Novak Replacement Option for (original) HV ESC (P/N 3220)
 

When the original HV ESC (P/N 3220) is returned for replacement, it is being replaced with a new, on-board programmable version. This replacement version still includes the 4-cell Smart Stop lipo cut off module as a standard accessory.

This repl version contains all the new programming features offered in our new HV Pro controller (P/N 3221). However, this new Pro controller has new PCBs---Lipo circuitry is now built-in and it's been updated with higher voltage transistors. The original HVs are not being replaced with the new HV Pro speed control.

There have been delays in the transition to this upgraded replacement HV. We wanted to add all of the new programming features and we needed to write all new instructions for the programming options for our service customers.

I want to apologize to any of you who have experienced delays in receiving your HV replacements, If any of you have specific questions, let me know and I will get answers for you.

I have a bad hv esc that needs replacing. Is there any way to send it in without your return form? I have no way of printing anything right now.

Here is the page that includes the link to a PDF version of our NW replacement service form:
Speed Control Options

Just follow the format from the NW form in a letter including all of the required details---especially contact info and CC info. Should not be a problem.

I dont think Novak would warrenty my old original esc, its been through the mill a little :lol:; tough little blighter, served me well.

All original HVs ever shipped can be returned and replaced under our Replacement Options program---just send it in with the Non Warranty service form. The price of the rmf HV itself is $65.

So thats $65 to get a rmf esc basically, if I send my one in? I should post some pics of it before hand, your engineers would have a heart attack if they saw what I've done to it...

If our tech guys had heart attacks looking at such customer returns, we wouldn't have any tech guys left......

Go ahead and PM me a photo before we have you pay to return it.

Im not worried about returning it for a new one in all honesty; its nearly 4 years old, so all Im gonna do is replace the motors leads, re-instate both sets of battery leads with some deans or trx connectors, and give it a bit of a clean to remove the dirty marks. Then it will be sold on feebay since my MMM is a good one which hasnt died within the 1st few minutes or hours of use. Still, thats a good warrenty system you have, and its a good power system for what it is- looking forward to the next gen of escs and motors from novak.

Some beauty shots of my esc, just for curiosity's sake:

Four of the motor mounting holes are stripped.
Esc has dual caps.
Esc is shorted for single pack operation.
Motor leads have 5.5mm bullets.
On/off lead has been replaced- new wires soldered to pcb, and to switch.
Case is also melted by soldering iron in a few spots.

At least you didn't fry yours by trying to beef up the traces and inadvertantly short a few FETs (it was a rainy, boring day, and all my RCs were actually running- what was I supposed to do?!)...:lol:

I probably should send the ESC in for replacement, but I'd want the new HV Pro doo dad, and I don't think I have that kinda money at the moment.:whistle:

Made this this a sticky. Thanks for posting NovakTwo

From my understanding; It is possible to do a $65 trade for a non-defective unit?

HV-maxx PRO. higher voltage transistors? do I hear 5/6S capability?

The replacement option program offers the newly programmable HV esc in exchange for original HV escs returned for service---$65.00 is the price of the rmf controller.

The new HV Pro controller (#3221), shipping out separately and with the newly-released systems, is officially rated for 4s. However, the internal lipo circuit will allow it to be used with 5s lipos, but not 6s. I think that if 6s lipos are hooked up, the esc will not program.

We are still in the prototype stage for the 6s controller---Bob ran the protos for his testing of the new conversion kits.

Any pics of the prototype? A nice feature on your website like for the mongoose system would be good for generating interest :yes:

This is interesting, 5s lipo with the lower kv HV motor (7.5?) sounds like a good system. The lack of internal lvc and programability was keeping me from buying a Novak hv esc. Guess I will have to pick up one.

indeed James.

5S on the 7.5 sounds reasonable to me!

Looks pretty clean to be honest... I think an BNIB would sell for more and worth sending back...

Novaktwo, are you saying I can send my HV-maxx ESCs to be upgraded for $65 each? one of it wasn't running so I opened it up and found the internal cap leaking, so I replaced that and now working alright. Replaced both external caps too. Both running at the same time.

I have had good success with the smaller novak motors, and their SS and GTB escs. Nice to see Novak providing more options in the higer voltage section of their product line.

I have not had much success running my 6.5hv motor with a MM. Even with the newest firmware, it does not like starting the motor from a standstill. It is in a rcm chassis crt.5, with a MM and a Neu 5000mah 25c 3s lipo. Gearing is 15/47 (custom plastic spur). I may be overgeared and undervolted, it does seem that way....

I would like to get some time on the motor with 4s lipo in something.

You can return you old HVs for replacement for the charges listed in the replacement options chart and on the NW service form (both linked above)----whether working or non-working or modified. We send all items returned for replacement to our rmf department, where they are completely dis-assembled, cleaned in our ionic washer, and re-assembled and tested by the same employees and same QA testing equipment as our new items.

I did learn that the replacement HVs do not include a new Smart Stop lipo cut-off module. If a customer returns his lipo module with his esc, we send it back with the upgraded, re-manufactured, programmable HV controller. We also clip off and return any costly connectors (e.g. Deans).

Great news. If you can get a 6s sensored system out before I buy more MMM and Neu's I will definetly buy one. I really like Novak motors in my 10th scale stuff.:rules:

Yesterday was the first day that we began shipping the new 4.5 and 6.5 HV Pro systems out to our distributors in the all-new HV Pro packaging.

