Looking for something to power my jato/pede Novak 5.5/6.5 or 5800?

[captain harlock]

Novak is good, but reedy is the master of motor designing since he won 24 ifmar world champion ships and his motors are always a top notch, not to mention that they are made with German level of quality. The 9t Neo is the lowest in turns, as far as I know, but in terms of power, you can compare it to a 8t hacker C40. Also the novaks are 195 watts rated, while the Neo is 250 watts rated. You can use it with seven cells, too.

The Neo One is a 6.5 wind, for comparison to the Novaks, if you absolutely insist on staying sensored and running 7 cells the LRP combo will work fine.

[captain harlock]

Also, Novak is known for bearings popping out of the motor can after some hard usage and their brushless controllers usually heat up alot. People I know who use the Sphere/ Neo setup did not find anything abnormal about them.

[Rtsbasic]

Hmm, I have seen a few burnt out LRP combo's locally - problems with the sensors in the motor are the most common, but then again they are quite a bit more popular around where I live than Novak so I'd expect to see more of them go.

[captain harlock]

It always depends on the user himself. Even the most durable system can be wrecked if it was used harshly. Yes the sensors are usually the problem, too.

The Neo1 Four Star is 5.5 turns and it's supposed to be equal to a 7 turn brushed motor. Also, the reedy and novak motors have the same rotor size as the hacker c40 and feigao 380 motors, so really, they will have the same overall power on 6-7 cells.

were are these pics and vids roost:p

They will hopefully be here shortly! They are all on my buddies laptop, and he had his wisdom teeth pulled so he is kind of out it.

I cant decide what to do right now for a new brushless..

I can keep the ss5800 I have now, which is a decent system, but more power is always nice.

OR, I can do the 9920 combo with an 8s motor for 225

OR I could go the mtroniks controller (which is better, for a pede? the truck or the pro?) with a 380c motor for 230/245

Hmmm I dont know which would be the best setup? Any help here?? I want smooth running with good power and efficiency on 7 cells (ib3800s and gp3300s)

Thanks guys

[Rtsbasic]

The Mtroniks controller will be much better than the 9920 on lower voltages - smoother, easier to control. The Pro or Truck will both work, personally I run a Truck for that extra safety margin but ran my Pro in a 1:10 truck all summer no problem.

The 540 8s would work well with either on 7 cells, a 380C-6L would work well as well. All Novak brushless motors use a 380 size rotor btw. Personally I run a 540 6s when only running 6-7 cells, with the right gearing and good batteries it really comes to life, but a lot of people will recommend against this motor as it needs good batteries to work well, and can be outrun by a 380 sized motor in conditions where torque isn't a factor.

[R00ST]

Thanks, this is good info! (experience with specific motors/controllers is such a great deal more helpful than just hearsay and what manufacturers say!)

I do like torque, but being in a lightweight 1/10 with pretty small tires may not make a huge difference... What is the difference between the 380c 6l and the 6t? I noticed only the 6l is available with the "L" is it a longer can than the t's?

I have 2 new 7 cell ib 3800s SXS packs, and three reasonably old 7 cell stick gp3300s (are a bit flat, probably 35-50 runs on each)

How good does the gearing have to be to run well? I prefer setups that are not finnicky, as I change tire sizes a lot and it would be nice not having to mess around with pinions/spurs trying to find the perfect setup to make the motor happy.

Thanks again for your help! Anyone else who has experience with these setups feel free to chime in as well :)

[Rtsbasic]

The difference between a 380C 6t and a 6L is the L is 10mm longer, so produces extra torque. Somewhere between the potential power output of a 380 and a 540 sized motor I believe. It has the advantage of being able to spool up faster than a 540 but still have a good bit of torque. The shop that stocks it only has the 6L in stock as I guess its the only one in demand at the min.

Your batteries will work well with pretty much any motor you pick for your pede/jato. I have GP's that are older than yours (coming upto 50-60 runs) that work well with my 540 6s which is the most amp demanding motor (and most powerful on low voltages) i have.

The problem with a "one gear fits all" solution is if you gear for say pede sized tyres (5 inch), then put stadium truck tyres on (4 inch), your gonna loose a lot of top end. If you gear for stadium truck tyres then put pede size ones on you may hit have heat problems due to overgearing. Brushless is pretty tolerant to gearing in light cars but a lot of this depends on the motor. I have to re-gear my 540 6s when I change the tyres otherwise I loose out on acceleration quite a bit, because as your no doubt aware there's a sweet spot for any motor. I guess you could go for a happy medium if you really dislike having to mess with the gearing.

[R00ST]

Well I dont mind that much (only takes a couple of minutes tops) I was mostly worried that it would be difficult to find the "sweet spot" in the 540 (or either of the motors for that matter)

I dont think it will really be a huge deal though. I usually prefer to gear down a tad anyway to keep things cool and keep acceleration quicker.

I am still at a loss at which motor to get! I know I will get the mtroniks Truck controller, but 380c 6l or 540 8s

If you were in my situation which would you go with? Would the 8s have less run time seeing as it is a 540 (but it is a slighty higher wind.. hmm)

I do like a good bit of runtime.

[Rtsbasic]

To be absolutely perfectly honest with you there's that many motors around that 30 people could recommend to you the "ideal" motors which are completely different, and they'd all be right.

In theory, the 380C 6L should get more runtime because the smaller rotor, takes less energy to turn, but the side effect of this is a drop in torque compared to a larger rotor. But being a lower wind it may make up for this, and revs slightly higher than the 540 8s. Its all swings and roundabouts, my personal preference is neither of them..my 540 6s (actually I have two, one Feigao branded, one Mtroniks branded) serves me well. But out of the two I would probably go for the 380C-6L.

Its not really that hard to find the sweet spot on gearing..all it takes is a bit of time, what most people I know do is just pick the top speed they want and gear accordingly for that, as long as it doesn't overheat anything it seems to work well as a starting point.

And just to help confuse you with the gearing a bit..to a point, a 540 will accelerate faster with higher gearing, because the time it takes to spool up anyway.

So at the end of the day I'd go for the 380C-6L over the 8s. With my setup (540 6s) I can dump a battery in 3-4 mins if I want to, so I wouldn't recommend it to you, although it may be more powerful than either of the other motors.

[squeeforever]

as for controllers i would go for the pro because i was told that the truck is VERY heavy and bulky and is the same internals. if i am not mistaken the only difference is the aluminum heatsink.

[R00ST]

I guess I dont know why I said 8s...it could be any available 540 motor!

I guess I like the idea of a bigger can, figuring more torque, but then also higher amp draw. But on the flip side..if comparing to a smaller can, to reach a certain level of acceleration it would take more juice from the smaller motor to get the same affect.

So I guess it is any of the 540 motors and any of the 380 motors (but seems the slightly longer 380c 6l is a good option) What about like a 7-8t (380)? I really only want slightly more power than my novak ss 5800 is putting out on 7 cells. I really do enjoy my runtime rather than having a 50mph truck that dumps in 5 minutes.

And squee, thanks for the input. So the truck has the heatsink, making it bulkier? I guess it seems like the more expensive higher rated pro would be the more durable unit? I really dont mind the weight of it (im assuming it cant be too heavy) just as long as neither of them is overly large. I also wouldnt mind saving the 15-20 bucks over the pro if the truck isnt too bad.
