great throttle response and was able to clear doubles without any issues coming out of 180 deg. hairpins. this esc actually has a smooth power band that is helpful with a 2wd truck.

I'd love to know your settings.
vehicle, gearing, motor timing, boost timing, rpms, etc.

Thanks!

This is in my 4x4 but I think it's the same thing...sorta...kinda

Yeah that is close. My only prob is height for the Buggy Body and with the longer 1/8 motor in there is it a tight squeeze. Thank You!!!

If anyone else has a buggy mounted up let me know or see? Gonna measure my vtx8 height and a Gen2 RX8 to see if they are the same.

Just wanted to note on the discussion of the neutral signal. The issue comes from how the signal is coming from the radio. The speed control only can operate by what it receives from the radio. The difference in the signal and how it hold a neutral point are dependent on the radio. Our system will not engage if it can not find neutral. Other systems will engage, but if you ever hear someone say they "lost" brakes during a race, or didn't think they got full throttle -- that is the neutral point moving. If you have ProGauge, you can actually go and measure the end points on each model of your radio and see how they are a little different. You can PM and I will send you the link with the steps.

As for cut offs. There are really 3 types. 1)Protection - temp either motor or esc == in which you would see an error code on the VPort. 2) Low Voltage cut off. If this occurs the system will cut off and reset about 10 seconds later - after it goes through the start up sequence. This can be because of a voltage spike (caused by crash, settings, or just inefficient motor) or the battery not able to handle that spike. 3) if the system shuts off and will not turn back on - there could be multiple reasons from poor connection, internal failure, connection inside battery. These are harder to figure out.

Haven't messed with the neutral settings just yet but thanks for the call to get my esc back on the road again... I think I have most of it figured out now :sweat:

Start with profile 2. Make sure you are on a55 software. If you aren't get updated to it. As far as gearing goes, that depends on the car. AE and Kyosho cars are typically 23/81 for 8.5. TLR would be 22/78.
