LRP SXX StockSpec ESC
#211
What is wrong with the moon, aim high I say
Have a KO BMC for Mod, but the question is more aimed at 12th scale.
With SXX ss duel BEC system not having to run a battery or the like to get 6v to the rx. I don't want to use a second ESC to run a motor as low as 4.5 or 4 that removes the advantage of this ESC.

ok so i have this cogging effect when revved on the bench is this ok or do i send it back. Not got a chance to put it down on a track untill the weekend to check it. let me know guys cheers
#213
Just give them a try on the track first... LRP didnt design the speedo to be rev on the bench... they designed it to be raced on the track where there is load involve... Dont be so quick to send it back to LRP...

Tried a SP 13.5 V3 motor and the same happened. Sorry to say, but reconnected by existing ESC and the motor ripped !
I've heard of the issues with the 1st batch (which seems I may have ) but I've also heard that this may be the normal charactoristics of the StockSpec when running the motor with no load.
If anyone has had the same experience or can shine any light on what the exact production issue is on the first batch released, then it will help me understand if my ESC is faulty or just how it is ?
Cheers,
Jason
Mine did same thing - returned it to shop after 2 qualifiers. I was later told that there was issue with installing firmware (can't say it's right reason or not).

To explain the differences and the slight stutter when testing on the bench...
First of all it's not recommended with any brushless speedo and/or motor to let it rev that high at no load on the bench. I know this is popular and common but it clearly is not good for your equipment.
Luckily we still don't race on bench either but on track...
Anyhow, some guys discovered small stuttering not only on bench but also on track, while other guys were/are completely satisfied. As we prefer to make all our customers happy of course we worked on a further software update after Snowbirds race, which is ready since last week.
So all the speedos shipped since end of last week are the most recent software, which we call "MkII" which solves the stuttering completely. So if you didn't receive your speedo yet, it's very likely you'll get "MkII" already as not many with 1st batch software had been shipped/sold anyway.
Now you'll certainly ask yourself, how do I know which software version I got? This is quite easy, please proceed as following:
- with everything installed (motor must be connected properly!) and set-up to your radio.
- turn on speed-control and listen to the initial beeping.
- with "MkII" software: you hear two short beeps
- with 1st batch software: you hear no beeps at all.
If you got 1st batch software and would like to get it updated, please speak either to your countries LRP distributor (in USA it's Associated) or you can also contact me directly at LRP in Germany. We're able to do a firmware update but the speed-control needs to be sent in for the update so far as no update on your end is possible at this stage.
I hope this clarifies things for you guys.
Clearly the MkII solves everything but I would like to repeat that many guys also had no issues whatsoever with 1st batch software.

Reto,
Thanks for clarifying this in public. This is how all companies should communicate with its customers when there are issues.

Which is better? LRP SXX Stock Spec vs LRP SXX TC Spec? What's the main difference that creates an edge of one ESC over the other?
These ESC are stated to be sensored. Can they run sensorless?

burito, I recently ordered one of these. Not sure if it was the first batch or not. It was from Superior which was the onsite hobby shop for Snowbirds. Does the speed control need to be updated regardless if it doesn't have the latest firmware or just if you are getting the stuttering? My concern is that since I don't know what causes the error (say its the receiver you use) it might work for me initially and then down the road begin to not work? Or is it just some kind of corruption that either exists or doesn't?
Thanks.
Thanks.

Thanks. Now though, the question is what can we expect in terms of added performance. I find it frustrating that I have found no mention of this new ESC being able to perform on par with its competitors. Have there been no successful tests? I have been loyal to LRP for a very long time and want to continue this, but I hate to be let down again as I was with my two SPX's. Come someone give us some real world info on the performance gains if any.

For mod sedan 2s lipo, is it best to run the SXX TC Spec or will the SXX Stock Spec be fine?
