After my Robbe Unlimited burned out, i wanted to have a good boat that could replace that one. Peter of 2 Brothers RC did know which boat i wanted, one that was fast. The choice was made. It was the Rain-X of Danvo. I let him know what i was planning to do with this boat, fast motor fed with a lot of cells. Soon some of the parts where replaced, like the rudder, the axle and the trim plates.


For the prop we initially chose a 36mm one, but after the first run last sail day we replaced that one with a 33mm. After 2 days building it was finally finished. Happy as i was i took it with me to the last sail day of this year, for a run. After putting it in the water, i gave it full throttle, followed by a moment of silence all around. This boat goes like....(no decent words for it)... fast! I was just as happy as a kid. Wow, this was great. But after the boat turned on his back, because it was very nervous at full speed, we made some changes; it still was nervous, but was a bit more stable.

Now we improved the boat wit 2 turn finns, and extra trimplates, so it wil run better. We did have a first run with the boat, and indeed the boat did runnig a lot better. Only after a couple of rounds the 700 motor burnt out. (we just did a speed trail 44.7 Km/h) We think that the motor was run on too high a voltage (20 cells), and that that was the reason why it burnt out.

We now placed an 820 BB turbo motor in it, and water cooled it, and hope this one won't burn up. I think the boat is now too heavy, because the topspeed is lower than with the 700. Last we did a speed trail with our own GPS, and the boat didn't run faster than 36.4 Km/h. Now thinking to replace this motor with a 700 motor again, only now a 12v one, instead of a 9.6v. Maybe that will increase the speed to about 50.

(Sadly, the boat crashed into a quay wall, and a large part of the hull was cracked open. I couldn't repair it, so it's RIP)
