Problem: |
Solution: |
Brakes dragging during acceleration, melting teeth. |
Adjust your brake linkage so that when you apply throttle your brakes are not on. |
Your linkage for the brake and throttle should be set so that when the throttle is applied, the brake will disengage immediately, and when the brake is applied, the throttle will disengage. When the linkage is set improperly, the brake may remain engaged during throttle, overheating the brake. The spur gear is not mounted very far from the brake, so when the brake heats up, the heat can travel to the spur gear and melt the teeth.
To check if improper brake linkage is the problem, do the following.
1. With the engine off, apply the throttle and see if the spur gear spins freely. If the
spur gear does not free up immediately when applying the throttle, then you need to adjust
the linkage.
If you need to adjust the linkage, do the following.
Adjusting the throttle linkage:
1. Cut the wire ties and remove your air filter. Turn on the transmitter then the kit's
electrics (don't start the engine). When at idle, adjust the collar near the adapter so
there is up to 1/16" of space between the collar and pivot.
2. Apply full throttle. Your carburetor should be fully open. If it is not, then adjust the collar nearest the adapter. (You may also adjust your throttle trim. See your radio manual.)
3. Now apply the brake. Your carb should be at idle position. The spring should not be completely compressed.
Adjusting the brake linkage:
4. With no pressure on the throttle trigger (at idle), adjust the brake nut and spring so
that the brake is applied slightly. You can test this by turning the spur gear. The spur
gear will have some resistance to being turned. Also, keep about 1/16" gap between
the collar and disc brake cam at idle.
5. Now pull the throttle. The brake should disengage immediately. You do not want the brakes to be engaged while the carb is open or you'll damage the engine.
6. Now apply the brake fully. Your brake should fully engage. The spur gear will be hard to move. If it is not, then adjust the collar.
