Orion Big Block and LRP Quantum Micro Reverse

[MeddlE {work}]

Hi all,

Will the Quantum Micro speed controller be able to handle the Big Block?

Thanks in advance.

[armithius]

If the speed control can handle 10th scale motors, then it can handle ANY micro motor, this includes the big block. Yes the LRP can handle that motor with ease.

The Quantum Micro Reverse is specifically made for the HPI Micro RS4. On the box it says it can handle any 180 size motor. It has a rated current of 25Amps, can handle 4-7 cells (4.8-8.4V) and weighs in at 16g.

I can't seem to find any information on the current draw of the Big Block motor anywhere.

[armithius]

Okay there is absoultly no difference between that ESC and there normal one for the 10th scale, except the connectors. Anyways the stock motor pulls around 1-2 amps and the big block pulls less than 5 amps. Many 10th scale motors won't pull 25 amps. It will handle the big block fine. Although I like LRP and use ther ESC's, this new one seems like more of an advertising sales gimmick. I would rather save the few estra bucks and buy there normal quantum reverse and solder my own micro connectors on it.

[MeddlE {work}]

Thanks for that. The price difference here was only £5 so I thought I'd get the Micro version and save myself the hassle of soldering plugs. Also, the Micro version is a little bit lighter.

I shall take it home and install it tonight.

[armithius]

Excellent, you will definetly like the LRP. Keep in mind its lighter only due to the plugs. I have the Quantum SPort and really like it. Its very smooth and has great brakes. Just remember though that the braking power depends a lot on the motor. The big block, which I also have, has the least brakes of any of the motors that I run.

hey,

i was just looking around for the lrp micro esc, and can't seem to find it, i heard something a bout it a while ago, but never really followed up on it, coul someone just send me a link as to were i can find it?

thanks

If i am right you are prob just starting out is r/c cars? and i can tell you if this thing can handle up to 10 turn motors it will deffinately handle the micro motor just b/c of the micro name doesn't mean a thing except size you hav to read more about it to find out

[TFRMicro]

IMO, I think the micro reverse is not worth it...get the quantum reverse...because the specs are better and 5bucks less...

[MeddlE {work}]

First off, I have been racing 1/10th scale for about 5 years now, but I picked up a micro at the weekend. The specs on the LRP Micro Reverse do not mention 540 motor limits, they only mention no limit for 180 motors. I could not find any current draw figures for the Speed300 motors so had no way of knowing if the ESC could handle the motor.

Second, I believe that the extra £5 (that's GBP not USD) is worth the saving in time and hassle of having to solder (and purchase) your own plugs.

Third, I received an e-mail from LRP this morning stating "Yes...no problems with that one. Have fun with our QMR!"

Pyre, I bought mine from Apex models (http://www.apexmodels.co.uk/) for £69.95. Details are here - http://www.lrp-electronic.com/e/news_flash/news_e_20011023/body_news_e_20011023.htm

Just waiting for my 1800mah batteries to arrive now. 2 packs of 6 cells and a big block, should be fun.

[TFRMicro]

well the only info i know for this is the rated current for this esc is 25.

[xxtcrgp]

and I think the speed 300 is 10

Sorry if the last post sounded a bit, well, arsey. Thanks to all who have replied with useful information. Hopefully this will also help other people just starting out with a new toy. ;)

Batteries arrived yesterday, just need to charge them all up. What charging methods are you guys using? I'm figuring on using my supernova 250s as it can handle 1-25 cells and nimh.

Once again, thanks.

You don't have to purchase plugs, the micro comes with them. Anyways, I use a Quantum Sport. Awesome ESC and a tad smaller and lighter than the Quantum Reverse. I guess reverse is okay for fun and games. But it's not allowed in racing. Just something to consider. Not too sure if the Reverse model has a lockout or not. But, you can't go wrong with a Quantum on your micro.

One side question for you guys that have a Quantum Sport, have any of you ran it in a 1/10th scale Sedan with a Stock motor? Just wondering if I'll end up frying it or not if I put mine in. I know it says it can handle down to 14 turns but thats not always the case. Quantums have been a little "hokey" when it comes to this. Especially the Quantum Comp with mod motors. Just asking.. Gonna try it out on my Stock Tourer. I normally use a GM V12xc for my Mod. Awesome speedo! Anyways... have fun!

[KilRuf]

A safe bet for charging is 1amp. That's how I do all my "small" batteries. If the battery is nice and warm.. it's charged. I use a Novak M. Pro and an Digital Intel Peak. They both work good.

[MeddlE {work}]

Ok, I charged one pack at 1.8A and they got way too hot. Second pack at 1A and that was perfect.

[TGRupert]

try using a fan, helps a little

[MeddlE {work}]

Strange that you should suggest that, it is a current project. I'm setting up a twin 8cm 12V fan rig that the batteries sit between while charging.

[TFRMicro]

make sure to show us, when you are done.:cool:

[Turbo Cloud]

i bet those will stay a little cooler while charging

[KilRuf]

Dont use a fan on NiMh batteries when charging.

[xxtcrgp]

why not?? people do at my track:confused:

[MeddlE {work}]

I believe the reason for thinking that is that the outside of the battery feels cool while the inside is cooking. I will still be charging at 1A so internal temp shouldn't be a problem but it could reduce overall temp of battery.

[TFRMicro]

if you keep a fan on the battery when charging...

I think the battery will never get charge all the way up...since its still cool...

[MiMicro]

It's only cool on the outside, not the innards.


You dramatically reduce the life of NiMh's by cooling them while charging.
