Hi all, Just finished an RG65 racing Sparrow. (I made an 80% size one a while ago, it's in the gallery).
Standard hull with 1 layer of 50g glass and epoxy. Deck is 1.5mm balsa with veneer strips on top. Single hatch with rubber seals and 3 hold down screws.as I fitted the rudder servo into the recessed rear deck. Corona servos DS339HV digital for the sails and CS939 analogue for the rudder, I fitted a greased cork gasket under the rudder servo arm to waterproof the servo. Battery is a 2S 1000mAh lipo with a regulator for the Rx and rudder servo. Radio is Flysky CT6B. laminated ply fin with 2 layers of 50g glass, rudder from balsa with 1 layer of glass. Ballast and fin is 680g. Mast is slightly taller at 1050 so the sails are slightly different to fit within the 2250cm max. All up weight is 1150g.
I'll get sailing pix very soon.

This looks absolutely stunning. I just love the deck work. It must have taken you ages. Your sails do not look like the normal film. Did you use something different for them?

I used the lightest ripstop fabric, about 8x8mm squares.

Today, Sat 31st it got wet. Gusty breeze up to about 12Knt max. Some trimming to do but it didn't take long to get into the groove. Holds course hands off and port / starboard tacks have 1 rudder trim click of difference. Initially I had the battery right forward in it's mount, and the boat was noticeably bow down, inclined to dip the bow when caught in a gust while running downhill. Moved the battery back by 35mm and it all came right.
Absolutely dry inside after having water running over the deck and hatch. The max heel was about 60*, I was on the water for about an hour.
The Corona DS339HV sail servo with 55mm double haul arm handled the sails perfectly. Plenty of power. ImageImageImage[url=http://img856.imageshack.us/i/u8f3.jpg/]ImageImageImageImageImage
