I see them for sale used for under $100. It would be a less expensive way to get into FBL. But are they that bad? I want to go FBL on a 450. Thanks!

No, they are not bad for what they are. Great product that requires a bit of knowledge to get working properly. Every size heli has a different setup with the 3G, so you have to be very careful who you take advice from. You also have to be aware of what a particular setup is intended for, ie., hard 3D or FAI. There is a big difference in the gains and other settings between flight styles. After having setup two of my own and a few for friends, there is not a one setting that fits all(people). The stock settings a great place to start for a beginner. Very high gains, and a very locked in helicopter. If you have any issues flying mild 3D, it's either due to setup or vibrations.

The biggest issue with the 3G unit as far as us hard 3D guys are concerned is the lack of hard/quick tail authority. If you're coming from something like a Spartan DS760 or Futaba 701 you will be pretty disappointed.

it is decent for novice pilots but it can't even compare to a V-bar or Total-g.

Ok how do you guys think the new align 3GX will compare to the top end systems, and any idea when it will be released ? I wanted to go for
a futaba 750, then i read align will be bringing out the new 3GX,

(going futaba is going to cost for i have jr at moment hence i'm looking at the 3gx) and it is the latest system that will go into production. i just want to fly with my pcm radio, no converters or anything else, i'd like to keep it simple, yet i want a performance system.

For relatively basic stuff they are fine and a good intro into the world of FBL, the head will happily work with other FBL systems on the market too (which you would need to buy what ever you do). Setup is easy (but that's it).

The down side is it suffers from feedback loops and vibration (mainly seen when flying hard 3D), also the sensor plug seems a bit dodgy. The setup when compared to other leading systems is average IMHO. There are other things I could list but it's outside the scope of what you are asking really.

I would say if you are a beginner and want to try FBL it's a good starting point based on price. I would recommend the BeastX system also for a beginner but given you will also need a FBL head based on price alone the 3G might be the better option initially. (Note that most people are selling the 3G controllers without the head)

Like I said, becareful who you take advice from. I'll also add at this point in the thread that HF is far more useful if and when you get a 3G. Instead of trying a hardcore 3D flight on stock settings, getting terrible results, giving up and calling it crap, the HF crowd at least attempted to play with the settings. With great results I might add.

Anyone with a bit of sense knows a heli will never fly perfect stock setup regardless of what it is you are actually trying to setting up, heli's are complex.

It's not really too bad, it's just not up to par with the others. Align has figured it out and the are now working on a new 3G called 3GX. The problem with FBL systems is not the hardware but it's the software, that is why you should go with a system which has been proven for many years.

Not bad at all. I have 5 of them from a Trex 500 to a Trex 700N and everything in between. New units now come with mods, so no fiddling. Load the Leon Luke settings, set it up and go fly. I run v2.1 and never had tail kicks people talk about. Even while doing fast tail in inverted hurricanes.

If you've never flown a FBL system you'll be happy with the performance. Later if you try a VBAR the performance difference will be obvious.

had 3 align 3g's tried v1 v2 and v2.1

from v1 to v2 was a nice diff on piro consistency but that was about it. i still had random tail kicks, tons of cyclic bobble.

then i did the leon luke mod and they got a little better.

then i spent 4 months worth of days at the field tinkering with settings only to never get it exactly the way i want.

then i got a beast X on my 700E

spent 1 day at the field learning the parameter changes and got it set where i wanted it. and there it is today.

later that day i installed one on my 600 and ordered another for my 450.

from there i spent maybe 2 batteries per heli tweaking rates and have been flying them as they are since.

i sold 2 of my 3G units for 70 bucks each and gave one away just to keep a friend interested in the hobby as he had started doing other things.

in my mind the 3G remains as BAD, but headed in the correct direction.

Who cares... its just money...

Check out my (nem3) "700LE 3G tuning - Flight reports" thread on HF. The only thing I'll agree with here is the tail. And I think I pointed that out in my first post.

Thanks for the info, well looks like i might go with a beast then, or the new 3gx if it ever arrives, but don't know how patient i am,
i like good scale flying as well every now and then, is this system the best one to go for to get a rock solid tail and performance.

The going price on the used classified sure does indicate its value then. Thanks for all the information. Is there any target date and price for the 3GX? I haven't found either yet.

T-heli,

Here is something i created in Real Flight that uses the software gyros as something similar to an FBL controller. RF seems to use actual PIDs and so you'll find user adjustable parameters that are very similar to actual fbl controllers and gyros. Pretty neat... the sim helis I've converted exhibit the same idiosyncracies when the parameters fall out of bounds.

3G will do just fine as long as you are not a 3Ds nuts.

Once setup correctly the 3G works very well. I very much liked the feel of the cyclic as compared to some of the other FBL units.
