I'm having big problems with the fairings, using the 2.5m interstage and 2.5m extended fairings when launching i get it up to about 10kms about 300m/s and start my gravity turn, as soon as i start to turn over the coupling points start wobbling around like crazy throwing it off course or breaking up all together! i have placed struts between the 2 stages using hex pieces and it does nothing?? please help i never had any trouble getting rockets up with the vanilla parts, also the 2.5 interstages wont decouple from the next stage without having a decoupler below the interstage itself?
