To supply enough heat to melt those thick tracks would mean you'd have already reflowed all the solder holding the fets down and the speedy would not work at all instead of just having it go into motor damaging, gear stripping reverse, instead of turbo.

Turbo kicks in with a massive timing advance that is taking the final timing way over the 60 degrees mark and causing the motor to spin backwards ,as in 60 degrees is the half way mark of 120 degrees which is the number of degrees between phases of a BL motor. (360 / 3 = 120)
does it do it on minimal turbo settings ie.turbo 1, & timeshift 1?
is your x12 on zero/minimal mechanical timing?

I am running 11.5 motor. Want to know RBS or RB50 which provide faster turbo?

What is the new 1.2 firmware improved?

I can't see how that could happen, the power wires are on the main supply tracks which are quite thick and the motor wires are usually connected to the thick commoned fet tracks, the fets themseves disipate heat from those connections directly via the fets own ceramic case straight to the heatsink.

Note that BL motors are also very sensitive to dry solder joints, a solder joint should be shiny after its dried, with all the individual wires fully sealed.
You also have to be very careful of how long the heat is applied, solder should be applied to both items seperately, and then the final solder joint is to just meld together the 2 prepared pieces. You should NEVER apply solder to an item that is being heated for a long period of time.

I think the LRP literature actually says don't use profile 7 or 8, I realise the ramp on the rb-s is of the same agressive nature as the SPX which is why I ran it with item 5 (Drive profile) set to 3 of 9 and the turbo set to 1x.

I had it on -5 and mark had it on 0, did the same thing, except if you turn off turbo completely.

Same here. If TW can't provide me with an RB-S that works NOW, then I want a refund NOW. Having to wait ANY length of time is just unacceptable. I wouldn't mind seeing the speedy recalled either, until they DO get it working and tested with at least the current top 5 motor brands of each class. Either that or specify in their literature that their ESC only works with motors x,y,z.

Hi,
RBS firmware 1.0b is now available for download. It can solve the "reverse" problem. It goes reverse since the turbo kick in too early on slow motor like 17.5T & 21.5T.
Customer can contact us if they still suffer this problem.

I bought the other RB-S from Windsor and I have exactly the same problem, both rbs's are already set up as forward only, If you cruise around at half throttle it will go forward but as soon as you mash down on the throttle it sends the motor from forward to reverse with no pause or delay inbetween.
Reverse isn't a gentle or half throttle reverse, no, its full on reverse at top speed, it even brakes traction and does tyre spins while its in reverse.
I'm running the x12 on an 09 xray like Mark but of the 21.5 flavour, the wires are original and so far I now have multiple stripped / damaged gears and other bits in the drivetrain, the x12 is also buggered / cogging like crazy now but I supose instantly going from half throttle forward to full throttle reverse would tend to do that.
Very interesting to note is that if you completely turn off the Turbo function, as well as having a slow car, the RB-S behaves normally and will NOT go into full reverse.
Speedy, motor and stripped spur have now been swapped out for a brand new x12, a near new Orca and a new spur, everything runs great now.
To me it appears as though instead of hitting turbo the RB-S is going into reverse, my guess is either;
Turbo kicks in with a massive timing advance that is taking the final timing way over the 60 degrees mark and causing the motor to spin backwards ,as in 60 degrees is the half way mark of 120 degrees which is the number of degrees between phases of a BL motor. (360 / 3 = 120)
There is a firmware error where the reverse function have been missmapped or overwritten into the turbo function memory address range. (sorry I'm showing my decades worth of expirience in microcontrollers)
