How Many 4 Seat Twins Are There?

And how many use two Rotax engines?

From AVWEB:

Tecnam's P2006T MkII four-seat twin. With retractable landing gear, the P2006T MkII is considered an ideal trainer for multi-engine ratings, as well as an affordable personal aircraft for owners with missions involving flight over water or inhospitable terrain. Powered by a pair of Rotax 912SX piston engines, the P2006T MkII features Garmin avionics with two large landscape displays—and an S-Tec 55x two-axis autopilot. Tecnam sees Canada as an ideal market for its light twin, as well as single-engine models.

Seminole is 5 to 6 seats based on version.

It seems that, like the Seminole, the P2006T mainly is designed for the multiengine training role.

Aeronca built a twin engined version of the Champ that was designed as a low cost multiengine trainer. What an absurd looking airplane that is.

And how many use two Rotax engines?

Quite a few on Wikipedia, including this one from Ukraine.

While not a four seater, I just read about a custom twin engined RV-6A

Do you still have to "Burp" the oil system before starting the latest versions of the Rotax 912? Just curious as it is not a big deal, just a different preflight procedure than I was used to on any other opposed engine.

Back around 1992 I was told that the follow-on to the RV-4 was going to use a concept similar to one that North American Aviation came up with in WWII and had also been used in a special version of the Ercoupe. I don't guess it ever happened, though.
