Flt the heck out of it.
THe plane is a good flyer...the YS 91 is a good power plant and at your elevation at 8lbs it will be more than enough power....In fact it might be over powered.
Just spend some time with the plane and learn how to make it do things right. The newer airplane designs (wide Body) designs have evolved from the the F3A sequences. These sequences have rolling loops, snap and roll combinations and require tons of power. The current Masters and the new masters sequences proposed for 2005 all are without these requirements. Soooo flying Intermediate or Advanced is cake for a plane like this. Its all the guys on the sticks. Make sure your equipment is in good working order and keep up on maintaining your servos and the rest of the plane. It should last a long long time. I have a Dr J 2 that was originally flown in 1995 and it still flies great. Right now I think it has over 3000 flights on it.
I haven't flown it in a couple years but I would bet just sitting in the shop it will perform just like always....Maybe some new batteries.....
