Firesprink, did you see that OFNA has revised the Ultra GTP? much cleaner layout, but its still using the Ultra chassis so no real rear brace, and it probably has the crappy Ultra differentials front and rear. I wish Hobao would make a rally game car based on the Hyper chassis. Even though the Hyper 1/7 is based on that chassis. I've discovered that the Hypers are MUCH lighter than the Jammin counterparts.
