Conversion Tamiya 1/12Ferrari 641/2 to 640 '89
Posted: Tue Aug 21, 2018 3:01 pm
I wonder why I never saw a conversion of the 1/12 scale Tamiya Ferrari 641/2 from 1990 into a 640 from 1989, although it seems relative easy, because there are many similarities.
I'm going to make an attempt and post a WIP here in the f1m site.
There are two versions of the 1989 car. I will do the early version with the low motor cowling as it raced from the season opening until the Monaco GP, cause I like the sleek lines of the car.
What are the main changes of the conversion? Here is a to do list:
1. Chassis:
Central fuel tank behind the driver's seat is lower than the '90th car and has to be reduced in the height and the backside straightend.
Lateral tanks need a new shape.
New roll bar and electronic boxes.
2. Floor needs only marginal change at the front air intake.
3. Motor can nearly be unchanged overtaken.
4. Only slight changes at the suspensions.
5. Simplified cooling system. The early '89 type had only water coolers in the side pods. The oil cooler was located in the V of the motor and is not visible. Although I had an intensive recherché I got no idea how it looked and worked.
6. Front and rear wing need only small corrections.
7. Cowling needs the greatest changes, but with some styrene sheets and putty it could be managed.
8. Decals: The 'Eni Chem' and the 'digital' signs are missed in the Tamiya Kit, but Indycals offers a complete 1/12 decal sheet of the '89 type.
I am going to comply with this sequence and will start with the chassis in the next post.
