Finally got some time to build my first GTM kit. This was modeled after the Group 44 MGB that ran in SCCA events in the '70's. The chassis is 1/16" brass and uses a Slot.it inline pod. The shell was modified slightly to incorporate the side pipes made from thin walled tubing.
This was my first attempt at building a brass chassis, so to keep it simple it was designed without any hinges or torsion bars. The Slot.it pod is mounted using small o-rings and lock nuts to introduce some flex. The adjustable front axle supports are separately machined and are mounted from below with flat head screws. The guide tongue is also mounted with screws, the only soldering was the guide tube. It was designed to use the original body mounting posts. All design work was done using Fusion 360 and machined with my small Sherline mill. I'm satisfied with the performance on the track; for such a small car it feels planted and can be pushed. There was a lot of trial and error in this first build, so hopefully I can apply what I learned to more complex chassis in the future.
This is a pic of the chassis bottom, I still need to trim the axles and finalize the front axle spacers.
Are those arches and chin spoiler as the model comes? Because there never was a Gp.44 B like that, but we all know Mr. T has a bit of a "thing" for overwidening a model.
Just to clarify, GTM never marketed this kit as a Group 44 MGB, in fact I think its refer to as a "club racer" I know the actual car did not have wheel arches, side pipes, tonneau cover, etc., and a formed green plexiglass windscreen spanned the entire cockpit. I used the early Group 44 MGB livery to try and capture the "look" of the actual car. Sorry for any confusion.
