Decided to try my hand at kitbashing a Venom transport for my Dark Eldar, here are the results so far
So on this side view shows the basic idea for my venom it is the back half of the raider coupled with the front half of the Vyper.
Front shot showing twin Splinter Cannon placement (well they are shuriken cannons at the moment) fastened at two points, a plasti-card plate covering the gap left in the raider back section and part way up the fuselage.
Replaced Vyper pilot body with wych body and head had to clip bottom of the body to get a fit and arms are a little wonky but overall effect isn't bad at all and certainly better than the original eldar pilot.
Connection point between raider and vyper required a slot cutting in the raider section deck plate which the vyper section slots into fitting the bottom of the cockpit flush (ish) to the raider section.
Back view no different to a Raider need to put on jets
So now I just need to dark eldar it up a bit I'm thinking blades bayonets and chains will be the order of the day.
