Jose brings up a point Ihave preached to students over the years, build a kit or two and you will know how to repair an ARF. Ihave one old student that has crashed and broken his H-9 Pulse three times and it's still flying and you would really have to look close to see it was evenr broken.
My old Kaos was cut by Joe Bridi about 20 years ago, it's on the fourth cover job and Ihave broken the fuse in half twice, most people don't know it was ever crashed. Ibroke it about two months ago and everyone thought it was a trash can plane, it was back in the air in a week with very little signs of any repairs.
ARFs are fast to get in the air but you should learn to do your own repairs. You can always find parts like canopy's and cowls from other ARFs that you can make fit even if your plane is no longer made. An Extra is an Extra, all you really need to know is the size of the plane so you can match parts with from another manufacture.
