I know there are better engines out there, but I can get one of these for a $100 even? Between these two engine's which one would be better for track conditions? I go to track and just practice a lot. Which one is more reliable ,powerful, torgue rpm, etc, etc? 1. Ofna force . 28 2. Hpi 4.

6. After speaking to others on the web, I found the answer. Well really, they are the same engine ( as in displacement) but for relibility the Hpi 4. 6 is reliable and fast ( its in the hpi savage x) but the ofna engine is also fast so really its a toss up. They are both good engines. Get the cheaper one of the two. (preferably hpi 4. 6)
