My heavyweight can be converted into a middle weight.
We were discussing that our latest cheap wheel chair heavy can be converted to middle weight by going to lighter armor and changing to less battery power.
We are at 40kg without a weapon and armor. We might be able to save 5kg from lighter batteries. So 20 kg in armor plates should be enough.
Tom I wouldnt build another middle weight, unless your knocking one together cheaply from unused parts. Kinda what im doing I guess.
