I'm converting a Hen long 1/16th Sherman M4A3 in to a Firefly for a mate. He wants a model based on the M4A4 Sherman even though the hull is too short, so this will be a representative model not an accurate to the mm model. It is further compromised by the fact that the baseline model is radio controlled, so the early 3 part gearbox case will not fit because of the gearboxes to provide drive to the tracks. The changes will all be scratchbuilt, 3D printed from my own designs except for the barrel, commander's cupola, headlights and rear lights. The lights are fitted with LED's and work when the model is switched on and under radio control.
