my UE SuperMaxx

[ClodMaxx]

i'm still tweaking the settings on my MM... had it out tonight for about 10 minutes, and brought it back in to tweak them some more. temps didn't seem too bad, but i didn't push it at all - my goal tomorrow is to see what she's got. if it gets too hot, i'll gear down... i think fans are band aids. right now gearing is 51/15, but i have 5 other mod1 pinions - a 12, 14, 17, 18 and 20 that i can go up or down from, based on temps.

from the little bit i've been driving it so far, the MM/Lehner combo doesn't cog at all... i can crawl pretty slow too. i'm not sure what it'll do at higher speeds, but so far it seems as smooth as my old sensored HV 6.5 system.

Scot your truck is absolutely beautiful. I would definately run it, but carefully.

[suicideneil]

If only you could breed from it, 'cos that is a thoroughbred machine if ever I saw one.

[ClodMaxx]

thanks again mark and neil.

i just got back in from about 15 minutes of bashing around with her. i ended up taking the MM settings back to factory specs, except i put punch control at 60%.

i'm amazed and confused at the same time.

this thing handles like a dream. it blew me away. it's now so long and flat that i took some turns that i thought for sure would put it into a horizontal barrel roll. i had the proline steering rack for so long that i never realized how good steering could be - the UE gen IV servo saver is worth it's weight in gold. and wow do those mulchers bite! they're definitely my favorite tires so far.

now, the perplexing part. the MM definitely heats up when farting around at slow speeds, which i knew would happen. it actually cooled off after doing a few speed runs. but it doesn't have the speed i thought it would. i didn't have my GPS attached, but i would guess it was going roughly high 20's in grass. no where near the calculator's specs of 40 at that gearing. but... there was absolutely zero cogging.

i have a feeling the custom rear driveshaft is rubbing on the bottom of the chassis - i'll have to pull it out and grind it down. after about 15 minutes of speed runs, the MM temps hovered at about 135, lehner temps were at about 105, and the batteries (matched ni-mh) were around 110. from a glance, that's telling me (barring the driveshaft problem) that i'm just a bit overgeared...which doesn't make sense. 51/15 should be conservative. but it's probably just that the MM isn't designed to handle the motor, the number of cells, and the size/weight of this truck. i may have to invest in a higher powered esc... darn it.

the batts weren't fresh, so i'm letting them cool down and will recharge them for a run later. i'll also pull the rear shaft out to grind some material down.

so, overall the first real run with this has mixed results. once the esc bugs are worked out i'd looooove to get this on a track - the handling just blew me away!

[ClodMaxx]

something is going on with the drivetrain. i pulled the motor away from the spur, put it on the floor and gave it a good push. it won't roll as easy as it should. *sigh* i hate this part... i may have to tear it down to see where the resistance is. i can't tell by looking/listening.

Does anybody know if UE is going out of sale? The reason I ask is because they are out of stock on everything except shocks, diffs, and servo savers. I need to buy some of their 6mm cvds...anybody know where I can get some?

UE has actually added stock lately - the gen IV savers were out, and now they show in stock. I visit UE forums frequently looking for the parts I'm missing for my Pred and SM in the BST forum. I can understand UEs point of view - he made a run of monoblocks earlier this year and has not sold them all. Why should he go to the expense of making new cvds, chassis, diffs, suspension kits etc when they don't sell? Lots of talk about new run of super sixes for trans - that never happened, prob never will.

I think he is just selling off NOS and when its gone, he's done. My 2cents worth.

ClodMaxx - Sorry to hear of the troubles - if it was too easy, you wouldn't appreciate it the way you will when you get there!! Maybe its just a wheel brg or something simple.

Nothing wrong with a set of blood red wheels with some flesh shredding Mulchers.

I see are giving the 8 shock set up a try on this JurassicBeast too. Cant blame you there.

Dayum Scott, she sure looks great. Such a loooooong ride, Kinda like a size16 shoebox on wheels. Can you imagine what those GIANT tires suicideneil runs would look like on your truck too?

That MambaMax doesnt deserve to be in your truck imo. That's like a big ole nasty printed Big Block with a 2-barrel carb. It just seems too basic. Dont sweat the little kinks too much. If anybody can figure them out you can. You know you like it. And when you finally get her in the sweet spot there will be nothing more satisfying. Yeah, I'm still jealous.

I have been away from the computer for days. Sure was nice to come back from vacation to find this purdy behemoth.

[suicideneil]

Now you mention it, I think the SM would look seriously mean with some Jumbo sized rubber mounted on each corner, but at 1lb each, they arent light wheels/tyres. Thats what makes my poor HvMaxx's life so hard, trying to gear for a 12lb truck isnt as simple as with a powerful Neu/lehner motor. That said, you should get there in the end.

As for the sticky drive line, I would say remove the tranny, then spin the front and rear wheels by hand to see if either is a bit rough/sticky etc- the wheels should spin down nice and gradually, not abruptly. You've stripped the thing down so many times it should be second nature by now I reckon....

[ClodMaxx]

doug - welcome back! hope you had a relaxing vacation.

i have those same tires, neil - got 'em for my stealth. i pre-mounted them on the SM and it does look mean, but you're right - they're hefty! i should have snapped a pic before i took 'em off.

more mixed results. this morning i threw a matched 7 cell pack on the discharge tray, and it fried. i had all the +'s and -'s lined up - i have no clue what happened. practically brand new, too. so - it's time to take the plunge into lipo. maybe some trueRC 8000 packs. i have to get a balancer too, so i can continue using both my Ice chargers.

the good news: i tore the back end off (separated it at the bulks) and there are wear marks on the custom driveshaft. i spun the center drive cup by hand and the rear wheels are smooth...didn't take the front off as i know i checked those too before putting it all together. so i took the monobloc off, and threw the stock titanium rear center dogbone on. once it was back together, it rolled quite free. problem solved. and now it's more 'shortbus' in length... lol.

the only batts i have is a pretty well used matched 7 cell set, so i'll throw those on the charger and see what kind of mess i can make today...

[ClodMaxx]

sheesh, my luck is getting better and better. one of the two older 7 cell packs has a bad cell. i have no packs left to do any testing.

looks like i'll be going lipo sooner than i thought.

[mkrusedc]

Scott you will love the lipos performance. You might even be able to shave a little weight off of that beast.

[RCShocker]

MuchO relaxing Scott.................1st vacation in over 14 months.

But you are just confusing me with all the battery stuff.

So I'm gonna throw this out there? Do you/will you have any loose IB4200 cells that are worth a hoot. I had a cell vent on me last week.

I can not imagine your truck being shortbus'd. I bet that sucker still has the streeeeeeeeetch limo look.

[ClodMaxx]

i just spent the last 8 hours doing some power-studying on batteries. almost went with a trueRC order, then trakpower lipos looked good, but i finally decided on a pair of a123 racing packs (each pack is 2s2p, 6.6v, 4600mah) and their hypersonic charger. had i gone lipo, i'd have to buy balancers to add to my Ice chargers, the lipos, and a LVC. now i can sell both of my Ice's since the hypersonic charger/balancer will charge in about 15 minutes.

mark - the weight isn't bad at all. right now without batteries it's at 10 lbs. 8 ozs. That's not great, but it's not bad considering i've got an all-aluminum rig with 40 series wheels/tires, a wing and aluminum wing mount, and a 5 cell rx battery.

doug - i'll send you a PM on the remaining IB packs i have.

the batteries and charger should be here by this weekend!!!

[suicideneil]

A123 cells, excellent choice. But- 13.2volts sounds a little low?...
