One day not so long ago I managed to take a few pictures of the Fortune 612 on the water. Here they are. I hope you will enjoy as much as I do.

Today I brought the Fortune to the model boat pond to test it out. After one of my cats had broken some of the rigging I had to learn how to tie knots that wouldn't slip so I could fix the rigging. So far I am very happy about the modifications I have done. The rudder end keel keeps this boat upright and under control. I could even keep up with another modified Fortune.
The modified electronics also worked very well. I don't think I ever lost the radio link and the sails were under control. The telemetry told me the voltage of the battery in the boat.
The thing that brought me in was the battery in the transmitter...
Talking with one of the other modellers at the pond I had a new idea for modifying the electronics: Add a sub micro steering servo for the rudder and keep the two main servos. The front servo will control the front sail and the rear main servo will control the main sail. That should give me twice as much power to pull the sails and give me the ability to trim the sails individually.

I wasn't satisfied with the RC installation in the Fortune. For this reason I decided to play around with it and see what I could do. For one thing I didn't like the 4 AA batteries. I would like to run on a 2S LiPo. Furthermore I would like to have a high quality servo controlling the sails. When I found the HiTec HS-5646WP I decided to try those for both rudder and sail.
Furthermore I had an extra Futaba R7003SB receiver I didn't use. Using that allows me to monitor the voltage on the battery as I can monitor the receiver voltage without. I had some issues with reconfiguring the s-bus channel so I ended using the two other channels on the receiver. Fortunately the transmitter allows me to freely bind controls to channels.
I also decided I would change the lay-out of the installation. For that I would need a different battery tray. I designed one on openSCAD and had a friend of mine 3D print it. He printed it in both one and two pieces. I couldn't make the two part battery tray stick together so I ended up using the one part print.
Here are some pictures of it:

After waiting some time I finally got my last 40 year birthday present: A Kyosho Fortune 612 III. Quite easy to put together and in my mind a very good looking boat. So far I have sailed it twice. It seems that I'll need some practice to become good at sailing her but so far I have enjoyed it. I have had one issue though: One of the wires would become trapped in the details, meaning I couldn't control the sail. So now I have mounted the crew to see if that solves the problem?
I have only done one modification so far: The receiver was replaced with a Spektrum MR200 so I can use the same transmitter that I usually use. Nothing wrong with the supplied receiver. I do have some ideas for modifications though
Some pictures of her. I hope you will enjoy her just as much as I do:
Thanks for looking
