Mugen MBX5R .
 

Hello.

What you guys think about Mugen MBX5R ? Is it good car for brushless conversion ? I am maybe putting Feigao XL motor and MMM to that car if I get it. I am not sure about the batteries yet, Zippy-H or polyquest is maybe my choise.

Thanks !

E-Revolution.

I just converted one. I LOVE it. it handles amazing, I have a neu 1515 1y and mmm in it on 4s and it is an absolute beast.

here is my conversion:

Avoid feigaos, not best choise.
Take look on 60mm Medusa MR036-60-2200 if you race, Power will be exact what you need. Not too powerful...
on 4S faster than nitro on 5S beast.
Medusa takes preorders to 70 and 80mm cans MR036-70-2200. They will have more torque and on race you need to be careful with your trigger finger. Super for bashing. Longer cans will heat less too.

Zippy-H deliver very good power for your application. I am realy satisfied with Zippy-H,
Polyquest are top notch. You cant go wrong with polyquest. Only bad thing that they are realy long, not allways possible fit to the chassis

I also have a mbx-5 and love it, here's mine...

Nice ! Is it strong car, no fixing all the time ? I can get one with cheap price. I don't know that what kind of batteries I am buying. Maybe 2 batteries first, this battery: http://www.hobbycity.com/hobbycity/s..._3S_25C_Lipoly what you guys think about those batteries ? They are not cheapest but I think that they worth it. The continous discharge should be bigger but I think that its good with motor like Medusa.

A buggy is amazing for converting; Dafni has an MBX5, and i had an MBX4; Dafni was using his Mugen intense, and the wear on the Hudi parts is outstanding.

They are very tough, and they handle like a dream.

Mugen's are notoriously strong. It is a very hard buggy to break. Last week at the track I pulled into the pits when my lvc came on. a guy overshot the last corner and entered the pits at full throttle. he rear ended my stopped buggy doing about 40, nothing on mine broke, he bent a shock shaft. 1/8 scale buggies on a whole are rugged, mugen being towards the top of that list.

Wow, that is amazing !! I didn't know that they are so heavy stuff. But its very good to know that they dont break every time when driving, its very good thing. I might get one cheap Mugen MBX5R from one guy, so I looks like that I will buy that car.

I am looking some motors and batteries first, then I buy other things.

But I am very happy to hear that you guys like Mugen's :smile: .

Thanks !

Mugen maybe one of the toughtest buggy ever, realy good for noobs and good basher too
What you plan to do? Do you want sick fast car or reliable race buggy?

For racing 4S is enough. If you want race with feeling that you have enough power to burn any nitro go 5S. 6S is waist. on 60m 2200KV motor
For battery i recommend no go much over 500g weight.
On your link is 3S bat or you plan to use it in series, if yes too much weight ~700grams
Once more: with polyQuest you cant go wrong. Every PQ bat from 4000mah feed your buggy easily. Avarage amperage what buggy takes is about 20A only with peaks to 120-130A.
If you go budget Zippy-H will do job fine too, you dont see perfomance in real life. Only maybe in numbers on datalogger.
So continious 100+ Amps is enough

I am maybe interested to buy 5S LiPos, because I were planning 6S batteries to hongnor X1CRT Pro truggy, and it was almost too much.

So 4S or 5S would be good, and Polyquest have good batteries I see.

If I don't find good Polyquest batteries, I will maybe take Zippy-H, thats my plan.

Medusa 60mm or 70mm sounds good to that car. If I have enough money for motor, Neu would be best choise, 1515 1Y .

In my opinion NEU 1515 and Meusa 70mm long overkill. I race only and handling is top priority. Too much power hard to handle and same with weight.
For buggy 1512 and 60mm medusa best bet
For truggy 1515 and 70mm medusa
But this is only my opinion.
If you plan 5S 60mm medusa its more than you can handle.
with 5S 4350mah bat geared 40+ probably you get 15+ min of run time, depends how fast you gear it.

What are you thinking about that battery: http://www.rc-monster.com/proddetail...P-EVO25-50005S ? Flightpower is very good choise too and price is not too high, weight of that battery is not too much I think. Other choise would be this: http://www.hobbycity.com/hobbycity/s...C_-_50C_Lipoly .

So, which one do you guys agree ? Thanks !

Either of those batteries are a good choice. They will perform comparably. I would go for the flight powers just to support Mike! but other than that reason you can not go wrong either way. Make sure you get an appropriate kv motor for 5s lipo.

What kv would be good with 5S ? I think that something like 1500-1900Kv . What pinion is right to Neu 1512 and Medusa 60m ? 5mm pinion ? Both of them looks good.

On 5S 2000-2200 is OK

1900-2200 I would use for 5s. 2200 gets a bit over powered. I ran my 1515 1y (2200 kv nue) on 5s for a bit and found it over powered. 4s seems just right. but that was me, other may love that over powered feeling.

a 60mm medusa 2000 kv or neu 1512 in same range would be ideal motors for the buggy.

For 5s ~1700kv would be about right.

Looks like that Flight Power EVO25 5S battery and Neu 1512 2.5d are something what I am looking for. 4S batteries would be maybe better choise with Neu, or is that 5S too much with Neu ? I want to run with good ( enough ) handling, I don't think that I want overpowered car.

