I'm very interested to see how the latest V-bar suits you
You and I both.

I crashed this bird once again in Orlando, pretty minor and parts are on the way. I'm hoping to have the V-BAR on by the first week of the new year.

You might want to wait until the V-Bar 5.1 firmware is released in the next few weeks. Not only will it include the best governor on the market for both nitro AND electric, but it will include a vastly improved swash algorithm. You will be amazed! Beast who/what!

Got 3 flights on the Microbeast on the newly rebuilt(once again) X5. First and subsequent flights went great. FWIW, the system continues to operate as it had been despite the 2 crashes, no issues incurred.

I'm going to install F/W 2.0 tonight, and fly it again tomorrow. Will report back tomorrow night. If all goes well tomorrow, I should have the V-BAR installed and ready for testing next weekend.

HAPPY NEW YEAR!

I finally updated the Microbeast to F/W 2.0 last night. The update procedure was very easy(and free). Updating the system requires the setup to be redone. The setup and parameter menus are different from the last F/W version, there are a few more options. Without going into much detail, I tried to mimic my original setup as closely as possible so as to see if there were any noticeable changes in flight performance. The 3 pots were also left untouched.

On the first take off, as soon as the machine became airborne there was a VERY rapid oscillation on the aileron axis. I needed to adjust Pot 1(cyclic gain) down about 60 degrees, from 9 O'clock to 7 O'clock, to stop the oscillation. I did my normal routine and the first thing that I noticed was that the rudder seemed to be more sensitive to aggressive inputs. I had increased the tail dynamic setting(Pot 3) with the last F/W, so I ended up setting it back to the default 9 O'clock position and it felt more comfortable.

I was able to put 4 flights in total with the 2.0 F/W and I have to say that the update had a subtle, but positive, impact on flight performance. The tail performance seemed to have improved a bit on the starts/stops(more precise) and the collective felt more "active" around center stick. Other than that the Microbeast performed fantastic, as it had been.

Now for the turning point in this thread.

I feel that I've had enough time on the Microbeast to know exactly how it performs, so this afternoon I finally got the courage to yank it off of the X5 and install the V-Bar. I upgraded to the 5.0 Pro software right off the bat and got one test flight in this evening. Unfortunately, I'm going to have to save my initial thoughts for tomorrow evening. It's late and I have to get up early... Here are some pics of my setup:

Al, I believe your sensor lead is strapped in too tight, you might consider giving it a bit of slack

FIRST V-BAR 5.0 REPORT!
Thank you, melinau

hookmaker, the strap only serves to isolate the first inch or so of wire coming out of the sensor, TO the sensor. Without it, I suspect that the additional unsupported length would increase the chance of the wire resonating. The wire is under no tension, and is fixed to the frame about ~3.5cm from the strap(Mikado recommends 2cm). To be honest, the included mounting tape is so thin, I doubt that it would make much difference anyways.

I put 3 more flights on the V-Bar after lunch today. Before I get into the flight characteristics, I'm going to touch base on the initial setup.

My only prior experience setting up a V-Bar was with 4.0. Although 5.0 is not difficult, I think that it would be easier if Mikado just got rid of the included paper "Quick Start Guide" altogether. I found that the Quick Start Guide becomes rather redundant when read along with the setup wizard. The directions on the wizard itself, although acceptable, were not nearly as clear and as thoroughly written as that for the Microbeast. It was daunting having to upgrade my software to 5.0 Pro($45), but the procedure is actually pretty straight forward if you follow the video on the V-Stabi site.

I left most of the default values alone except for expo settings in the expert menus for the main and tail rotor, which I changed to 0%. I also increased the yaw rate setting to 110% and enabled the main and tail rotor optimizers.

Initial testing:

My first flight with the V-Bar took place last night in a dimly lit area. I had programmed 20% and 10% expo in my radio(same as the Microbeast) for cyclic and rudder respectively. Take off was very easy and my X5 lifted off into an EXCEPTIONALLY stable hover, no trim. Just hovering, compared to the Microbeast I found that the cyclic felt a bit more precise around center. The V-Bar seems to "settle" better in a hover. Pirouette rate felt good and like the Microbeast, the disk will hold its attitude perfectly while pirouetting. One thing that REALLY impressed me was how well the V-Bar was able to perform "cracking" movements. Most FBL systems I've flown don't track these type of rapid and aggressive cyclic inputs as well as a flybarred model, and I was pleasantly surprised to see that this system could. I did a few flips and rolls, though, not really enough to get a good feel for it.

On the second flight, I was able to do my regular routine. Like JayL said, the V-Bar flies VERY smooth during traveling flight. The cyclic response is nice and consistent, although I felt that the elevator had a bit of lag, perhaps slightly more so than the Microbeast. That said, the V-Bar was still quite predictable. During pirouetting maneuvers, the piro optimization on the V-Bar seems to work better than that on the Microbeast. On the Microbeast, if I were to be overly aggressive with my cyclic inputs while doing, say, a pirouetting tic-toc, the cyclic would lag slightly behind my inputs and my timing would be off a smidge. On the V-Bar, cyclic phasing feels very "tight" during pirouetting maneuvers, encroaching on the performance of a flybarred model.

On the third and fourth flights, I played around with my radio's dual rates and expo, trying to get the cyclic and rudder tweaked to my liking. I've always said that I liked the way the V-Bar's tail gyro performed, and I want point out that the Microbeast's tail performs VERY similarly. The V-Bar's tail feels a little more locked in.

Overall my initial thoughts on the way the V-Bar flies compared to the Microbeast is that it feels more "synthetic", but, it responds quite consistently during most aspects of flight. Just to note, I have not yet made any subsequent changes to the settings in the software, but the V-Bar is already performing extremely well.

I'll try to get a video this weekend.

Outstanding,
Glad to hear you have found the 5.0 to your liking. I was very interested to see how you felt about the system, you are aware of my skills with a heli and realize that most any current FBL offering will be more than adequate for me. I'm particularly interested in the V-bar system as I have been very impressed with the performance I have witnessed in other local fliyers helis using this system. Even more so now with the impending release of a governed upgrade for the nitro crowd.

Allan, all I can say is wait till you get the V-Bar 5.1. It will rock your world! I flew 8 flights yesterday with it (actually Beta V5.020). The difference between 5.0 and 5.1 is amazing. Cyclic response is quicker (no lag) and at the same time smoother than 5.0. No more "synthetic feel".

The only thing that i really dont like about the vbar is having to pay for an update. Their is a slight delay in the elevator but both systems fly very similar with slight differences. I would buy another vbar for sure but would also buy another mb without question.

Governor and the new tweaks and forward updates are free for 5.0 Pro owners, and it was worth it, a huge step over 4.0. As stated the 5.1 and onward is another BIG difference and improvements. Look forward to further testing results here....Once upon a time there were Nitros, flybars and frequency pins...
