Am thinking of a winter project with my t rex 500, am thinking of putting a 4 blades head on it and i was wondering if its hard work and what would i need to know. The align head that am going to use they say i would have to use a fbl unit with it and am thinking of using the either the mini v bar or the beast x so is there anything i would have to set differently in the units? and about the mechanics what would i need to know?

4 bladed head, Is it hard to setup?
Do what u do best
T rex 700LE beast x radix 710 fbl blades
T rex 700LE stock radix 710 SB
T rex 600LE beast x radix 600 fbl blades
T rex 550E beast x align blades
DX7 and DX8
Phoenix sim
And plenty of spare parts

If you are going multi blade head, my best suggestion is start reading about phasing! That is where most problems arise with setting up multiheads.
If the bladess are not phased correctly - either mechanically or electronically the heli will not fly very well. A quick way of setting mechanically is by putting one blade parallel to the tailboom, then moving the swash driver until you get no movement on the blade when Ele/ali is applied. But most fbl units these day will do it electronically and make the setup a great deal easier.
Do a search in google for multi head setups, there is tons of info out there to read up on.
Or if you have big balls - fly it without stabalization. It can be done, but i can tell you first hand it aint easy!!

My 4-blader is entirely mechanical - no electronics involved at all. The biggest problem I had was tracking the thing! With 2 blades its easy - tweak a blade, and if it gets worse, tweak it the other way! With 4 blades, you HAVE to identify which blade is out - and if more than one is out, it gets even more complex!
On my machine, I found a piece of carbon tube that was a good tight fit between the Beanie dome and the top of the head. That gave me a 90 degree reference so that I could use a standard pitch gauge for the initial set-up!
That got me pretty close, but one blade was clearly a bit out. Trying to identify which one whilst trying to hover a slightly skittish, unstabilised heli is tricky! It took two of us in the end, one to fly, one to look!
I also found it easier to use a bit of PVC tape and apply it to each blade in turn to identify which one was out. I tried different coloured tape on different blades, moving the tape to different positions on different blades, but found it easiest just to apply tape to one blade at a time until the culprit was identified.
As to virtual flybars - do you still have stabiliser wheels on your bike???

No matter how much you push the envelope, it'll still be stationery.
