I got the idea that I could use channels 3 & 4 on my Flysky GT5 to control the free spool and winch on a Boom Racing muscle winch. I installed a micro-servo on an aluminum plate & attached it to the Boom Racing winch with mounting tape. That servo activates the free spool from channel 3. The winch itself sits in the battery tray of my capra on an aluminum plate attached to the Capra once again with mounting tape. The winch is controlled on channel 4. It works great.
