Hi Dave, thanks for that, we like its looks too. We've cleared all our previous design and tooling hurdles, so finishing the first flying model should go very quickly now. We'll update our progress in this thread.
A normally aspirated engine generally loses 3% of power for each 1000' altitude gain.
We've an interested M2 customer who lives at 7000', and summer DA can add 3000' to that.
Without a turbo-normalized engine, he'd be taking off with only 70% of rated horsepower on a hot day.
The Rotax 915 iS is turbo-normalized to make its full continuous power up to 15,000', so it would be the preferred M2 engine for those in Colorado, Utah, Wyoming, etc. with field elevations of >4000' MSL.
