This is my New version of the Pulling Sled. it has now a heavy modified version of the 8448 set gearbox. to make it smaller i had to remove 2 gears. i also "inverted" the gearbox so it fixed in the back of the Sled. the gearbox makes the carriege move faster or slower to the front of the Sled. also i use now a normal rope instead of the elastic rope on the first version. this makes the sled stronger so you can add more weight on it. so it now has more functions that make it more realistic and is only slightly longer then the old version. if you have any questions or comments, mail me at gt4rulez8@hotmail.com or add me on msn.
