With Turbo 2x , Reduce your time shift. nor reduce your 13.5 Motor Timing.

Oh.. and if you willing to get for more punch
Try "Twin Turbo", Instead Turbo1x or Turbo 2x,
with "Twin Turbo" you will get Both a lot more Punchy.

How was the mechanical Timing? I found the motor RPM come high when Timing is at maximum.

Twin Turbo????

AdminD

Never use Mechanical Timing (Motor) when Using Turbo on.
meaning Motor Timing is at max Torque.

Rising Motor Timing will Have more Draw with less Torque,

Turbo required certain RPM to reach, if it's too soon your Motor Get's Hot.

When I use my RB-S with a 10.5 my FDR is around 5.5. I think 6.8 is way too high for 13.5. If you are way under-geared you will have no punch or top end.

In 10.5 I run timeshift 4 or 5 and twin turbo(2 x turbo).

Always check your motor temps after a minute when changing gearing so you don't melt it.

The speedo was fast but not as fast as the Tekin and now the SXX ss.
I had the same experience with him. He was struggling with the power.


I agree that they will find something.

Thanks guys,

I agree that the gearing was way too high, but I was trying to reduce temps.

I think you may have hit the nail on the head with mechanical motor timing though, Im running fully advanced. That is probably why it is too hot all the time.

Next time out I will go back to more sensible gearing (5.2) and try with no motor advance.

What do you guys think about time shift settings? My general approach at first was low time shift, gear for punch and rely on turbo for top end.

I didnt really notice any benefit from turning time shift up, I gather it should give more torque at low RPMs at the cost of heat, is that right?

Thanks again

No, Time shift of 7 will take away a bit off punch. That why run a bit less. Too low(1 or 2) and you will lack some mid range and the turbo will kick in not so smoothly.

Redwood

Thanks Pablo.

Ok I will try in the mid range.

My last question would be, what exactly is the Time Shift doing?

I thought it would be how the timing ramps with RPM.

Also, if time shift 7 is bad all round, why add it to the RB-S settings.

Thanks

So what you advise? No timing and Low or high gear?

Thanks in advance.

My RB-50 just died on the weekend. The motor got burnt after 3 minutes. I put in a new motor to check if the speedo is still OK, turned the speedo on and it gave a continuous beep sound so I turned it off. Then I turned it on again, no beeping this time but a quiet swoosh sound then some burnt smell... dead.
I was running 4.5FDR time shift 6 and motor timing in the default middle position, turbo 1 on a wide fast track, RB-S program.
My friend overheated a 10.5 on the same day running the rb-50 with the RB-S firmware but his speedo survived the incident with no problem.
I have burned one or two motors before but those did not kill my LRP speedo...

I see a 10.5 for your friend but what did you fry? Pretty sure it was stated here that you shouldn't run the RBS firmware on the lower turn motors.

It was a 13.5 SP V3

You have to be careful now days as short motor wires will always transfer a lot of heat to the speedy from motor and if you burnt out the motor then unplugged battery and you have short motor wires you may have transferred excessive heat to the circuit board!! I have realised this due to some people changing speedy wires and then poof up in smoke because they have overheated the circuit board!!

You should not have burned out your speedy with a 13.5 motor even on twin turbo. Its more likely that when the motor went up it shorted out internally and caused permament damage to the ESC's FETs. I have seen plenty of brushless ESC failures over the years right after a motor was tortured to death. This is the most likely senario but if you think the unit was fault then look into returning it for repairs and get a definete answer.
