Hours Worked = 3

The RV10 firewall is a single large sheet of stainless steel. It’s not made from aluminum like the rest of the plane because as a firewall, it’s supposed to keep an engine fire (if in the unlikely event one happens) on the engine side, and out of the cabin… where I’ll be sitting. Wind blown AV Gas burns at around 1900 degrees Fahrenheit, but aluminum melts at around 1200. This makes the stainless, which has a melting point of around 2700 degrees, a much better material. Speaking of fire safety, I will also be replacing the stock aluminum heat selector boxes with stainless, for the same reason. Furthermore, I’m going to be adding a ceramic insulation on the engine side of the firewall, and leaving the inside of the firewall and all the parts directly attached to it uninsulated and unpainted. If there is a fire, the firewall is going to get HOT, no matter what… and paints and insulations have a tendency to let off fumes and smoke. With the insulation on the outside, and no paint on the inside, I’m minimizing as many hazards as possible.

The structure of the firewall is a large sheet of stainless steel, bunch of aluminum angle that sits on the inside to give it rigidity, and some strategically placed steel brackets that will take the load of the engine and nose gear.

Today, I got everything clecoed in place and match drilled.

    Awesome. Looks like it is going to be a utility category craft…what will useful load be? Have you selected a powerplant?

    Actually, the RV10 is a standard category design (+3.8/-1.5 G). The useful load will be between 1100 and 1000lbs, depending on the final weight of the finished plane, and I’m hoping to have a full fuel payload of over 700lbs. In any case, I’ll be able to carry 4 adults with luggage, and go fly 3+ hour legs no problem (like MSP to Denver in 3.5 hours!)

    As for an engine, right now, I’m leaning towards a brand new Lycoming IO540. It’s the engine the RV10 was designed for.
