Avid Model C Runs! NSI EA81

[Doug123 26]

Updating the progress for my Avid SN573 Model C. The new custom exhaust is installed and the NSI fired right up.  The Ellison Fuel Injection operates normally and the oil pressure 65 psi.  Sorry it has been two months since my last update, but I had two non elective open hand surgeries in August and September.  The surgeries were successful and I am flying again! 
 

Elevator has new polyfiber, using Stewart Systems, and the instrument panel is still in work.  My goal is to taxi her next week, and I have a young Kitfox pilot to take her out when the ground runs prove to be satisfactory to ensure of she has good flight characterstics.

What was the weight difference between your stock NSI and custom exhaust, looks great compared to the Sherman tank NSI muffler. Is the center an actual J-3 can muffler?

No it’s a custom can design that mimics the J3. Custom Aircraft Parts in El Cajon CA designed and fabricated the exhaust.  Weight difference of approximately 12 lbs.

The original electrical setup was two Duracell deep cycle batteries located near the tail that  weighed together about 45 lbs.  After the aluminum radiator and exhaust, one 25 lb battery was removed and a 20lb ballast needed to be added for correct CG.
