New from Novak (http://www.teamnovak.com/):

Novak has started this season race ready with the introduction of the new, heavy-duty HV High-Voltage Brushless Motors with 5mm Shafts. These 550-size sensored brushless motors are available in four motor winds—4.5, 5.5, 6.5 and 7.5—and include a Sintered rotor with a rugged, 5mm output shaft. Novak has improved its high-voltage brushless ESC, now called the HV Pro Brushless ESC, and has equipped it with additional throttle profiles and full programmability. The new HV Pro ESC is available in two new brushless systems with an updated HV4.5 (#3024) and HV6.5 (#3026) brushless motor.

Novak had bright ideas for its HV Brushless Motor Series when the motors were released in 2006, and the series has continued to grow to include two more motor winds and a handful of exciting features.

HV MOTOR WINDS

Novak's HV Brushless Motors with 5mm Shafts are available in four motor winds:

HV4.5 High-Voltage Brushless Motor with 5mm Shaft is best used for short, high-speed runs (#3524).

HV5.5 High-Voltage Brushless Motor with 5mm Shaft has superb control, and excels in racing and bashing applications (#3525).

HV6.5 High-Voltage Brushless Motor with 5mm Shaft is the best all-around-motor with a great balance between power and run time. It also shines in racing and bashing applications (#3526).

HV7.5 High-Voltage Brushless Motor with 5mm Shaft has incredibly smooth power delivery, making it the easiest to drive, and is recommended for users looking for the longest possible run times (#3527).

HV BRUSHLESS MOTORS WITH 5MM SHAFTS

In addition to its already impressive features, including awesome starting torque, low-speed driveability, and no cogging for smooth acceleration and smooth coasting, the HV Series has been fitted with a rugged 5mm output shaft for maximum resilience and race life. The HV Series is ideal for monster trucks, converted electric 1/8-scale vehicles and vehicles requiring massive power output. Additionally, the motors are sensor-based, so they always know the position of the rotor, which provides excellent starting torque and continuous synchronization for smooth, controlled low-speed driveability and consistent brakes. Simply stated, it means no uncontrolled bursts of power or delays! HV-Series of motors also features a shielded sensor cable with sheathed sensor wires and a completely rebuildable design.

Nice...

[ElectricThunder]

Meh. Needs a bigger rotor and lower kvs dang it!:huh:

[JohnnyShore]

So where's the cheapest place to find 5mm 32 pitch pinion gears? A lot of what I find in 5mm is in the Mod 1 pitch, which won't work for trucks like an E-Maxx.

[4wdmt]

johnny. check rc-monster and kershaw design. They have the 32 pitch 5mm bore pinions.

[metalry101]

Novak has 5mm 32 pitch pinions coming out as well. Why the Mod 1's are mentioned but the 32 pitch ones aren't is beyond me, but they'll both be available soon. Robinson also has a line of 5mm 32 pitch pinions coming out I believe. I'll have to double check this stuff at work tomorrow, but I swear I've seen both as available for pre-order from GP.

[4wdmt]

That will be great metalry. Buying 32 pitch is kinda hard to find. It will be nice if both Novak and Robinson will release their own. Please verify, thanks.

[4wdmt]

Just got my new HV-Maxx from Towers this morning and this is how it looks like. Same ol' box, just with added stickers, li-po cut off and instruction sheet and of course, the 5mm shaft upgrade:

Novak has to take the HV sign out of them. They are not HV at all. The only HV sensored controllers and motors were made by Aveox. If Novak wants to call something HV, they should at least have a 6-12S lipo controller and a 4 or 6 pole sensored motor to go with it.

Yeah, and HPI should rename the Micro RS4 because its really not that small after all.

Its their product and they can name it whatever the hell they want.

[chewie]

WOAH calm down there tiger... who crapped in your breakfast this morning ?

and the micro rs4 is preety small compared to the super rs4

[Mini-TBasher55]

Yeah, and a Novak 4.5 is pretty powerful in comparison to a brushed 380 motor.

[birdy233]

HV means high voltage, which compared to a regular esc, it can indeed handle "high voltage"

[porra]

I have the following from Aveox: L160, M160 and H160. Now The L version handles up to 16 cells NiXX, the M handles up to 21 cells NiXX and the H handles up to 32 cells NiXX. Funny thing is that Aveox had them back in the 90's. Castle is doing the right thing and will probably introduce a 8S or 12S Monster controller. So what do you guys consider HV. I'm looking at getting a 20S lipo controller for a 5th scale. I have also spoken with another company that will be releasing a 20S controller as well. High voltage, low AMPs is a plus for longer run times and cooler system. Novak has to step up and come out with something that will at least match the Monster Max.

Supposedly Novak has a 6s capable ESC in the works.

If Novak takes half as long as Castle did for the MMM, we'll see a new Novak system in 6 months to a year.

