Anyways, there is a guy by the handle of jzemaxx who put a neu 1521 1.5d in his 1:8 scale XTM MMT, though he used a custom ordered 1524 1700kv motor for his record attempt and made it to 80.4mph, though he was running a somewhat higher voltage @ 10s (several threads, this and this one are a good read).. I think the smaller neu you are using will produce more power on the same voltage compared to the larger neu (based on my fuzzy logic/mathes), but if you were to step up to a higher voltage MGM, use the larger and lower kv neu, it would easily produce much more power to get you to that ~100mph goal. My only concerns then would be tyres exploding, tranny and diffs exploding, and general aero dynamics- very long upside down skids as seen in that video.
However, you can belt the tyres or use MT foams, beef up the diffs with rc-monster hybrids or LST2 modified diffs to fit the erevo bulks, and a drag-bar or very big wheelie bar should help keep the nose down, along with maybe a front wing. |
Yup that was me......80.4mph on camera. Did end up going 85mph on the GPS off camera several weeks later, but got tired of replacing tires so I quit. The XTM dwarfs a E-revo which is much lighter so speeds should be easier to attain with it. I would think with my old setup on a E-revo it would have gone close to 90mph. I was running 12S.
. I had another setup that was ready for testing that would have pushed the XTM over 90 with a 1527 and 20S. 20lbs with 12S, means with 20S that truck would have been close to 25lbs
Tires would never have held....... Now I'm racing and the XTM is parked and hasn't been off of shelf for quite sometime.
