In testing, the "i2" showed zero stalls with power at half or a bit below—even with full up elevator stick held continuously. This makes landings so incredibly satisfying. If you can land a trainer, you can land THIS. Just fly a little longer approach and use a bit more runway.
-
The scale outline of this airliner is SO easy to see, even at a distance. The huge tail fin and swept wing are to thank.
-
Though a jumbo jet, there was a giant effort to create the airframe as light-weight as possible. All while keeping strength for handling and trips to the field. That being said, the biggest gift this airplane offers is the smooth & easy flying- thanks to the low weight of the jet.

If you have a cartesian machine that is a "downstream" design inspired by the Ender3 and runs on marlin firmware, the Ender3 Gcode will very likely run fine on that setup. The Ender 5 is actually included in that group, though it's design appears to be a core x y. So we hear. Let us know otherwise please.
If you're printer is not listed here, please contact us and we'll get that posted for you.
