The Walkera 4#3A


This was the second Helicopter that I ever purchased except mine was the 72mhz version since the 2.4Ghz wasn’t out yet.  I was really good with the little mosquito and had tried the Falcon 40. With not a whole lot of success and thought, well I will go back to something smaller.  This looked good and stable in the videos and seemed to be ‘the thing’ that I could practice in the living room since the falcon 40 really isn’t a ‘living room  helicopter’.  The description said it was for intermediate pilots but since I had some months flying a co-axial and about a month or so on the Falcon 40 I thought ‘what the heck it looks like fun’.  I knew that there would be some learning curve here but I was really unprepared for the difficulty of flying this little guy.  I got this at a time before the mCX or mSR had been released and it was quite a handful.  Taking off without crashing and just flying for more than a minute at a time was really hard with the included controller.  I think they hadn’t heard of ‘expo’ on the transmitter at this point.  It was really touchy and even though I learned a lot from flying it I did crash almost all the time.  True to its nature this little heli held up well and usually the worst I had to fix on it was re-snapping on a ball-link.  I hit walls, furniture, couches, chairs and of course the ground.  All this just trying to hover the thing.  Now I think I would handle one of these better today and in fact when I destroyed my first one (finally) I bought another and upgraded it to the metal head parts! Still it is a micro handful and I don’t recommend this to someone who doesn’t have quite a bit of experience.  One of the drawbacks of this Ready-To-Fly bird is that it is a complete system and you can’t modify the settings on the controller that much.  They have now come out with a 2.4 Ghz version which should help the semi-wonky electronics (there were the rare random times where it lost the connection with my 72mhz version)  and the ‘B’ version comes with the all-metal head which I highly recommend. And also there is a version with a programmable transmitter that would be handy to have .

One of the things I really loved about this was the way it sounded it was just so cool sounding.  I had to replace blades a couple of times, the tail rotor motor once and tail blades twice.  All in all a very sturdy machine but just very touchy and if you aren’t smooth on the sticks then it can be a handful.  It is pretty fast and light. Here are some pics and the specs from the Walkera website.   I got both of mine from  with no troubles

This little heli uses 2 servos on the swashplate that are 90 degrees apart.  The battery tray is a bit of a tight fit but it is situated in such a way that you really don’t have to remove the canopy to install the battery.  The transmitter uses 4 AA batteries.  When you get one of these it is truly ready to fly 100% assembled.   Just pop in the batteries in the Tx (transmitter) ,charge the heli battery and you are ready to go!.   I would recommend that you pop in and see the Helifreak post : Walkera 4#3 Tips and Tricks  As usual the guys over there have a world of knowledge that I have drawn from over and over.  Alas I didn’t know of them until after I got into helis for a while.

I got mine from Xheli, but the following two places are good as well.
