MiniMono Esc doing things..........

[chirotray]

I'm having an issue with my esc at wide open. It fluctuates slowly between 75 and 100%. Anyone else have this happen?
Batteries have plenty of ass to them and it's for sure not a low voltage cutoff. Ideas?

[jharper]

Same with me. Thought the lvc kicked in but no studder. Checked Batt. It's at 11.95. Dunno??? Lemme know if you figure it out and I will do likewiseeeeeeeee

[Doby]

Ditto here.

Just fired off a E-Mail to Hobbico......lets see whats up.

Is the mini mono worth getting? Is the speed even good? What about the 17 inch off shore warrior brushless?

[Grimracer]

Hum....

On 3S right?...

The stutter comes in around 9.5 to 10V.. cut off at 9V..

If for any reasion your pack is not got the grunt to hold the voltage above that point its going to stutter. Remember this little hot rod averages around 14amps in a run.. Make sure you have a good pack.

Never the less.. PLEASE keep us posted guys..

Our buds at OSE have always been willing to hunt down issues that might crop up.

Thanks

Hi Mike:

I'm running 2200 Mah packs rated at 20C (I use them in my 23" sniper as well). Packs are new this season. (Had to do a bit of trimming of the hatch edges to make them fit)

[Grimracer]

Hey dude..

I have no idea what might be going on.. do you have an Eagle Tree? Can you run it with that and get some numbers for me?

If not thats OK.. but I have a TON of eagle tree data and so far have not had that happen. Would be good to compair notes.

Rocket and ROLL!

Hi Mike...sorry, no Eagle Tree unfortunatley.

Ran 3 packs through it and all did the same thing..

On the plus side, the thing handles well and only once got airborne going in to a 40 Mph wind!

So how come you guys can't design a boat that won't flip going full speed into a 40 Mph headwind......

If this is the low voltage cut off, it's not like any one i've ever dealt with. Its a very slow fluctuation, probably 2-4 second intervals. Mine starts doing it immediately. The motor spools up to a good rpm during the initial cavitation, but as soon as it hooks up it starts doing it.

chriotray,

That power cycling is the low voltage warning system. not the cut off.. When the ESC cuts off the boat stops will not work again untill you unplug the power and plug in a new battery. The goal is to give you plenty of time to get the boat to shore before it shuts down.

Doby.. lol.. the boat is a HOOT IN THE WIND!

Fair enough on the warning thing, but if this is the case, the sensors are set at too high of a voltage because it's kicking in immediately on every battery I have. What's the fix? It reminds me of the black jack, people were bringing them back to the store left and right bc the initial factory setting was nimh with a high voltage cutoff option, so you'd charge your packs and as soon as you put a load on it, the cutoff would kick in, but this was an easy fix with the program card. So what do we do with this esc? I'm hoping this is just a "bad" batch.

Ch,

Numbers are 10V to 9.5V to stutter.. and 9V to cut off.. Totally sounds like its not your fault "IF" you battery are up to the task.. (im sure they are). Without a data recording outfit like the Eagle Tree system we can speculate all day.. Best thing to do is contact Hobby Services (we put that in place just for emergency’s like this). They can help..

And the good deal with this is I know the people at HS quite well.. when a controller like this comes in I can get it and test it too.

Brian had one of these monos at the SAWs this past weekend... darn thing was ripping all over the place!! Looked like a ton of fun! I'm thinking pool-racing series!

[chirotray]

@Grim- I'll send it in, I can't wait to get it running legit. It's a helluva lot better boat than any mini rio out there. Handles like a baby delta force.
