Both Thielert and Austro Engine have very strict requirements about maximum negative loads on the engine and in most installations, intentional negative manuevers are prohibited (although the aircraft structurally withstand the CS-23 required load). I doubt you'll see a diesel-equipped aerobatic aircraft very soon, especially with all current engines having such high fuel pressure requirements (Common Rail). However if AustroEngine (in co-operation with Steyr Motors) really developes a mechanical injected diesel engine, it probably could be modified with a dry sump for aerobatical flights. The real question is: is the market for such an engine large enough?
