well guys I went for a flight today, I raised the swashplaye more, oiled the main shaft and swashplate, made sure the antenna on the radio was fully extended, put fresh batteries in the radio, and let the antenna on the helicopter dangle down alittle, tryed all these things and im still get what seems to me a glitch, still shooting up and then suddenly down, I flew two packs through it and had it happen about 4 times, I mean its managable when it happens 4 feet off the ground but I couldnt imagion having it happen 30 or 30 feet in the air, im not sure what is happening
