You will need to update to the latest Hotwire software: Tekin - HotWire 2.0 Programming Device

Done. Went to my local hobby shop/track for practice this evening. They had an adapter plug and did update my Hotwire on their computer! We then confirmed the change I made, using the buttons on the ESC, were the correct changes I wanted to make.

Using the current limit, did in fact help my lap times.

Just want to give a shout out to Jeremy from Tekin, for helping me with my Hotwire/computer issue! He got me up and running and was very patient with my lack of (tech) knowledge! Got all three of my RSX's updated and programmed like I wanted! Thanks again Jeremy and Tekin for great customer service!!

Nothing better than awesome tech and product support

The issue was not the Tekin product, rather my Dell computer. Had to open my computer in the safe mode to recognize the Tekin app. The local hobby shop had used my Hotwire on their computer and updated my mod buggy so I knew it was not an issue with the Hotwire. I wanted to make similar adjustments after returning from the track, to my 4wd and stock buggy. Anyway, thanks to Jeremy, it all works like I need now!


Lap times before the adjustments were 17.8....after 16.9!!! Yep....THANKS again Tekin!!!

Hi Guys,

I had a weird one with my rsx today, in my last two finals the negative wire came unsoldered from the battery plug while connected to the battery, the rsx was hot, but not hot to touch, and the motor was luke warm, as was the battery.

I run tc mod with a 5.0 on a shortish track

20 degrees on the motor
10 boost 5k - 30k
25 turbo - .5 delay and ramp is 2

I resoldered the wire back on for the last race and it did it again, at the 4:30 mark

I checked the datalog, and most of it was missing for todays meeting, like, only 3 minutes of 25 minutes of running.

only thing that happened was my r1 fan failed during the second run (the first time the wire came off) so I removed it from the car

from what little was there, the esc didn't go above 80 degrees F

have I damaged my rsx somehow ?

Whenever I have a solder joint come undone at a connector, I always replace the complete plug. It usually means something has oxidized or lost tension, so there's more resistance.

What kind of plug is it?

As for the data log, it only can hold so much. You can tell the RSX to record less info using hotwire and it will be able to record for longer, but to capture an entire event isn't feasible.

On a shorty track you maybe over timing the can with the gearing you're using. Wires coming unsoldered means a lot of amp draw so check to assure you're using at least 12 awg wire and good connections. You can try reducing the can timing and adding it back via the ESC for more control.

its a reedy 5mm banana with the spring cage, it is a bit loose as the plug last race day had fallen out.

I shall replace it and see how I go.

thanks for the idea!

Hi Randy

yes, I am using the tekin wire that came with the esc.

so if I took 10 off the motor and added 5 boost and 5 turbo ? or just 10 boost ?

thanks again!

Edwin

If the plug fell out, that's definitely the culprit. Those banana style plugs lose their tension fairly quickly. I suggest using the cageless style plugs that are more solid like these:
Tekin 4mm Hi Power Bullet Connector Set (3) Male And (3) Female

On a short track like that, I'd just do boost. Set the end rpm between 15,000 and 20,000 and the start rpm around 5,000.

thank you!

ill get some 5mm versions and try the different end rpm as well

thanks again!

Hi all, I recently bought a second hand SC5M which came with the RSX speedy. During my first race meet while getting ready for Q2 I turned on my TX and RX the truck was only steering. No throttle or brake however the ESC was recognising the signal due to the lights changing sequence in time with the throttle being pressed.
After about 60 sec the ESC would beep and the truck would start working normally. This was intermittent throughout the night and now its not working on throttle at all.
Checks completed so far:
* Changed Sensor cable - No change.
* Changed RX - No change.

Next I wanted to borrow a Hotwire 2 to update the software hoping htat might settle the issue.
Does anyone have any thoughts on whether its just stuffed or not.??
Cheers

Sounds like the RSX won't arm because it isn't seeing a clear enough neutral signal from the radio. If you have already done the initial calibration sequence, you might need to use a hotwire to increase the neutral width setting to widen the window that the RSX considers as neutral. This feature is there to prevent the esc from applying any power unintentionally when you first turn it on.

Widen your neutral width setting to 10. Re test.
