Good day!
I am using an Orion Vortex 17.5 brusless in my T1FK04 with a GTB speedo. I am new to brushless an am wondering if and when do you play with the manual timing setting on the motor an do you change the gearing as well as the timing?
Thanks Neil.
It depends.
More timing = More power = More RPM = Less Torque (But not much less) = More Heat (With same gearing!)
So, you want to have more power, then you need to increase your timing, and then regear the car so you dont melt the motor down. The less torque can sometimes help. I have increased the timing on my 10.5 to reduce the wheel spin coming out of the corners in my pan car. Its helped alot. I then put a smaller pinion on to keep the temps in check .
The motor will make more output power, but since its less effiecient with a higher timing, it will also drain your battery more, so make sure you have the extra capacity.

here's what Novak suggest for a FDR http://www.teamnovak.com/tech_info/brushless/br_gearing.html (http://www.teamnovak.com/tech_info/brushless/br_gearing.html)

Having the same problem but I am looking at the throtle profiles in the gtb first as my motor temp is down at least make sure you change the timing in small increments

I don't think 3.5:1 FDR is too realistic. That's in the neighborhood of 56 pinion/96 spur for a T1. 64 pitch.
The race I ran last year without a timing advance speedo I was at 4-4.5:1 if I recall correctly, which worked OK. I originally had it set up for 3.5 as per the chart, but Phil set me straight. I don't think the Novak chart has been updated for quite a while.
