I was a big fan of the Impulsor 'swift attack grav-transport, the legendary flying Rhino in my mind, however I wasn't a big fan of the half truck open back but saw a decent enclosed kit from Models and Minis for a good price too. Seems that it's a one-man business and he has a massive backlog of orders, so there was delays (expect long delays) but after some correspondence and explaining his predicament I was happy to wait, and not disappointed, high quality kit and sweet look too. Compatible with the top turret ring connection and I easily magnetised the ring to swap out turrets.
With the enclosed hull, I REALLY like the shape of this kit, and can't wait to get a few Gladiator tanks too, in my opinion much nicer than the floaty-Land Raider Repulsor. This feels like a decent modernisation of the Rhino kit (now its enclosed) and if you don't mind a wait (again at time of writing - may improve), I thoroughly recommend getting this conversion kit.
