I want to build an RV, but I want an RV with two aircraft engines and centerline thrust. Has anyone modified their RV to allow for a second engine? I would like to make it an aircraft that I would feel comfortable flying real IFR at night in since losing an engine would be a non event. A centerline thrust RV should with either one of the second engines be capable of continuing to the nearest airport and if necessary climbing 1000 fpm. I was thinking of modifying an RV-10 with a Cessna 337 type tail or doing the same to a RV-7A or RV-8A. I hate to reinvent the wheel and hope someone else might have done something like this to his RV.
