|Q: Is it possible to add more then 10 models to RC Flight Log?
A: In version 2.0.1 there is NO maximum limitation of models.
Q: How can I trace the amount of fuel used by the aircrafts?
A: Use field "Tanks/Battery" to trace the fuel consumption.
You can add the fuel amount as e.g. liter, decilitre, gallon, tanks etc. It's all up to you.
