Here is something I worked up last night. Its a conversion from the Stormraven kit to turn it into a helicopter for my Merrikan Imperial Guard army to use as valkyries. it took me a few hours, ok a LOT of hours of test fitting to figure out what sort of design I was going to go for, but eventually I had an "Ah HA!" moment. Once that happened it only took 2 hours or so to work out how to build it.
