You know i started off with a TT trainer that went thru almost 10 crashes 3 major ones while breaking the firewall or loosening it were almost weekly affair tilll i got my landing right
So anyway to fix the plywood firewall now and again I had to cut off almost an inch to 1.5" from the design length (alas she is no more ... elevator clevis failure !)
but the plane was so damn good it would fly w/o any noticable CG shift !
Well thats that ! Cheers
