Plettenberg Maxximum Specs

[sugs]

Anyone know where I can get detailed specs on all the Maxximum series motors? I found on their website specs on voltage, rpms, amps and such, but nothing that gives me the dimensions of those motors. Any ideas?

Thanks rhylsadar!

[Rotary Rocket]

I just bought one of these motors from Starluck RC for use in an E-maxx.

I will post my results.

My gear is Hacker Car Comp controller, Strobe slipper, 4S4P 8000mAh Thunder Power LiPo batteries, OTB tranny gears.

The truck has OFNA 7.5 diffs in the front and rear. I will try to run with a 51/15 gear ratio.

The chassis is my own design

That sounds pretty cool RR. Which one did you get, the Maxximum or BigMaxximum? I'm thinking of using a BigMaxximum and a Warrior 9918 for an 8th scale buggy conversion. The Maxximum puts out about 1000 watts and the BigMaxximum 1800 watts. Should have plenty of power w/the BigMaxximum, maybe not enough with the Maxximum? Let me know what you think of the motor.

[Rotary Rocket]

I got the Maxximum. Jaime from Starluck RC said this would be a very good motor for a 1/8th buggy conversion.

The BigMaxximum will want 18 cells, that would be hard to fit into a buggy.

rhylsadar, can you provide the link for the video of your friends 1/8 buggy with the Pletty Maxximum motor in it? Sugs, you will get a kick out of this video.

hi
bigger is not always better. ;) one has to find the "right" motor for the application in mind. as rotary rocket said in a 8th buggy i think a maxximum is the better fit than the bigmaxx. due to higher rpm/v you can get high enough rpms with 12-14cells. and the maxximum has more than enough power for an application in a buggy. of course you can always try to correct with the gearing.
in my view the bigmaxx is really for big and heavy trucks with no problems for positioning large number of batteries and a big controller. one can see that for a first basic consideration out of the data. both motors draw about 70A (peak is higher of course) so one can see to get the 1000watt you may need about 14cells for the 1800watts you may need about 20cells. for using 20cells ore more properly you need a big (read: expensive) controller.
one thing i already mentioned is my reluctance for using the plettenbergs with some controllers. i don't want to spoil the party but i know of some people who really had problems getting those motors run with non-schulze controllers. i don't want to say that it is not possible and as already somebody said in this forum "theoretically" you should be able to run this motors with any controller that can go up enough in khz. but what i saw was that the bigmaxx did not work with a micro 30.150 whatever the reason was...it didn't work. so there might be problem too with the warrior. i also know of several people who smoked their hacker opto controllers with the maxximum. i know of one person who runs the maxximum with a new hacker competition in an e-maxx and it seems to work. of course also some schulze controllers smoked...but mostly with hard setups (long gearing, many cells) and the bigmaxx.
what is clear is that the 4polers burden the controllers harder than the 2poler. so one has to watch the temps of the controllers and use fans on the cooling rips!
here the link for the buggy video. setup is with 12 gp3300er cells, 18.97kw, maxximum. by now there are bigger tires (ofna sst) mounted and 14cells as well. the main problem stays the same: how to get the power on the ground! :D

rhylsadar, is the buggy yours? I always assumed it was, but Rotary just said "your friends buggy", so i'm not sure now..
anywho, more pics and a vid or two of your buggy are also hosted here: http://tinyurl.com/5tcjl

heh, funny how someone decided to ban my domain name from these boards.. d_u_a_l_b_l_.com..

if you get any updates rhylsadar, would you mind sending pics or vids my way? thnx :)

[rhylsadar]

hi nick
the buggy is not mine. i am just the one who pushed my friend to think about BL in a buggy as i made such good experience with my BL savage. he was not sure.... being a nitrofreak for years ..... until we went driving together....after that he was pretty sure that it would be a nice experiment. :D
i'll send you a link if there are news.

rhylsadar,

Do you know what size pinion and center diff he is running in that buggy?

Starluck RC said that 4 pole motors are EASIER on controllers than 2 pole motors!

[rhylsadar]

hi rotary
we first tried 16-18T pinions as we thought we could gear it longer than the nitro. that was a wrong thought. the buggy performed better and the controller stayed much cooler with 12-13T pinion. the spurgear on the centerdiff is that of the landmaxx it is 44T if i remember correctly. so total gearing ist about 11.5:1.
why should the four poler be easier? would be interesting to hear the argument behind that.
as i understand it the controller has to change the "magnetic field" four times +-+- for one rotation of the shaft. with a two poler this is only two times +-. therefore the max rpms on the specs of the controllers for the 4polers are always half the number than for the 2polers.
but i might be wrong....

I had also heard that 4 poles also work the controllers harder..
-Nick

[sugs]

Well now I'm a little confused. A lot of the talk on these boards recently has been that 4 pole setups run cooler than 2 pole setups with the added bonus of less cogging and better driveability. Plus, its being stated that higher voltage is better as well. I want to run lipos so I figured a 5s pack at 6000 to 8000 mah would be a good voltage point (18.5V) to use that wouldnt push the limits of a BK or Shulze 18 cell controller like a 6s pack would. The specs posted on the plettenberg site for the Maxximum show that its limit is 12 cells, while the BigMaxximum is 16-18 cells which is why I settled on the bigger motor. Do you guys think maybe the Maxximum with fan can be pushed harder than its 12 cell suggested limit?

