Ok guys here is something that I need an opinion on. It can be good, bad or ugly I dont care. Just your honest thoughts.
Im thinking about going FBL and these are the options.
Convert 1 of my 2 flying GT's
Build my half finished pro kit that I think is going to cause me grief as everything is so tight in the frame
Or purchase 1 of these and start from scratch with decent parts
www.rc711.com/shop/alzrc-450-sport-3g-flybarless-helicopter-frame-kit-p-5652.html  Like the look of this kit and includes the head which means I can use my already purchased  Tarot head 1 on another build
www.oomodel.com/tarot-450-v3-rc-helicopter-kitshaft-driven-edition-p-60789.html  Another nice kit and TT and will use the FB head on the GT
As you can see Im not sold on the pros but maybe there is a reason why I should go down this path.
@ Phil. I know there isnt an Align option but Im sure you will add it.
@ Spiros. Mate I didnt block you, and its good to see the advice you have been giving to Kozzy. But Im not doing a FBL $9 heli.
@ All.  Looking forward to your replies.

I converted one of my GT's using the Tarot V3 FBL head. Im not sure if you have an FBL head already ?  You can buy one of them from locally here including postage -> http://www.aust-rc-tech.com.au/gallery/Flybarless%2BParts/tarot-trex-450-flybarless-rotor-head-set-tl45109/74084

This will drop straight onto the GT swash.  You already have the ZYX so you don't need anything else.

I think once you decide to go FBL you won't want to be buying any FB heads or parts for FB any more.  If you convert one of the GT's and use whatever spares you have in case you crash the second one and once they are all gone convert it to FBL as well.

Hi Again,

I can't wait to try this new Turnigy HeliDrive SK3 Competition Series 3600kv brushless motor.  It arrived yesterday and first impressions are good!

Trex 450 V2 Flybarless Conversion Videos

---

Hi Everyone, I've put together a video series describing the conversion of my HK-450GT to Flybarless. The videos are aimed at those considering their first FBL project and the videos are recorded in a build-along style.

Part 1 = Introduction

This is the first part of a 5 part video series describing the conversion of a HK-450GT (Align V2) helicopter to flybarless using a RJX type FBL head and the Tarot ZYX 3-axis gyro. This video is not technical and the actual build begins in part 2 where I will construct the rotor head. 



Part 2 = Building A RJX type flybarless rotor head For A Trex 450

A detailed bolt by bolt build video of a Hobbyking RJX like flybarless rotor head (Product ID: DMDL-450FBL) for a 450 sized helicopter. The head will be used on a HK-450GT which is an Align 450 v2 clone. I'm sorry this video is so long & I'll try to improve and condense the following setup vids. That said, this video is ideal for someone to follow along as they build their FBL rotor head! (see notes below)



Additional Parts Required:

1) Main shaft and fixing bolts (or recycle the one currently on the helicopter or Align HS1280T for a V2 conversion)
2) 450 Pro Damper Rubbers (I use Leadershobby Product # 9394001225892) or Align part HS1291
3) Swashplate (Recycle existing or I used Leaderhobby # 9394001224608)

Optional Parts

1) Genuine RJX swashlocker arms, Hobbyking ID: HN70010 (These are a better fit to most swashplate ball linkages)
2) Pro Feathering Shaft, Hobbyking ID: GT450pro-143 (Better tolerances & screws than the one in the kit)
3) Tarot adjustable linkages (TL2639) - Great for fine tuning blade track & pitch

Tools Required

1) 1.5mm Allen Key (*2)
2) Ball Link Pliers
3) 4mm Hex driver
4) Vice (optional or something to press in interference fit bearings)

Sundries

1) Bearing or general purpose grease (for thrust bearings)
2) Silicone grease for the damper rubbers
3) Medium Threadlock
4) Stud-lock (optional for seating grip bearings)
5) Multi purpose oil (optional for pre-lubing bearings - I use Labelle 107)

Part 3 = Mechanical Installation



To complete this step you will need:

