Paul,
I agree, not bad especialy when my last JFM Hawk (yellow, ex Simon Peckham) weighed 14lbs dry with an SPS 54. That flew great but would G-flick given too much elevator. I think this will come out at least 2lbs lighter than that one if I use a P60 and as you say save another pound if I use my Wren 44. I now have a set of Robart retracts to fit. Trial fitted then in the mounts and no problems with width or depth.
