Dual motor ESC question: Experts pls help!

[huasze]

Hello, I'm trying to setup 11 turn dual motors on my Tamiya Wild Dagger. But the problem is that, I can't seem to find any ESC that specs no turn limit for dual motors, only for single ones. Would it be safe to try it on ESCs that have no single motor limit that also include thermal protection(switches off when gets too hot) like the LRP ipc7.1 or LRP F1 pro reverse? therefore if the speedo can't take the motors, all it does is to stop until it gets cooler or when I change motors.

Pls advise and thanks in advance!

Novak Super rooster, or a Tempest Pro, if you can find one, will handle them fine.

No they will not. The super rooster can only handle down to dual 15T motors. 11s would fry it. Theres 2 routs you could take. 1 you could wire the motors in series and it would give them each half of there power but any ESC that could handle a 11T motor could handle it. Or you could use 2 ESCs and 2 Batteries for the motors. I tried this on my TXT-1 and had mixed results. It worked great until one of my ESCs fried. And this also adds a lot more weight to the vehicle. Or you could get some milder motors and use them but unless you wire them in series or go to dual ESCs it will be hard to work.

On my wild dagger I ran dual 19T motors in parallel on a rebel reverse esc(im using this same set up on my TXT-1 now to). It worked fine but with plenty of torq but no speed and as you know the wild dagger only has 2 gearing options unless you get a pair of these

Personaly if you can i would go with a Super Rooster ESC with a 10 cell pack(dont know how you would fit it) with the 11s in series. Or if you got the money go with dual 15s in parallel.

Though I haven't tried running motors with less than 17T on my Super Rooster, the instructions state:
Motors in parallel double the load on the speed control. For this reason you should not run motors with fewer turns than are available in a single motor. For example, if the lowest number of turns you can get is an 8 turn motor, each of your dual motors should be 15 or 16 turns.

What this tells me is that you should be able to run 11 or 12 turn motors in parallel because the lowest turn motor that is available over the counter is six turns.

The question is this: has anyone tried using less than 12 turns on a Super Rooster in parallel running six cells?

You are wrong. I have seen a Tempest Pro handle 2 11 Turns in a mod clod, so, yes I know that the tempest will work.


But you can go with the super rooster and maybe change your motors to soemthing a little higher

[krisI.925]

ya i dont know the specs on the tempest. So ya it would work if you can find one.

tower hobbies says
"Novak recommends that users stick with 15-turn motors in parallel, while any wind in series will be safe."

but this could be for 10 cells tho. If you are just running 6 cells you could probably use it with out frying it but i wouldnt recomend it.

[huasze]

ok guys, i think i got what it means by 15 turns parallel. it means 15 turns parallel with 10 cells. at 6 cells, it probably could hit dual 9 turners without a problem, as what someone in another section has been telling me

[krisI.925]

the Super Rooster can take a lot. I saw one guy at my lhs the other day with dual 10 singles in his clod on 6 cells in series. But he had a fan to cool the ESC. Which is what a suggest u do.

[huasze]

great...i'll go custom-make a fan for my F1 bullet reverse. thx!

well i run esp 14t motors with a seven cell pack and have not had any heating problems. i have my super rooster mounted high in the chassis so it does get a lot of air flow across it. i touch the heat sinks each time I get done running a pack and it does get warm, but not so hot that I can't put my finger on it. and I do turn around and drop a second battery into it and go back out driving. actually the batteries get hotter then the esc's heatsinks.

well then there ya go then. And I recall that the F1 Pro can handle dual low wind motors better than the super rooster can. But you will want to add fan just to be safe.

And BTW i hope you have a good lathe. Because you will be using it very often.

[huasze]

sheesh...no lathe! :(
