I had the SH .28 in my XTM XLB ( it comes in the XLB) and it really ran good. And that's a 1/7th scale. If you're buying it brand new you might want to consider something like the XTM .457 just for the fact that it does have a little more power than the SH .28 I'm not sure how much you're paying for the SH but I've seen the XTM for about $150 and the XTM is just about the same motor as the LRP .28 which I absolutely love. But if it's the SH you really want you won't be disappointed.
