What about your motor timing guys ? I will probably put mine at 6 or 7 to maximize efficiency...
But it's out of stock!!!!!!!! :( :( :( :( :( :( :( Hope Mike will restock soon.
In fact i am still hesitating between this one and the 1717... but I am not sure if the RCM motor mount can handle a motor this big :(
Magman, do you have some space between chassis and your motor with RCM motor mount, or it is already too tigh with the 1520 ? The 1717 is larger..

1. I did put small washers between center diff mounts and chassis to raise everything up a bit for more clearance

2. I have the motor timing to 0

3. IMO the 1717 is too big for a truggy, heck the 1520 is a bit on the large size, but, I wanted a motor that I would not have to worry about. I was running a 1515 ccneu before and that was just fine as well
