Sorry, no pics yet, but the diet was very successfull for me and the challenger :) I dropped 4 kgs, the challenger is 0.5kgs lighter. Basically i slimmed it down for the weight of the engine, which is about half a kilo as well. When i get the shipment of 3x3 connectors, i belive i can reduce the weight even further.

One thing i imediately noticed after i put everything back together is, how much better the chassis is. It's much stiffer than it was before, despite the fact that it's a whole 200 gramms lighter. Everything just looks more finished. And nicer. I'll post pics when i'll rebuild the engine, and the weather improoves. Right now it's cold and rainy. Not very good for outdoor photography.
