Super Clod with powerful motor?

[Clodbusterfan]

I am using the old version of this ESC: https://www.hobbywingdirect.com/products/quicrun-880?variant=18212301930611 which was the 860. I am currently using 19 turn motors with the 860 on my Super Clod. Will the 880 handle 17 turn or 15 turn dual motors without frying? https://www.hobbywingdirect.com/products/quicrun-880?variant=18212301930611

Will the 880 handle a hotter motor than the 860 did? And will the Super Clods gearboxes handle 2, 15 turn brushed motors?

Here is the motor brand I would be using:

https://www.amainhobbies.com/reedy-radon-2-3slot-brushed-motor-17t-asc27426/p947544

I will be using a 6 cell nimh battery.

Would I need to lower my pinion tooth gear? Sorry but I have no clue... what size pinion does the Super Clod come with?  Thank you guys for all your time! Or would I be better off with 2 silver cans and a 3s or 4s lipo?

The turn rating for tht ESC appears somewhat ambiguous. On one hand, the manual states a 12t limit on 6S NiMH/2S LiPo, but then it also states that motor turns should be increased when running dual motors, and it doesn't say by how much they need to be increased.

Personally I have never really bothered with dual output ESCs for my twin-motor builds, since most appear to simply have two sets of motor wires in parallel, fed by a single power unit. You can therefore achieve exactly the same thing with a single-motor ESC and a Y-harness. When choosing an ESC for such an installation, go for one rated to half the turns of your motors. So for a pair of 15t motors, you'll want an ESC rated down to 7t.

Another even better way of doing it is to get two single-motor ESCs and run them each off a separate channel, or via a Y-lead if you don't have a channel spare. You can have plenty of headroom if you pick up a pair of 1060s, as each will easily handle a 15t motor on its own.

And regarding those motors: they are very basic and cheap Chinese generic things bearing a Reedy label. You can often get exactly the same motor for less under a different brand, or no brand at all. Look for brands such as Austar and Surpass for example, or just search "540 brushed motor" on Ebay. I see amain even sell the Yeah Racing Hackmoto range, again exactly the same motor with different branding, for less than the "Reedy".

10 dollars cheaper for the same motor with a different sticker!

[87lc2]

The 880 is a great ESC, I run it in quite a few of my Clod based trucks.  In one truck I'm running the 880 with 15t Firebolt motors (stock 13t pinions) and have had no issues on 2s or 3s power.  Here are the specs from Hobbywing if you're interested - http://www.hobbywing.com/goods.php?id=650   They say >= 12T on 2S and >= 18T on 3s, but I've had no issues and have run this truck a lot. 

If you want a decently quick Clod without going brushless 15t motors with stock pinions on 3s is a good way to go.  Don't bother running 15t motors on 2s, not enough torque and it will be slow.  Gearboxes will be just fine, Clod gears are tough.  You need to be running dual brushless under 3s to do any damage, and even then they usually hold up just fine.  

@TurnipJF is correct on the motors.  I run a Radon 2 17t motor in one of my SMT10s for spec racing and it's a decent motor, but not any different than the cheaper options available, they are the same.

More power?

On a clod???!!!!

Are you insane????

Join the club..

Some say that when you accelerate with a Clodbuster, it doesn't travel forwards, it pushes the world backwards..

All we know is it's called the Clodbuster..

[Clodbusterfan]

Wolfdogstinkus: That was amazing! DIdn't know a Clod could do that!

87lc2:  What type of 3S LiPo do I need? 100C or more or less? Will it do too many wheelies if I run a 100C?

You really only need a battery that's rated to the max amp draw of your electronics setup.  The battery only supplies what the ESC asks for, it does not push current to the ESC.  With the an 860 or 880 and brushed motors, a 50C battery wll be fine, and that's what I use most of the time with no issue.  Nothing wrong with using a higher C rated battery, but it's not going to give more performance.  Maybe slightly more punch, but I doubt it would be super noticeable.  With 540 brushed motors in a Clod on 2/3s you will not be doing uncontrollable wheelies so no need to worry about that.  If you want that (along with all the parts that will break) then go to 4S or dual brushless systems.

I might have been wrong about the reverse rotational world????

That's only what some say.. 

I tend to go 2x brushless motors, 2 batteries and 2 ESC's but that's only because it takes me too long to tell the difference between series and parallel. Lol, so I find it easier to have separate ESC's with more punch set on the back esc.. 

My 6wd wants to wheelie, I think it would if I glue the tyres..

I do also run 3s on the back sometimes for fun,, which is also easy with 2 ESC's and 2 batteries..

[Clodbusterfan]

Thats funny you mention 2 batteries and 2 esc's because I was thinking of the 1 esc and 2 motor option with the Traxxas EVX-2... Do you guys think thats a good route?

