Nice work..
I started building a chassis dyno as well, and with a heavy roller, then my esc died during testing because it was too heavy.
Then I switched to a flywheel design, and found the results are better as you remove slipping that could occur because of tires, and I added a pololu servor controller. This controls the throttle and ensures repeatable results.
I see that you only have the roller reading. For power runs, you will need a current sensor and voltage sensor. For voltage, I built a simple voltage divider and connect it straight to the arduino. Just make sure that your voltage divider does not output more than 5 volts, as you will end up with a dead arduino board.

this is the new race one. It's the only 160amp 1/10 scale one they make.
I use it in both my offroad cars great esc. Not sure where you can get one in new Zealand

I finally got to run my 17.5T in my 2wd buggy and i'm impressed. A guy at the club set the timing to 6amps (51deg) and using the same gearing as with my old motor it was noticably faster and came off cool. I've ordered a couple of bigger pinions.

I have another 17.5T which I will put in my 4wd buggy now. I'm currently running an Orca Blitreme but while its fast enough its running so close to the line to keep up with others and has been cooked when my fan got broken. I'm impressed so far

all the people that run them at my track including my self they all run cool for us. I will be making a website to sell them on because I was flagged for selling them on here. Even though I am not a company. I will keep you all posted. If you like to see your cars featured on a website. PM me some pics. Looking for some cool pics of cars jumping whipping and sending it

That speedo looks a lot like a Fantom one and the specs are suspiciosuly similar too. I still haven't found one here so ended up ordering a SkyRC TS120 as the price was right. I had a few unexpected things this weekend as a few things failed. ESC and battery being the expensive things plus some other little things, including new pinions for my now undergeared 2wd buggy.

I'll keep looking for the Surpass speedo though, they are intriguing

I I have been running the surpass rocket v4s red version 13.5 motor. I race Expert 13.5 4wd at SDRC in San Diego. I have been super happy with this motor. I had the R1 V16 prior to the Surpass. It is comparable. As for the numbers above, I know you are unhappy with the RPM, give it a couple days and RPMs will come up from what I have seen with my motor. The first couple days it had enormous torque with not alot of top-end but now, I'm not sure if it needed to loosen up, but the RPM and top speed increased with about a week of racing. Super happy with it. I am running against the tekin spec r, R1 V16 and v21, and every other motor. Other Racers have driven my car and think it is super fast. They are surprised to know it is a surpass rocket.
FYI... I believe it is one of Nick Adams videos states the Fantom is made by surpass. Don't quote me but I believe that's what I he said. There are two videos that Nick Adams did with the surpass, not one. This is why the Fantom motor is boxed and looks nearly identical and I believe the ESC, someone said, looks the same... with the same specs. I believe Fantom is made by surpass... But not 100%... Per what I believe Nick Adams said.

Phantom compared to Surpass Rocket. Watch Nick Adams video on the V3 blue Surpass Rocket. This is where he compares it to the phantom motor. Same boxing, same specs and a few other things. Watch the video and he explains it. Surpass does make other motors for other companies. I am sure this is why the Surpass ESC looks similar to The phantom ESC.

what would you like to know about them?

Are they similar to the hobbywing with the throttle, brake frequencies and data logging? I am in search of getting one or two new esc's, I have the 17.5 motor and love it..

They use a program box. As far as the settings they are to me just like any other program box. There is a way to hook them to a pc but I have not done it. I have no need to. I ca. Get the feel I want just from the program box
