Mistral states that you can't do any aerobatics, loops, rolls or otherwise with their engines why is that?
Do we have that problem with our homebuilt 13b's?

I don't know the reasoning. Perhaps they don't offer dry sump oil systems.
On the other hand the Mistral motor mount is not the best for aerobatics.
Perhaps that is the reason. Any motor mount should be beefed up
or specifically designed for aerobatics IMHO. The prop gyro loads
are hard on the engine mounts as well as the PSRU.
