Status: offline 		Hello Fabio,

Nice test. But raise your left foot from the ground so that the wing really gets 90kg and wide up the distance between the tips...

How do you build up the wings ?

If it is only foam core + 1.5mm balsa sheeting you should get wings of around 360 grams.

What do you mean with bajonett ?


Best regards,

Mario

Come on now, I realise the US is not metric, but this is simple arithmetic!

Italy is metric? His title equates 90 kg to 40 lbs.

Normal conversion rate is 2.2 lbs to the Kg

Converting 75g/dM to oz/ft^2 is more difficult.

Hello Mario,
Fabio don't use balsa (expensive.. ) but he use "Impiallacciatura" ...i don't know traslate in english.
However, I think that the wing does not break
