Our Bonanza is a BE-35G, 1956 model with 3879 hours on it. We have owned it about 4 years and fly about 350-400 hours a year. We have replaced the interior with complete new leather seats, side panels and headliner, as well as plenty of sound proofing. It has an older E-225 engine which we will be replacing with a BDS IO-520. I am presentl wiring up a new center stack pannel for it. As it is now, it curises about 150 knots; and is truly our "Magic Carpet."
