try hobby hanger rocky i doubt they have ark 400 spares but trex 450 bits are very similar and you may be able to make up a fix. (take it with you)
when you reassemble it make sure to use loktite on all metal screws and ca glue on all screws into plastic

yer ok, theres like a alu hub that the two rear blades screw onto, it must of pulled or even undone itsself, so loctite will use when get a repair,
also belt tension am i right in saying able to touch the belts together but not the side walls is good ?
Thanks

The original white plastic ARK x400 tale blades? One of them snapped off?

These were prone to snapping I heard. Replace with the equivalent align trex450 part - straight swap.

not sure exactly which bits you have are good - but if your tail case is good - just buy this:

This fits onto the ARK tail case and clips onto the ARK tail blade grips - but the slider is driven top and bottom so there is a lot less slop.

hi rocky,

i had a tail blade fly off in mid flight the same as you. it only happend ones to me but it was very bizzare and did worry me. ( i havnt got it anymore)

with spares,, there's no one in the UK i could find. i found these:

they used to do a whole rage of spares but it looks like they only do a few upgrades now! ... fortunalty as boggy sais, nearly all parts are interchangable with trex450

cheers

yes mate with firm presure the belt should just touch

[fatmantom]

ahh just read moyesboy reply and the reason it didnt happen again is because i didnt replace them with the standard tail blades!

[moyesboy]

x400 spares are all avaiable at www.trexmad.co.uk

ah thanks for the help guys, will check out local hobby shop see if they have the trex equil part if not will search the net.
