With the advent of the so called “400” sized heli, and the ensuing flood of available models , deciding which one to purchase can be a daunting task. Some of the questions that spring to mind are “Can it 3D?”, “Which motor and esc will work best?”, “Which servos should I use?”, and of course “Am I getting value for my money?”.

Well Heli-Max’s recently released Axe 400 certainly seems to fit the bill. The guys and gals at Heli-Max have put a lot of thought into the setup, and what you pull out of the box is a RTF 400 sized heli that is fully 3D capable, and comes with a 2.4GHz digital computer radio to guide it. Just add batteries and go.

Whats in the Box?

The Axe comes fully assembled and factory tested, as does the transmitter which is already programmed and ready to go. The Axe itself features 120 degree eCCPM, an easy access battery tray, a two piece frame, tail boom mounted rudder servo, a full set of bearings, 325mm wood blades, and a black anodized aluminum boom.

It has an impressive array of electronics. Starting with the receiver, the included Futaba R606FS FAAST is a lightweight 6 channel 2.4GHz receiver. The transmitter is the Futaba 6EX, a computer radio that can be used on up to six different models, including airplanes. It has all of the standard features you would expect from Futaba, including five point throttle and pitch curves for each flight mode, and swash adjustable function rate. The first thing I noticed when handling the transmitter was that it had a very familiar feel to it, and then I realized that the transmitter included with RealFlight G4 uses the same casing. Moving onto the servos, it comes with four Futaba S3114 high torque micro servos. The servos have 20.8 oz-in of torque and are perfect for this size heli. I have to say I was a little curious as to how well they were going to hold their center, but I was happy to see that they worked perfect. The included 425 outrunner motor has tons of power, and the electronic speed controller comes with the popular Deans Ultra connector already attached. The motor also features a built in fan to keep it cool. Mounted up on the back of the frame is the HM4000 heading lock gyro. The gyro features dual remote gain and mechanical gain adjustments.

First Impressions

Out of the box the Axe frame feels very rigid. The head, swash, and associated links appeared to have no slop at all and the pre printed canopy design is very eye catching. I was eager to fly the Axe right away, but first took the time to read through the instruction manual. And what an instruction manual it is! It contains instructions on what each of the controls does, how to track the blades, and basic controls of the transmitter. It also has one of the most comprehensive parts guide I have seen in a heli manual. As well as the usual exploded view diagrams, it also contains diagrams of each individual part with their associated part number and description. Also included are the measurements for each of the pushrods. All of this adds up to a very painless experience when having to identify parts when the inevitable “unplanned landing” occurs! There are also good descriptions of basic and advanced 3D maneuvers. One very interesting feature I found was that the transmitter comes with the idle up switch disabled. This means no worrying about accidentally hitting the idle up switch when you are starting out. Once you’ve mastered the basics you can then activate the idle up switch and unleash the Axe’s 3D potential. One of the things I like to do is go over all the links and pushrods and make sure everything is good and tight, and I add just a little thin c/a to the ball links where they are glued on the carbon tail rotor pushrod.

Flying

Flying the Axe is a lot of fun! It is very stable in a hover, and there are no pitching tendencies in fast forward flight. The 425 brushless motor provides a ton of power, and I was flip flopping it around in no time. Out of the box it was set up pretty good, and only required slight modification to fit my personal preferences. I used the recommended Electrifly 2200mah power series lipo, and could easily fly 5 minutes in idle up with some to spare. I wanted to see how the Axe performed on both ends of the spectrum, so I flew it around in normal mode to begin with. It performed well, and I had no problems flying figure eights, slow pirouettes etc. Flipping into idle up I was able to fly tic toc’s, rolls, pirouetting flips, and basic backward flying with ease. The tail held real well when I flipped to inverted and scooted along in a straight line tail first. Inverted hovering was also a no brainer as the Axe performed just as well whether right side up or inverted. The white main and tail blades, as well as the white fins, provided excellent visibility, and did I mention that the canopy was pretty sharp looking?

I was very impressed with the quality, and flyability (I just made up a new word!:D) of the new Axe. Heli-Max have put together a great little package that will take a beginner all the way to 3D without having to change anything except fresh battery packs. The Axe is also available as a receiver ready version, for those who don’t need another transmitter.

Nice! the Axe looks like a pretty groovy piece of RTF hardware.


...I'd put in a preference for no music during the flying though, can't hear if the motor is laboring with any of the maneuvers. Bogging being a pretty important issue for the aerobatic kiddies reading at home ;)

Rest assured I didn't encounter any motor bogging unless I over exerted the collective :D The motor is ballistic :cool:

I reset my radio and while trying to get everything back to manufacture specs Bad things happened. Does anybody know the stock configuration, or where to find it? I am new to Helis and don't need another mishap like the last one.

I got it, besides the gyro how do I adjust the swash? The blades are pushing down.

How do you mean pushing down? Are you talking about negative pitch? I set mine to have a linear pitch curve in normal mode and an s curve in idle up. If you need to adjust the pitch, do it on the N-PI screen for normal mode and the I-PI for the idle up mode. A pitch guage comes in real handy here so you can see where you are at.

I was wondering what you would recomend as far as tools. Is a swash plate level a must have? What are the must haves?

Check out GMoney's toolbox video, he shows the typical tools we all use. I would definately say a pitch guage, but you can get buy without a swash plate level.

As far as pitch range, mechanically you want to be able to get at least a linear curve of -10,0,+10. Once you have that set up you can dial in or out any pitch changes you need for each of your flight modes. For instance in normal mode you may change the pitch curve for normal mode to be something like -4,5,10 (low stick, mid stick, and high stick). Idle up definately requires the whole linear range of -10,0,10.

On the instructions it says max 45% on the P function in swsh. It looks like you have 75%. What exactly does that mean.
thank you

It basically limits the travel of the swash which affects pitch range on the main blades.
I increased mine to give me more pitch range, this more suited my style of flying.

Have you had any trouble with the gyro? Mine seems to have a mind of its own> It does not lock in, and I find my self trimming constantly on the gyro and the radio then it will lock in, by that time im 1/2 through my pack:blockhead:

If you lift up the corner edge of the Gyro label there is a small adjustment pot that lets you dial out any drift that you have. Try to start off with tiny adjustments to begin with, and go from there.

What do you have the gyro gain set to on the transmitter?

Hello all, I am an avid r/c airplane pilot and r/c heli fan. I started flying heli's back in 2001 and flew for a while and got real good with a Kyosho Concept 30 DX and a Hirobo Shuttle Plus (loops rolls flips etc....) well unfortunately I had to chose between buying transportation or keeping my heli's. :( Needless to say, I got out of the heli scene. anyway, I got myself an AXE 400 RTF for X-Mas thinking I'd be able to jump right back into it and well, the stock set up on my AXE 400 is a bit too touchy for me. So, I would like to start the learning phase over again and I was wondering if anyone here has any Futaba 8UA OR 6EX settings to tame it way down for a beginner as well as an idle up mode that will make it easier to transition back into stunt flying? I've also practiced with the AXE 400 on the sim but it's a lot more of a handful than the one on the sim.

Thanks in advance :)

I personally would start by lowering the EPA (End Point Adjustment) for the cyclic servos. See page 17 of the Futaba 6ex manual located here: http://manuals.hobbico.com/fut/6ex-2_4ghz-manual.pdf

This will cause your servos not travel as far, and thus will make the heli feel less sensitive.

You could also turn up the expo, so it makes it where you have to move the sticks around a lot to get a little movement from the heli.

Thanks for the replies. :) I'll try it and let everyone know how it worked.
