Is the HV really that dependable? - 02.19.2005, 07:23 PM

I don't know much about it but i'm just thinking out loud here.

If the HV-maxx costs $300, and their marketing device is that the HV is dependable and that it doesn't cogg, the top speed is like 32-36 mph and they recommend that you run 17-72

Now is this really more dependable than a feigao-9918 setup?
Think of it this way, if you setup your feigao-9918 system to go 32 MPH on 17-72 gearing (same performance as HV), your probably looking at a 9918 on a 14L. A 10L pulls 61 amps so a 14L would pull like under 40 amps (just guessing).
Now running a 18 cell controller that is rated for 99 amps on 12-14 cells that would pull 40 amps, you are looking at an extremley dependable setup at the same price, speed, dependability (if not more dependable), more efficient (higher turned motors are more efficient), but with ALOT more torque. I know not everything i said was correct (maybe the 14L should be a 12L etc.) but do you think this idea is accurate?

I have another question. Novak advertises that their motors don't cogg at low speeds. I think what the public fails to notice is that there is a difference between low truck speeds and low motor speeds. So even though the truck itself is going slow, the motor is actually not going slow (because its on 17-72 gearing and it takes more rpms to get the truck moving), so would the motor cogg if you ran it at a normal gear ratio like 18-66?

Any views on this?

The sensored design of the Novak lends itself to smooth low speed operation. No doubt the warrior and Feigao motor would be bulletproof if it was dumbed down to 32 mph. The warrior is a very dependable controller even when pushing the trucks to 40+ mph. I can't speak intelligently on the Novak's efficiency, but a 14 cell setup geared to go in the low 30s (probably a 10L/warrior) would have a pretty good runtime for sure. The torque would be pretty incredible with this setup as well(tough to handle kind of torque with good cells).

why aren't the other BL's sensored? Would it cost too much?

Generally speaking, the sensorless design is capable of higher efficiency, higher rpms, more power and lower cost. The tradeoff is less favorable slow speed driving/rock crawling.

The HV maxx itself is pretty dependable. I have it and have been running it for a couple of days now. The only problem I had was that I thought that the reverese was no longer working but it was my mistake. It also cog free. The novak system is also plug and play.
