Ok you go racing on larger tracks. Than it's a thing that makes it a bit faster.

X12 17.5 with RS V203
Medium size asphalt track, high bite
Touring car (Cyclone TC)
Rubber tire

I will be running this combo tonight for the first time, any insight into a starting point is appreciated.

You guys wanting the x12 17.5 might try to send a pm to bigdogracing.

Local guy where I race from was using the LRP with the Tekin the other weekend. Give him a try.

Nope. The only time you have to recalibrate is if you change the firmware (going from version 200 to 203).

I have a problem with the tekin rs pro

The problem is this:
use the v203 tekin with software and with these values:
4 trottle profile
Timing boast 35
turbo boast 10
Dealy 0.2 turbo
3.0 turbo ramp
Start RMP 4678
end rpm 12500th
Final Report 6.5

The problem is that the regulator is very strong, but after 3 minutes significantly diminish the performance as if any further attacks on the turbo, I tried various things but I do not know what the problem is, my friend uses tekin like me and with the same settings and has no problems, and how I use ezpower lipo 50c

give me a hand to understand the problem, thank you.

The X12 has a high motor timing so start with 30 to 35 Boost.
Use max about 40 Boost.
watch the motor temp.
Turbo delay ad least 0,4 sec. 0,6 is better.
Turbo around the 5.

Gearing for the infield.
Start RPM 5000
End RPM 10000

Castle creations swears by sensorless operation and i have heard that at higher currents and rpm's that the sensor readings can drift or become erratic. is sensorless still too imprecise to add the cool timing tricks to dual mode?

mikky32

Witch motor are you using?
X12, Novak, Tekin, Duo 2?
What is the motor timing and how many turns?
13,5T?

Sensorless gives the best performance and can make the motor spin faster for a given KV rating. The problem with sensorless is that starting is not as precise or as torquey as sensored. The other thing that you will notice is that the breaks are not nearly as strong as they are with the sensor only mode. Both the RS and the Max pro can run in hybrid mode with starts the motor with the sensors and then switches to sensorless operation. This is the more effecient way to run the motor but lacks the grunt of the sensored only operation. For mode motors lower than 10.5, running in hybrid mode makes sense and possible (with the exception of breaking) is better than say running a GTB witch is sensored only, with the same wind motor.

I am currently running only sensorless motors in my mod 4WD buggy and having no issues at all keeping up or beating the people running sensored motors. And yes you can even give it a timing boost, but the amount is not the same as when using the sensors to apply timing.

When I get some time I will be making a comparison of running in hybrid mode in stock vs running in sensored mode with timing and turbo.

I was having a similar issue and it turned out to be a couple of cold solder joints. As the controller got hotter the efficiency of the connection was degraded enough for the car to slow down on the track. I was racking my head all day and at the end when I was putting everything away I decided to pull on all the joints (the ones on the speed control) and found that two I could bend and twist off. The joints where cold solder joints and not making good electrical contact. I usually use and Ohm meter to check the joints before race day, but I was traveling a long distance to race and was in a hurry. The joints cost me about 1 sec a lap under the pace and no matter how I geared or messed with the controller it would not make up the difference. So I would make sure the solder joints on the motor and speed control are good.

hope this helps.

No welds are fine

Change the following.
Set the motor timing on 5
Timing Boost on 50
Turbo on 5
Turbo delay 0,4
Turbo ramp 2
Keep those RPM settings and gear a bit lighter.

I think that the timing is to high and to much ad once with the low Turbo delay.
What is the motor temp?

Looks like I am now that I've been called out on one of the most active threads on RC Tech

May 14-16 B...I don't know about the personal jet, better bring the hovercraft!
