We have noticed two minor issues with the Extension kit.
The M2.5 nyloc nut for the torque tube splines was inadvertently replaced at the factory by an standard M3 nut.
Because the new boom supports require standoffs an M4x30mm bolt was incorrectly specified. The bolt needs to be a M4x25mm. The standoff is correct.
Charley is bringing parts back with him to fix this. In the meantime, please contact ReadyHeli's RMA department if you are confronted with this issue. There is a good chance many extension kits are affected. Our most sincere apologies
This is straight from Scott, he mentioned this on another forum, and we wanted it here as well.
