Does anyone have an accurate or close-to-accurate total weight for the engine and fuel system on their RV? (If so, could you share with which components are included and which are excluded, eg fuel lines, mags, engine mount, oil filter, etc?)
Background: we were talking around the hangar of just what would be necessary, and how much technology would need to improve, to get to an all-electric light single engine aircraft. This naturally gave way to wondering what is possible today. So the question we're trying to answer is what the "weight" budget is if we take out the engine, mags, alternators, fuel tanks, fuel lines, oil system, etc. and used that exact weight for an electric motor and batteries. For simplicity we're assuming a FP direct-drive prop.
And just to avoid getting off-topic, yes we know that there is a lot which hasn't been proven about electric motors in aircraft. We aren't planning on doing this, just wondering what the state-of-the-art flight range would be with current technology, and to figure out what improvement factor is needed for battery technology before reaching parity with avgas.
