Edited the History file and thought I would grab a couple photos from the for sale site and open them here because I assume they are current photos.
I posted this first one because it clearly shows off the rearward opening cargo door that first showed up on the 7/800 series Helios and Jaars turned into an STC to retrofit to previous series of Helios, or as a retrofit to replace the upward opening utility door. I still prefer the upward opening utility door because if it comes open in flt its a non event, it is possible to shut it in flight or if no one is sitting in the rear you just land and shut it. The rearward opening cargo door comes open in flt and it has happened on at least one accident report requires a trip to the repair shop. And the upward opening door if you don't already have one, only requires a logbook endorsement to install as a Helio factory option.
