I bought an Ovation 3 to finish my ppl and get my instrument rating, I had about 10 or so hours when I purchased.
It is not the most common path but it’s absolutely possible and I do not regret the decision. Year one insurance was about 40% more than I pay now, but not as much as renting a plane, and my reasoning was that I would be establishing habits and routines in the plane I planned to fly.
It definitely took a lot more time with an instructor than a Cessna would take to be comfortable flying alone, but being that my plan was to go directly into instrument training, I was going to be spending time with an instructor anyway. I ended up flying with one for close to 100 hours as I was also transitioning to the Mooney.
My instructor had no Mooney experience prior to me. In retrospect, I would find a mooney specific instructor if I had to do it again. (I was not aware of Mooney space yet)
As long as you are committed to flying frequently , and understand that an advanced airplane as a trainer will take more time, go for it.
I’m not the only one here that did it this way, and the others who have opined, are pleased with their decision as well.
Also, contrary to a lot of opinions of those who did it the traditional method, I didn’t bend or break anything on my plane during training.
Go Mooney!!
