It's Iowa, the wind is rarely below 15mph. Yesterday was 22mph. Went out today with the tank fixed, solved my problem and flew great.

There is another nice thing about the gasser... you don't have to worry about getting oil on your car seat.

Put the V-bar on it today. Converting the Tempest head is dead simple, just pull off all the flybar stuff and washout, and use one of the long balls from the mixer arms to get the links the right distance out on the grips. I used the Mikado swash driver from my 600n. From there, it's just electronics, all easy stuff. Lost just a little over 1/4 of a pound too.

Swapped out my throttle servo to a Futaba 3151, which I had great luck with on my Predator. My last flight with the Hitec the servo died in the air at around 1000rpm headspeed. I set it down on the runway with a bit of negative and let it run itself out of fuel. Luckily, the vibration closed the throttle after about 10 minutes, otherwise I'd have been waiting for hours. I doubled up the throttle servo mount by JB welding 2 of the carbon plates together to give it some stiffness. The flimsyness of the stock arrangement couldn't have helped servo life.

I have not flew anything flybarless but I do understand all of the benefits of getting rid of the flybar. Thats just downright sexy Eury please let us know after you have flown it if the power difference is noticeable from losing the flybar.

Will do, the weather sucks today, so no chance to fly it (and I was working on the Miata), but I can tell you that the 600N I took the Vbar off of had a pretty big power increase when I lost the flybar.

I am afraid that I am going to have to require a video of this.

It's only about $3k away for you to build one and make a video of it.

Interesting

I would like to hear how you like it. I've flown other people's flybarless systems one on a revolution 90 size ship and the other on a lepton. Basically on the revolution I never got the feel that the ship was quite locked in. As if there was a gallon of water on-board and it would slosh around and you would be fighting it trying to level the bird. People always say its in the setup, and it could be, but it seems not so simple and you need a laptop at the field to fly and tweak and fly and tweak and fly **N (to the power N). If you thought tweaking needles was a chore, this seemed like a bigger one.

However, I flew the lepton guy's system and it seemed better, though it had that odd feeling of you having to level the machine all the time. Its heading hold in all axis and when you go to land you have to fiddle around with the cyclic to keep the machine level on the ground as you're spooling down.

I didn't get that warm fuzzy feeling I get from a $10 flybar so I wasn't go gung ho and trying it myself.

The bottom line is you will probably get used to whatever feeling it gives and adapt to the flying style it needs to keep the bird in the air. Over time it will feel good I'm sure.

I really find it hard to believe that people want to watch videos of me flying. Hell, even I get bored watching me fly.

The ones you flew weren't setup right, Raja. Fighting to keep it level? Set up right, you can take your hands off the controls and it'll sit level until it runs out of fuel or hits something. I can literally take off in a 25mph wind, and take my hands off the sticks and it'll sit level as it drifts with the wind. In forward flight (upright, inverted, whatever) get it going in level flight and it'll stay on track without messing with it. The great thing is, it's not only stable like that, but it's faster and more responsive than any flybarred heli I've flown. Takeoff and landing is no different than any normal heli. I've let a number of guys fly my 600N with the Vbar, and I don't have to give them any special instructions, just hand them the transmitter, it flies just like any good heli, except more stable while also being more powerful and responsive.

And you don't have to bring a computer with you forever. Setting mine up on the 600N (first flybarless I've ever set up, so no experience at all), I brought my computer to the field twice and tweaked settings, I maybe hooked it up 5 times before it was dialed in, then the computer never came to the field again. It's no different than settign up any new heli, I bring more tools those first couple trips, then leave them at home after that.

It's not difficult to setup as long as you are capable of reading instructions, but reading these forums, it's pretty obvious that most people have never opened a manual.

Not boring at all. I had a local pilot film me fly and I was somewhat impressed that I looked better on video than live...

Got to fly it today, worked fine, the Vbar had no problem with the vibes of a gasser. Spent a few minutes tweaking it with the computer and got it flying very well. I don't know if I'm going to keep it on or not, for a couple of reasons.

The big one is that I'll have to buy a new headblock for my 600N if I do, or just have 1 flyable heli until I can afford another V-bar. Also, the power increase isn't as big on this as it was on my 600N. The stability is awesome, it stays put perfectly in any attitude I put it in, and the cyclics are fast, but it's not as big an increase as it was on my 600N, probably because this flew great before, where a 600N really doesn't fly very well stock. If I had 2 flybarless systems, it'd be a no brainer, I'd keep it V-bar, but with only one, I may end up putting it back the way it was.

Thnks for the update Nick. I have my V-Bar unit half way out of my logo already. I may still try it out to see for myself. I think the biggest advantage would be faster roll and pitch changes. A bit more power would not hurt either...

I'm going to play with it a bit more before I pull it out. I just wasn't blown away like I was with the 600N.

This is what I like about flybarless the reports of being able to have super sick cyclic but still be stable. This is very good info thank you Eury. For example I loved the locked in stable take your hands off and smoke a cigarette then come back stability of my Pantera 50 but as I modified the rotorhead to get almost 10deg of cyclic that stability lessened its till not bad but alot worse then when it was in its box stock config.

Again thanks for the info it is also good to know that v-bar will handle the vibrations of a gasser. Power gain aside large or small being able to have your cake and eat it too stability and rocket fast cyclics is too tempting to keep me away.

Its not a maneuver until your looking down on it. ~Jason Krause~ Phoenix FF 08

I got the V-bar pretty well tuned in today. Made 3 flights with adjustments in between, it's definitely picked up some power, and it now has that uncanny V-bar stability along with lightning fast cyclics. In fact, the cyclics are too fast at this point, I need to make some changes. The aileron axis is good with a roll taking about half a second, but the elevator is too fast right now, it's probably about 30% faster than the aileron.

But, I do have a decent baseline setup right now, after a flight or 2 tomorrow, it should be locked in. Right now it'll hover hands off and just drift with the wind, and in forward flight (upright or inverted) it'll go hands off from horizon to horizon. It's got more power, I'd guess on the order of 15% more than with the flybar, and agility is way up, as well as hang time in autos.
