Hi guys, I have owned the ST-15 for a month now. Have the following mods. Bearings, Proline Dirt Hawgs on all 4 corners, Upgraded the switch to one with the charge connector, and had to get the battery holder with the Futaba J connector, Tower charger for TX and RX, 700ma NiCads all around, and Tuned pipe. GT10 parts are on order. I broke it in with Duratrax Red Alert 10%, Head temps were running around 250, seemed to be running around 30mph. Started using Blue Thunder 10% and it seemed to get another 5mph or so. Removed the exhaust deflector and got faster yet, seems to be going around 40 now. Head temps still around 250. Installed the tuned pipe, and temps shot up to about 330, and can't run through a full tank of fuel. Lengthened the pipe as far as I could, (hits tire now when I turn left) and the temps dropped down to around 310. Still vapor locking. Went through Harry Higgly's "All about engines" book and seems that overheating is caused by too short a pipe, and 2 ways to lengthen it are physically,(no room) or by running higher nirtro content. My question is, What nitro level are you guys running with the Tower pipe, and what temps are you getting?
