Basic 4200 vs. 5300

[OptimaMan]

Geez, it seems a lot of people have questions about which of these is the motor to get...

It depends on what you want to do with it. If you plan on actually racing it in the dirt such as 2wd buggy, 2wd st, 4wd buggy, I'd say the 4200 is the motor to get because it's not as powerful and it's more efficient so the controller won't get so hot inside that tight fitting body.

If you want to race touring cars in a wide open carpet high speed track, the 4200 is a bit too slow. A 5300 is definitely better - if you are a decent driver. If you are an expert driver, even the 5300 might be too slow and you might need to go with a Hacker C40 6 turn or others.

If you want to make record speed runs, a 5300 with 10 cells vs. a 4200 on 12 cells will be similar in RPM, but the 4200 will have more torque and be more efficient so the batteries and controller won't get as hot and the speeds won't drop off as fast. Having said that, a 3100 on 18 cells will beat them both.

The point is, there is no one magic motor that works for all applications. The 5300 is like a really torquey 10 turn while a 4200 is like a really torquey 12 turn. The Novak is NOT (in my opinion) like a 10 turn - more like a 12 turn if you ask me. So, if you were running brushed motors, would you run a 10 turn single on a 2wd buggy on a dirt track? Probably not. BTW, a C40 6 is like a high torque 7-8 turn single.

Hey O-Man, thanks for educating me on the motors.
I just bought a Basic 4200 for my 2wd buggy, sounds like I picked out the right one.
Our track is tight & technical. Actually where redoing right now for the fourth time in a year, it's huge! Have a Bobcat for 4 days, that's a beautiful thing!!! :)

Thanks for the the little motor faq optimaman!! Helped me out a bit and I still plan on getting the 5300 because it will hopefully be powering a converted GT which will way more then a T3 or T4. Good to see a lot more people posting in the bl forum again :cool:

Man I REALLY like this new forum setup, a lot nicer, easier to get around (imo), and it looks good!

i just got the 5300bl to run in the xxx4 buggie....it is much to powerful for short technical loose dirt tracks ..so i used the 6 setting and bam works like a charm ..so i belive the fexability of the 5300 is better and more versital

[glassdoctor]

We also can't forget the ability to gear down and control our throttle fingers. I want to try a 5300 and see how much faster it is than my Novak. Or try a C40, but it's even more $$$

GOOD INFO......
Got a question though, if a,
Basic 4200 = 12 turn brushed motor, with more Torque
Basic 5300 = 10 turn burshed motor, with more Torque
C40 6T = 7-8 turn brushed motor, with more Torque

Does the Lehner Basic Series have more "Torque" then the Hacker C40 Series, on a low cell count (6-7cells)?

[DualBL]

Swami had a c40 (forget which turn), and he couln't wheelie his rustler, w/ similar gearing/cells, as peopl's setup w/ 4200's or even 5300's.
I've never run c40's, but from what I've heard, a lehner basic has more torque.
but then once you go to C40 20t's, they'll have more torque, but rpm for rpm, lehner has more torque
btw, i don't know if they make a c40 20t, but you get the idea.

I believe swami could wheelie with his hacker, he had old batteries at first, but i think he could def. wheelie his rusty with that motor on 6cells, he has the hacker c40 8s, he later got a 5300 and commented that it was much more powerful on the same cell counts as his hacker.

After watching his video i can definately say swami had no problem lifting up the front with 6cells.

[mollycbr123]

I run 1/5 motorcycles. I've had Novak 5800's in two bikes for a year or so. Just installed a Hacker c40 8t and a Schulze 18.61 ESC in a third. The H/S setup definitely blows away the Novaks. No comparison as far as speed, torque, and power. The Hacker/Schulze takes the bike's performance to a whole new level. My biggest problem with the Hacker bike is keeping the front wheel on the ground, but who's complaining?

Just passing it along...

Without a doubt, the Lehner Basic has more torque rpm vs. rpm. But then again, it's got a larger diameter rotor. The c40 is a 400 series rotor diameter while the basic is a 500 series rotor diameter.

Now, for a very light vehicle (pan cars, touring cars, possibly 2wd buggies), the c40 has enough torque. One thing to keep in mind is that because the c40 rotors are smaller and lighter, the rotating mass is smaller and can rev up faster to speed and it's more efficient at LOWER amperages. The Basic series are efficient at slightly higher amperages (specifically the 5300 and 4200).

