Ideal mast is the NS drop-shape. But you should be able to use an RDM with some ok results. Is it a North RDM?
You will need to use two large spacers on the bottom two cams, and one spacer on the top two cams. Add loads of tension to the bottom two battens, medium tension to the next batten and neutral tension to the last batten. This will give you max power and stability.
For max top-end speed, downhaul about 1 or 2 cm past the VTS dot. This will allow the leech to twist/exhaust power to get higher speeds (much higher speeds). It will also feel much lighter in the hands and you will be able to take it out in much stronger winds to gain extra KPH
. Cams will be harder to rotate, but they will pop around 20 meters or so into the new tack.
Dont worry about the lack of profile, all past and current Warps, Daytona's and Rams set flat c/w over race sails. The profile is more gradual than others and the power comes from further back in sail. If you dont like speeding on the fin, you may need to move the mast base forward 1 or 2cm more than normal.
Hope this helps
