endurance race ?' s
 

Entering a one hour endurance sct race. I have a 2WD slash. Anyway what would use less power? Stock titan, 13.5, or a 10.5. I figured more powerful and take it easy on throttle and my battery would last longer. What do you guys think?

As best I can figure the stock titan would be in the 3100-3500kv range

A 10.5 would be in the 4200kv range
A 13.5 would be in the 3600kv range

The brushless system will be more efficient than the brushed motor (and more durable).

For an endurance race speed isn't everything. Keeping the car on the track and in one piece is the main focus. A 13.5 will allow you more runtime between pack swaps and have less stress on the whole car.

Thanks, that's what I kinda figured. Now what if we add a second battery for longer run time? Do you think the 13.5 will still be ok?

I agree 13.5 or even 17.5 or 21. I wouldn't try the two batteries because the advantage in extra run time would not be better that the extra drag the added weight would add to your chassis.

Remeber you're not gonna win in the first half of your laps, consistant safe driving wins these races, that and lots of beer!

Lol I'll have to bring some of that. Thanks guys. Now I need a quick battery change trick
