I will stick with my new rcv .58 this is a fun fly plane something to relax with when i dont feel like flying my Radiocraft extra 330 35% with Brison 6.4 up front. Anyway does the plane fly unstable at that cg how sensitive is elevator at that cg I was thinking of around 4 to 4 1/2 inches back instead of what they recommend . Thanks for the info any way . Bruce Oh by the way the guys on the forum say it is real tail heavy at the recommended cg and have to add a lot of lead up front with a 60 or 70 four stroke. so if i could move cg back a ways it would cout down on the amount of extra weight i will have to put up front any comments ???
