You can do a new drive system that will be more reliable for the Simplex, I am assuming you have this type of Simplex, as in the first drawing "Simplex". In recent years there has been a lot of new developments with micro gearhead motors, you can get them at good prices To drive the Simplex I assume 7mm scale it has 18" dia. wheels [10.5mm] you will need the motor with the 150rpm output, that will give you a maximum speed of 8mph, I have attached another drawing set to 7mm scale in size with the motor and gear housing over laid in red, and you use small pulley's with a 1mm cross section O ring as belts, if you are interested I can make up the pulley;s you need if you can let me know what the diameter of the axles are. ------ Original Message ------

Although I never quite finished constructing the bodywork of Roy’s Simplex kit, I did get the construction of the chassis kit complete to the extent that the whole thing was a runner and Adrian said that that was the only model, other than Roy’s own, that he had ever seen operational. Certainly getting it to that stage was an interesting experience with the tiny can motor that Roy supplied becoming distinctly hot even once I had managed to get the two-stage gear-train running smoothly-- This email has been checked for viruses by AVG antivirus software. www.avg.com |
