agree,,agree,, and agree but, idid all the above ,yet had to cool down between runs,, once i got the cooling mod and the PTE theromstat my temp stays below the 1/2 way mark,, as for the track i made a 4 round ,,round robin first run 8:01pm 12.29,, 2 run 8:12 pm 12.26,, 3 run 8:19 12. 31 4 run 8:26 pm 12.29 again and i could have kept going if needed,,, Rmaderman has been doing this for months. this to me makes the cooling mod well worth the money. jim