Maybe 4S with Neu ? Or 5S with medusa 60m ? There is alot of choises with batteries, I don't know anything about the Medusa, but I think that its good motor too like Neu.

As I understood NEU's and Medusas most efficent around 40000rpm
Mostly 40mph enough for race.
so 2200@18,5v=40700RPM
Use calculators to find out whitch motor sutes better

Do homework!

Not too grumpy Tom..

Serum absolutly no hard feelings, sorry if my expressions sounds aggresive. I dont speak English very well.
He just repeat same question and i believe that he need to figure out how all things work. Check sticky threads and so on. Better to understand that you do than do all that everyone tells. And ofcorse something comes through experince. But we all allready gave some info to start, no rocket science here.

I run my motors closer to 30k rpms - I like the 2200Kv on 4s and around 1700Kv on 5s - plenty of power, yet drivable and good runtimes. The 2200Kv on 5s is tricky on a loose track - impressive as hell...but tricky to be precise. :)

Well I know those calculations and I have done it with almost all my cars. Well this is not my first brushless project, this is my third brushless project with big LiPo packs. I have done one Traxxas E-Revo project and Ofna Jammin CRT Pro project conversations with brushless motors, brushless controllers and LiPos. Im just thinking about that what would be best setup for mugen. Thanks very much for helping me ! I will look some batteries and motors, and I will buy them soon if I find everything what I need.

Well I like specs like you Mike :) . Plenty of power but handling is still important thing.
I did not found Medusa on stock from rc-monster lists, all 70m motors are gone (?) or out of a stock, and 60m motors are almost out of a stock or there is wrong motors for me :D .
But I try to find Medusa motors. 5S with something like 1700Kv would be awesome. I think that there is no matter that do I take Neu or Medusa, they both looks very good quality motors.

Neu 1512 or Medusa 60mm would be ideal, 1515 or 70mm for a torque monster. I have driven buggys with both size motors, with the smaller motor they are lighter and a bit more nimble, with the heavier motor they push a little in cornering, but pulling the wheels to lock and using power to compensate fixes that. that suits my driving style best.

Actualy NEUs are better, and take look on Tekno NEU motors they are closed, less chance to suck dirt inside motor. With original NEU's you need cover holes, same with medusa.
70mm medusas not out yet they should release it in middle of december. 60mm 2200kv medusas come to stock within 2 weeks or so. Take look on medusa homepage too.

Mike agrees with meeeee!!!!! :lol:

This is my plan now:


http://www.impaktrc.com/product_info...oducts_id=3583

http://www.rc-monster.com/proddetail...=PQXP5s500025c

http://www.rc-monster.com/proddetail...=5mmmod1pinion

Those parts I have planned to put Mugen. Good parts ? Yeah, I know that those parts make such alot of power but I love it :D .

If those parts make too much speed and handling is not good, I can offcourse take 4S LiPo maybe. I don't drive so much now so I will buy one batteries first, later more batteries if possible.

Plan B batteries:

http://www.rc-monster.com/proddetail...=PQXP4s500025c



I will get MMM today.

- E-Revolution.

That is going to be a beast with the 1515 1y on 5s! It will be great for huge open areas and impressive bashing, it will be a bit unruly to turn consistent lap times. It will be fast and fun for certain!

Yeah. Thats what I am looking for:yes: . I think that I won't have problem with power and torgue I think :P . I will order those parts soon when I habe been choose everything.

What pinion size are you considering? I run a 15t on 4s in my Mugen. I would go 12t or 13t on 5s. I ran that same motor on 5s in my revo and found it so overpowered for anything other than speed runs I dropped to 4s.

Well, I am thinking about that I would take 12-15t pinion. IS that a true 5S LiPo pack is too overpowered to drive anything else than speed running ? 4S is maybe better choise because I want to drive something else than speed run all the time :D . Good handling is the main thing, speed can be offcourse good with 4S LiPo batteries too. That 4S looks like good quality and price battery: http://www.rc-monster.com/proddetail...=PQXP4s600025c . Anyone agree :wink: ?

I run 15 and 17 pinions on 4s, that is geared 40 and 45 and find the power just right. It is on the overpowered side for the track, but that suits my driving style. 5s on a 1515 1y is really just silly power, unless you have a pin point precise throttle finger you may find it too much power for other driving than speed runs.

Its a money and power waisting if only possibilities to run are speed running and silly bashing. When I had Traxxas E-Revo, I used BK wanderer XL and 4S motor and I can say that it were going very good with those batteries, Maxamps 10.000mAh 4S LiPos.

How about this motor: http://cbracingshop.com/catalog/prod...roducts_id=123 ? Looks nasty and enough turns/volt. The neu 1515 1Y is maybe better choise, but I am just asking about that motor.

Well now I have been tried to use Ofna Jammin Super Torsen differential in my Mugen MBX5-R , and I have an problem. It won't fit good !! It won't fit normal kind of center differential basement well, because the differential is too big... I had to use "violation" to fix it, but I don't think that its working right.

and there is another problem too.

http://www.aijaa.com/img/t/00198/3257600.t.jpg

How can I fix those broblems or do I need to change my car to another one :D ? This car was CHEAP but its very clean and good to any project. This is why I needed to do my thread to general questions... :D .
