Remarks, FAQs and Q&A
So many people have asked "What makes this plane special" that I've put together some answers to the most frequently asked questions. Also, included questions we've received from interested parties.
1. During construction, careful attention was paid to observing and following all manufacturers' recomendations and specifications.
2. Firewall-forward was engineered after the prototype had 600 hours.
3. Fuel lines are all 0.5 inch.
4. Dry-sump oil system.
5. Dual electric fuel pumps offer redundancy for the engine-driven pump and for each other so you have starting redundancy as well.
6. Dual MSD ignition.
7. Single plugs.
8. Dual batteries for electric system redundancy. Batteries replaced Nov 2011 and added new battery tenders.
9. The wing stress analysis was done analytically -- that is without sand bags as it would take a bunch -- source was an instructor who taught structures at Embry Riddle University.
Questions and Answers by email
Q: Is it registered as a 2-seater with the FAA?
A: Yes, It is a registered as a two seater.
Q: Is it registered as an aerobatic aircraft with the FAA?
A: It is aerobatic and entered in the log book.
Q: Will the engine work inverted?
A: The engine does not have inverted oil or fuel system. The plane can go inverted but not pull negative G's without losing oil pressure and unporting the fuel pick-up tube.
Jim Stewart put a christen system on the prototype for an inverted oil system. I do not know if he ever did the fuel system. The original P-51 did not have inverted fuel or oil systems.
Q: What kind of fuel are you currently using?
A: I have only used aviation fuel but premium auto fuel can be used as well.
Q: What is the cruise indicated airspeed (no ground speed) and fuel flow?
A: It cruises at 240 MPH and burns 18 gph. Although I flight plan 20 gph.
Q: What is Vne?
A: Vne is 300 Kts indicated.
