Im lookin to build my own dragster. I have built a crawler and a mud skimmer from scratch and now i need a dragster to add to the collection. I seen one the other day and I dont know how he done it but it was electric and he could hold the motor wide open with out it even moving. Then its like the motor moved into place and it took of. Thats my question, does anyone know how he done it and what I need????
