It wasn't offered in tricycle gear. We also run a rotax 912 engine and have the tail the same size as a model 4. EXPERMENTAL. We have done a lot of modifications. Part of the fun of owning one. what I found interesting is the manual you sent me identifies the MAC and empty weight for a model 1. listing the max gross as 950 rather than 850. We are going back into phase 1 testing and plan on increasing our gross weight to 1000
