You might get an LRF out of this lol. Well, being as the Leaf was some while ago...ya know
The Virus has a look of a full sized sport glider. It's really a fun design, great choice.
Wheels of my choice for this would be a tricycle group from an ITC Microfighter. If you have one, or know someone with one, the whole 3 wheel assembly is about 1g. Hot Wheels cars would be another thought, if you sanded down the tire wall thickness. By the time you'd be done, they may be even lighter.
Or, discs of foam with a pin through. Bit of soldering to look and act like welding and the job is done by many routes
