Good attempt Righty,

Try giving SuperCal a go http://www.supercaldecals.com/ its excellent its basically make your own water slide decals, so you can have anything even a nakid lady gracing your plane if u so wish

Its extremtly easy to use using a standard printer............ i found is great for my scale warbirds doing stuff like kill markings etc which i couldnt find anywhere

Hope thats of some help............
