I've picked up MP4/27 again this weekend. Decided to glue together as many body parts as possible before paint. Because this one is going to be curbside, I've built out almost full body shell. I've use floor as a guide for better alignment. It actually went together better then I've feared. And parts have aligned to each other well enough. I still fear for the version with engine, where I would not be able to glue parts together and panels will have to remain removable. But let's see first if Fujimi actually produces kit with engine, then I'll worry about it, if I decide to buy it. I've also put together nose cone, gearbox and some rear suspension parts, and floor parts.
