wow, thanks for all the good feedback!
these acctually took a lot longer than i thought they would with the orange black design on the hull, i painted the whole thing black then drybrushed it with Vallejo Gun metal. after that i gave the metal a wash of watered down black and picked out the highlinghts with the gun metal again. the long bit is the "camo" design, i painted these whole areas with VGC Khaki and then painted the black design on top of that. i then used blood red to cover the Khaki leaving a small space between the red and black bits to finish the design. i highlighted the red with orange fire and the black with a mix of black and cold grey. for the engines i used electric blue then highlighted with mixes using more white each time. i also painted this on the two metal "tail" parts to make it look like a glow off the engines. it's hard to put a time on these as i did them bit by bit over a few weeks but i'd have a guess at about sixteen hours for the two of them. this is mainly because there are some pretty akward bits to get into on these and painting the design on the hull wasn't so easy. i've got two Ka'Tocs undercoated and ready to be painted this week, i'll keep an eye on the time it takes me for them.
thanks again,
