Hi Everyone I am in the process of putting together a 1/64 Dragstrip that I bought from MaxTrax racing .Can anyone tell me how to wire the dynamic brake section after the finish line there is a positive and negative wire on each lane .Thanks Dennis Laff
Good morning Dennis, i don't have max traxx but i would believe you make sure thier is no power to that section of track and simply wire positive and negative in each lane im sure some one with max trax will have information as well good luck and welcome gnome
make sure that there is a good gap between the powered racing sections and the beginning of the shut down rails. you can solder a set of wires to some of the "joiners" and slip them in at the end of the shut down. you then provide reverse polarity voltage or dead shunt. I like to use a 9 volt battery for each lane, but some folks prefer more voltage. don't expect miracles, this "dynamic braking" will slow the cars more than just a free roll, but it won't appear dramatic. option !!!! instead of actual track in the shut down, use steel bar strips about 1" wide, 1/8" thick as the shut down. screw these to a board and leave space between them for the guide pin. these can be shunted or reverse polarity powered as well. the additional steel will help slow down any car with traction magnets.
any case of using a shunt or reverse polarity on the shutdown rails .... you MUST insure that there will NOT be a connection that will short the power supply when the car pick up shoes transition from the powered rails of the racing sections to the shut down rails.
Here are the 3' steel stop strips at the end of my track. They are 4 - 3' x 1" wide x 1/8" steel strips that I purchased at Lowes. These will stop cars with good traction and motor magnets. I have run over 60 mph on my track and stopped the cars with 3' of dynamic braking, 3' of steel strips and a catch box.
