The stabiliser moves the centre of lift forward, and increases the leverage on the bolts. Without the stabiliser, the centre of lift moves back - closer to the bolts, so the force on the bolts of the fuselage to mast reduces. The leverage at the mast/board attachment also reduces if the stabiliser is removed.fun2kite wrote: ↑Mon Dec 24, 2018 4:27 amHey Sergio,
You recommend just forget to attach the stab.
I have a question about the leverage force created by removing the stab on the fuselage bolts: I have Onda, so what happens to the forces applied to the screws that hold fuselage to the mast? what happens to the inserts?.
I understand that the stab provides the force opposite the one one created by the front wing.. (ie: front wing pushes up and stab pushes down). So both screws attaching the fuselage are probably almost equally loaded? but when you remove the stab, the lift increases and so the front screw now handles all the twisting pressure coming from the front wing and back insert experiences the screw being pulled out of the insert? Basically, what I am asking is: Will the imbalance created by removing the back stab on a from wing like Onda ruin the inserts and damage the mast eventually?
Onda Wing sits quite far forward from the mast. Unlike the front wings you guys ride. The leverage is therefore much larger to pull the inserts out. .

No not yet, but more and more people ask me, while finding out is so easy, just forget to mount your stab. But I have no doupts a 1200 cm² Wing especially with the shape of the Onda has to be easy, look at the video from Øyvind what is possible, would espect the ketos and moses 1200 cm² mono are on a similar level for mono.
