3S on a Rooster

[Monstergt]

Can I get by with running 3S on a Rooster? If I can is there anything I should look out for?

[mudn_1]

I am running 3s on a rooster with an integy 45t motor with no problems..... there isnt a cutoff for it, so you have to keep track of the time running or shut it down at first sign of lost power.....

[Monstergt]

Thanks that's what I need to know

Yepp, I have run 3 cell on a rooster....
The only thing you need to look out for is the voltage, like stated above.. and look out for the power increase

I run 3S on Rooster with 55t...get a Novak Smart Stop Lipo cut off for 3S and youll be all good,,,cheap insurance,,,ive run this way for months

hello! I too have a Rooster esc. 87/12 spur and pinion I have a 35t. Will the 35t cause overheating with 3s? Sorry for the thread jack

[wurster]

I run a 3s with a hh 35 t pro motor and no problems lots of wheel speed and power.but you might want to run the lipo cut off.

I assume you guys are talking about the Rooster Crawler version, what about the Rooster T-12 ESC? Same basic guts but different profile?

[oscodawave]

does the lipo cut off not work with 3s? only 2s?

[out4crawlin]

Well it is designed to use a 2cell lipo or 7 cells, so the only lipo cutoff it has is for a 2 cell battery.
It will handle a 3 cell tho, because it has a good 5amp intenal bec

so let me get this straight!! i will not fry my rooster crawler if i use a 3 cell 11.1v lipo? i was thinkin about getting a tekin fxr so i can use 3 cells but id rather save the money and use what i got! just need an external lipo cutoff?

To use a Rooster CE with 3S you NEED to use an external BEC, and go no more than 45T motors for safety. Period.

I fried one without using the external BEC (Castle BEC) with a 55T Holmes. I also fried one using a CCBEC and a 40T Holmes.

I ran one for over a year with the Holmes 55T, CCBEC and 3S. I sold the rig to a buddy with the same setup, but he uses saddle packs that are 9.6V and has no problems. He just won't upgrade to lipo.

so whats the bec do? sorry im just now started to figure out electronics setups, i have a 55t novak motor

The built in BEC will not handle servo duties and send power to the motor over a certain voltage. An external BEC (Search "CCBEC" and see the results), such as the Castle Creations BEC takes voltage directly from the battery and applies it to the steering servo regardless of throttle position. IE: I can only steer if I'm off the throttle. Once back into the gas, you can't turn. The RoosterCE will give throttle priority over steering. You get into a bind and can't steer.

You need a BEC.

Great info. I was wondering this stuff myself. I love this site.

ok i see, now do i need a external lipo cutoff? cause it says earlier in this thread the rooster only has a lipo cutoff for 2 cells?

I've never seen anyone run 3S on the Rooster successfully, they always shut down due to heat. But, I don't think they were running a BEC either.

Rooster Crawler on 3S, add:
- External BEC
- External 3S Lipo cutoff

[kmnss]

I never used a cutoff. I just made sure to check voltages before, during, and after running it. If I used a smaller battery, I tried to time it. The cutoff would be a safety measure for the battery and isn't 100% necessary as long as you pay attention to voltage.

[M1tch]

i have run my rooster crawler with 3s for 2 hours at a time and not had a problem. i use an external BEC to power the steering servos, but not a CC one as its hard to get hold of them in the uk. i just use the built in BEC to power the receiver

[deserthobo]

This gets curiouser and curiouser...Instead of an external low battery cutoff why couldn't a low battery alarm be installed...I have one for the 3S and it supposedly monitors all cells and sounds the alarm when voltage reaches the thresh hold. Just wondering...
