I'm a Beliver.........Now

[n2ize]

This one was a Walkera 5#10. I've had it awhile, and decided to pull it out and fly it around outside. It's kind of a tween. A little big for inside, and a little small for outside. Yes, I've tried all the common stuff, and batteries were the first thing I tried as I have several extras. I think what happened, is when it hit the antenna, it damaged the inner rotor shaft. It's a coaxial unit, and the lower blades seem to spin out okay, but the upper seems very sluggish. At least it seems that way. I am trying another rotor shaft assembly to see what happens. It really acts like what you would expect if the motor gear and drive gear didn't have enough clearance, but that isn't the problem. I'll let you know what it turns out to be.

It sounds a lot like my old Esky V3 Coax (which is 3 years old, crashed a few times, and still flies). With the coax's any kind of hit generally strips the gears and bends the shafts. On mine it's the outer shaft that usually gets messed up (it figures, it's the more difficult one to replace). But sometimes the inner one will bend and , more often than not...BOTH!! I usually pull them out, take off the gears and roll them on a flat table. Any wobble and they are bent and need to be replaced. i've found even I slight bend can cause considerable power loss, short flight times, and reduced lift. This may sound dumb but of course make sure the right blades are on the right places. One time I accidentally put the top blades on the bottom and the bottom blades on top.

I don't fly the coax much these days and when i do its mostly indoors. Sometimes on a calm day I'll open the window (on the second floor) and starting from inside I'll fly it out the window and then back inside again. One time I flew it out the window, landed it on the patio, took off and brought it back in through the window. Another time a gust of wind blew it straight back in through the window and I crash landed it on a soft bed.

These days I mostly use the single rotor outdoors.