[porra]

Well, they need to hurry up and make it. I new sensored controller to compete with the MMM would be good. A more powerful motor should also be good. In 1/8 scale, they should go with a design similar to Neu or Mega. If any one here has ever seen a Aveox 4 pole motor working with the Aveox controller, you will know what I mean. If only there was a 6 pole sensored motor to work with my Aveox controller.

[SS Pede]

Personally I cannot see myself needing any more power than a Novak HV on 4s (anecdotal evidence...never driven one myself). But if Novak thinks the market for 6s+ 1/8 scale vehicles is big enough, more power to them.

[ElectricThunder]

The HV on 4s is nothing compared to some of the 6s setups out there now. The whole point of higher voltage is not just more power but better efficiency too, which is ALWAYS a plus IMO.

[SS Pede]

True, I'm a big fan of efficiency. I guess the money required for 6s could be a factor too. Anyways, I have no vehicles big enough for an HV brushless system. Maybe an E-Revo would be cool in the distant future.

[ElectricThunder]

Well, if you have better efficiency, you can get away with smaller capacity pack, so you may end up spending roughly the same on batteries depending on how demanding the system is setup to be.

I, too, would like an E-Revo, but it's going to be so friggin' expensive (and not a kit... I'm starting to want a kit now, or at least a roller- I don't need any more crappy AM gear!!!). I need to get rid of a lot of stuff first (I STILL have a p-94 12x2 and a Speed Gems 13x3), then get a summer job, then try not to let my girlfriend know how much my "toy" costs...:D Who knows though, if I do the first few things, I may just get a Belt CP heli instead (yeah, more money into another area of RC...d'oh!).

[desfjr1300]

You'd still want the same capacity, but you can get away with a lower discharge rate. I see Porra's point but have you guys priced 6s lipo's lately? 5000mah Thunder/Flight power $300, $250 on sale. 3300mah's goes for around $220 assuming major name brand. A paltry 2100mah TP/FP pack is $75. Pricey, yes? Like Electric Thunder I got into heli's (that's why you don't see me around here much anymore) and the flight times you get from a 5000mah pack in a 50 sized electric would make you guys puke. Onroad would of course be a different story but there's still crash damage to consider.....One little puncture and that brand new $300 lipo is toast!

[andystoybox]

Helicopter = 1 million peices, each one trying to get away from the one next to it.

and you're worried about on-road carnage? JK

You can keep the same capacity and go for a lesser C rating with higher voltage, or you can go with a lower capacity pack of a higher C rating. Yes, 6s packs are expensive, but most good lipos are expensive to begin with (trakpower has some very nice packs, but they're also about 120 bucks for a 2s). If you race, you're probably going to want good cells anyways. 4s is nice, but 6s is better. Many companies are starting to get into the lipo game now (including intellect!). If 6s becomes a "norm" in racing, then hopefully prices will come down a little bit. It sort of happened with the brushless systems (not a super dramatic price drop, but one none the less). I understand where you're coming from though.

I've heard of the "awesome" runtimes the larger helis get. The CP guys get like, 8 minutes for a 400 size heli (which isn't super huge) on 3s 2000mah packs if they're lucky. Something crazy like that. Probably has something to do with the overall higher average current being drawn in a heli.:eek: Hopefully I'll progress fast enough to invest in a CP machine by the end of the summer (doubt it though).

[Cain]

To me at least, even the lowest KV rated motor there still seems high for 4S usage. I know for the Neu's the 2D is still considered a bit on the nuts side on 4S, and that is 2700Kv.

:D That cracks me up. I've never heard it put quite that way before.......but you're right!

ElectricT, consider getting a sim, and check out Radd's school of flight. (I don't have a link but you can google it up-the guy's a bit of a nut job but if you can get past his eccentricities his methods work) The sim will save you big $$$$$.
Sorry for the hijack, gents.:o

[ElectricThunder]

Did both desfjr1300.:D I actually can hover my heli for a few seconds before the wind kicks up too much and have to land it again before hit takes out my screen porch (only flying a Honey Bee fixed pitch, and it tends to be windy during the day around here). Only took me about two days to figure out how to hover too. I need to find an indoor gym or something of the like to practice more though...:rolleyes:

::hands thread back:::D

[andystoybox]

I know this is completely off the topic of Novak HV stuff but as far as the heli goes, the best thing you can do is buy something big enough that you can fly outside. I tried a Voyager E a couple years ago and practiced in a parking garage ::read-8 foot ceilings:: and never could feel all that comfortable even with simple hovering. I replaced it with a Raptor 30 the next summer and by being forced to fly in a field, I was able to hover almost immediately. Take it outside and you will experience way fewer drafts and currents and the wind will become manageable (unless it's really gusty).

[ElectricThunder]

I do fly outside. I found a good spot out behind my fence in fact (drainage ditch that only fills up towards hurricane season).

It's kind of below these two "hills", one on either side. So the wind isn't really that bad and it's got tons of space. I also tend to fly at dusk when the wind dies down a little. I figure if I can fly this FP outside well, a larger 400 size heli shouldn't be a problem.:D
