I believe that I have one of these kits in the kit mountain in the loft. I’ll have a look this evening and see if I can find it.
I didn’t know that it came with the Perseverance chassis as standard. Even if mine doesn’t, setting up a compensated chassis is straightforward.
Have you assembled the coupling rods yet? That will be the first thing that you need to do. Having never opened the box, I don’t even know if they are rigid or jointed as they come in the kit.
