we need to step up our brushless mts
 

Guys we need to get our brushless mts going a little faster b/c the nitro guys are right here with us. Man this guy hit 65mph in his revo:surprised: I didnt think it was possiable :neutral: . The fastest e-revo I have seen is like 62mph. What gives. We cant have this happen to the electric community. We are looked down on buy the fellow rcs as slow electrics and just when we start going faster than them ,THIS HAPPENS http://monster.traxxas.com/showthread.php?t=440526

His jato hit in the 70s too. Dang I guess when the economy here picks back up I am going to have to beat this!!!!! Some how

If any of you has a mt thats faster please let me know so my world of electrical supremecy doesnt fall like a house of cards:cry:

My xxx-t with my lehner basic on a 4s lipo was faster than his jato but havent seen a mt faster than that.

I've had my e-revo at 65, only 62 on video though.. this was with 6s lipo and my standard race gearing I run w/ 4s. If I would have dropped from a 58t to a 54t spur I would have easily hit 70mph. I would do it now but A) I sold my hpi phaltlines B) sold my 3s lipos C) Its setup for dirt racing now :)

jzemaxx was getting something mt over 80, IIRC.

I am now feeling a little better. Glad to hear that electrics are still faster even in the mts. If anyone has a video or can make one I would love to see it. Just so I can put some smack down on a friend who showed me that ideo. He is a nitro fan and in my email there was a "I told you nitro was faster" comment in there. I cant have that thrown at me without some amunition to fire back

Look up "Nic Case". You will notice that none of his builds involve nitro, and all beat 100mph...

You nitro friend has his head in the sand...

do you guys who ever go around 70 in your revo's do u have problems with keeping the front end down?

I plan to hopefully break 55mph in my E-Warhead on 6-8s lipo. All depends on if I can find a new job here soon. Also need to buy my first car so it may be awhile...

You need a nice runway and a very smooth throttle.. a little weight maybe needed if your truck has a tendancy to lift in the front. A few important things to hitting the top speeds.... phaltline tires, and lower the suspension so your just about scraping ;P

A 1515 1.5d on 6s will easy hit 70mph, you wouldn't want to run this all day but the Neu is more than capable of showing off and speed runs w/o issues. Again 22/54 in the e-revo will get you the gold, can shoot for more if you want but be careful with temps.

I think Lehner's are more suitable for high-speed applications. They heat up less with tall gearing.

Neu's would be fine with speed runs. But in general for speed runs you'd want to look into a 2-pole that is quality such as a Hacker.

Or a higher pole count and compensate with gearing.

Yep that will work to.

put "fastest mt" in a youtube search and see jzemaxx's 80+ mph xtm mammoth

After watching that video, I don't see 65mph. First, the guy holding the radar is MOVING IT. It is suppose to be 100% still and not turned with the car. A lot speed can be added there. Second, it is a Radar. We all know how "accurate" those things are. And last, just looking at the truck run looks to be a 45-50mph truck. Still fast, but no 65. I would like to see the truck with a GPS strapped to it. Electric are still king!

if you look when the guy hits 65mph he is holding the radar straight. not moving it.

would it still affect it?

also, you are right... it does not look to be goin 65. but the radar is more accurate then our eyes.

It's still a dang fast truck.

The radar should be on a tripod perfectly still. As for being more accurate, not really. Radars, especially cheap ones as that is, are extremely inaccurate. It looks like a 45-50mph truck. Still plenty fast, but not brushless speed.

I'm getting ready to race one of my friends T-maxx thats all maxed out in a couple of weeks in our work parking lot. I'm going to try and make sure there are no long stretches because I think he is good for over 60mph too. I think I can take him on the sheer torque the XL motors have on startup. I have my 7xl running 41mph with 20/68 gearing and the SPC 8000mah packs.

I wouldn't worry about Smoker's beating us flashlights anytime soon, we got the advantage. Nitro's are mechanically limited by fuel and burn rate within the engine, unless a better design is brought out, Possibly 4 strokes or diesels, Nitro will never dominate the Brushless/ lipo setups we got. With the 4 strokes, there will be a learning curve, much like brushless/lipo, to optimize performance. Till someone does something radical, We are safe from losing ground to nitro's

Before dumping my T-maxx I thought many times of going 4-stroke but was laughed at and told it wouldn't work. I didn't have the ability or connections I do now to make my own chassis and what not so I gave up. IF I ever got back into nitro I would go 4-stroke only. Those engines are so much more reliable and easier to tune and keep in tune. I think 4 stroke would be a lot like low KV BL motors in where you would take advantage of the torque and not the RPM.

I also think that most claiming their nitro monster trucks break 60 is extremely wishful thinking. When these guys do it properly and strap GPS's to their rigs then come up with repeatable runs at these speeds, I will be impressed. Until then.......

Edit: dbl post.

Not to mention the weight and heft a 4 stroke would bring. Sure, low end torque but no RPMs so the gearing would be very limited. You would probably need to design your own gears, maybe make some spurs into poinions. If I were to build something with a 4 stroke, it would be one of these motors.

Oh it would require a custom motor mount, custom chassis, and custom gears. I originally did some preliminary investigation and at one point there was a .40 conversion for a t-maxx chassis but I was thinking more of something in the .90 range.

I would like someone to get real inventive though and do a turbine 5th scaler. One could use a helicopter style turbine.

4 stroke nitro ? Link me

I assume this has been around for big planes, as I spend hours watching them on the weekend wondering how the nizzle they fly, but in a 1/8th buggy application it seems large, I was thinking like my compagnucci car. a 1/8th with electronic ignition... then add 4 stroke

My bushnell radar gun if not on a tripod will very its speed too(I didnt even think about that) I will do some of the youtube searches so I can slam my friend nitro clames in his face! I have never seen a nitro mt go that fast(all the ones I have seen are slow) Even my friens lrp spec 28 powered lst is slow. My brushless lst2 smokes it even on a 4s lipo, even when I had it set up to run off of a 5s batt. I even brought it to the lhs and smoked all the nitro guys there too. Thats why I was so amazed to see this guys 65mph revo.


Thanks for the help and I am now off to find some electric speed videos

All this radar talk.. this is why I always use GPS; mine happens to be the garmin etrex Venture Cx, awesome little unit, very accurate and small enough to strap in with out issues. The only downfall to a GPS is if you don't hold the top speed long enough it may not register, so any reading you get on a GPS you know is on the money.

kyosho used to make a touring car series based around 4 stroke engine use...if I could find one I'd so love to have it..and it would probably end up being my 1 and only self queen

its a fast truck but our high voltage setups are still faster...

>:-) Nitro will never beat us. I just invented that smilie.

After looking at those 4 strokes IDK if you could ever gear one high enough to get any speed. With Max RPMs being about 12,000 I think the only way would be some kind of direct drive

if you count truggies.. i went 58.3mph yesterday with a Cen Matrix tr....

1515 1y
5s zippy lipo
20/66
i could probably get 65 from it.. timing was at 0* and gearing was limited to my motor mount.

It took 2 nitro motors to get a truggy to 71mph. So I say your doing great
