HAS ANYONE HAD LANDING GEAR FAILURES ON THE CENTENNIAL T-28? i HAVE HAD 6 IN A ROW. ALL FAILED IN THE DOWN POSITION. 1ST FLIGHT RIGHT WOULDN'T GO UP. THEY SENT ME A PAIR OF NEW ONES. REPLACED RIGHT ONE AND NEXT FLIGHT LEFT FAILED. REPLACED IT AND THEN IT FAILED ON FIRST FLIGHT, SAME STORY WITH RIGHT ONE NEXT FLIGHT--SO FAR THEY HAVE SENT ME TWO SETS AND I HAVE 6 GEAR FAILURES ALL IN THE DOWN POSITION. LAST NIGHT I OPENED UP THE 2 MAINS AND CLEANED THE LIMIT SWITCHES WITH CONTACT CLEANER AND ALL THREE GEARS WORKED THROUGH 12 CYCLES. THIS MORNING I TURNED IT ON PRIOR TO FLYING AND ONLY 1 MAIN GEAR RETRACTED, LOWERED THEM AND TRIED AGAIN AND ALL THREE GEAR ARE STUCK IN DOWN POSITION. I UNPLUGGED EACH AND WENT DIRECT TO RECEIVER AND ALL 3 LOCKED IN DOWN. REVERSED THE FLAP AND GEAR WIRES AND STILL NO GEAR. REMOVED ORANGE RECEIVER AND INSTALLED BRAND NEW SPEKTRUM AND SAME EXACT PROBLEM, NO GEAR AT ALL AND LOCKED IN DOWN HK SAYS THIS IS A 'RARE' INSTANCE AND HUNDREDS OR THOUSANDS IN USE WITH NO PROBLEMS. I JUST CANNOT BELIEVE THAT. IF MY LUCK WAS THAT BAD I WOULD HAVE BEEN STRUCK BY LIGHTNING BY NOW---AL KRAMER
