If Roughstuff was using the name of an older Transformer then he'd be Onslaught. They're both long military transports with large weapons mounted on them. He's got a distinct cab that's pegged into the trailer but unlike Erector and Overload the trailer doesn't pivot round the back of the cab. There's a pair of elevating cannons in the middle at the back with a missile mounted either side.
Transformation - Cab to Robot: Detach the cab. Fold the back of the cab's flatbed up to form the feet then fold the rest of the flatbed down to form the legs.
Nice solid robot - albeit lacking the knees of the standard Micromaster articulation having just turning shoulder & hips. The colour balance works well - olive green for the head & arms, grey for the chest and again for the feet with dark blue legs.
Transformation - Trailer to Jet: Fold the sides down top form wings. Remove the dual cannon. Fold the nose forward. Peg the dual cannon in behind the nose and fold the control bar up.
The jet mode is a bit blocky with the wings tipped with the missiles which can be removed. They've got am pegs so can be held as hand weapons or attached to larger toys. Roughstuff can sit in his jet with the control bar over his legs or stand on a peg which will hold him in place.
Nothing to complain about in either mode !
