What are some advantages of going flybarless? Now that the Chinese have caught on there are some cheap fbl systems out there that are cheaper than a gyro. For a sport flyer that only flies a couple times a week, would it be a worthwhile upgrade? Also how well does the 3 axis gyro work in fbl systems?

FBL does for the cyclic what a HH gyro does for the tail.
Much more stable. Lower parts count. Easier to set up mechanically. Less spinning mass=less power consumption.

The 3 axis gyro makes the pitch, yaw and roll axis servos return the heli to neutral when the heli moves off center in any direction except vertical.

It'll make the heli more stable. That should help some.

Ilk give it a go as funds permit. That's saying something since I used to say I wouldn't

Knowing what I know now, and if I had it to do all over again, I wouldn't change if all I got to do was fly once in a while.... but that's just me. Don't get me wrong... it was nice. But for how I fly, it just wasn't worth the investment. The Chinese systems like this one are great buys: www.besthobbysite.com/shop/product_info.php?products_id=15031However... read some of the other forums threads about set up. When i first set up the my 3G a long time ago... it was expensive, but easy. Align made sure that I had all I needed to set it up (Burt Kammerer videos). There's more to consider than cost of the initial purchase. What kind of support are you going to get? i.e. Who are you going to call when the chenglish programming manual gets a little dicey? What kind of FBL Head are you looking at? Are your servos up to the task? Sometimes cheap works out great... sometimes it doesn't.

Thanks everyone for there input, I greatly appreciate it. I guess the main reason that Im asking about going flybarless is that, Ive been flying helicopters for almost 3 years now I can fly tail in, side in and FFF. But I have yet to be able to fly nose in. The main reason that I havent been able to learn nose in is that Im always to worried about crashing and having to spend a lot of money after a crash.
Right now Im looking for a way to be able to speed up the learning curve. I dont want to spend a ton of money though being that I only fly once in a while and because in less than a year Im going to be off to college and will probably need all the money I can get.
I have looked at the Blade Mcp, from what I hear its pretty durable but alot of people have had problems with parts failure like the 3 in 1 and motors. People also say its underpowered.

I think FBL is the coming thing and will get cheaper just like spektrum clone RX's. There is no reason in this day and age of electronics that a helicopter cannot be self-stabilizing at a reasonable price. We have cell phones we throw away every year that have more computing power than all of the Apollo missions put together and we put a man on the moon with the junk electronics in 69.. Also why would you want to swing all that mechanical crap around anyway it just rob's HP and adds weight.. my 2 cents.. Ray

i dont think a fbl system will help with nose in, if thats the main reason its being considerd id think it momey wasted.
i have a used real flight g4 sim. in my open its the best money ive spent in this hobby.

I agree with Ray, and having converted a 1#A from Hiller to flybarless, the overall control feel is quite different. You won't miss the wandering here and over there deal. That's gone, it's replaced with a more crisp centering for clean hovering. Too, the "drag" time between command and result are sharper than ever. Hiller systems were always hard to learn because of learning the command-wait-action-oops-oh-stuff-command...thing. It's gone. No, it's not idiot proof, but finding a spot for a clean hover? Loads easier. But, no, it will not make nose-in any easier. Sim time or a coax, so you can afford to make boo-boos and not weep. Too, as suggested: Meaner servos are indicated. RTF seems to think anything bigger than a 300-370 size and you MUST own metal gear servos or watch a mess to take place....like I did? So, 450, 500, yas, MG servos are indicated. And if he's correct, and this is the deal now, we'd best get used to it and quickly, as the paddles will go the way of disco.....

The FLYBARLESS is the hottest thing going. You will know this after flying the traditional FLYBAR CP helicopters. What a difference and the repair time is a lot less with less spare parts. When we originally did the FLYBARLESS Conversion, we couldn't believe the flying difference. The control is much better due to the 3-Axis Gyro technology. Below is our video of converting this bell-hiller flybar rotor head into a flybarless. The test flight is also using an 11.1v LIPO instaed of the stock 7.4v LIPO.

Thanks again guys. What do you guys think about the Blade Mcp? People on the Groups seem to like it. They say its really durable, so crash damage would be minimum and I could also fly it in my house regardless of the weather. I just got a $30 off coupon from my local Hobbytown.
Also if my local Hobbytown had one on display do you guys think they would let me try flying one before I bought it?

The guy that runs hobbytown here would bite your head off if you asked him for the time of day. Odds are, your guy is probably nicer. No harm in asking to fly it.
At any rate, the mcpX flies good. You'll like it.

I just got back from flying the Exi 450, I dont think I need to go flybarless, yet anyway, I just need more practice. I think if I get the Mcpx I would be able to practice even more while the weather is bad. I just need to find more time to fly and have the weather cooperate.
