sweet!!!! will i be able to send in a hvmaxx 4.5 system and upgrade to this when it makes it to market

I'll collect your comments and questions for Bob and Adnan (Novak's senior design engineer). I'm merely a conduit, an intermediary.

We offer the 540 motors in 11 winds, so adding a few more 550 winds shouldn't be a problem. The original HV systems were designed as drop-in replacements for the brush electronics in the E-Maxxes.

How things have changed in the last few years! When we released those systems, I don't think we had ever known anyone to use Lipo batteries.

im sure that it will be a good system once it gets done, i really liked my hvmaxx system

i think the lower winds are a great idea, alot of people like the "systems" that are tested and matched to specific applications

thanks for the update. can you let us know what the planned voltage is for the new hv system? I currently run 5s and plan on going to 6s but want to make sure your new esc will be able to handle that.

I love your motors for 10th scale but dont use your stuff in 8th scale basically because of the esc. Could never get it to run more then about 10minutes with out thermaling in my e-maxx.

The new HV esc will be max 6s lipos. After reading these, and ther, forums, I told the engineers that if we couldn't design a new 6 lipo controller to just forget it. Our existing HV products are way overdue for replacement.

thanks and I look forward to seeing the final product.

Great, this is a big step forward for electric. We have at least two compainies bringing out 6s sytems with motors. This will go a long way to bringing larger scale electric to the masses!

A sensored 6S system? I'm gonna like this...

[Serum]

This sounds very promising;

6S, 5mm shaft, wider range of KV.

Now the next step is to upgrade the rotor to a slightly larger diameter to increase the torque, to enable the use the full potential of 6S; i think that because of the smaller magnets, you will hit the limits of a motor sooner. (copper and iron losses)

[gixxer]

everything sounds good. now as long as you guys can get it out on time you will have my $$$$.

Bob posted a response on a forum at RC Tech that I will repost here.

Questions: .....Superior to what? What was used as a comparison? Was this the current HV setups or something else?

Very interested to see some more detailed shots. The 4 bolt design sounds like my RC Product Designs mount as it goes on with 4 bolts.

I like the size of the fan. How durable is it?

Last thing, and its probably a wording thing but I figure I ask to be sure, these conversions, are they compatible with the truggy version of the buggies listed?

Bob Novak: I have not seen your RC Product Designs mount. Let me explain how ours works. The heat sink replaces the center sleeve on the HV motor. There are two screws that clamp the heatsink to the laminations of the motor. This heatsink is common to all the conversion kits. There is a car specific plate that screws to the the bottom of the heatsink with four screws. This assembly is then screwed or bolted (depending on the Buggie) with four screws or bolts thru existing holes in the chassis.

Mounting this assembly to the chassis gives superior heat dissipation compared to mounting the motor at the front. Clamping the heatsink directly to the motor laminations also gives superior heat dissipation over motors that cannot be mounted this way. This heatsink will fit on any of our motors. The fan is also very rugged. These conversions will most likely fit on the Truggies also, but I just have not had time to test them. That will be my next project.
Thanks for the comments.

any idea on a price range yet?

List price is $139.00. Street price may be @ $90.00.

This all sounds great.

Do you expect the new HV products to be race grade like say your GTB line or more consumer grade like say your XBR line?

They will probably be both, with a high end BL racing controller and a revamped 2-4s lipo HV-style controller---many users don't need anything more than 4s. We also sell quite a few Super Duty XR brush controllers for the E-Maxx size 1/10 scale trucks. The HV/Monster esc redesigns include several different products.

Then, there can be 1/8th scale electric (BL) racing....
