Hpi Pro 4 Bl
 

I just won a slightly upgraded pro 4 and i wanna run a bl sys. that will give both run time yet be pretty fast on 6 cells....I was thinking for the novak 4.5 but i know i could get a faster system then that so i was just wondering what's your opions on that....this car will be used for drift,track, and fun....so i don't want just pure speed!

A 380 6 turn would be close and maybe faster than the 4.5 and with the right esc, cheaper than the 4.5. I'm not sure what esc to run so i'll let somebody else tell you that.

how did you win it?

I think he means off ebay ;)

yeah i won it from an ebay auction for $200 shipped and it's upgraded to match the team driver edition and includes a bmw body.......so a 380 6x will out run i dunno maybe i'll just get the 4.5 with good gearing and team orion li-po i should get some good speeds

i think i would go for the 380 with a nice warrior 7020 or maybe a mtronics pro.

The 6s fegaio 380 is about 6500kv and not sure about novak, but estimates are close to 7500kv. I would still go with the 6s 380 because it has more torque and you could gear up to match the 4.5 and have torque to spare. If you ever went lipo I've heard of people using 3s on it

The Novak will only cause you trouble, to be honest with you. A 6s with 9920 controller and a Team Orion lipo pack will surely make your touring sedan FLYYYYY. If you dont mind about paying some real money, I would recommend the 1920/4 motor with 9920 and Team Orion lipo pack. That motor will easily outrun the novak and the 6s, though I think it wont accelerate as fast the other two will.

The 4.5 is faster than the 6s on 6 cells. The 5.5 was barely slower than the 380c 6s.

Yeah, but the Novaks in many times sufferred from some real damages like the bearings popping out of their place and the magnets getting destroyed and that and that and that....not to mention that it sufferred from all of these problems with traditional sub-c cells and the GTBs do fry alot, too and what do you think will happen to the motor and the controller when lipos are used?!! I dont want to even say it. There are a wide selection of sensored and sensorless motors to go for beside the Novaks. The Reedy Neo One and the LRP are a very good setup with German quality and top performance. I still recommend the 1920/4 motor with the 9920 esc for high speeds and jaw dropping performance.

I agree with the Captain about the 1920,mine runs spookily silent,very smooth and cool,it'd be the most efficient i'd guess,longest runtimes.I'd suggest the 5 turn (46k rpm on 7.4v) or the 6 turn for longer runtimes and cooler temps.

I *HAD* the 1920 5 turn and guess what? It thermals the controllers all the time. Yes, it is an insanely powerful motor, but with JUST 6 cells, they are all the same. The 1920 5 turn is actually slower so I have to use a larger pinion gear to achieve the same speeds. Now, if you put 12 cells on the 1920 5 turn, it is WAY MORE POWERFUL than the Novaks, but I don't recommend 12 cells on the 1920 5 turn (yes, I know, I'm way past the RPM limits).

I also had the Hacker C40 6s, the Feigao 380C 6s. Honestly, my favorite is the 1520 10 turn with 3s lipo for the touring cars - but the motor and adapter plate will set you back the same amount as the GTB 4.5. I also like the Basic 5300 on 3s lipo in my TC - very/too powerful. :)

BUT, with the limitations of 6 cell and or 2s lipo, the GTB 4.5 is the fastest except for the very hot wind 1515 and 1520 series.

BTW, I've tested the GTB 5.5 and it'll pull 100+ amps all the time during peak output. It also seems to be about 6500 KV which should put the 4.5 around 8000 KV!!!!!

AND, I'VE NEVER HAD PROBLEMS WITH MY GTB or SS5800.

It always depends on the user, lipomax, and I still think it would be possible to take down the 4.5 with the 1920/4 and not the 1920/5- who would want to use 12 cells, anyway- a good controller, high capacity lipo packs( like 6000-8000mah) and a gear ratio that would make your car go over 45mph easily at 8.4V. However, I cant argue alot since you'd used the thing. You said that you'd used the 12.97 esc with the 1920/5 and it thermalled. I think that problem would have been evaded with the Warrior 20120 controller or the MGM 12012.

It all depends on how much would you pay to go fast. I might go for a reedy neo one, but not a Novak.

I can't really comment on the low turn 1920s on low cell counts,mine is a 10 turn on higher voltage so i just figured that the 5 turn would work well with 6 cells but apparently not.I use mine with a 18.97 on 3s most of the time and i can 't really get any heat out of the motor or controller.