- Tarot zyx gyro, flybarless rotor-head and suitable cyclic servos (preferably digital and good quality)
- 1.5mm Allen Key (Hex key)
- Phillips #0 screwdriver
- Ball link Pliers
- Medium threadlock
- Cable ties

Optional Parts used:

- Align HS1074T Ball Links
- Hobbyking peel-n-stick foam tape (4mm) PRODUCT ID: ST-FOAM-DB
- CA glue and or hot melt glue (to complement the cable ties in wire tidying)

Part 4 = Installing the software and setting up the Tarot ZYX



Part 4 of the video series describing the conversion of a HK-450GT to flybarless. This part looks at radio settings and software setup. I decided to use John's excellent programming utility (www.fbl.net.nz) as it is more polished than the original Tarot version. John has worked hard to update, fix bugs and improve reliability over and above what Tarot have done with their version. I use a Turnigy 9x as the radio but the settings should translate to any programmable radio. A few other points to mention.

1) I had to split this video so my opening comment about having a maiden flight ready heli at the start of the vid is untrue. Part 5, which is to a finish, will follow within a day or so!
2) The sound sync is lost slightly during the scenes recording the desktop on the laptop.

Part 5 = Final Setup



In this video I refine the mechanical and software setup. The video demonstrates levelling the swashplate, setting the pitch range and setting the blade deflections. There is also some shake down testing and blade tracking adjustment followed by a look at the some of the advanced software tuning.

To complete this step some cable ties, snips (or scissors) and a pitch gauge will be required.

I hope this is a useful resource to those interested

I looked into this and I think it's more of a pita than anything.  If you mount it on the heli you still need to plug and un plug it from the gyro when you want to use it.  Just get a USB extension cable from a $2 shop.

Hey Guys,
Finally had a chance to get a flight in today. A complete success... No Crash!
I did get a chance to chase a coyote for a bit. Kind of fun actually!
Video is posting now. Should be ready in a few minutes.

Joaquin

Hi Joaquin,

Nice flight. You seem very relaxed and not bothered from the visitor !
I had seen billions of squirrels in NY, they were everywhere! Here we have at the villages only. But not coyote !
BTW, squirrel has the origin of the Greek word σκίουρος, but once I saw so many in NY I thought it should be the opposite!

So, your LH GY520 got lost on its way and you use a GA-250 if I understood right?
Recently I bought another GA-250 to try as the first couple I had got were problematic. I have read about its bounce back problem but I hope I can use it with either the MD922 or the ES9257/8 servo and if it is needed to set the delay that the new batch has.

Get some more videos,

Spiros

Hi Simon,

I am trying mirror what and where you have bought you FBL gear from. I already have these main shafts from HK would they be suitable for your FBL mod?  http://www.hobbyking.com/hobbyking/store/__11516__HK450V2_Main_Shaft.html 

Regards,

Ian

I hope you were just unlucky and got a dodgy one of those INO-LAB servo's and it's not going to be a trend with them.

Brian, you will love this one.  Mrs E asked what I would be buying as a from me to me with my incentive bonus as the 550E bought last year has only flown 3 times that she is aware of and hope that it is not  another helicopter. So off to the gun show I go and returned with an automatic powder dispenser as well as a "sealed" box containing a "new"  mCPX., with 6 lipos, lots of parts and blades. "Bound' it to the DX6i charged it and then showed her how the little one flies inside the house.

She wants one too!!!!!.

Edmund

BTW. Shawn, I did a sub MOA with the .50 cal muzzleloader from 100 meters, 3 into 1 jagged hole

Now you do really need to hide the other one or else you will be in trouble. Or else box the new one up, give it to her then drag the other one out.

Nope all the same one, had the Blade box in my office and just moved the wooden wine bottle "hanger" to my car before I left for the gun show then packed it in there. After the crash it was rebuilt and looked new, thus the "new" indication. She did not see me flying it on the farm before as my car is parked in the shed and the wooden box contains "gun" goodies as far as she was informed. Many trees and other buildings in the way.
