Maximizer X75 Maxx adapters for Nitro Stampede

[Rusty4Ever]

I realize this is a pre-sale forum; but I ordered these today for my electric Stampede today (with Nitro front spindle conversion).

Now it shows item is now unavailable; did my order cause this? I've not gotten an email response yet.

I specified in the comments I wanted the Nitro Stampede version to fit the Maxx wheels, & I believe it's correct for my application; tho it's electric, I have front Nitro spindles & have done the "wide" conversion to the front & will be using RPM's StableMaxx offset rims. I should be fine right?

The picture is confusing to me, I see the rear hex drives clear enough, the front bearing/spindle is less clear; do these fit inside the Maxx wheel hex??
EDIT: On Maximizer's website, it appears the front pieces hold the 5x11 bearings on both sides of the Maxx rim so the fronts spin without wobble. Hope I get sent the correct Nitro part, will probably want to get the Fastlane extended chassis too. :024:

Thanks for any help with this. Great site/products by the way :027: Wish I would have found it earlier :007:

Yes your order caused them to go out of stock. You got the last set that was in stock. You should have gotten an email from the store with the order receipt. You will recieve an email once your item has shipped as well.

Okay Thank You. Excellent then, so I assume it's the Nitro part I needed & I have my Stampede "equal" arms/Stablemaxx rims ready to accept them.

Now I just need a good brushless setup/alum diff to push the extra weight :027:

Thanks again :003:

Well this is the right place to get the right brushless setup and the steel diffs.

I have the Lehner 4200 and MGM 80 in my FLM rusty.

I have the Lehner 4200 and MGM 80 in my FLM rusty.

I see the steel diff, nice, I have alum idler in now.

MGM 80 looks good too; I converted my old Rusty to a Stampede after I got my Tmaxx (I love the 3hr bashing sessions, from motor to servo cover nothing is stock, full rollcage, it's a tank). So I'd like to setup up the Pede for quiet "neighborhood" bashing. It was good as a Rusty with alum hubs & 5x11's at the wheels. BMS620MG on 6.1v (regulated) to turn, end points set.

I run 7-cell packs (2100-3300's, 23-33amps), as that fits my planes too, 12ga, deans, build my own 5A BEC's (to run BMS servos usually), & use inductors to rid any glitches (Hitec FM gear, but BL helis make "e-noise").

Lehner 4200 seems a popular choice, it's currently out. Good quality at a bit higher price than say a Feigao...both seem fine to me.

I see the Feigao 540 8S is 81A (can the MGM80 take this?)

Also I've heard the 380C's spool up faster (like a 8T,7T,6T) but the 540 has the torque (maybe a 380C-6L?, I don't see many L's or XL's here). Kinda of a toss eh? But the 380C might be more efficient (except for my Maxx wheels maybe). I'd like to stay under 80A full tilt (if possible) and still make the Pede with Maxx tires jump around for awhile...

Current setup with Masher 2K's is Futaba 330CR clone ESC (B1006, $30) and Orion 17x2 Method R ($15). Bashing hard (full throttle/brakes) I get 10mins on 7 GP3300's. Like to at least keep this runtime. Should be easy with the right BL motor right? Except this time I'm pushing the big Maxx meats so I probably just negated (if not worse) the BL motor efficiency I would get on my NIMH packs... then again the Maxx wheels don't seem "that" much heavier than the M2K's... haven't weighed them yet.

In short, 8-10min runtime (7 GP3300's) would be nice without having an overly hot motor/esc, with at least 16-17T brushed performance, using, & without killing my current batts; is this possible?

The basic 4200 would be a real nice motor for you IMO.I can get around 8 mins from mine from 8 gp2200s so this will easily get the runtimes you want with alot more torque than a 15T brushed.On 6 cells the torque and acceleration is still there just not the speed,you'll see high 30's quite easily on 7 cells.I get 45 mph(gps) from this motor in a light xxxt on 8 cells.I'd go with a 540 for the bigger tyres,it'll like the load better.The 4200 is a great motor to have for 1/10th stuff,will run from 6 to 10 cells NiMH or 2-3s lipo quite happily.

Thanks for the reply.

I've heard it takes around 8cells tho for the 4200 to really wake up. I've got only 7's, & they aren't exactly new either. My info on the 4200 is that it's a "up to 600watt", 45A BL motor. Unsure of it's "size" as well.

I know the Feigao 380C-6L is 1/8" shaft, integrated heatsink, & about 4900k/v and 69A. Half the 4200's price, no doubt the 4200 is higher qual. I've been told this longer arm 380C can torque similar to the 540S's, at a higher spool up rate. The BK7018 ESC is attractive to me because of price, & I don't think I can even go over or near 70A on my batts (unless replaced).

