Well I gues the jig is up, Gordon hit the nail on the head, the turbine(ated) dog in the picture is a hybrid that I am working on to corner the greyhound racing venues here in south Florida. I have seen nothing in the rule books to stop us so we expect to make a mint.
And yes I do have conversion kits for your pit bull or Yorky or whatever else you may have. Also available are the original propulsion units, (Big gas burners) (no pun intended) but in some cases prop clearence will be an issue.
