gps proven speeds stock, mmm, & 6s lipo -all stock gearing
I have looked on here thru the search tab for gps proven speeds for the summit...i can't find them entering key words. I have seen speed charts of what things should do, but I am going to gps test several gear mods. the pinion gears I will us are [B]14t(stock), 18t, and 24t.[/B] The spur gears I will test are [B]68t(stock) 65t, 62t, and 54t.[/B] I am looking for a good set up with my MMM motor to get good high speed crawling in low gear (I crawl over long rolling grass and big rocks), and get 40-45 mph in high gear.
I test with a garmin 765t mounted on top as pictured[IMG]http://i145.photobucket.com/albums/r212/cnoevo8/IMG00006-20100118-1942.jpg[/IMG]
here is what I have found so far.
[B]low gear: high gear:[/B]
[B][COLOR="red"]8 mph stock 16.8v / 21 mph stock 16.8v[/COLOR]
[COLOR="Navy"]12.1 mph mamba monster (14t/68t) 16.8v / 27.5 mph MMM (14t/68t)[/COLOR]
[COLOR="DarkGreen"]14.8 mph MMM (14/68) (2)3s 5000 mah lipos / 38 flat mph MMM (14/68)(2)3s[/COLOR][/B]
now thats with stock gearing, crawls great tons of fun. As soon as I receive the rest of the parts I will add to the post. I could not believe the difference the dual 3s lipos made, at 1st I thought I had a bad motor when the speed with 16.8v only went up marginally.:lol:...more to come if warranted.
next I will test the 18t/68t, then the 24/68, then move to a different spur with the 14t pinion and then the 18t pinion and so on. let me know if I should continue or am I just waisting my time.
new lowered stance top speed run.
I switched my tires and wheels to ERBE and gave it a shot at the top speed for an [B]18t pinion / 68t spur [/B]with[B] H.D. blue fronts and H.D. purple [/B]springs in the rear. just by lowering the stance and switching the tires out I got [B]15.5 in low and 31.3 in high gear with my MMM[/B] will test 6s lipos next!
here is a pic of how it looks now
50 mph with 6s lipos on balloon tires
Here is the top speed just achieved with [B]18t pinion, 68t stock spur[/B], 6s 30c lipos, lowered, on ERBE wheels & tires (that ballooned up like crazy):fear:
[B]YEP 49.8 MPH[/B]. I tried switching to [B]harder tires [/B]and was only able to achieve [B]48.5 mph[/B]. tested in a new smooth parking lot not opened to the public yet!