I did weigh the Masker 2K's on Traxxas rims vs T-maxx tires/foams on RPM Stablemaxx claw rims, barely 3ozs diff per wheel added, I thought it would be more, thankfully it isn't & my brushed motor can almost manage it without much trouble.

I just like to jump & bash my Stampede, so I gear it for quick bursts to hit a ramp; topspeed isn't important as I don't use it for that, 25-30mph is plenty & with 5.75" tires I gotta gear down on Stampede's trans anyway to get the accel... so a high K/V fast spool motor I'd guess is helpful if the longer armature can make the torque.

Well you can't argue with the price of the 380c,plus i think they're in stock,4900kv would be as high as i'd go(don't think these are loaded kv values though).One thing i would say though is i personally don't buy into the faster spool up theory in a 2wd vehicle,for touring cars i can see the advantage but in a ST unless you're running spikes on grass you'll never have the traction to accelerate as fast as the 540 can spool up.partly why i suggested the 4200 is the runtimes and also the torque,the take off is quick from 6 cells.Having said that i think the 380c could work very well on the lower gearing you're talking about,i think a lower kv 540 would take off as quick though geared for the same speed(on a higher gearing).Remember you can gear a slower turning big motor higher so it doesn't necessarily need to spool up as fast to have the same acceleration and top speed.Just food for thought.

1 batter bar. also, i would cetainly go with ib's.

Okay, IB's are good, kinda figured that. Thanks for the $.50 per bar info.

How strong are the IB batts? I mean with 7 sXs, will the BK 7018 still cogg if I set my external BEC to 5V? i.e. can the 380C-6L (69A peak I think) pull down 7 charged IB 3800's to 6V (need a volt to run my BEC) in "normal" use?? I expect the volts to droop as batts get exhausted.

EDIT: Anyone know if the $.50/bar would be the same as the "larger than deans" that are depicted on BB batts?

You shouldn't have any trouble with the LVC on 7 cells. The newer(year or so) warriors actually have a better voltage cutoff threshhold than the older ones. I tested a 9920 with a 6 cell stick pack and couldn't get the dreaded "cog" until the very end of the discharge.
Also, all the warrior car controllers have reverse-just a matter of programming.

Thanks Mike,

I'll make my "new" 3600+ packs all 7cell to try to keep that voltage up. I think I need it to push the heavy Maxx tires on the Stampede/380C-6L (just gotta find the right gearing). Many say the old/flaky software in the BK7018 isn't so smooth below 8cells (tho some say cheap 6cell 2400's were smooth).

I just want enough cells to hit 25+mph, enough to hit a ramp in the yard (short take off), anything else is gravy for me. My 16x2 Epic Intense gave it a good shot on 7 GP3300, but the 13T+ ESC de-soldered it's factory battery wire from the heat. Still works, & thermals, they just set the thermal too high & used 14ga. I think BK thermals at 110C, I'll probably add a cheap fan, easy enough.

I'll use your sticky thread for programming the BK ESC and turning its BEC off; that's where I learned about the convenient motor reversing too, thanks. I don't think I hooked up 3 BL wires yet that spun proper direction, some luck eh? :027:

As nice as that jumper is, doesn't BK come already with 3.5mm gold plugs, so motor reversal would be simple anyway. I think use of the plugs is a BK warranty condition. Not like I'm racing or want to solder, I happen to like easy disconnect for service.

Nope, the warriors do not come with plugs attached except for the connector to plug into the Rx.

Finally ran the Feigao 380C-6L on the BK7020 on 7cells (using homemade BEC, I do have to set to 5v, or I get cogging on elderly GP3300s). Soldered to perfection, it's awesome even on the huge wheels. Temps get to 60C on motor & ESC during speed runs with body on and 84/18 gearing. Ordered a Swami wheelie bar to protect the motor. Seems to be ~40mph on the Maxx tires... silly fast... Seems like an 8T brushed.

Can use current batts now & bettter ones later. Tall grass, or anything else, is no problem; bottom torque requires a wheelie bar.

My T-maxx is out-of-service (620MG Blue Bird steering servo keeps cracking cases on Moab 40's, & I can't find the newer BMS black cases), so I'll be running brushless for awhile & charging batts! Great to have an electric as strong as my nitro for when I can't get to the parks.

EDIT: I forgot to glue my tires... made a big difference, to say the least. I think I'll mod my BEC to allow different voltages, 4.8/5.0/6.0 for different packs and allow passthru batt voltage when batt sags below the setting (& beep or something then too, so I know, cogging is nearby).

Thanks for the great products & advice :027:
