but 4 pounds seems awfully high. My motor is definitely lighter then a glow motor so it doesnt make any sense why my plane weighs that much. I did not add any dead weight. I placed 2 or 3 rx type batteries right up behind the motor for balance reasons(2 x 2700mah 6v rx batteries for the plane and then one 1500mah 6v battery to power the JR matchbox controlled 4 flap servos. I did this to keep a massive load of current from going through the receiver itself if it had to power all 12 digital servos in the plane.
Anyhow....Im stumped why it weighs that much even for an electric. However, a buddies electric H9 80" P-51 weighs 20 pounds so i guess its about right. Man, I better be careful about making steep banking turns LOL...just like the real plane...flew heavy...but in the right hands could actually outturn a P-51. But, 9 times out of 10, the ME-109 pilot wasnt skilled enough to do it....hence why the P-51 was normally attributed as being a better aircraft(I dont really agree with that technically...but it was when an inexperienced pilot is in the ME-109)
