I've only had my P4 a couple weeks and only flown it about 5 times (weather not cooperating). I had a P3A for a year prior to getting the P4 and flew it dozens and dozens of times maybe 75 flights. I made several bonehead moves early on and paid a financial price to learn those lessons. In the end though, I felt very comfortable and secure flying the P3 and it was actually very reliable and trustworthy once I got the hang of it. I also became quite familiar with it with all my senses.
Now I have the P4 and am doing smaller flights reaching out further little by little until I gain that same confidence. I know that the P4 uses slightly larger motors than the P3 and I am now wondering if they produce a sound that my P3 didn't. I hear a distinct high pitch whine that is RPM sensitive above and beyond the normal whooshing sounds of the prop wash. If I hover the craft at eye level or just above me I hear it plain as day. If I accelerate the craft straight up I can hear the note of the whine increase in pitch until the craft gets out of ear shot. As I bring it down I can hear the whine grow louder as it gets closer to me. So my question is .... does anyone else hear this additional sound, or is it just me. Is it possible that there's one motor with a slightly tighter tolerance somewhere in the assembly that will break in and decrease as it gets some hours on it ? Or is it a portent of things to come (motor failure) ? Or do you think I should take advantage of a Feb 5th return date option ?
