For your question: There is no such thing as a maintenance manual for an experimental aircraft. Not sure what the regulations are for your area but assume there are different requirements for certified aircraft vs experimental.
Closest I think you can find is an example of what others have done for their condition inspection (equivalent to an annual inspection for the certified world). Looks like Tim Olsen has on on his website: https://www.myrv10.com/N104CD/maintenance/20070225/index.html
As you go through the process for your new aircraft and find additional items you need to inspect, or things that don't apply to you, just change those items on the checklist! (At least that is what is expected here in the US).
Hopefully this helps
