Hi Justas, nice to see you on this forum!

I'm wondering, where did you get the weight estimate from? A typical build is around 550-600 kg. Remove the engine, tank, gearbox, and you still have around 380-430 kg. I tried summing up the weight of my rolling chassis, got around 240 kg at this stage:

Do you have any weight-saving ideas in mind?

[jstskn]

In my calculations

550 - 120 engine - 50 gearbox - 30 tank, petrol, pump - 50 other liquids and exhaust = 300 kg

300 + engine 40 + batteries 75 + 15 other equipment = 430 kg

Can anyone tell exact numbers? :rolleyes:

This is off topic, I'm afraid, but are you planning to change that steering rack at some point? It looks like you are going to get some bump steer, judging from where the passenger's rack ball joint is in comaprison to the suspension pivots.

I'm interested in what batteries you intend to use. Deep cycle lead acid traction batteries are damned heavy, 75KGs of batteries is not going to get you far. Or do you have some new technology batteries in mind?

Sure, it's just the donor's rack tied in place with some bits of wire so that I don't have to turn each wheel separately when pushing the chassis around. I'll use an Escort rack later on.
