Under standard condition 1liter of fuel is only 0,800 Kg.
All batteries are Lipo (ECU and receivers)= save 0,600 Kg
We use ACT receivers in DSL mode so we don't have any power-box nor DPSI
We only use a emcotec dpsi BIC wich is a double switch integreting a double voltage regulator.
We don't have pilot into the cockpit.
We had been very carrefully during painting operations.
And that's all.
