How far back do I have to move the cg to get this thing to waterfall?  Flat spins inverted and upright are a blast.  For me knife edge requires some up elevator to keep it straight.  I have been reading about canopies falling off in flight.  I have not experienced this and think it has to do with the monocote that I ironed on over the holes it the firewall.  I also put a coat of epoxy on the firewall because I noticed small holes where the different pieces met.  I almost like this plane as much as my e-flite pitts model 12 that has a 25 fx on it.  With a little cg adjustment and a little more time flying it I'll have a new favorite.</p>
