hi there
Ray, you are saying each balsa wood plank would need to be 5/8 thick – in that case – hows about sticking to the two 1/2 inch thick balsa wood sheets for the bottom? cutting the middle out and then sticking on the bottom one 1/4 inch thick either plywood or balsa wood – that should give you the correct thickness of planking. The other thing to take into consideration – if we read back and look what they suggest you power the model with – they are talking about an old Taycol motor or something and no doubt it will be the old fashioned cycle lamp battery (the 2 joined together which Everyready used to manufacture) – so, with todays modern technology either the motor/s are going to be a lot lighter and also you can replace the batteries with NiCads which can be low down in the hull.
The other thing is are you going to go twin motors or stick to the plan and build a gearbox or use pulleys to drive the 2 props with one motor.
