If you want an exact match, I'd recommend Xtracolour X32 RAF Desert Pink, available from Hannants in the UK (www.hannants.co.uk).
This is a little darker than photos of real machines and will require a bit of weathering to achieve a realistic finish.
If time is pressing, Humbrol 93 Matt Desert Yellow is a pretty good match and probably just needs a dark wash to achieve a reasonably realistic look.
Hope this helps,
