Hi,

I will answer you in English - faster for me since I do not have a Heb keyboard. If you need information in Hebrew, call me.

The plane has an official flying weight of 5.3lb. Make that into 5.5lb. At 150 nominal watts and 80% efficiency rating, you want 1KW input power.

I suggest running on 5S or 6S, to keep current reasonable.

You will need to modify the plane to accept a battery tray easily.
