wow, lol wouldn't want that:)

Well, two weeks later and I finally get to drive my new truck.(barely, its raining) There is no room to spare with these packs.(7.4v 6000mah) In fact, where the wires exit the packs, that posed a problem for getting them in the tray. I had to make an opening in the side of the trays for the wires, otherwise the packs would not lay flat. Also the little clips that hold the wires on the side of the gear covers had to be trimmed off or the pack would hit them as well. Thats why the wires are going over the moters instead of along the side.

I'm not so happy with the wires hanging out the side of the trays as it slightly buldges the body and potentially is in harms way from debris.I could always make the notches on the inside by the esc but that was going to take way longer and it was 2am when I was making initial fitment. I was a little dissapointed that maxxamps does not mention any fitment problems like this on there site, oh well.

The LVC blinks 4 times to indicate the the 4 cell configuration, so I guess its working right. A full charge took a bit over 3 hours @ 2.5amps. The initial voltage was 7.4v and now reads 8.32v Can't wait for some dry weather to take it out for a bashing:027:

looks good!! keep us posted on the performance please.:027:

yeah i wonder if there will be any problems? Keep us posted

Looks tight!

Should be a gradual performance increase!

Should Run Well! Good Luck!

I've gotten about 10 minutes on the truck. It stopped raining and I ran it 5 minutes in a friends gravel driveway. I ran it on some wet concrete and in the house on the carpet.

Up to this point I have never seen a nitro truck run nor have I driven one. I have neither saw a stock Emaxx run on lesser batteries nor driven it that way either. My only real experience with a r/c vehicle is a Associated RC18T. I have one. It was stock for a while, now its brushless on 3 cells, mamba 5400. From this perspective Im a little "spoiled".....ok maybe a lot. So what did I expect from this truck? Really only what Ive read.

So, I expected wheelies and perhaps in 2nd gear(base off the maxxamps site). This does not seem to be the case, but I think that is mostly because of tire slip. But even on the carpet in the house It wasnt like I could wheelie at will. From a dead stop or reverse to forward yes. 1/4 throttle and punch it, not really. But again I think the tires are spinning quite a bit. I don't forsee 2nd gear wheelies with any tires on any surface once its rolling, I could be wrong though.(yes, the tires are glued)

Had I not had a brushless mini I would prolly be a lot more excited. It will pull wheelies or backflip nearly at will, regardless of surface or tires or speed. Its just stupid power and is so small and light. This definatly is going to lead to a brushless monster experience in the future.....Don't get it wrong I do like the truck and am happy with it. Just not quite up to the hype as far as the batteries go, but I have a lot more driving to do before the verdict is in.:dft012:

are you using stock e-maxx tires, i bet with some soft tires and something with a pattern like the bowties it should wheelie in 2nd. and is the peformace good?

Is the truck new or used?
I dropped my gearing down a little.
I also ran a better spring on slipper as well.

Yes, they are the stock tires. I don't have anything to base the performance on... like I said in my previous post. Having said that I think its pretty decent. Who knows it may be great to others or not so great. Its not a brushless 1/18th scale thats for sure.

yea, like leroy said drop the gearing it will wheelie, i remember with my old maxx runing 7 gp 3300's i droped the gearing to 16 or 18 i dont remember BUT it was shure a hell of alot of wheelies.:)

yea, is the truck new or used?

Mike, the E-Maxx comes stock with 18/66 gearing...

then im sorry it must have been 16T then.

So the easiest way to change the gearing is to change the spur or pinions?

It depends on what you have, what is available, how much you want to change the gear ratio, etc.

and slipper.....the slipper can help a bit also.

Dropping a tooth on pinion is not hard. You would loose maybe a mph or 2.
The torque you gain is alot better though. Seems like the motors run cooler
as well though. Cooler motors make them last longer.
IF the brushes are bad in the motors the power will suck.

that goes with about every brushed motor out there.

Hmm thats odd, but i remember running in my basement, i gave mike my revo responces (he was using stock maxx tires) and he started to wheelie like hell!