[Clodbusterfan]

I am actually not going with the Traxxas EVX-2... I heard it goes through motors too fast with that much voltage. Would I be able to use a 3s lipo with a 19 turn motor and the Hobbywing 880 without burning up the 880?

[87lc2]

The 880 will be fine with 19t motors.  As long as you keep motor temps under control 3s will be fine.  However, with more voltage you will go through brushes faster, no way around that.  If the motor is rebuildable (the Radon is) then you cn replace the brushes, if it's a sealed can you need to replace the motor.

[MICHAELs TopForce17]

2 silver cans are also good.

[Clodbusterfan]

Is this the team brood you mentioned?:

[TurnipJF]

That Brood one looks interesting - the same basic motor as the Reedy, Yeah Racing and others, but with soldered brushes, zero timing and possibly other internal fettling.

[Wooders28]

I've a bullhead with an 860. 

Ran it on silvercans on 3s for a while and it's now a pair of 15t firebolts on 2s with no issues.

Speed wise, it's about the same as the silver cans on 3s, but not had a chance to get the GPS meter on it.

Silver cans 3s -

 

Firebolts on 2s, sure it was only at 80% EPA, as I'd said to my daughter, if she could go full speed and stop before the summer house, I'd put it up to 100%...

 

[Clodbusterfan]

So would 2, 17 team brood and a 3s lipo burn up the motors super fast? And would the 880 ESC be able to handle that voltage?

[87lc2]

The 880 will handle 2 17t motors on 3S just fine, no worries there.  As far as how long the motors will last that's anyone's guess.  They should be fine though, they are rated for up to 14.8v input.  The motors themselves will be fine, you will just have to replace brushes more often than you would when running on 2S.  Anytime you run more voltage the brushes will wear faster, no way around that.  I would give them a shot, looks like a decent motor for a Clod.

1. Was sure that lite Girl was running straight into the wall for a moment

2. I always get anxious when driving or watching other drive on a Road/parking lot with a lot of Curbs, those are RC killers!.

So i had to take a rest before i could be able to ask  the Question. I never got so far to understand what 17T - 19T - 15T really is and what the point of this is, sure its about size and turns but why is there a difference and what does the difference actually do?, so you even should program the ESC when changing to a different T on a new motor. 

[87lc2]

Actually, turns doesn't have anything to do with size.  Motor turns is how many times the wire is wrapped around the armature in the motor. More turns means a longer wire and more resistance (less speed). A lower turn motor has an overall shorter wire length which offers less resistance and more speed.  In simple terms, a lower turn motor offers more speed and less torque while a higher turn motor offers less speed but more torque.  

Motor size is exactly that, the size of the can.  In RC you typically have 380 type motors, 540 type motors, and 550 type motors with the number referrring to can size (there are other sizes, but they are not common).  The larger the can the more torque.  Also, a similar turn motor in a smaller can will be much faster than the same turn motor in a larger can, i.e. a 12t 540 motor will be a lot faster when compared to a 12t 550 motor in the same model.  

I'm no expert by any means, but that's the basics on brushed motors.

I have tried 2x CoreRC 15T motors with my 880 and it cuts out (although someone on the forum has managed to run 2x15T Firebolts on an 860). Are there ESC settings that can reduce the chances of it overheating? Thinking about the punch setting - if that is turned down, would that reduce the current draw on acceleration?

I don't think there are any settings that would help, sorry to hear you have that issue.   You are running the fan that comes with it, right?  Other than that not sure what else you could do to keep it cool.  Have never had mine cut out with 15t motors on 2s or 3s.

Thanks for the reply - I don’t seem to have much luck with ESCs - my 1060 went into limp mode constantly with a 13T motor so I added the cap pack.

I don’t suppose I can complain - the specs say that for dual motors it should be 24T+ but it is odd that others have managed it! I’m on the stock pinion too.

I have just tried failing back the punch with the program card but it still cut out. Looks like a pair of Torque tuned motors for me!

Torque Tuned motors are great!   I run them in a lot of my Clod based trucks on 3S and thet move as fast as you'd need a Clod to go in my opinion.

I feel your pain on ESCs, I've had a lot of bad Hobbywing 1060s lately.  Think I've trashed 3 of them in the past 6 months or so...also had a lot of issues with the 860s in the past.  All of my 880s and 1080s have been good, have 20-30 of them.

Using the same 2s? 

I found issues in some cars, when using a low C rated lipo, the voltage drops under the cut off ,under heavy load.

I thought ,as they where directional motors, they didn't work well in a Clod? (As one motor runs forward, and one runs in reverse)

Don't think they're directional, run them in a few Clod and they work just fine.

In my limited experience I have found the 1080 much better than the 1060 In terms of reliability.
