Sam, Good to hear from you. Nice work on the ESC project. Using Joe's controller to run the two OSMC's is a great idea. One thing I never liked about the OSMC project is that nobody ever developed a simple low cost R/C interface to control the bridges. You've done that in one fell swoop by adapting Joe's PIC. Nice job.
