25.1 hours last week or 3.6 per day. Made some real progress understanding the tradeoffs for different engines, ignition and props. Plan to place an engine/prop order early next week.
Continued work on Avionics costs and options. Started a failure mode document listing parts, failures, and backup plans. Realize I need to dig in more to understand how the Garmin components work together and what happens during various failures.
Reviewed feedback from a friend on Catto props and e-mag ignition and sent some questions.
Researched electronic ignition more. Leaning towards using dual e-mags for faster starts, some fuel efficiency in cruise and potentially lower maintenance cost.
Researched props more. Still waiting on response from Catto. Leaning away from Catto due to more maintenance for prop bolt torque and lighter weight will affect CG more and limit baggage weight. Leaning towards Sensenich FP prop since it has a low cost, low maintenance and weight is between Hartzell CS and Catto FP so CG might be okay. Found one used, but may pay for new one through Van's with discount for engine/prop order. Would like to go with Hartzell CS but initial cost is much greater and maintenance costs increase. It is always possible to upgrade to Hartzell later.