[rhylsadar]

hi
the "coolness" of the 4polers is meant for themselves! :D that does not mean that they are sooo nice to the controllers.
in my savage (18.97, final gear ratio 23-24:1, 13pounds) i drive the maxximum up to 16cells. i have some thermal shut downs with that setup despite the fan on the controller. the problem is the controller not the motor thats why they say 12 cells is max. due to phonecalls some guys did it the plettenbergpeople said 14cells are also ok.
i think a 5s pack will be very hard at the limit for a 18.97 with a pletti (maxximum or bigmaxximum).
you run that in an emaxx?

It's not that simple when it comes to the controller. The 4-pole motor does work the controller harder by switching the Fets on and off twice as much. At the same time, the controller also gets twice as much information back from the motor and is less likely to lose sync. Some of the boat racers swear they smoke more controllers on 2-pole motors than 4-pole motors possibly from this phenomenon. Perhaps Andrewg will chime in with his boat racing experience.

[studysession]

I use 6 pole motors in my cars and have no worries with them. Not sure what is better or easier on the controller.

[sugs]

rhylsader : I'm looking at this for 8th scale conversion.
studysession: Who makes 6 pole motors?

Wouldn't the fact that the BigMaxx has a kv of approx 2200rpm and the Maxx a kv of approx 3000rpm come into play here? Aren't lower kv motors generally easier on controllers, especially when coupled with higher voltage? If I choose to go with a 4s lipo setup (14.8v) the BigMaxx would be turning over 11500 less rpm at full throttle. I'm guessing that would be much easier on the controller. Even at 18.5v the Bigmaxx would still be almost 4000 rpm less. It's a longer can, only 1cm though, would that make that much difference?

[studysession]

As for the # of poles. There are many motors with 6 or more poles. You just don't see them on cars. Cars do not need the torque like planes do. I have been running plane motors for a long time in my cars. Just need to run like 1:1 gear ratios to make up for the lack of RPM's.

The tall gearing does not make the car accelerate slow either. With all the torque you get from a 6 pole motor even though the kv is low - the acceleration with a 1:1 gear ratio is pretty fast and impressive.

Finally got a chance to replace my broken gear in my maxx's tranny, and run the Plette Maxximum. :D

WOW, what a motor. On 4S4P LiPo, 53/15 gearing it would pull up the front wheels at will (in second gear, with a 14 inch wheel base truck). This motor has some serious torque.

I have tried Hacker C50, 7L, and Feigo 8L in this maxx, and in my opinion the Plette has them beat hands down. I wonder how efficient this motor is?

I have a fan on the motor and controller, after 15 minutes of run time (50% in first, and 50% in second gear, out side temp 60 F) the motor was 110, controller 105!

[Rotary Rocket]

I set up my controller per Hacker's instructions (it is Master Comp). At times the truck would brake hard when I would let off the throtle. I am going to reroute the battery wires away from my receiver to see if it helps.

Any help as far as setting for my controller would be appreciated.

Thank you Starluck RC (Jaime) for your advise (and quick delivery) on this motor. :D

[glassdoctor]

Man you got me drooling over this motor. I have always liked the looks of it... it has the fan right? It's 3000kv?

I am still open to what motor to put in my 1/8 buggy. I have a C50, Feigao 8L, and was considering getting a BasicXL/Warrior from Jamie cause everyone has been so impressed by those motors and they are smaller/lighter than a 8L, etc.

I'm working on making my buggy as light as possible.... so the Basic looks good right now. It's @ 3oz. less than a 8L. (215g to 282g I think) The Maxximum is 260g but is that the one with the fan?

I'm interested in how it works for you... runtime, temps etc compared to the Hackers you ran. And how it works with the Hacker esc. I have a Hacker Sport...

[sugs]

Yeah, I'm curious how well it worked with the Hacker controller since it was stated earlier in this thread that pletts work best with schulze controllers.

[Rotary Rocket]

Today's run was very successfull. :D

I flipped my batt packs so the wires would come out in the back, and thus no where near my receiver. IT WORKED. No more "hard braking" when I let go of the throtle. I still can't believe the torque on this motor.

15 minute run (80% in second gear) with outside temp of 58F resulted in motor temp of 113F, controller 96F, and LiPo packs at 104F.

As I mentioned before my truck has an extended wheel base (14.25 inches), UE racer X suspension with 1/2 inch offset wheels, very stable truck. Even with this lenght and width the truck was a handfull with the speeds the Plette produces.

Glassdoctor, yes it does have the fan at the end of the motor (I also have a fan above the motor), it is lighter than the 8L but it is "fatter" due to the cooling fins. Zero problems on today's run with the Hacker controller.

Sugs, my problem in the first run was due to the battery leads being close the receiver. Today the controller was like butter, nice and smooth...

[OptimaMan]

Awesome - which lipo pack do you have?

[Rotary Rocket]

Thunder Power Gen2 lites 8000 mAh 2S4P x 2 Packs.

[rhylsadar]

hi
looks very nice your maxx! :)
i am a bit surprised of only 15min runtime with 8Ah.
rhylsadar

[Rotary Rocket]

rhylsadar,
My run was only 15 minutes (roughly), but the batteries have more capacity. In fact these were the same packs I used in my first test run, so over all they had 25-30 minutes of run time on them with the Plette motor. I also used them in my 1/8 on-road for 5 minutes to test out the new Hacker 12S (it replaced the Lehner 4200).

These TP packs seem to yeild longer run times when you do multiple runs with rest time in between rather than one long run.
