Title: Schooner Yacht America 1/85 scale
Post by: meatbomber on November 13, 2010, 11:06:59 AM
Hallo Shipmates,

Mark Steele a Collumnist for Duckworks e-zine and marine model international, has issued a challenge to seek the smallest RC Schooner on the planet. I like schooners and small RC models so i couldn`t pass on to this one ;) The model of choice for me was teh Schooner Yacht America of 1851. A relatively simpel rig and very very nice lines make this undoubtedly one of the best looking yachts ever to be built in my oppinion!

As the scale i selected 1/85 so she will fit to my small St. Helena packet. That made for a relatively "large" 36cm length on deck but the displacement is only about 250g which is borderline to whats possible, to handle the 7,1dmē of sail area.. at least for me  :o

All sails sheets run of a single servo. There is a 200mAh 2S Lipo for power and a BEC to run the servo and RX. space below decks is at a preminum... The sail servo is a relatively strong HS82MG that i hope will provide sufficient torque to sheet the sails.

Sails are made from ripstop material, a first for me, working with a hot knife and textile glue. The results are pretty satisfactory in my eyes ;) there is still some detailing to be done tho... the Gaff halyards are bowsie adjustable so i could later one with teh addition of reeflines make fore and mainsail reefable.

With a plexiglas keel of 25cm length and about 100g of ballast i went for the first sea trials :) unfortunately absolutely ZERO wind... it was howling storm the whole day, and wind warnings for the night but exactly at teh hour i have had time to go to teh lake a total calm.
But at least i saw that she has no leaks, the rudder provides sculling power and the trim is correct... i hope to have a proper sail report soon !

Had the REAL maiden today :) this time wind from SW by W 5kts gusts 10kts.
Put her in teh water and she took of, straight as an arrow close hauled. Ballance is near perfect. so perfect in fact that she won`t tack... i could wear anytime and in any direction (even towards the main boom in gusts) so it can`t be the rudder being too small. Else she is running great, weatherly, fast and looking great on the water :)
so now i need some advice as to how change the configuration to enable tacking. maybe the keel a bit forward ?

I set the keel further forward by a total of about 2,5cm. Tacking now works much better! I had Zephers only but America at only 250g reacts to the lightest stir :)
I hope for another sail with a bit more wind but i doubt this year.. now its -10° so i fear after tonigth the ponds will be frozen...
