FROM THE COCKPIT

WHAT PILOTS ARE SAYING

“This is exciting! I’ve been extremely happy with the Seneca II, flying it all the time. Can’t wait.”

— LSMike

“I insist on saying that this is undoubtedly the best plane I’ve ever flown in a simulator. I did my Multi-Engine course in the Seneca a few years ago, and flying it using the VR Quest 3 brought me a sense of nostalgia, reminding me of that time. Besides being very beautiful, the cockpit dimensions in VR are highly accurate to the real thing, as are its flight and ground handling. The aircraft has excellent performance in terms of FPS, which, for me, provided an immersion I’ve never felt with any other plane, especially using VR. I’m very happy with the purchase—congratulations on the work, Capt Iceman!”

— Maximilian Kaden

“Love the aircraft! it is a pleasure to fly. Thank you very much Capt Iceman!”

— Jugac64

“I enjoy this plane so much. Its comfortable true Piper cockpit looks great under all conditions. It is a joy to fly. The gauges are great to read (with beautiful back-lighting) and the layout is very ergonomic. It comes with the original POH (but you can also just go and fly – it is forgiving and straight forward). I think it is very immersive and I would clearly vote it the most enjoyable twin, maybe even overall most useful GA aircraft in XP12. The developer never seems to stop and has listened a lot to the users. I feel this is going to be a classic and a staple in the X-Plane community within short time.”

“I also did my MEP(L) in a Seneca II some 40 years ago now, so I was very pleased to find this XP-12 version. Still getting to grips with it but bringing back happy memories.”

— Colins2

“Ok, I'm going to put it to ya straight... I LOVE THIS PLANE! The Seneca has loooonnng been my fave and this one does not disappoint. I got this one very early on and have seen it grow into a fully matured aircraft model. I used to fly the Seneca V from Carenado but support for that fell by the wayside (it was developed right at the transition from XP10 to XP11) and it became unusable as XP11 progressed. I am so thankful to have a Seneca back in my hangar. Well done, iceman!”

— Stephen Kruse

“I did my MEP(L) and ME IR on the Seneca V, so I was very excited to have a Seneca in X-Plane. What can I say? This plane has progressed like a rocket in the last few weeks, and many more cool things are still to come! The developer is one of the friendliest and most open-minded person in the flight sim community I have ever spoken to, taking care about pretty much every input he gets to make this plane better and better! As of now, the CIS Seneca II is already a fantastic representation of a real Piper Seneca, with great handling characteristics (especially the single-engine behaviour, which is spot on and feels like the real plane), beautiful textures and very authentic sounds! So If you are looking for a great twin-engine aircraft that comes extremely close to the real plane, you are in the right place! Scroll up and hit the "Add to cart" button ;)”

“This is a beautiful airplane! It flies very well. I'm not a pilot, but the pilots among us say it is very accurate. The support is exceptional. It is updated regularly, including new features as they become available. Best of all, it does all this without killing your framerate while running. It is by far my favorite plane in XP12! Bravo!”
