800xp Vs 850xp
Ciao Roja don't worry,
The 800xp with Honeywell it is absolutely identic of the 850xp ( with Collins proline).
It has just very small diff. related with electric sys( very few... it just doesn't have dual inverters, due to more modern avionics with inverter integrated).
So don't worry,take a look of what you found in Smartcockpit.
it's absolutely enough for the moment. It's a very simple plane, just a little bit too old therefore with switches like spread everywhere...but apart this is a good and reliable A/C.
ciao have fun.
