Admittedly, I'm probably just as confused as you are. On the product page, it states it's not programmable. In the 'Qs & As', it also states it's not programmable. Yet, according to the PDF, it (supposedly) is programmable. Just not sure which (PDF, or product info and 'Qs & As') is accurate.

new motor arrived. she is now a beast in the water even on 3s. literally had to turn the throttle down to 70%. motor stays ice cold now also. 3536 1250kv with 10x6 prop.

Got a link for the new motor?

so I found a highly valuable secondary use for the rescue boat. That is clearing sticks out of the pond. I made this net on the back to help catch sticks and bring them to shore.

I also widened the boat to 24" for my new project as well as to make it easier to get on any boat at 50-100 yards out in the water.
new project - massive hull for me (42" x 16" wide)

I still like the rescue platform design I came up with...and, I also still like the design you came up with...but, I felt there was something "wrong" with my design. So, I've completely scrapped my design, and will be working on a different design. However, I have decided on the "base" of the design. Instead of using PVC pipe & pool noodle, I came up with the idea of using an RC plane float set.
The floats are styrofoam, so I am thinking of covering the foam with a thin layer of fiberglass, or just resin. I'm undecided on 'which', as I've never done either...any suggestions/recommendations? As for 'how' to mount the electronics box above the water, I've got an idea, but first need to find out if I can get a certain part from the float set manufacturer. Your rescue platform has really helped me to start "turning my brain's wheels".
Regarding the "new boat project", is that a Fighter Cat?

its an aeromarine sprintcat. Its been done for months now with a TP 5670 motor. today ironically I think I got it fully sorted out for good and lapping steadily over 60mph.
This feels like forever ago. I have used and still use the rescue boat 2-4 times a week, its a hit at the club and saves so much rowing. it has rescued at least 150 boats by now. today alone it did about 5 boats some of which were 100 yards away.
keep it simple. this should be an afternoon build. one thing that couldnt hurt is to use a lifepo4 battery. like a 4-6ah. high winds can really put a damper on the light boat and you wouldnt have to storage charge every time you use the boat. make it wide as it get difficult when rescuing a boat far away. it takes practice to use these things.Comment

For starters, the float set is Styrofoam, so I will need to hard-cover them. That, alone, will be a 2-day process. Initially, I was thinking fiberglass...but, the weight could end up more than expected. Plus, working with fiberglass isn't something I'm interested in trying...at least, not yet. Instead, I'm now thinking a colored epoxy resin. Two coats should be good. The only 'problem' I'm running into (in my searching) is determining which are "Styrofoam safe". I believe all polyester resins are NOT "Styrofoam safe", and all epoxy resin IS "Styrofoam safe"...but, I'm not 100% certain.
Once the floats are finished, the rest of the build should easily be completed in a single day. The third/final step could take a little time, considering the 'interesting'...or 'strange', depending on how one looks at it...idea I've come up with for steering. I will test the idea before building the platform, as I'm not even sure it's possible...but, here's the general idea:
In traditional RCs, steering is done with servos, via Ch1. Tank mixing is done using 2 motors/ESCs, typically on Ch2 & any other available channel (ex. Ch3). I could just go with tank mixing, as I have seen a couple others do, and remove the float's pre-installed rudders. But, since the float set has pre-installed rudders & servos, I might as will use them, right? The down side is that the servos aren't very strong, and I might not be able to replace them with stronger ones. But, if I could, simultaneously, use the rudders AND tank mixing for steering, that would a) make turning the platform so much easier, and it could (potentially) turn sharper; and b) require less effort from the electronics to steer the platform.
