François Posted January 10 Author Posted January 10 (edited) 20250108_085356.mp4 I received the new gearmotor and after some tweaking and alignment issues, I got it mounted in front of the radiator, directly in line with the crankshaft. It will eventualy be hidden by the blower housing. Here's a little video showing the new gearmotor in it's new location at work rotating the car's engine and transmission. You will notice the transmission's output rotation being controlled by the shifter. 20250108_085356.mp4 But then, all hell broke loose and the crankshaft snapped! So after a complete dismantle of the lower engine (it's a vefy good thing the head assembly in bolted so it can be easily removed), I was able to replace the broken portion of the crank along with 2 connecting rods and caps. Broken crankshaft after repair being reinserted in the bloc I printed and assembled the 2 differentiels and temporarily connected them to the transmission output and was then able to drive everything from the gearmotor 20250109_175732.mp4 Edited January 10 by François
François Posted January 18 Author Posted January 18 I've been more busy skiing than modeling this past week but I still managed to finalize the blower drive. I decided to add a subframe between the radiator and blower's front face to facilitate the assembly and paint. This way, I can chrome both the radiator and blower front face at the same time without having the blower housing in the way. Since the blower housing will be painted the same color as the bodywork (color to be determined), I made it in two halves that can easily be assembled later. I also made a small drive shaft between the crankshaft and the blower. If this was a real car, this shaft would drive the blower from the engine but on the model, since the gearmotor is hidden in the blower it's the other way around.

Spex84 Posted January 20 Posted January 20 This super ambitious, and I'm enjoying seeing the progress you're making!
François Posted January 21 Author Posted January 21 (edited) Thank you everyone. I was finally able to drive everything from the gearmotor hidden in the blower. From the blower spinning dome to the 4 rear wheels. I small victory for me! 20250121_164637.mp4 I'm printing parts while waiting for a revell paint order I did for the frame, suspension and drive components (silk black). I decided on the body color, it will be Tamiya's gunship gray which is a blueish gray. It should look a bit like the prop car made for the movie . Edited January 21 by François
BK9300 Posted January 22 Posted January 22 That's quite the accomplishment, François - so much detail to take in!
François Posted January 25 Author Posted January 25 (edited) All the steering components have been printed and assembled, everything fits and works as should. 20250124_213251.mp4 I also started to print some boby parts, here's a test print of tge right side tool box. Edited January 25 by François
