Dave, if I remember correctly AcTion have a link on their website with schematic layout of the electronics required for Slipway models, everything is matched for the particular model, even tells you which motor, battery and fuse combinations etc. Only going from memory here as it was some time ago that I built Slipways Maggie M and longer still when I built the Loyal. Give Slipway a call or drop them an email, Laurie there is really helpful so too is his better half! Slipway boats build really well and can superdetailed if you choose to do so. The Assurance is lovely looking model........good choice. May I wish you all the success with your build, take it slowly, follow the instructions to the letter and you will have a boat to be very proud of. I attempted builds from other manufacturers and failed (not necessarily their fault) but the Slipway ones were the ones I succeeded with and taught me the skills I needed never to fail again. Once again, good luck, enjoy and we will all look forward to your progress through to the wetting of the hull!
All the best from a fellow Dave
