3.25 is really low FDR i am surprised you havent blown it, i blew up the same motor running a higher FDR.
An FDR of between 3.6 and 3.8 is go with one of the motors previously mentioned on an open asphalt track and will give you great top speed.
As long as you are running a lipo of over 40 or 50c it should be fine.
Get a revtech, orion or LRP motor and have fun going fast instead of struggling at the back of the pack.
Check out the videos of my track in the links in my signature to compare your track to mine, but we run a reasonably long front and back straight, maybe 30 or 40 meters
Thank you for the advice. I have a fan on it and measured 52 degrees on the motor in 10 degrees ambient (celcius)
Thing is I actually won with the car. But my best lap was 0.7 secs slower than the fastest car (19.8s vs 19.1s) but my average lap was 20.1s so it seems consistency wins the race! I thought I did ok for my 3rd meet ever
I just don't want to be outdragged and put at the back of the pack in qualifying. Also it's very frustrating to overtake someone after hard work in the corners just to get blown away on the straights.
So an FDR of 3.6 with mechanical timing would give a better top speed than 3.25 with none?
Thanks for the advice so far guys. It's very helpful. If someone could recommend a reasonably priced light lipo that would be great
