Re: Checkstay - lower shroud
A mast strut has fallen out of fashion since the raised foredeck and the advent of the mast ram. On a flat deck and deck stepped mast, a mast strut was used to brace the lower section of the mast to resist the forces of the goose neck (same function as a ram).

Distance between marks
I would know a reference distance between marks in the races (triangular and trapezoidal) or a medium time to do the races.
Someone can help me?

Hi Don
Unhappy I do not have. Would be interesting if we could have. If someone has a table of offsets and want know resistance by Michelet, inclined waterlines, Turner's Moments, righting arm and accept make the results available for all I can do the work.

Seeing the IOM Hull Depth gauge v.3R I understand that a boat whith DWL 1.00 m can have a depth more than 60 mm. You d'ont see this in the figure? If I put a hull with 1.00 m DWL in the gauge the botton of the boat stop in the stern and bow support before the real DWL is in. I see this. I must be wr...

I have some conclusions about the LiFePO4. Today I receive a e-mail from Bruce Simpson (RCModelreviews.com) about the supply of 6.7V or a bit more to servos Hitec. He says that he used 2 LiFePO4 cells in a range of Hitec servos since HS425BB through to the HS5955TG without any problem. With JR servo...
