What is so bad about 3gx?
As the title says, I'm interested in knowing what it is about 3g that makes it sooooo terrible, as it's made out to appear. I always hear it, but never hear why. I'm in the market for a 450 combo, and although I want a flybar, I couldn't help notice the mere $30 extra for the FBL.

As it stands, I do not really care for the FBL hype, and I do not want the heli making small corrections for me, so my mind is rather made up on FB..... though I could be persuaded otherwise (did I really say that?! ).

Anyway, is 3g really THAT bad?

Trust me FBL is where it is at man. I was the last guy at my field to switch over. I switched to FBL and my flying has improved exponentially not to mention they handle high winds better.

3G is the older unit and 3GX is the newer unit. I have a 3G in my Vibe 50 and a 3GX in my T-Rex 550. 3GX can act as a receiver with just a spectrum satellite for JR/Spectrum if you want but you can use your own receiver too. Both units are great. I have a Micro Beast in my Fury 55, some of my buddys have VBars so I can tell you they are all good.

What Radio do you use? Spectrum/JR? Spectrum offers a receiver now with a Beast built in. http://spektrumrc.com/Products/Defa...dID=SPMAR7200BX

I would do a search because once a week someone starts a thread "What's the best FBL unit?"

I think they can all be good if tuned correctly. Another thing that matters is what other guys around you use. That was you can get help tuning them if the manual fails to explain something.

I have the 3g on my 700E and have almost 800 flights on it and the 3g has performed flawlessly. VERY easy setup. Low maintenance. Flies great. I have flown the 3gx on my friends 600E and I actually like it a little better. I do a LOT of piro maneuvers and the 3gx holds better and is a bit smoother during piros. I have also flown the V-bar on 3 different machines and in my opinion, it flies the best but a V-bar runs around $300 while the 3gx will set you back around $100 and the 3g runs maybe $40. If you are a pro level pilot (Jamie Robertson, Nick Maxwell, etc...) the V-bar will probably suit you better but for all of us normal guys (and I fly pretty hard 3d), the 3g or 3gx is a great unit!!

I've never flown the Beast-X or any other unit so I can't weigh in on those units!!

The users make FBL systems sound bad because some don't take the time to set them up.Only issue I had with my old 3G was it felt laggy around center....

How would a FBL heli be for a(Sport flyer)someone that just likes to fly around normal maybe do a few maneuvers, hover,etc? Do they do nice smooth banked turns? I flew a few of the FBL heli's on the sim and they seem to fly a little different when going into a banked turn. Not as smooth as FB heli.

@ Blade strikes

Not sure how how you can say the 3g is "laggy" around center. Mine will snap on a dime and leave you nine cents change!! Id your setup dead nuts on? Do you fly with expo? Have you gone into the software and tweaked your setup? I have found that people who complain about the 3g don't have it setup properly. When I flew mine "out of the box" without setting up the unit through the software, it was a bit mushy or laggy in your terms but 5 minutes with the software, she came alive and I love it!!

Here is a video of a very easy flight with 1800 head speed (the 700E usually runs around 2150+) and you can see how well the machine flies!! When I put her into idle 2, HANG ON!! It's crazy snappy!!

I actually prefer flybar for general sport flying style also. A FBL gyro will always attempt to keep the rotor disk at a particular attitude - it's sort of like turning your heli into a pattern plane.

In the hover, there's no comparison - a flybar is much less workload to keep still. It has a kind of dampening and self-recovery that FBL units really haven't mastered yet. The Vbar is probably the only exception to this, I found it to be the closest to a flybar in terms of being able to keep still in the hover. But even it can't come close to the stability of a well setup flybar in hovering.

I now fly my FBL 700E with no stabilization electronics on the cyclic at all (BeastX just on the tail). I find the hover to be more natural when NOBAR than it was with gyros (though the pilot workload is a lot higher for everything else).

So I'm with you on sticking to the flybar. Plus, flybars don't drift when you have vibes (there's no such thing as a vibe-free heli and FBL gyros just Aren't There Yet when it comes to being resistant to vibes)...

I have heard more bad things than good things about Align 3G/3GX. Stay away from it if you can.

I put a few 3Gs on a 700N and a 600N. I never could get the 700 right, so I went to BeastX. The 600 flew great with minor tweaking. I think the 3Gs are very sensitive to [articular vibrations or something, and if they don;t like your heli, forget it. I end up flying my 600 a lot and really like it with the 3G. I've got BeastXs on everything else and love them.

some weeks ago i flew my 700 and 550 in front of someone who had no experience with a 3gx, only what he had heard or read. he was skeptical as to why i would trust either heli to a device he was sure was junk. by the time i left he had a different opinion. i have five of the little buggers in 2 700s, 2 550s, and a 500 and they fly fine. there are no secrets to setting one up and the new software is similar to bx setup.

That is why I had a 3G and 3GX and never installed either one. For some they work great. For others they don't work and there is no solution. It is a crap shoot if you will be successful or not. The other brands I have tried (and still use) work well.

I was the first to change over to FBL many years ago. Now out of our 10 or so pilots in the club, only one is still FB.

My recommendation is FBL but not using Align.

The 3GX works quite well, and is very easy to setup.

If you have extra cash then sure get a CGY 750 or V bar, but the 3GX is quite good for the price.

I have used the 3G and the BeastX and both were PERFECT. The 3G is STILL in my T-Rex 700E and works excellent. No issues at all. It does help that Alan Szabo Jr. helped me set it up but I'm still using it and loving the way she flies.

The BeastX is excellent too and I will be putting that in my Diabolo. I don't do any hardcore 3D.

so the whole team Align who is flying the 3gx doing extreme 3d daily (both the szabos) are flying garbage? Think not 3gx take more time to get flying right but a reset something not right only way i seen people be able to do it is by rubbing feet on the carpet then touching the unit OR by not properly supplying the unit with enough power and amps to run a FBL system on sattelites only. Then it will brown out yes. Did it with the align 2n1 i had due too only supplying 6 amps switched to the SG reactor x2 getting 16amps and loving it!
