Have been having some very interesting communications lately from folks in two Yahoo Groups that have some overlapping interest in gyro vehicles. If you are not familiar with Yahoo Groups they are an interesting hybrid of forum and mailing list that can be very useful for several different communication needs.
(For example, I belong to one computer security related group that sends out one email per week to all members. That's all. Other people use the Yahoo group system as more of an opt-in discussion list--membership can be more tightly controlled than many forums. The nice thing is that you don't have to you get every single message that goes out to the list, you can get a weekly digest of all postings.)
With that in mind, you might want to consider these two groups:
Tilting: "This group is for sharing information and ideas about Tilting vehicles. HPV and all power source enthusiasts are welcome, but please focus on the CHASSIS."
Feet Forward: "This mailing list is for the discussion of Feet Forward motorcycles in all their shapes and forms. This covers both the various mega-scooters such as the Honda Helix, Foresight, Yamaha Majesty, Suzuki Burgman and Piaggio Hexagon but also the various low volume and prototype FFs such as the Ecomobile, Quasar, Phasar, Voyager and so on."
There is also an interesting web site that focuses on feet forward designs.
