Yeah, unfortunately a bit more than I think is worth.
Upon buying my very own (third hand) Lightwing, complete with it's singular approval to run a Bolly prop, and maybe a few other non approved mods, it was suggested to me that for a small fee, I could have the pilot notes, and thus certification and weights, updated to the LSA class for better utilisation.
When the aircraft got damaged by a student, and I started the rebuild, it became apparent that their were some vagaries to be dealt with.......
I would still like to point out that I feel the Lightwing is still one of the best trainers we've ever had, having only one(questionable) fatality in around thirty years of operation.
Many people have had their little inputs to improving the Lightwing along the way, not least of which was usually replacing Howard's 'Piece of Wood', with a decent propellor (Sweetapple, GSC, Brolga, Warp, Bolly?), or other little mods.
Now it's hard to know just where the Lightwing sits, and as such we are in fear of losing a great plane for the sake of pretending to be GA certified.
YES, but it' mine, and you can't have it.
I'm talking about my Murphy Renegade project.....

There is a Murphy Rebel flying around with an R2800 up front, AND, I know where there are 2 Rebels in various states of disrepair, that could be 'moved on' to make room for other projects........
