7.1 FDR motor timing 5.
You can also try motor timing of 10 but I think 5 is enough.
Watch the temps but the Speedpassion can handle the timing.
Thats quite a lot of changes compared to my existing one. I can see the logic behind it i.e using the throttle profile no 5 to calm it a bit. I never thought about doing it that way.

I'll give that a try next race meeting, thanks.

What's the idea behind adding the 5-10 degrees of actual motor timing though. i was under the impression 0 was the way to go for punch or is there negative timing in actual fact on the motor when set at 0 ?

The 5 to 10 motor timing is for the lighter gearing for the first meters.
But the Turbo will kick in soon and will take over.
Start with 5 on the motor because I think it's enough. 10 could be to much because of the 15 Turbo.
You can also set the motor to 10 and Turbo to 10.
Play with the Turbo ramp.
As the ramp of 3 is to much set it to 2.
This way you play with throttle without using the throttle.
When you don't use full throttle, you car is reacting a bit slower. It will not take off as a rocked. This way you can drive easier in the infield.

I used Turbo ramp of 3 with 10 on the Turbo with a 10,5 and that was way to much for me. 2 field better. Look what works best for you.

What is the lowest turn mod motor I could run reliably (not worry about thermalling) with the non-pro RS?

Even though it says down to 5.5, I somehow doubt it....

Does anyone run a mod motor with the std RS? Care to share experiences?

I ran a 6.5 in mine with no issues. I wasn't racing. I was just playing around on the track. I did put about 3 packs through it.

The RS is rated with a 5.5 in a 2wd application.

There are many factors involved in thermalling. Esc placement, air flow, setup, track size, driving style,etc.

In TC if you're going to run mod get the RS Pro.

Randy, thanks for the clarification on the RS turn rating.

I blew it by not buying a Pro at the outset. But, I wanted to save a few bucks.

(how many times am I going to have to learn this lesson...)

Default Sorry to Repost This Question

Sorry to repost this question but I did not really get much for response, please do not take the rpm ranges to heart, just looking more for disussion on pros and cons of different methos of appling timing advance.

I am debating the following two methods of Appling timing advance in a 1s 1/12th scale or WGT class.

Motor 13.5

Option 1 - Apply timing throughout the entire rpm range (800 - 8000) I understand this should give me a smooth feel and apply the timing over a longer period of time.

Option 2 - Gear motor with physical timing to pull hard in infield and set timing to be applied after motor runs out of power on its own say (5000 - 8000) understanding that it is going to apply the timing much quicker.

This would be for a small to medium carpet track with some slower sections. I fully understand that you would use different gearings for these two different options as well.

Just looking for thoughts on these two different methods of applying timing advance.


Thanks

Look at the bright side, the RS is still in high demand so you can sell it for good money if you can't use it anymore.

Default Duo 2 timing

Does anyone know what the timing is on a duo 2 13.5 when at the 0 middle notch and by how much it increases per notch ?
Thanks

The Zero mark in the center has 8 degrees built into it and each notch after that is 8 degrees as well.

I have found that 0 endbell timing is best for 1S.
With Yangs 13.5 setup listed on the Tekin site you will have a lot of punch and top end.

Option 1 is your best bet. Option two would be too narrow of a timing curve and will not get you the torque down low where you want it. Their top speed would be similiar but the motor will run hotter in option 2.

You can take Option 1 and narrow it up a bit using a start rpm of around 2,000 and end rpm of say 7500 or so. This will be an "inbetween" the two.
