Hi MAC_2111, the Aerobird 7 cell just fits right in the Electrajet with no mods, although the guy who owned the electrajet before me had broken the nose off several times in several places and has been glued a lot.
not sure on the flying time it was very windy yesterday, I only had 2 short flight of about 2 mins each as it was my first time with the Electrajet, the guy that owned it before me was there yesterday, he has a 10 cell and an 8 cell, hes had them both in the electrojet, when he saw it he said it was going as well if not better with the 7 cell Aerojet batteries in. If I new how to post a picture I would
I'm using a JR Quattro as a radio.
cheers
