The following is a product overview of the Heliup Carbon Fin set.
These fins are a one for one swap with the stock fins and are pre-drilled
to accept the same screws and mounting position as the fins they are replacing.
They are made from 1mm carbon fibre sheet and as such have good tensile
strength. As they are 1mm thick there is a fair degree of lateral bend
in the fins, particularly the long vertical fin.
In use the vertical fin provides ample protection from ground strike of
the tail rotor. Neither fin presents much of a surface area to the wind
and as such weather cocking of the tail is less of a problem for 3D pilots.
Both fins are nicely made, well cut and strong enough for purpose.
