I have never seen one any other way then a tail dragger. In the plans it shows you where and how to mount fixed gear or retracts or where to mount the mains as a trike.
As I recall there was an update in the box that explained this.
Same thing with pretty much all of the Bridi designs, you can go trike or tail dragger. I have never built any Bridi design as anything else. My DB was a tail dragger but I installed the mains in the back location and bent my own gear wire with a forward rake and reinforcement. They acted like a shock absorber that way!! Can you recognize BS when you see it??That was a big pile!!! I placed my LG blocks in the wrong location and was too lazy to change them to the forward location when I discovered my mistake. The bent gear thing was truth and they did act as shock absorbers but these planes land very smooth and don't require shocks. With a 91 you will want to bend your own gear legs anyway to get the clearance for the longer prop.
My only plane with trike gear is a scratch built Daddy Rabbit. I was talked into building it as original old school as I could force myself. That was a tough thing for me to do! I did do some mods that you can't see like an added servo to control the front wheel slaved to the rudder. A few others I can't remember.
