Novak HV-4.5 issue

what are you running for batteries? Did the esc get replaced?

GP3300 Nimh's, IB4200's................not sure why everyone is so concerned about the battery brand/type. They work fine in my EMaxx with a 4.5. So I'm wondering whay that matters so much except that it will allow everyone to pitch their opinion's on different batteries?????

Novak sent me a brand new motor and ESC.

Emaxx? How hot is it when it slows down? What kind of batteries are they? I have 4 8000mah lipo's and 70/14 gearing in mine and it runs for at least 20min without issue.

No, its in a Revo - so same gearing setup. A couple facts that people seem to be missing is that the batteries still have lots of voltage left, AND everything is stone cold. I'm almost wondering if there is some sort of low voltage cutoff malfunction going on in the ESC. I'm going to double check my wires this morning and make certain I wired the battery leads correctly.

I checked all the wiring, and it looks good. I measured the voltage level(s) at the ESC, and those numbers match what I measure at the batteries.

I was going to pull the 4.5 out of my EMaxx and put it in the Revo, but I noticed it has the bent rotor shaft. Guess I'll have to order one of the upgrades now....

I am really starting to get frustrated with this electrical stuff. 3 years of "running" brushless, and I have only had about 4 days of actual operating vehicles (all due to the brushless motors/ESC/wiring). BTW, I didnt have any better luck with nitro, so maybe its the RC stuff period. I can diagnose and fix mechanical failure, but this electron flow has me baffled........

I think tomorrow I'll stop and buy a couple titans and throw those back into one of my trucks. At least they are more reliable......

Might just throw the whole lot up for sale and buy a Croquet Set.....

If nothing is hot I would say your esc is bad. Cheep or old batteries drop the voltage under load allot. Then when you stop and check the voltage with no load the voltage seems fine. If they work in your emaxx and not the revo they are probably not the issue. Just a long shot have you tried to run the problem truck with a different radio? My brother went thru two warranty 4.5 setups before he gave up and gave it to me. Now its in my emaxx it is working fine. His second one lasted less than 10min before dying. Novak has always been a good company but the 4.5 is too much motor for the esc in my opinion.

I may just try the radio. I know there have been issues between the Spektrum and Novak systems. Its worth a shot.
