HV ESC Option

[MetalMan]

The actual ramp-up time can be adjusted with the programming card, but on any setting it has a slow-ish motor startup. After it gets the motor going, acceleration is pretty much only limited by the setting you choose.

i have one, but i haven't played with it yet. as far as rampup, my onroad takes off faster than traction allows.

[MetalMan]

Yeah, it definitely will limit the car's acceleration to the traction the tires can provide. In my MT2 (4wd), after maybe half a second of grabbing WOT it just spins completely out of control.

The card very good for programming. I have start mode on 'normal' (As opposed to soft or softest) governer os off, and timing is on normal I think... I will have to increase it and see if it gives a little more punch.

Hmm, the delay doesn't sound bad enough not to consider it as a viable option. I was thinking of using this stacked setup for my hi-speed project, but need a high V ESC with a good amount of current headroom and thought a pair of these ESCs would be an inexpensive setup.

Hmmm. Do I get two of these an experiment for about $200, or just get a CC HV-110A and deal with the fairly low current rating? Decisions, decisions...

[Sammus]

What about the option of getting the Turnigy Sentilon and dealing with the fairly low current rating :) After all, its the same as the CC HV-110 isnt it?

How high V are you planning to run? A few people were after these a while ago, and they have just got in new stock...

I haven't completely dissected the Sentilon HV but it does appear to have a sperate FET and control board if thats of any value...I guess a 'maybe' isn't good enough when $200 is at stake lol

Aside from the manufacturer's ratings, they're quite a bit different. HV110 has stacked power boards, making it taller. Sentilon is just one flat board. CC has good service (they replaced my burnt HV110 for free!), and I haven't tested or heard of the warranty or cost to replace/repair on the Sentilon. The HV110 is much more programmable.

Yeah, I need an ESC capable of 10s (12s preferable for a little headroom) AND high currents over 100A. Not too many of those around at anything resembling a decent price. The HV-110 is my other choice, but it's only rated at 110A with not much current burst headroom (typical of air ESCs). And MM is right, the 110A is already stacked so more stacking makes for a large ESC, not to mention pricey.

With the Sentilon's single board 100A layout, adding an extra layer should be fairly simple. And would give me a solid 100-120A continuous rating with extra room for bursts up to 220A. Even buying two of them and modding for stacking is still pretty cheap at $200. Can't even get one HV-110 for that price. I too don't know about the warranty cost for the cheaper ESC, but for that price, I'd take the chance if all other features work for what I want. And TBH, I don't use all the programmability of any of my ESCs, so that's not too important.

Yeah I was only talking about the ratings... probably should have made that clear

It was semi tongue in cheek anyway, I'm pretty confident that the HV-110 would outperform the sentilon :)

ESC is good but as I told in some threads its only good for Speedruns or Drag Race thats all. It not heating up at all realy cool stable SMOOTH ESC. Stupid delays screw everything. You goung from corner and press trigger it not move properly and suddenly after 0,5sek you loosig control in oversteer or going to jump and try correct trajectory and realise that nothing happends and when front tires land its going in full power, I even blown my LSP font diff. OK with time you accustom yourself to those delays, but after 10seks of constant power no startup delays (its made for helis for tight situations) and again after sek not tuching a throttle it spin up slowly and impossible to accustom yourself.
Damn I will be very happy if somehow will be possible to hook MM brains to it. I will do this mod 100% and try out HV system

[BrianG]

Hmm. Speed runs is what I'm mainly after, but would like to have it usable for just parking lot running. I guess I'm stuck with using a fairly low-current HV-110 ESC.

It would be really nice to have the "ideal" ESC though. Now, I'm thinking about using the brains board from a HV-30 and then multiple FET boards from the Selinion... So many experiments and ideas, so little money. :(

[Sammus]

For what its worth I don't agree with tom255, the delay in mine seems to be only evident accelerating from a stand still. If your rolling slowly then its very punchy still. I'll get some vids up when I can find someone to hold the camera for me...

[tashpop]

i too have no delay. only from a dead stop, after that its all smooth and responsive like you would expect.

tom255, did you try with a different radio system just to see if it was a combatibility issue?

[starscream]

I have both the HV110 and the Sentilon.
I raced the Sentilon last Saturday in my MBX5T. The performance was good but not up to par with the HV110. I too experienced the delay in power during initial start up. I tried many setting changes including throttle expo on my radio but nothing helped. I didn't try soft or very-soft start up but these settings seem intuitively un-helpful. As stated before, the ramp up only occurs from a dead start as punch power is readily available if the vehicle is already in motion. This esc also seemed a bit lacking on WOT as the HV110 just seems to supply more power somehow
The Sentilon is a great controller for the price but for racing performance in a car/truck the HV110 out performs the Sentilon.

[tashpop]

that seems fair. i noticed a difference just like that when i replaced my bk9920 with a mgm16018. seem to have more power up top.
