First Flight # 719

Post by Rusty & Patti » Sun Feb 19, 2012 8:35 pm

Murphy Rebel N547A SER# 719 took to the air for first time . Liftoff at about 600 ft on the grass, I held it down a little for the airspeed to come alive,more on that later. Aircraft seems to levitate rather than rotate. Clime rate seems normal for this power ,LYC O-235 and wing loading. Controls are VERY light with little feedback but are not twitchy and no tendency to over control. Very stable at cruise but seems to have neutral stability on this short flight. All engine ops normal ranges. All pitot and static instruments seem to wander quit a bit and could not be trusted so more testing, and experimenting will be necessary. Landing was accomplished with no problems at KPLR after 33min of flight with use of lift reserve indicator for airspeed control . Many THANKS to ALL my aviation Buddies without which this project would not have been so much fun. Many THANKS to the frequent posters of REBEL BUILDERS whose experience kept the project rolling. Special thanks to Cris who got this ad
venture started.

Second and third flights not nearly so exicing. GREAT plane, FUN to fly. Static system problem improved by sealing original static ports and relocating 1/16th in. holes 2 in. from tip of STD MAM probe. Performance tests ongoing, so far follow MAM data.

Keep on pulling those rivets Thanks
