New main Radial or tape drive...?
Thank you for your information, I will look also at North 3Dl. I know need some information on the radial sails...since it looks that the tape drive do their workand the price is reasonable. The idea is to use the sail mainly for my aficionado races....but who knows ! Well what about radial sails !
On the E question that was my concern....not to play with designs , for that reason I send my questions to the designers Rob Humpreys and wait for their answer. When I asked for the polars it took .....about 3 hours , great ! letīs see if they are as helpful as before.
Well thank you for your help.
