First Run: 80a HW Rustler

[Raze ST Truggy]

I finally got around to mounting the large Hobby Wing 80A ESC in my Rustler. I left all the settings at default and did some test passes with a Medusa 36-60-2000 on 2 x 2S 4000 mAh lightmax 25C hardcase lipos.

Initial thoughts are that this ESC is smooth and powerful, but I need to get a bit more time in before say for sure. The spur is a 40T and I ran a 20T RCM mod1 pinion.

I only got about 10 minutes of run time, but most of it was at a high rate of speed just trying to keep it pointed straight. No crashes, no cartwheels, no jumps, just a large open parking lot zipping from end to end.

The run ended when the diff exploded. I'm not really sure what happened, the car was at the other end of the lot and just stopped going when I got there everything looked fine, but the car wouldn't move. I already have a steel idler gear, but had stock non-VXL diff. I say had becasue all thats left inside it is stripped teeth.

Up until the diff blew up it seemed smooth and temps were all in check. I had a VXL diff kit in the TRX spare parts bin so I should be up and running tomorrow, but I think rain is in the forcast.

I'll post some pics in a bit. And some more thoughts on the HW 80A ESC after I have some more time with it.

Here is a pic of the setup, I'll get some vid when it's back togeather.

Nice! A 2000kV Medusa on 4s seems way too much power in a light rusty. That's enough power to move a 1/8 truggy around with ease!

Any plans on converting your Raze ST truggy? I'm looking to do one.

Funny thing is that I had the medusa/ MMM on 4-6S in my Raze Buggy and it was a blast. I am thinking about a 50mm Medusa for the Rustler , I just want to make sure it's enough. I'm looking at the 3300kv, but am not sure about temps with the heavy FLM chassis and beadlocks. If I leave the 60mm in the Rustler I'm going to buy a 70mm For the Buggy.

Yes, I have plans to convert my Raze ST Truggy. It will be powered by a MMM 2200kv combo, or a MMM/ 80mm 1600kv medusa. I will have that done as soon as I recieve my order of Kydex to make battery boxes trays. I used mikes Mount in the Buggy and I'll be using another for the Truggy, it was/ is a perfect fit.

What mount did you use? I don't see a mount on Mike's site for the Raze or Raze ST.
Oh, if you make battery trays, I might be interested for the Raze ST.

How much does your rusty weigh? There's quite a few E-Savage guys running the 3300kV 50mm Medusas on 3s with no probs. Temps seem to run about 140F on the motor which seems normal for Medusas. It sounds like you like a lot of power so I think you'd be better with either keeping the 2000kV 60mm on 4s in there if you don't think it's too powerful, or getting the 2200kV 60mm on 4s or the 3100kV 60mm on 3s.

Wouldn't the 2200kV or 2000kV 80mm Medusa be more equivalent to the MMM 2200kV?

I bought the 80-1600 becasue I thought it would be a good 6S motor and I already had a MMM. Then I went and bought a MMM 2200 combo so in all reallity I'll probably try both and how they are.

I think I'm going to buy a 50mm when I order another raze mount. I have not used the mount in my truggy yet, but I think it will work fine. Gearing might be a little more limited though. When I convert a Raze Truggy I'll post up how it work s out.

Brian,

Can you link me to the Raze mount on Mike's site? I was going to ask him if he could make me one (like I did when I converted my ST-1), but if he already has one, that'd be much easier.

I just ordered a Raze ST from Tower and a Raze buggy 46T spur for more gearing options (hopefully it fits). Can't wait for it to arrive!

Let us know which setup you prefer, MMM 2200kV or Medusa 80-1600kV.

It's not on his site, I e-mailed him about it and he told me that he had made one for someone last year and to just order a Kyosho mount and write in the details that I wanted a mount for the Duratrax Raze. I would e-mail him first just to make sure that it's not a problem. And He might have some more insight as to how it fit's in the Truggy. I've got the 46T spur in my buggy with a 12T mod1 RCM pinion and the thing is an animal. It's down currently so I can add oil to the diffs and check over everything else.

Towers deal for a Raze ST Truggy for $199 is really good. My nitro raze while to some is "not worth the money", is an awsome basher. Out of the Box it went 39mph per GPS and took a beating tank after tank. Only failures I've had were the crappy servos that duratrash put in the truck.

I'll be sure to post up which combo I like better and why once I get some time on them.

The diff itself was fine so I put new gears/ outdrives in it and 100k lube. Lipo's charged up, I took it out so show the girlfriend how "cool" it is. LOL. After less than 10min the diff ate itself again. This time it was the teeth on the ring gear, I reused the non-VXL one.

Now I've got it back togeather again with the VXL-Diff (steel ring diff gear). This time I only put a mix of the 100k that transfered from the diff and 30K lube. Diff is much smoother now, but I know it will be leaking out soon.

This thing is fast, the parking lot that I'm running it in has a lot of sand in it from the winter, so I think it will be a while until I get some good speed runs in. All I can say is this combo is ridiculous when it comes down to power.

Thanks Brian! I emailed Mike so I'll see what happens. Hopefully he can still make the mount. I don't see why it wouldn't fit the truggy...I think the center diff housing is the same.

Yeah, the Tower deal was too good to pass up. I got an additional $38 off too! I think the poor reputation Duratrax got over the years is from their entry-level cars/trucks that weren't up to par with their counterparts, albeit the DTX vehicles were lower-priced. I think their higher-end vehicles are quite good, hopefully. I've got a Firehammer MT also and I like it a lot, although I haven't had much time to run it. One good thing is customer service seems great, especially since they're associated with Tower.

Sounds like you have an insane amount of power there for a rusty!

Holy smokes that is a big esc! Nice mounting job though.

He just made me one for my Raze st. I know its not the best but for 165.00 shipped from tower couldn't pass it up.sold the nitro stuff for 90.00 on ebay and had just 75.00 in the new roller. I'm still running the 62t spur also.

Hey, I saw you have the rustler in your sig still... Might wanna change that now that I have it...

[Raze ST Truggy]

I made a jumper so I could run a single pack instead of two and ran the car on a Zippy 4S 4000mAh pack today. I case I haven't made it clear yet this car is an animal. I really think that if I made the bottom of this FLM chassis total flat the car would indead fly.

Right now by the speed clac it's geared for 72mph, but I haven't gps'd it yet. All I can say is this thing hauls butt and everything stays cool.

My early afternoon run ended with a high speed wheelie turned roof skid that ended with a hard hit of the motor into a curb. The ESC was 3M double sided taped down, but the impact with the curb was enoug to break it off. ESC was fine, but the RX brok. I replaced it with a AE XP3D tx/rx and ran it again.

This was one of my most fun R/C car runs ever. I hit the large empty parking lot across from my house, and not 5 minutes into the run a cop show's up at the other end of the lot (no uncommon, my girlfriends house is 2 doors over from the cop shop). They were cool and stayed all the way to the end of the lot giving me the whole thing to run in. I ran it around for about 10min and decided to stop before I broke something. I need to make a new ESC mount and a battery tray for it before I put anymore time on it.
