I think that is worth make a several miles trip to get assistance for the first flight and trimming of
your roo... a experienced jet guy talking with you while you fly can make a lot of difference! also some G2 flight simulator (or the like) helps,, if you can fly and land decently a F-16 or a F-4 several
times without runouts of the landing strip can help... you could also simulate the high trustline of the roo in this models just to see how the plane reacts in the pitch trimming while you throttle up the turbine in different flight speeds...
