3D Printed RS850

Built a new RG65 hull. Reused the rigging and electronics. Very handy being able to take the servos out as an assembly. The colour of the first one was a bit too dark against the water and it had a leak that I couldn't solve. Very happy with number 2.  Cheers.

This is the upcoming RS850 design. It has some very unique experimental features. A very long keel with a lighter bulb. A twin mast stayless rig. A stern hung rudder. So far test sailing, she is performing very nicely. Tracking upwind is hands off and acceleration is amazing. There is more testing and refinement to be done but so far it's performing very well indeed!

I always build two . . . for match racing.

The boat handles magnificently with a very neutral helm.   She accelerated in the puffs, rather than rounding up. What a joy to sail!

Here is my finished RG65. It was very satisfying to build and sails great. Printed perfectly on my Bambu Lab A1.

Just wanted to thank you for the free download plans and for the 3d printed version I purchased from you. I built the green one out of balsa and plywood. Printed a bulb for it.  The blue one is the 3d printed one.  Both were covered with 48gram glass cloth and painted with 2k paint.  Sails from 100% polyester shower curtain.

This is a new boat currently in the design phase at Racing Sparrow. It features several unique design elements, including a twin-mast sail plan, a stern-hung rudder, and an extra-long keel. The design is centred around a 1000mm main mast, a common and inexpensive length of carbon tube. The materials and electronics required are kept to a minimum, with no stays, goosenecks, or rudder connectors.
