Ridge
This inline mod has the Esc placed in the rear of chassis with the inside middle of the water fall trimmed. You put the Esc under the water fall, receiver goes on rear side next to battery like we use to do with b4.
We're also trimming the side rails of chassis brace thinner so the chassis can flex more in the area in front of the water fall to the servo.
Trim the plastic in between the battery thumb screws so battery fits inside.
Doing the mod today.
