Things to change discovered after being at the field for some tests:

1. The tail mechanism needs to be centered to have a rotation angle on the left as much wide as on the right
2. Remove leds on the legs. They are not visible. remove and place them elsewhere.
3. Change front legs to have same length as legs on the back.
4. Make covers for protecting the PDB (power distribution board: buy a 1mm thickness plexiglass) and the upper part over the FCB (flight control board). By now we have two holes for maintenance and configuration support that need to be closed.
5. Add the beeper for battery power control and discharge alarm, use 3M dual lock to fix it on top of the model.
6. A better way to fix the battery on the top of the model ?
7. Remember that you may land on wet grass and water may comes in. This is dangerous for the electronics.
