"Altered doesn't comply with the 6.5 kg tip weight rule either. That was undoable.

he had to put 2 kg in the very top of his mast and as such his moment of enertia would come out at more than the AHPC superwing mast."

It is correct that Altered's mast is under 6.5kg. tip weight. After gluing cedar in crossways of aprox. 1kg per 1.5 metres from the spinnaker point down to the base, I ended up with a 6kg tip weight but was perfectly willing to add a .5kg corrector to the tip.

It would be possible to bring the Stealth masts up to 6.5kg by adding a corrector. But what would it achieve certainly not a increase in strength. As for the Aussie Taipan percieved problem I believe they are already above 6.5kg tip weight is that correct, I am sure you have weighed your masts wanting to be competitive in F16 and all.

I still am unsure on this change it is a big reduction either going to 5.5kg. or losing it completly. Maybe 6kg. would be a better minimum.
