JCB Mine weighed exactly 7lbs! I had a Saito 72 on her and had read in Hookedonrc's thread about lots of planes being tail heavy so not wanting to have to add any weight I put the sand paper to the tail section pretty good and all over too I guess and didn't have to add weight and flew great. That is until my switch or transmitter or whatever caused it to fly into the woods all of a sudden. Got 7 flights on it. got another kit upstairs and hope to start it soon. Can't decide if I want to build the bipe or an ercoupe next.
