Been out of helis for a while... other hobbies and family have eaten up alot of my time..... I have a vibe 50 nitro right now that has about 2 gallons through it... i want to get back to electric for the convienience etc....
I did have a trex 500 and loved it but here is what I am thinking....
My vibe has bls 451 servos with the 611 set up...this set up is perfect for me as i am only into mild 3d.....

Would the bls 451s fit the 550??... I see grandrc.com allows you to build your own combo so to minimize cost, i would use bls 451 since they are still basically new...i have always had good luck with the 611, yes its old but it is still solid.....

Now, the big question, FLYBARLESS..... how big of a difference is it...what advantage do i gain over a fly bar head....

When i stopped flying , i was able to do basic 3d stuff, backwards flying upright and inverted, funnels, hurricanes, loops, rolls, etc...
Not sure if i can still do this but i am sure it would come back....
...
Is it worth the extra cost of the flybarless????... Thanks for any input....

I was able to fit JR 8917's in a Trex 550, but I had to use frame spacers so that they wouldn't bump into each other. I don't know the exact dimensions of the Futaba servos, but I see no reason why you could not make them fit.

FBL is the way to go IMO. Less to break, less to assemble, flies great. I had to use spacers that were 5mm thick, I think, to space the bls451 servos. They do fit it just takes some extra work. I would make sure..you must call the hobby shop...and make sure you are getting a newer kit with the newest frame design. GRC may do a build ur own combo but he has a habbit of using old stock to do it.

FBL has 3 gyros...!!! One for ailerons one for elevator and one for rudder...!
FB has one gyro...!! Rudder or tail...
Tip ,, most of us think FBL flies better ... And it does make me fly better!! Love mine
But if you hate to use your computer for fine settings...
Don't get one...

Basically it feels like flying a heli on a good simulator and handles wind much better.

Feels a bit artificial to me which is the reason my helis are still flybarred.

Biggest problems with the 550 are the frames which are only 1.6mm thick and flex alot and the fact they need 2400+ head speed with 520 blades to get good pitch response which leads to low flight times if you fly hard (3.5 mins on 6s 5000 packs!).

60% of the time, it works every time!

Trex 550
The FBL controler is a 3 Axis gyro. It stablilizes the cyclic as well as the tail rotor controls. I picked up my 550 this summer. It is my first electric bigger than a 450 and also my first FBL heli. I love the way it feels. I dont do extreme 3D but I do some mild as I am learning. The 3GX gives this heli a feeling of being "locked in". It makes it realy stable when your stationary yet very nimble when inputs are given. I have flown nitro off and on for the past 6 years mostly scale the past 3. No heli I have had has felt quite this good. As for battery life, I am running Idle up at 100 95 100 with 12 deg cyclic and colective. I am putting about 3500 back into my zippy 5000 packs after 4:30 of flying. This is with a mix of loops, rolls, flips and a good bit of fast forward flight. Don't get me wrong there is nothing wrong with a FB heli but I can't see myself ever buying one again.

Oh man I just bought those blades!

This is totally WRONG!!!

I know because I HAVE ONE..!
First it flies way better then any helicopter with only a tail gyro.
Next ... Turngy ( cheap 5000mAh 30 c batteries) with sport and easy 3D I get 7 minutes!!! And will have a good 2 minutes of flight time in batteries still!!!! (( Not 3.5 minutes!!!))
I get more then enough power using throttle at ideal up 1 set at 80 to 85 and ideal up 2 at 90 to 100 .. You don't need more power this thing is powerful even at ideal up 1 running 80 to 85 throttle!!!
If you know how to fly without have 100% throttle all the time!!
Next,,, the frames.... Mine have never given me any trouble at all..
And if you want thicker frames??? They can be had for CHEAP!!!
I couldn't disagree more with this persons post!!!
And it does 3D great...! Just go to youtub and look at some videos ..!

Er ok which parts are wrong?

Thats like me saying that YOUR experience with the 550 is wrong!

There is alot of info on here about the frame flex and why do you think there are after market 2mm thick side frames?!
I couldn't disagree more with this persons post!!!
Are you for real?! Do you work for Align?!
And if you want thicker frames??? They can be had for CHEAP!!!
£65 aint cheap!

60% of the time, it works every time!

IMO, do not go 450. You'll spend more time fighting than flying. I had a T500 also and loved it! But I ended up selling it when I got my T550. This machine is a straight up BEAST! Get the 550, you will not be disappointed at all!

+1 on the 550. The 450 is ok for beating around and practice but honestly I dont fly mine now I have the 550. I actually thought about selling my 450 to see what the 500 scene is all about. The 550 is truely a beast. You would not be disapointed with a 550eV2 3GX. Right out of the box it rocks.

Oh man I just bought those blades!

To answer your question yes a FBL 450 will handle MUCH better than a flybarred 450. However any flybarred 450 can be setup to be insanely stable, its in the setup.

FWIW my 500 was the original belt drive version with GF frames and it is still probably the best heli ive owned!

60% of the time, it works every time!