[DualBL]

hmm, maybe it was someone else...
you sure your watching the rustler vids, and not when he had it in his pede?
i remember someone saying that they couldn't lift the wheels w/ ease in their rustler like many can w/ a 5300, and i thought it was swami.

I am no brushless expert, but here is some my take on 5300 versus 4200 question:

1- If you want to use NiMh, then the 5300 would be my personnal choice because it is will give you more rpm (hint more speed) under 7.2 v (7.2x5300 = 39750 rpm) or even 8.4 (44 520 rpm) than any other Lehner motor.

2- If you go the Lipo way, then the 4200 would be better in my opinion:

Given the 65 000 red line of those motor, you want to be as close as possible from it.
In order to do that, you have to raise your number of cell for increasing voltage and rpm.
With a 5300, I think the limit would be 3 cells, because 11.1x5300=748800 rpm and more than likely you'll blow your motor.

With this in mind, here's the Lehner motor max rpm with lipo:
A Lehner 5300 running under 11.1 volt = 58 830 rpm
A Lehner 4200 running under 14.8 volt = 62 160 rpm
A Lehner 3100 running under 18.5 volt = 57 350 rpm

Again, to my opinion, the Lehner 3100 would require way too many cell (hence more weight and space, not to mention price) to be my choice.

The 5300 wouldn't be my choice either because less efficiency, less rpm on lipo than the 4200.

The 4200 would be my choice because it would be easy to have two 7.2 pack hook-up for 14.8 volt, it would be a good setup efficiency wise and it is as close as possible as the 65 000 rpm limit. It should as well not drawn too many amp thus meaning less problem and less heat for the esc.

Anyway, I am following Optimaman ( thanks to him for sharing his brushless knowledge ) footstep and already ordered a Pro4, the 4200 is the one I'm going to get...

I have to agree with OptimaMan and listen to him, he has some good information for you guys.

I have both the 4200 and 5300 with an 18.61K Schulze ESC. The 4200 was used in my 2wd T-4 with the 5300 used with my XXX-4 4wd buggy. The 5300 is alot of motor in the 10th scale 4wd, but was as powerful as the Hacker system I had in with the Hacker Master Comp ESC and the C40 8 turn motor.

I perfer the Schulze ESC over the Hacker ESC due to radio adjustability and smoothness with the brake and throttle.

Good Luck!!!

I have experience with the basic 4200 and it over revs on 12 cells without load. The 4200 rpm rated is under load so it have about 15 - 20% more rev free rpm. Also the rpm is not the main factor for speed. The motor internal resistance and you gear ratio is what makes the difference. Overall the basics all put out the same maximum power which is 700 watts. For the 5300 to put out 700 watts it needs to draw more amps than the 4200 while the 4200 needs more volts. The lower the internal resistance the higher the motor effiency.

[wothrottle]

I´m wondering if it´s possible to use a 5300 and limit the speed(esc or transmitter) to get the most out of a combo-fast on demand!
Or is there a downside to it?
I want a motor for a t4,but sometimes I´ll switcht it in my touring sedan,so the extra speed would be nice.

[DualBL]

if you want it to go slower, you don't use as many cells.

What do you think would be the best motor choice in an E-maxx from Lehner?

Basic 4200?

XL3100?

I will probably be running 8-12 cells, with possibly a U-force 75 ESC.

Runtime, and about a 40mph top end is all I am looking for.

[schenck77]

out of those two motors i would go with the 3100xl. the basic 4200 would be underpowered in an e-maxx.

[Simen123]

On 8-12 cells I would use the Basic4200, or something with similiar rpm.
I recently bought an e-maxx off eBay, and I`ve tried it with a Lehner 1920/10 and the Basic 4200. Both on 12 cells, with a Schulze 12.97fwe.

The 1920/10(it is a 5t, but soldered to be a 10t, which gives it 3135rpm/v) has about the same rpm`s as the XL3100 and it didn`t really wake up on 12cells(pretty new and punchy Orion Team matched 3000HV cells).
Even on some older cells(that I would never use in my touring car because of lack of punch) the Basic 4200 was much quicker overall, and also put less strain on the controller as it hasn`t shut down one single time (it did that some times on the 1920/10).

The 4200 is getting much hotter than the 1920/10 though, so I am buying on of those small fans on eBay for it..