Thunderbruiser,it depends what you're looking for,i don't think a system that's faster than the 4.5 on 6 cells but also does runtime and not just pure speed really exists,two different things really on only 6 cells.If runtime is what you want then maybe a slower turning motor like a basic5300 or a 1920/6.Some more voltage would achieve both easily though.

yeah i don't want it to be just a speed car so most it'll see is either 6 cells or 2s lipo...which of course would be run in the future.....I think that i'll just get the 4.5 because i want this car to be normal in a sense and i think that 12 cells in a touring car is overkill seeing as i plan on running around a course...thanks a lot for your imput fellas!

The Lehner Basic 5300 with the MGM (120 amp) controller is a great combo for a BL TC running a six cell pack or a 7.4v LiPo. The MGM 90 amp controller would be fine if you are only going to run up to the 7.4v LiPo.
Sometimes, just for speed runs, I will switch to a 9 cell GP2200 pack (which fits perfectly in the space for a 6 cell GP3300 pack).
It may cost a more than the Novak, but it works great.
Matt

money isn't really an issue i just want a good setup that will perform well on a 6 cell pack and not be too ballistic to handle lol

Then, the 4.5 might be too much for you.

really i thought it'd be kinda slow of sorts lol i have driven some fast rides...I mean i want speed but i want to be able to drive normal

Hmmmm..it makes sense. Well, have a nice ride.

i guess the 4.5 will be my best buy and i'll run a fan on the motor for even more cooling....and go from there...thanks for you help fellas i'll post pics once i get the car and install the sys. and what not

The 4.5 isn't that fast, on a magazine test in a touring car, it only toped out at like 42mph.

ygguB naM....... I think I've spoken to you in the Team Associated B4 forum 2-3 years ago. You were the one who recommended me to use a 6 turn V2 motor to make my B4 go 50mph. Wow, that was sometime ago. Well I was able to push it beyond 50mph with a 480 brushless motor at 12volts. It was an exciting ride for sure.

yeah my friend was saying it wasn't that fast...well i just purchased two 2sp 8000mah li poly's from max amps so that opens some doors up i guess cause i know they have way more out put than what i normally use.....so what about that 380c 6 that everyone was talking about?

would a quark 80 amp controller be able to handle a 3s 8000 mah pack and say a lehner 5300?

How fast did it go on the 6t?

would a 2 or 3s be good for a 1920 5turn? and do you think it'll be faster than 4.5?

Eeeaaaasilllllyyyyy.

I did not even get it. I directly went to the Kontronik motors by chance.:027:

currently using the sys from my rustler due to my rustler being broke and awaiting some parts

Do not get the 540 6s or the 1920 5t or 6t. They may be faster after 500 feet of straight, but they will feel very under powered compared to the novak 4.5 or the feigao 380 6t.

really i thought the 1920's were fast?

I think a 5300 would be more than fast enough.

I put one in a Tamiya Mini (yes, the FWD one). Even going insanely fast i can get wheelspin.

Geared as high as i can get - on the first pass on the first vid i go from half to full throttle just past the camera - you can hear it keeps accelerating for as far as i have room ;)

I cant imagine what this would be like with the reduced weight of LiPo.

Guess there's only one way to find out...

Currently, judging by how far it moves from frame to frame i estimate about 45mph.

Even this would really get your Pro 4 flying

darn that's plenty fast...but my question is can that handle a 2s or 3s lipo?

Yes, but it's a bit hot for 3S

It will work, but it'll get very toasty. Would be perfect on 2S, however

that liitle car sure does move

hmm....what about the 3100 that would be pretty nice and it says it's designed for higher voltage

That would be excellent on 3S!

It would also be nice and mild on 2S too.

If you are going to be mainly running 3S, go with that.

If you're mainly going to be using 2S, then go with the 4200 (that way you can still do insane speed runs without things getting too hot)

Keep in mind that in the vid i was using six cheap, unmatched GP3300s.

On lipo you would have more current and more voltage - but if you are planning to run a mixture of 2S and 3S then the 4200 (or whatever it is) would be a good choice

There's always the Feigao option - the 6S is a very fast motor indeed - not as much low speed power as the 5300 but it really pulls at higher speeds. Just gear it quite low.

If you bought something like an 8 or 9S you could run both 2 and 3s lipo, save a bit of money and still have nitro-killing performance ;)

well i have a reedy neo 9 turn in here now and it kills on matched 3700's but i was thinking of getting the 1920 but i hear it's only top end i want more than just top end i want all around...i am thinking of getting the 3100 cause i'll mostly run 3s lipo's and they're 8000 mah capicity

I think you've made the right choice :)

You could consider the Basic 4x00 - and gear low so that it runs a bit cooler?

The 5300 is capable of absolutely savage acceleration - i normally use it in my T3 but thats waiting on new diff balls atm...

The 3100 would only accelerate faster, and on 3S you could gear quite high to give you truly insane topend as well
