Additional trim.
I bought my 44 from HeliAir at Wellesbourne. The additional trim is something they have perfected over the years. it is great. You get (1) Door trims on all doors - pilot and 2 rears with elasticated pockets ( Ie no pax side pocket in view of the collective on that side) (2) Seat backs/ pockets. (3) padded rolls for the lateral seat support tubes (4) Nice little pocket between the rear seat backs for Ipod etc.
The additional leather matches the original perfectly.
The 44 has very basic trim - all a masterpiece of weight-saving. however, a couple of pounds transforms the interior completely, commensurate with the amount of dought you spent buying the thing!
Why not contact HeliAir and see if they will supply the trim kit by mailorder.
