My Dave Patrick Ultimate 40 is a terrific flying airplane. I have a Saito 72 on it and it will go veritcal forever, and hover at just under 1/2 throttle. It will also fit in my midsize family sedan's fully assembled. In the trunk that is. It has a 44" wingspan. It's just big enough that the wind doesn't toss it around too much and yet small enough to move around the house and car easily.

You wouldn't want a 60 2c on the DPM Ultimate 40 though. An OS50 2c would be the largest.

If you really want a 60 size look into the Carl Goldberg Ultimate. It was also designed by Dave Patrick is a great flyer.
