Yes AEAJR the 7 cell pack from the Aerobird fits great in the Electrajet. I flew one today
I've been reading the threads for a month, my first post
I started my first venture into r/c on the Aerobird 8 weeks ago, just got the Electrajet yesterday, it isn't new and has much tape and glue
flew it today for the first time with the Aerobird 7 cell X Pack and it works great, very touchy after the Aerobird though, tendency to over control. I also have a Thunder Tiger Sparky that also works on the same 7 cell pack. good luck with the Electrajet and have your 5 minute foam glue ready
