Have the Hot Rod set with Chally - both are about as 5+ as a kit can get in terms of 'challenge' to assemble.
Looking forward to seeing if anyone here or on MCM is going to do a step-by-step build to point out the snares and brambles in the build(s).
Would also love to take a shot at building the original twin Buick that Ivo was running that was a NHRA record setter in what I'm recalling as maybe the nitro ban (?)
