Just ran my RS/Redline 17.5 combo today and so far I'm I'm one happy customer. Plenty of rip and speed, and never got over 145F all day. Last time out I ran an Xcelorin speedo with a Trinity 17.5, and making similar power had that motor coming off the track between 170 and 175F.
Been using Tekin products since 1988, and the only thiing Tekin hasn't managed to do yet is disappoint me.
Thanks