The new 5.5 and 7.5 HV Pro systems and the stand alone HV Pro controllers will be shipped starting next week. All these new HV Pro products that started shipping yesterday feature the newly re-designed HV Pro speed control with the built-in Smart Stop circuitry, higher-rated mosfets and fully upgraded programmability:

Three profiles, nine adjustable programming parameters:

Minimum Brake (10 settings from 0-30%)
Drag Brake (10 settings from 0-30%)
Dead Band (5 settings from 2-6%)
Minimum Drive (5 settings from 1-12%)
Throttle Curve (Linear & Expo)
Brake Frequency (7 settings from 1-8 kHz)
Brake Disable,
Motor Rotation
Auto-detect Li-Po Cut-Off

All of the new system features can be seen here, with links to the individual pages for the HV Pro motors and the HV Pro speed controls:

THE HV SYSTEMS REINVENTED AND BETTER THAN EVER

A Peplacement Option re-cap.......
 

All original HV controllers returned for replacement will be exchanged for a remanufactured (orig) HV controller upgraded with most of the new programming options listed above.

The rmf version will still require the external Smart Stop lipo module (a new SS module is not included with the rmf esc for the price of $65.00.) But the rmf controllers will have our new 2s-4s Transcap Module installed.

The soon to-be-shipped HV pro controller (#3221) is a different controller with new PCBs. At this time, we are not offering it (as an upgrade) as part of our replacement options program. We generally add new items to the program 3-4 months after we begin shipping.

Just for clarification, Novaktwo. If you send old esc and 65.00 for non warranty replacement, you get the previous HV without the 4s cut-off? If so, what would it take to return for upgrade hv-pro? If it doesn't have the built in cut-off, its not worth trading in to me. Its a great deal if you need it fixed, to upgrade. How about the motors? i got a 4400hv with a sintered upgrade, how much to send and replace for a 7.5hv w/5mm shaft? Thanks and i await you're answer

I think NovakTwo mentioned that in a few months (3-4 months after release) they will start allowing you to replace your HV-Maxx with an HV-Pro, same situation with the motor I am guessing.

Of course, my reply is not official (I am just a customer) so hopefully NovakTwo will reply and answer your question with more certainty.

cmcclive was correct. It will be several months before we add the new Kv HV motors and the HV Pro controller to our NW remanufacture, Replacement Options program. It takes quite a while to start getting enough new items back for service to then remanufacture them and add to the program.

The original HV-Maxx can be upgraded to the new service replacement version by re-programming the microprocessor, while the new HV Pro is completely redesigned firmware and hardware. So it is a new controller, even though externally it looks the same.

The Novak customer service is pretty awesome.

So if I wait 3-4 months I can send my HV-Maxx in for an upgrade to the new Pro with 2-4s Lipo Cutoff? I can wait....:party:

As awesome as we are...:yes:I have to add that we have not yet set the price of the upgrade to the HV Pro speed control. It will be more than $65.00. It is a different controller, and frankly we could go out of business if we offered to upgrade 4 year old speed controls to a new version for too little $$$!

We do currently allow customers who return GTBs for service to request any one of five different GTB versions in exchange for no upcharge. We like to establish "win/win" exchange service policies whenever possible. With BL motor exchanges, we allow customers to choose any sintered, wind they want in exchange for about 10.00 additional.

For example, when we added the lipo to the GTB, we received a lot of the original GTBs back for exchange. We had very little use for that many orig GTBs for the exchange program, so we offered them, remanufactured, on SAT for 99.00 to 119.00 and they sold like hotcakes. Likewise, too many of some wind reman 540 motors can be offered in the store for a good price.

NovakTwo I sent you a PM could you please replie to it,thank you.

I remember back in like 2002 or so I sent in my novak SS4400 or something like that their first brushless setup. Charlie emails back asking for more information and viola about within a week or week and half I was sent a new one....I have to say novak was incredible customer service I sent in a HV 4400 same deal all within warranty. I Paid one time due to it being out of warranty and same excellent customer service every single time.

i have a hvmaxx 4.5 system (broken) that i want to upgrade to the hvmaxx pro w/ 6.5 and a 5mm shaft, however i am having a hard time filling out the paperwork....:oops:

i need to do this in the next couple of weeks:lol:


can you tell me how i need to fill out the paper work and also do i need to pay the extra $15 per component because they are the new version?

so what is the total cost for a trade up to the newer esc. and also change the motor for a diff. turn


thanks so much:yes:

Hi entjoles,

I just checked our exchange program and was surprised to see that we have already opened up the HV Pro motor exchange to the new 5.5 and 7.5 wind motors. Learn something every day!:yes:

Here is how the motor exchange works: You can exchange your existing HV 4.5 motor for any other 5mm shaft HV Pro wind motor for $45 (exchange price) plus $10 (exchange fee) You really don't need to purchase a new motor, since the RMF motors all have a new 120 day warranty.

We will not be adding an HV esc exchange into the newest HV Pro esc (with built-in lipo cut-off) for a couple of months yet. But you will receive a RMF HV esc with all of the new programming that still requires an external 4cell Smart Stop module (not included). The exchange price is $69.

Just print and fill out one of the non-warranty (PDF) service forms linked at the top of both of the Replacement Options pages and follow the directions on the form. If you have questions, let me know.

Dispite any whining that may have come from my direction in the past few months Novak's is a stand up company that does their best to take care of their customers.

i think ill wait a bit longer than, as i want the newest version

thanks for the info
