Item No: 1A301 - RC Car Nitro Engine Combo Set

Here is Ty Tessmann's OS powered HB D815 V2 at 2016 IFMAR Las Vegas (courtesy of NeoBuggy). The cooling head is nicely flushed almost under the body.
According to Ty Tessmann, prior to IFMAR event he has been testing this new engine for a few months and says that there is no difference in engine temperature but the handling difference is quite large. The car is more predictable in the high speed corners as it doesn’t dive upon turn in.
