Novak HV 4.5 any good?
 

Hey guys,
Got offered a pretty sweet deal on a Novak HV 4.5 system, any opinions/insights into the quality and power of these units or are they just poop? :intello:

Cheers
Simon

opinions.
 

Most of what I have read has been good. There are always going to be haters no matter what the item is:na:. I have one coming in from Tower Hobby and I paid about $230 for the complete system. I won't know for myself how good or bad it is until I get it installed and run it, but almost anything is better than the stock setup:yes:. So if you can get a better deal and it is good equipment go for it. Then we will both be on here sharing info on how the system works for us. Good luck with that deal.:lol:

It can be great or the poop that you describe. It depends on what you're putting it in.

Will be going in a converted Savage running on 12-14 cell nimh.

Well, its fast- 43mph is the fastest its been clocked at so far with GPS (traxxas forum, with photo evidence). But, it does run hotter than the 6.5motor, and does tend to thermal in anything much heavier than a stock Emaxx (9lbs). If the converted savage is much heavier than that I would say its not the best option, since the need to gear down alot will kill your top end rather baddly- 30:1 reduction ratio for 14 cell operation....

I have one in my E-savage.....

And it is fast but you do need to gear down lots (as Neil said) to keep the motor cool.....

Its not a good motor for BIG trucks thats for sure......I would not put it in anything larger than my little E-savage....

In a BIG truck at 14cells (max input) you would kill one pretty quick i would say...

Just my 0.2 cents worth...

For the savage i would go for the 6.5 if you want to stick a novak into it.

You might be better off waiting untill they released their 5mm upgraded motors.

Thanks large for the help guys, a friend of mine works for the Novak importer over here so I can get a pretty good deal. Any idea when that 5mm upgrade is coming out Serum? I already have 5mm mod1 pinions would be nice to stick with em :yes:

If I went for another setup what ESC/Motor combo would you guys recommend for a Savage with 12-14cell nimh?

Personal experiences can vary...

But I put a 4.5 in this truck to test out the electric conversion and have yet to remove it as its running quite well on a pair of 2s2p Hyperion LCX packs. This is an old picture but you get the idea:

I keep waiting for the motor or the ESC to give me problems so I have an excuse to upgrade but so far...zero thermals and not a single other problem - and I would say this truck is heavy, certainly heavier than an e-savage and probably heavier than a converted savage. Gearing is middle of the road, not conservatively low, not aggressive on the top end.

Thanks Steve, do you use a UBEC with the novak ESC? Sweet truck btw :intello:

Nope, 4s is within spec.

So I shouldn't need to use a UBEC with 12-14 cell nimh either?

Nope...the BEC will work fine at the ESC's max input (14 cells)...

Awesome thanks guys, much appreciated :intello:

Jindabyne? Not far from Public Service town :party:

No.....Not far at all...

A bit of topic but do you drive at the Narabundah track?
