I was set to finish my 42 cat this week but figured with the water getting colder, I need a rescue boat. The last few days have been long days/nights in the shed constructing this thing that still need's a little work to achieve my end goal for this vessel. As a rescue boat for rc's it does the job well but after my first test run I realised that it's floatation and size make it a very versitile water craft that when running right I have a few things in mind.

The set up is a castle 1717 1580kv motor with a turnigy 180 amp speedo that I added the large etti cap bank to cater for the extended battery box leads. I've made two battery box's that each hold 2x 4s 5000mAh Nano-tech's and the wire's have been soldered up for ease of use and safety. To turn the motor I'm using a hitec servo and the electronic's are controlled by a spektrum receiver and transmitter.
My first prop choice was an octura x447/3 and it popped onto a plan on take off but snapped the flex shaft and scared me off that size prop and I went back to a thinner 2 blade prop to take the load off, this craft is heavy. After a few more runs and prop changes I ended the day thinking I had the best result's with a m447 and back to the x447/3 realising that I must have stuffed that shaft when I ran the stilleto in reverse to see how she'd go, I burried the boat and it didn't run right after that.lol. Most my video footage was done by myself so I had to drive one handed so it's a little tame but I can tell you that she dances and bounces around up on a plane when driving with two hands and a heavy finger, good footage will come. The electronic's are up to the job but the vessel need's a little work, temperatures didn't come into at all, no issues there. The front sponson's need to be lowered to help get the main deck out of the water, I'll try over the weekend and see how it goes. I'm thinking this thing will be capable of around 30-40mph once I find the correct cog and prop.
Any advise is more than welcome
