Yeah i just finished my TTD Model, well not completley, its about 7 inches tall & made off 100% ToothPicks its taken me 4 days, since i started saturday morning, all i have done is the main tower, i still need to make a little christmas tree, & a little station, it should be around another week, since i have school for half the day, but i cant wait to post pictures, & im adding and engine room to my Knex TTD, Okay heres how it goes, i made a Light up Christmas Tree for my Knex TTD, then i just ran the rest of the lights through a paper towel roll under the launch track, then into a little box i am going to make look like the engine room, then all the lights will be lit up & I glued the Sign that reads the speed off the train to the engine room, & then with an exacto knife i cut out a 121 wheres it says "Your Speed, so you can see 121 lit up in the dark its sooooo awsome, & i need to get another screaming serpent to Finish My Millennium Force, but i cant find them anywhere.... It really sucks, OHHH yeah & also My Knex TTD works on rubberbands, & launches a screamin serpent train, it almost dosent make it over itss sooo awsome, its kinda a pain, when i have to change the rubber bands, because they snap after about 20 or 30 launches, or else the band frays & goes into the plactice faces of the riders, & last but not least i also on every other 5 inches i covered the red track with masking tape so the track is white red, white red, ect but ill get PIC ASAP ill try to do it tomorrow, have them up in 24 hours thanks.....tell me what you think...
