I tested fitting the 104 into my mazda3... it almost fit in with the rudder on
, if it wasn't for a couple of inches at the roof near the dashboard. But, no worries with the rudder off at all, and the 104 comes with the removable rudder hinges as stock, awesome!
...so I can cart the 104, 87 and another smaller plane (or 104 and a few small electrics) in the car without needing the trailer. I'm quite happy with that
(and I'm actually quite proud of the mud on my car... it takes effort and pseudo rally driving to make a car this muddy)
