If you would, I will try your break setup for you. I will post in private and give you measured dimensions from start to finish.
Will also set criteria to maybe aid in the product's development. I think the brakes are a little lacking on the Losi as well. In long mains I can feel a little fade.
I race two times a week and usually get in 1 to 2 full days of practice on top of that.
I'm not the fastest guy by any means. However, when it comes to products and engineering, I'm there.
Let me know if I can help.
