I have finally hit the track yesterday, the car was really turning well and had good traction. however I had a big issue with motor slipping under braking.. I used blue locktite inside the screw but it didn't help..it happened like 5-6 times.finally I gave up. I checked the building but there is no wrong thing.
where shall I exactly apply blue locktite ? shall I apply it also around the metal ring that the screw goes into? I am using Tekin 2050kv fyi.

many thanks in advance.
