Sail Tuning...

Just wondering if there is a thread somewhere that discusses sail tuning, especially for different wind conditions.

As noted, last week I forgot to trim in the jib so it was very loose during the Wednesday races. I'll tighten it up for the races tomorrow but any other hints would be appreciated.

Thanks, Bob/Bradenton

^ Thank You for that link full of knowledge. I have been studying full-scale sailing because I could not find these finer details regarding rc boats.

Nirvana Tips


Sailor Bob,
This is a compilation of information I recommend for making your Nirvana bullet proof(?????) and some tuning tips from the SailRC web site.
The re-rigging of the Jib and Shroud to eliminate the load on the mast tang is highly advised. The jib load on the tang in winds above 15mph has a tendency has a tendency to break the tang. The common servo replacement I use for sail is a Hitec HS-645 and for the rudder a Hitec HS-311.

These are just my suggestions based on sailing the Nirvana on average 150 to 200 hours a year for the past 4 years.
The Nirvana is great boat and a lot of fun.
Happy sailing,
gvank

PS: You can check my posts on this thread for more information.

A Nirvana is up for auction on the ShopGoodWill.com website:

https://www.shopgoodwill.com/Item/49269632

Be sure to check the Frt/Handling charges. I was going to bid on it but the shipping from MN to FL is $30. Not enough margin to gamble with missing parts. Note that this may be an incomplete boat. Box was certainly opened and looks like the boat was used at some point, so bid accordingly.

One day to go (from 2/20/18) so maybe if you are interested, send that GW location and email to check for sails, etc. Don't expect a reply or for them to know what a "sail" is.

I buy a lot of stuff from ShopGoodWill. Mainly original artwork but if you are careful (for example them overcharging for frt) you can get some really good deals there.

Works sort of like Ebay. Bidding ends at a set time, and yes, you can snipe. Do it all the time.

Thanks for the great Nirvana tuning/set-up info.

PS: Did great last weekend sailing. Everything worked...

This isn't a Nirvana post but I've got one of these really nicely built 29" wooden ChrisCraft RC boats and one just came up on ShopGoodWill.com. It's a pick-up only and it's out in Sacramento, CA, 4 days left on the bidding so if you have any pals out that way who can pick it up for you, these boats are really cool.

Demos are on YouTube too. Fast or classically slow and have a sound effects generator for a motor sound. (Although it does sound like a 2-cycle engine or a hot Mazda Rotary).

Here's the link:

A great tender to the Nirvana regatta's especially when equipped with a mini-camera to record the races. (We also "equipped" ours with a Barbie Doll in a bikini!)

pointing


Boat will not point anywhere close to what other boats can, where do I look to correct this?

Can you post a few photos of your boat's rigging set up and of it under way - like to see the sail's shape under way. I posted a of picture of mine boat for comparison. Not had any issues with it's handling. I have made very minor mods to the sail trim set up, that was just a personal taste thing.
Are you getting full sail extension?
Years ago we found these boats like a like added weight improved the boats handling. Have to look back through the thread to find those notes. Didn't take much but made a positive difference. See the picture below.

seabee,

Check Post # 11419. I assume your boat is fast since you don't mention having any issues other than pointing. If your boom C/L is pointed at the shroud the boat should point reasonably well. I would suggest a boom adjustment as follows; inside edge of boom to shroud or outside edge of boom to shroud. Check the point at each position. One will help the other will hurt. On the side that helps, increase the slot slightly more (open or close), until the performance falls off. Then back up to the optimum position for "your" boat. I find that the slot opening is critical to maximum pointing ability when the boat is properly balanced and sailing well in all other aspects.

If you are sailing a Nirvana II with pin hole adjusters you may have to drill more holes between the original holes. The Nirvana III with "sliders" for adjustment is easier to tune. It doesn't take much adjustment of the slot to make a big improvement in pointing ability. Remember, the nominal position or slot is pointing the boom C/L at the shroud with the main over the toe rail break at the stern.

Just my opinion,
gvank

Thank you to Boomer and gvank, I believe the slot size is my problem and will know for sure when I get back on the water. I have to re sheet or drill another hole in jib boom.

What happened to Megatech


I have tried unsuccessfully to contact Megatech about my Nirvana II rc sailboat. It appears the company is no longer in business. They have a website. The phone number in the website is not a working number. Their email address is not valid.
I am having problems with the boat and can't find any Megatech support.
