I found this link at the DAX RC web site in Japan, http://www2.ocn.ne.jp/~dax/
The Pattern Planes from DAX are on my list when I win the Lottery.

Here is the Pit Assistant, as the web site calls it.
The Pit Assistant laying on the ground is Y32,500, approx $325.
The Pit Stand holding the pattern plane is Y42,000, approx $420.
