Bruce, My attempts to modify Bridi planes has met with limited sucess. The Utter Kaos I redesigned flew OK but not up to my expectations. A taller fuse is needed to make room for the large battery and pull-pull setup. I must be a masochist to keep experimenting as I am nearing demetia age. I keep trying though. I enjoyed the picture of my stretched Kaos in the SPA newsletter but alas the plane is no longer with us due to a crystal leaving the confines of the 649PCM receiver during a loop. Not a pretty sight!! A full large plastic trash bag went home with me.!! Back to my laboratory Igor!! .... Skip
