Hey Steve! Hope all is well.
I figure if the Japanese can build a wood kit in those small shops I can't complain about building an ARF in my NYC apartment. I have to do all my wood cutting and carbon cutting in the tub of the bathroom so I don't get wood dust and carbon all over the place. Makes it easier to clean up too.
I only have one more year left here in NYC so hopefully I don't have to build any more planes in the apartment.
I had no personal experience with the OS gear motor prior to this and went off other peoples recommendations in terms of cooling. I spoke to some of the Australians that are running the motor and they did not mention any issues with cooling the motor, however, Henning from Norway had posted in the past that the motor was running a bit hot and added a heat sink that solved the problem.
I figured it would be easier to add the heat sink now than to worry about it later when it starts to get hot up here. The heat sink was 6 bucks, fits perfect, and took 5 min to glue it on the case.
