Does anyone know if v276 will work on the RSX? and if not where I can download v272.I have one that shows v258 installed and is the latest version avalible

The latest version doesn't support any update to the RSX or any Gen2 esc's. You can still adjust but no more firmware updates will be released for the RSX. I do have hotwire V13.4.1 that has the last update for the RSX. I always keep my old versions of hotwire so just let me know what you want. If anyone has better information please correct me.

In sensorless mode does the Rsx use back emf to commutate the rotor?

Yes.

Thanks

Interested to purchased RS Pro black edition for stock racing how would you like compared to HW XR10 PRO G2

RSpro has the lowest resistance for Spec racing and what it was specifically designed for. For mod racing you need the RSXpro because it has a heatsink and a fan.

someone school me here...
RSX vs RSX PRO (im guessing the former "cheaper" by $30 is an older version?)

does it matter for an xb4 10.5 build? if its worth the extra $30...im not gonna complain.

hard to find the info on google, found it here...so nevermind
New solder posts that are shorter and have a different solder pocket design for easier connections.
New FETs which upped the amperage to 210 from the previous 180.
New BEC components.
Board composition also changed, striving for lower resistance.
Larger heat sink for increased cooling.

The RSX is no longer produced or supported with software updates. Any you find for sale are old stock. Go with the RSX Pro.

Thinking to get my first Tekin RS PRO BE or R1 super stock LCG can't decide. Any pros and cons RS pro BE i run only stock

I see no stock of RSX Pro anywhere, is there a bit of a shortage to find new ones?

check tower hobbies

No stock either.

Is there a way to extract the raw data from Hotwire. I know we can download and view the files through the Hotwire tool, but I want to extract the raw data points and put it into a more typical full scale data analysis program. I would love to be able to pinpoint three different sections of the track based on throttle lift points then view average mph or rpm for each section. Would also then be able to find best theoretical lap by looking at the best of the three sections.

I love the idea of the Hotwire, but wish it could capture more inputs and download the raw data sets.

Export Run data gives it to you in a CSV file so you can see and manipulate the raw data. Save Data creates a file you can open and view in the graphs.
