Remember timing is another tuning option or tool. It's not mandatory that it be adjusted that's why it can only be done via the Tekin Hotwire. Quote from Fandy Pike "Timing affects the KV so higher timing is more rev's, less timing is more torque. On the 2050 I run timing low since for me it's already a lot of motor: I run it at 10. On the 1900 I'm up around 25-35 depending on traction,etc.

Another way to look at it is, if your motor is the 1900 and your timing is set to 10. Your running 4s on a small to medium track but your topping out early on the straights. Instead of gearing up 1 tooth on the pinion, you would try bumping up your timing in small increments to see if you could get a little more top end for the straight.

The side effect of higher timing is temps, so be sure to watch them. Different KV motors running on different voltages (4s/5s/6s) have a sweet spot when it comes to timing. Since your running 4S you are able to use timing as a better tool than myself who runs 6S. On 6S "0" timing has a very slight difference to "10". The one thing I noticed was motor temps were 10+ degrees higher with timing at "10".

Sorry for the long post, this was something I really wanted to figure out when I got the RX8 as I was having issues of burning up expensive motors and I wanted a setup that would run a cool motor.

BTW, post up some pics of your Castor fleet. I am not a direct drive fan, but I have always liked the Caster buggy and truggy.
