The Nirvana, manufactured by Megatech and distributed in kit form through hobby stores worldwide was designed from scratch to be a nice looking, high performance, RC model. The goal was to get a fully equipped, ready-to-sail boat designed and produced at around $200. The sloop rig features the high aspect rigs of the time, with a deep fin keel ballasted with a lead bulb. Her carbon fiber reinforced hollow, spars are extremely strong and attractive. The mast is even tapered, a feature not previously seen in such an inexpensive boat. Her sails are polyester (mylar), and are extremely strong (will not tear or stretch), water resistent (will not mildew), and she is well fitted with all needed adjustments.
One of the unique features of the boat is her electronics compartment. Hidden under a deck cover is a snap on hatch reminiscent of the RC Laser. The boat is molded in one piece of ABS plastic. Even the electronics compartment is fit into a well molded into the deck . So the electronics are not really inside the boat, but cleverly mounted in a sealed box . This clever design keeps the electronics dry and easily accessible.
Her hull design features an interesting "bustle" that allows this small boat to carry her weight well aft. The result is a boat that keeps her nose above water when reaching or running in a blow. There are other features on the boat that are rarely seen on small boats, like pin hole adjustment of sheet lengths on the booms. She has a balanced rudder design that allows for quick response without slowing her down, and the single adjustment for both wire shrouds makes for fast and easy set up.
The racing rule is very strict but does allow for a number of improvements to the boat to make her easier to maintain, and more durable for all out racing. Nothing is allowed that will improve her performance. As of July 2008, there ware already 483 boats registered and numbered in this booming class.
The RC Nirvana is an international One-Design class regulated by the class to insure strict performance uniformity worldwide.
NIRVANA Class Rules
This class one-design racing rule is designed to establish uniformity in the Nirvana class on all features that affect boat speed. Any modifications to the standard manufactured boat must be approved in this rule.
The rule with the attached Modifications/Clarifications is in its "muddy" stage as we develop the authorized modifications and note them, so bare with the dated changes. When we have gotten a good handle on the final rule, the entire rule will be rewritten to incorporate authorized modification/clarifications in a simple to read document.
For the time being, please understand that the "concept" is the driving force. The class races the boat "as manufactured" with authorization for modifications in writing here as the only means the boat can be modified. The idea is to prevent any modifications that will allow the boat to sail through the water faster. We want to have races won by sailors that sail better, not those with a faster boat.
In that respect, one last word. "You can't win if you don't finish!" Many of these authorized modifications are designed to increase durability of the manufactured boat, and to make it easier to maintain. Those are the kinds of modifications most likely to show up as "authorized".
The RC Nirvana is an international One-Design class regulated by the builder to insure strict performance uniformity worldwide.
