I am nearing the end of building a model of the 36 inch version of the KielKraft RAF Crash Tender, from the original plans, and need the deck fittings for the craft. I have managed to keep the weight down to 3.5kg by means of careful wood selection. She is powered by two Graupner Speed 600 ECO motors which produced a lively turn of speed at her first trials on the water the other day.
I have obtained a set of white metal castings of the deck fittings but found the weight of these are 1 kg and am concerned that such an addition, increasing the weight by about a third, would have a detrimental effect on her performance.
Does anyone know if resin castings of these fitting can be obtained from anywhere?