Tires make a big difference, those stock maxx tires are junk imo.

yeah, they weigh soo mutch(stock)..tryed the reponses...WOW!

Sounds like what I might try, dropping a pinion tooth or 2. How do I adjust the slipper? Is it possible the brushes could be bad, I just got it outta the box with only 10 minutes of driving total?

ONly 10 minutes of driving i doubt they bad.
If you haven't tighten or check the slipper it is a good possiblity that may be a problem. You don't want to go to tight cause the stock slider to the wheels
well ring off.
The slipper is right under the cover where the motors are. It tells you in the manul on it.

OK, I just ran it on the carpet again and its definately the slipper clutch, not tire spin. In fact if I hold the truck and give it gas the tires stay put while the motors spin so the clutch is way out......from the factory:031: . Im gonna try to firm it up. The manual says it should not slip under acceleration. If thats the case it will pull wheelies like mad.

I made some adjustments to the slipper. It was set way conservative. Tightened it fully and backed it out 5/8's of a turn(manual calls for a 1/4 out) It wheelies now, and in second gear:cool: At least on the carped....its still raining:019:

Yep, Raining here too! Better than snow in my opinion.

Its finally stopped raining and I took it out in the driveway. The surface was still wet. I have a mix of asphalt and aggragate. Woohoo, this thing is FUN. Glad I got a wheelie bar! Cant wait to take it in the grass and off road Im sure it will be great.

We have snow now! They are saying 1-4 inches for Chicago. Bummer!

I saw somewhere you can get ski's for the front wheels. 4 sets of artic tracs would be cooler though.

That would be cool!

In the pics above is the LVC going to see voltage for both packs or just the pack on the bec side?

From both pack's, it is connected to "neg" side of one battery and "pos" of another, middle point (other "neg" and "pos") is shorted via ESC.

This thread is a bit old, but I'll update it anyhow. The emaxx is still running fine on the 2s2p's and the motors are holding up. The truck has taken a beating however.:mdr:

what LVC brand are you using? and is it for 4s or 2s? ofcourse 4s, but Novak sells 2s and was thinking of buying two 2s. I don't know. help!

Read my tutorials page, the lvc section will have all the info you need:

:smile:

thanks Neil! big help! what would you recommend for my stock evx emaxx?

I like the buzzar type alarm that plugs into the balance plugs- 3.0v per cell stock setting is about perfect. For you, a 2s version would be correct- just solder on the white connector or solder the red & white wires directly to the battery plug coming from the esc (BEC side, see bottom). Once the battery starts dropping off in voltage near the end of the run, it will buzz more frequently:

There is also a version with a red LED instead of a buzzar- mount it somewhere like in a window on the truck so that you can easily see it- the more often it lights up, the more discharged the lipos are becoming:

I have one of those and it does work well- bright LED. Dont use it anymore though as my setup is rather different compared to my old hvmaxx powered setup.

If you want a more adjustable lvc device, take a look through the hobbycity website section below:

Lots of interesting recorders and monitors.

To wire up the 2s lvc, follow this diagram:

Enjoy :smile:

so you wouldn't recommend an actually cutoff? More of visual and hearing to notify yourself that the batteries is below 3.0v huh?

http://www.hobbycity.com/hobbycity/s...itor_2-8S_Lipo

I like this, is it too much?

Thats one of the best they sell- very adjustable, and $30 isnt that bad, especially since you can use it in other models with larger lipos in the future.

Whether you use a true cutoff like the novak 2s smartstop, or just a buzzar/alarm is personal choice really; I dont really like the idea of a hard-cutoff, I'd rather be warned that the battery is loosing power so that I can bring it in top my feet, rather than have the truck grind to a halt or start acting erracticly whenh you hit the throttle. The adjustable cell voltage of the alarm above is beautiful though, as is the logging feature for max and min voltages during the run- not that the stock emaxx should put much strain on the lipos, but all the same..

if i were to use that, how would i come about connecting that onto the EVX controller? looks like a balancer tap is needed. My hard case lipos have no balancer tap, only when I charge them, I use the balancer tap.
