Just finished the engine mounts off, engine is back in with the spacers, all up weight is 2.5kg, as a comparison the .28 powered HPI Pulse like my father in law has is 3.3kg and I am guessing that would be the weight without the RX batteries and bodywork etc.
I have also just taped my tyres, will glue them in a bit but its another stage closer to getting done, currently running the stock 14/50 gearing for break in/load.
