Question

1st land sailer - Screaming Reach


Hello, this is my first post in the Sailboat section of RC Groups. I normally spend most of the time in the Sailplane section but I thought I'd try something different that has a wing.

I'll be building this bit by bit so expect updated here-and-there.

Below are photos of the basic frame-up. I need to stop by the hardware store and pick up the metal bits. Then a stop to the local Cabelas for 130# leader for the stays. I'm building per plans.

The plans suggest a sail servo (or high torque normal ) with minimum of 150oz torque. Any suggestions?

Thanks in advance.

Jeff

Useful Idiot
If 90 rotation is enough the GWS S04 seems to have a good torque/price ratio.

Welcome to the world of truly fast sailing, Sloperut. I've long thought that flyers should have a natural affinity for these things. I'm glad to see a report about this design, as it appeared to be well thought out. Is he still selling the plans?

I've had good performance with the Futaba S3802

Hi Bill, thanks for the greeting. Unfortunatly, Vexa controls does not sell plans anymore and all the info has been removed from the web page.

Martin, thanks for the advice on the GWS servo.

Doom,
There are some free plans of French origin to be found at the IRCSSA Yahoo forum in the "Files" section. You need to sign on to Yahoo to access them.
http://groups.yahoo.com/group/IRCSSA/
These are the same plans being used by War Bird Radio on this forum at :

I think a simple mast with a sail is a better way to go than building a wing
on a first build.

Also, I've been selling plans for my K1 model on eBay at http://tinyurl.com/2lqa7r , with a build log at http://www.rcsailing.net/forum1/blog.php?u=1049

Or build one of your own design, these things can be done pretty simply.

I use a 5/16" thick walled aluminum tube for an axle & it can be modified for either wheels or ice runners. Foam airplane wheels (Dave Brown) work great on pavement. I've found inline skate wheels too hard & tend to side slip when windy. If you try them, go for the lowest "durometer" rating you can find, as they will be softer & grip better. There's an entire discussion about wheels at

Not to be rude, but if you're looking for a high torque servo I have a Futaba S3801 here that I don't need, and I'd really appreciate if someone bought it.

It's never been used, still in the box with everything, and I'll give you it for $60.

Hi All , the S3801 sells for around the Aus$100.00 so it's a pretty good deal if you're in Australia .

Sorry mate , I don't need another servo at the moment.
