I had made a 737-800
based on Jet Airways sometime back but happened to break its landing gears and
lost the winglets. Luckily India happened to place an order for the P8-i Poseidon
which is based on the 737-800.
The modifications happened to be the raked Winglet, antennas all over the
aircraft the MADS antenne in the back, FLIR , Wing Pylons, IMMARSAT antennae on
top of the Tail fin.
I painted using Modelmaster Medium Grey and Aircraft Grey, Decals were
self made on a Alps Printer.
