Can I expand your list
10 - Komet W4.1
11 - Komet W4.2
The last one only has the C4.1 gearbox, all the rest is replaced with improved parts
The goal was to make a c4.1 with a correct weight balance & flex, without a chassis that bends when you're having a bit of fun, and without hingepin hangers that have play after one meeting.
