At 490 pounds that is fully 100 lbs lighter than my Air Command Tandem! I want to get my hands on one of these and install a YG4. 30 more HP, 30 less lbs! I already spoke to the Aussie about it at length several months before TAGNA announced here, but he wanted to wait until the program had a chance to mature a bit before letting me try it. I promise you, though, one is coming in the foreseeable future.
