    if you read the Q&A the seller gives that link I posted above to program it.

      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.

        I thought it said it doesnt need to be programmed. Not that its not programmable. Either way it doesnt need it. just plug it in and its fine.

          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.

          had to drill prop hub for larger shaft. just went for it on the hand drill. balanced out just fine.

                  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.

                        Regarding using LiFe packs , I like that idea. After all, that's what I use in my transmitters. And, as for the "keep it simple" part, I'm trying. Unfortunately, as for the "afternoon build" part, that's not possible.

                        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.
