This turbo normalized engine would be nice in a glider tow place as it could have full power output through the climb and of course gliding is a summer sport so haveing that constant power would be a great safety benefit.
@@gavsafety Firewall Forward, which is everything you need to install the engine on an airplane. That includes engine mount, cowling, exhaust pipes, hoses, clamps, electrical wiring and etc.
@@kvnkaveman Yelp, Im planning to build a twin and would def add two of these to it. I saw a video of one being built at the factory so that got me put on to UL
Is the UL 390iSA fully aerobatic or just inverted capable? is the crankshaft strong enough for snap rolls? I would love to hear from UL what the recommed, or anyone with real world experiance.
Yes , the ULXXXISA engines are fully aerobatic and capable for all aerobatic maneuvres. You can find more info : ulpower.news/the-ulpower-aerobatic-option or check out this video : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3AtKqXSFOFg.html
@@dominiceller1821 After the first 15 hours (break-in period), ULP Acro+ oil additive must be added at every oil change. It creates (a kind of) oil film in the engine, which guarantees lubrication under all circumstances. We already had it before the twister incident, but then started promoting it extra.
@@arcanondrum6543 Well that's aviation for you. Simple things made expensive, but the quality of this is far above traditional aircraft engines for sure. You could buy a Volkswagen conversion tho
Just add boost... what a racer would say, but safety would be nonexistent. To be fair the UL engines have very low operating temps a s sufficiently large displacement. The standard speeds arguably make them better than Rotax. So, faster rpms and some boost, throw safety out the window, and you have 300hp
I'm still waiting for you. L to admit that they need to add a lien of peak operation button. When I get to cruising altitude I want to fly lean peak. It's better for the engine and all they need to do is provide cylinder head temperature feedback to ensure that you don't overly lean it. If it does get caught, then you go back to full rich, let the computer control it. People are going to have fowled plugs unless they do this.
