ok well im due for an upgrade on the belt cp. So far i have:
servos- sg90's
carbon fibre blades
telebee gyro
also running one of darths fuselages. Im thinking of either getting carbon paddles and tail blades or a metal swash? what does everyone think or feel free to suggest something different.

carbon fiber paddles are not really that important, i'd go for the cnc swashplate and levers.

You might want to consider a programmable radio. CNC is good, but I rather save my money for repairs while climbing up the learning curve. Well is just me, people spent their money anyway they like. I see people put in every blings they could get, MOD it anyway they can think of, got a prgramable Tx, High-End CNC head and tail, add heli after heli into their fleet, and I'm surprise to see that they still have trainings kits on their skids and barely can lift their heli for hover without a crash. Well again, people spent their money anyway they like.

im waiting for a mate to buy a blade 400 and he is going to sell me the dx6i so in the meantime i would like to upgrade the heli. Flying is not a problem can fly easily just no 3d yet on a backflips.... i do kow where ur comign from tho lol i thought lighter paddles would be good? i dont really want a full metal head apparently there is no use as there is no real difference and it flie better with the stock head with cnc swash. im thinking now maybe a cnc tail setup?

CNC tail head set will give you crispier responses, of course you have to go for CopterX head or any other Trex style head. Belt-Cp CNC head is a waste of money to invest on. I upgraded my tail to CNC only because the little knob in the plastic tail box wear out on me too fast, performance wise, I don't see a difference. If you really want to blink up your heli, carbon fiber paddle and tail fin/blade is worth it cuz these things rarely break and not that expensive, performance wise, again I don't feel any difference.

Cnc head for a King or a belt are the same heads.
Total cnc head by Esky (or from Hong Kong) is a waste or money period. I have 3 head assy sitting in my tool box, some Esky, some counterfit. Ask Dumbdawg about his..
None are worth the alumn they are made from.
I takes a lot of hand fitting and retapping and cutting and refitting every bolt into every threaded hole, to make the cnc head work correctly. CNC head to work correctly very time consuming and you learn from experience on doing it what works and what you have to buy to replace what you screwed up!
As far as upgrading the head the one that you will feel and see right away isnot so much a upgrade but a overalll teardown and check to make sure you have your blade holders and all the bearings installed correctly,(the factory does not always do this correctly) along with the thrust washers and the end play is correct.
The metal Swashplate is a single fast and easy replacement item and also makes a noticeable diff in precision however the Esky swashplare is sloppy compared to the one that cnch heli sells as a upgrade. http://www.cnchelicopter.com/servlet...CNC/Categories.
Blade tracking is very important and blade balance is a must.
............And you were looking for a cheap easy bolt on that would make the sun rise in the west. Its like any other hobby, seems like half the fun is on the bench or ordering parts and upgrads...

mmm thanks for all th info has helped me alot. Im going to get a cnc swash and get new rods as the ones on there now r worn and thee is slop. from there on i will get carbon tail blades and paddles if i crash and break any of them but other than that every cent is going towards a nitro. Last but not least jsut to bug everyone again....... with carbon main blades, head hold gyro, upgraded servos, dynam esc and a metal swash, would a new motor pinion go good with all this for some more head speed?
here is a link to a swash, is this one good?

that one should work...

I also don't know what everyone else is talking about with the esky cnc head, I've got a set on my king2 and my belt cp and both went on with no problems. assembled, installed and flying in 15 minutes.
