1º - The most important is to manufacture two alignment bracket (a pair for each of the most important, and popular Starterbox, such as Team Magic, Serpent PowerStart 90 starterbox ..) so we can start the XB-8 with the same perfection as we start a serpent (on-road car) using the starterbox. It’s easy.. just have to build a front plate, with two small towers where you fix the bumper sides (in way the front of the car does not move laterally). - In the back, is enough a small plate to fix the top end of the chassis.. It’s easy, cheap, and well received;
2º One Piece engine mount
Congratulations, the car is very good
