I just recently got my Rustler running on 4S lipo and a 36-60-2000 medusa and haven't ran for more than 10min in a row without a trans failure. First it was the planetaries, then the plastic diff, now the VXL-steel ringed diff ate the aluminum idler gear. I'm going to buy a FLM trans case to see if that helps at all.

Are you running a steel idler or aluminum? What Zippy lipos are those that you have in the pic above?

Thanks Raze, Phildogg is right it's a VXL trans, with original gearing

The lipos are 6S2P Zippy Flightmax 5000mah 25C...on loan from a trusting friend. I'll be returning to 4S for some runs next week

I thought it would be interesting to replace some parts when they failed rather than do everything...I'm impressed with nearly everything. If it wasn't run over by a 1:1 car earlier this year, I suspect I'd still be using the stock plastic trans

When wind resistance exceeds the traction between the tires and the road, that is your maximum speed no matter what (likely less than 100 mph for rustler)

I know it is fun to try to make something go fast that shouldn't but be warned that it will cost A LOT of money and time, and if you do not do a few calculations, trial and error will be endless. The other people who think they are shooting for 100 mph in a rusty will very likely not actually get there, so there really isnt anything to worry about in terms of competition. Just shoot for the highest possible speed you can get and be satified with that. Once you realize that you may have to shorten the A-arms so the wheels fit underneath a nice compact body, and that the front end has to be virtually weightless, there may be nothing left that resembles the original vehicle.

If I knew this a bit earlier...

I'm also doing speedruns, it's with a Vendetta 1:18, and yes, every time I drive there get's something loose, stuck, there overheats something etc. And it is really disappointing every time I have to cycle back to home for just 5 minutes of fun. I'm trying to get 62MPH with my Vendetta with a Quark 80B ESC and a Mamba 8000kv motor on 3S. I know what problems I've got, but I haven't got enough money at the time because I'm only 15 and I'm building a brushless LST 1:8 and that thing is VERY expensive

Anyway, to go ontopic, the car looks awesome IMO! When will you make a movie from it? I also have a Rustler VXL, I love the car, but I can't even imagine how it would be driving that car at 100MPH!

Good luck with your speedruns, and be carefull

Thanks Byte, I have some below average video already on youtube. The last run was using a friends camera & when I have that footage I'll be posting...it should sound good!

Good luck with yours. Have a look at www.rc-isc.com it might interest you

Here's the video of the lastest effort

80.2mph

It's incredible what speeds some people get. The fastest Vendetta I know is the one from Nic Case (82MPH) and there are some other vendetta owners who get speeds of 70+ MPH.
One question about that ISC; where are those speedruns? I can't find any place on that website where the event is been held.

I really like how your car looks! It's very simple, but I like it

Ohhh, and the sound if you give full throttle, that's just awesome, I really love the electric speedrun sound

ISC is relatively new, their first event is coming up April 29 & being held at the Encino veladrome. An additional event is being planned for later 2009, location TBA. I'd watch the site if you're keen

Yeah the Rustler is simple, a good one to learn on I guess. The sound's good isn't it!

Encino Veladrome is somewhere in the US, right? (google) I would love to see a speedrun event in real, but it is too far away from me to travel. (Living in the Netherlands, Europe)
Do you maybe know some other speedruns events maybe, that are held in Europe?

To go ontopic: How do you think to reach the 100Mph? With this setup, or a other one?

ROSSA

This is the UK site. AJ Lovering (ziggy12345) founded ROSSA & he'd love to hear from you I'm sure. They have events planned for 2009 also

I'm confident I'll get 100mph with this setup if I continue tuning. I've only really had a few runs, so there's another level or two of development left. I don't have any data recording yet nor am I using a gyro, or any motor timing changes which leave a lot of room IMO

Many thanks for the site! I'll look around at that site, looks good.

Ok, I'll wait till you get some updates. Goodluck!

87.0mph today...with a crash caused by a fist sized hole in the road

I've installed new steel yokes but until parts arrive I'm still running the stock sliders with cable ties around the ends, they performed without failure today

Edit: I did use a cheapo gyro today also but I believe it was to sensitive and may have reduced the speed available?

I'll post the video soon

Raze ST Truggy · 04.12.2009, 09:59 AM

Almost 90mph, what damage did the crash cause? Loose any vital parts? I hit a curb so hard motor first last week that the R/X stopped working. Good luck on getting to 100mph. How fast do you think this thing will go?
