I got mine from Dave Partick directly, and it was the last 1 they had in stock. It was purchased in Novemeber though. They do get more ever 6-8 weeks it seems. If you have any interest in covering it DPM usually has the ARC's in stock. You might also try Chief Aircraft. They seem have a good stock of planes, and they do stock the DPM planes. Otherwise try your the local hoby shops they may have 1 or have an idea where to get 1.

If you get the plane you will love it. It is truly the best flying powered plane I have ever flown.

A couple of notes: If you acquire the DPM Ultimate 40 consider the elevator servo relocation, you move it to under the canopy to get better alignment on the cables for the elevator and rudder. Also beef up the landing gear block. Also beef up the firewall a bit if you go with a bigger engine than recommended.

Good luck.
