Once you figure out how to seal the hatch covers they make a nice light wind boat. Sadly, they leak so severely the boat is very likely to take on enough water to damage the electronics and/or cause the boat to sink.
This is well known to those of us that have one. Another tip is having a "b" set of sails will expand the boats range of wind conditions it can be sailed in.
Another consideration is these boats make terrific display models. They have lots of scale details and don't take up much desk or shelf space. I keep mind in my office on top of a filing cabinet.

I posted a few videos to illustrate why it's so important to seal the hatch covers. If you don't address this issue you'll be very unhappy! The last video is from Stockmaritime in Germany. They offer a version of this boat with a number of custom features that make it a very special boat.

Great points, thanks! I just took delivery of mine and am about to try her on the lake.
with a NiMH 5 cell battery inside, she leans slightly to the stern. Is this intentional? Not sure if it happens with the regular 4 cell AA batts too.

Well if it bothers you try the 4 pack to see the difference. The biggest issue this boat has is the hatch leaks. Once that is resolved I don't see a major issue with your boat's handling with the larger battery pack. If you watched the video below you can see the boat has a Go-pro camera mounted in the aft end of the boat and it still sails - a bit like a submarine but it still sails. Try both ways to be sure. Enjoy.

Thanks. Blew the sail winch servo even before putting her in the water! Going to replace with a purpose built servo. Kyosho is just using a std servo here...

I am looking into this boat. What are your thoughts now that is has been a few years? I want something simple and ready to use for a large pool. How do you seal the hatch covers?

Boaters are nice people.

The 'ready to use' is the problem with this boat, even after a few years; a new boat will still leak badly and if the large pool is chlorined, the lifespan of the electronics is reduced drastically if you don't waterproof them prior(!) to getting the boat wet for the first time.

The boat looks stunning; a few years back a guy showed up at a Micro Magic practice day with his Fortune.
After a few laps around the markers he had been lapped several times by the entire field and finally had to be rescued with failing electronics due to (a lot of) water ingress.

If you can find a RTR Graupner Micro Magic (new or used) I'd go for that boat.

Regards, Jan.

What do you do to waterproof the electronics from chlorine?

I posted pictures of the underside of the hatches and of their respective openings to illustrate the problem. Sealing these hatches can be done but it takes some imagination. The boat is very small and the space to install sealing foam is very small. The small front hatch is held in place by to SS snap devises that provide little if any resistance to water intrusion. The lip around the opening is not much help either. The rear hatch opening is ringed with a very thin layer of foam or felt which is more like a dust barrier than a water tight seal.
The rear hatch is an easy fix - replacing the OEM seal with a good grade of dense foam - using the beam that goes across the opening to install fasteners to apply downward pressure to the new gasket you could get a pretty decent seal. The front hatch will take a little more thought to come up with a way apply a gasket and then to secure the hatch well enough to create a good seal. The SS snaps are no up to the task.
