Although anything is possible, and admittedly the pictures of the DL100 on DLEnginesAustralia and DLUSA are most probably of one of the prototypes of the engine, the engine shown in PerFlight's post is very different to the engines shown on these web pages. Besides the obvious difference of the milled / cast engine case, the prob hub and engine mount are also vastly different.
