ESC for Super Stock BZ in TT-02B

[Empty_Hand 203]

Question for the Tamiya Club brain trust:  

I’m a newbie and to date have only run a Grasshopper and Hornet, both using brushed motors and TBLE-04S ESCs.  I decided to dip my toe into the modern waters with a TT-02BR that delivers today.

I purchased a SuperStock BZ motor based on a few threads I read here as I’m not wanting to skip straight into Brushless/LiPo (still terrified of those batteries!).  I’ll run this with a 5000 Mah NiMh battery using a Tamiya plug. 

Question:

I’ve come across a few threads bemoaning the TBLE-04S for overheating and I’m concerned this may be the case given the draw of the Super Sport BZ and the high torque steering servo.  If this is truly the case, can someone recommend a good quality alternative ESC that I can grow with?  Perhaps even using with a Brushless 13.5T motor when ready?   I now have all parts for the build short of an ESC and would like to place an order this weekend.  

Primary use is thrashing around a park in mixed terrain (grass, wood chips, ball field dirt, gravel, etc).  Not for anything formal.  

Thanks!

The BZ won't run on a TBLE-04S as it's out of spec so I'd suggest a Carson Dragster, Hobbywing 1060 or the new Tamiya brushed ESC made by Hobbywing the THW-1060-RTR.

All three are brushed motor compatible only, so if you decide to go brushless in the future you can either use a TBLE-04S from one of your other cars (swap it for whichever brushed ESC you're using with the BZ) or buy a new brushless ESC.

I run Hobbywing 1060s in most of my Tamiyas, it'll run almost anything down to 15 turn motors ,it's easy to setup, and they're waterproof.

if you want better braking (and setup options), a Hobbywing 1080 would be a hood pick. Bonus points for coming with an XT60 plug (which is a better plug to "grow with" vs an old molex connector).

Thanks, looking at the 1080 now.  I like the idea of the XT60 plug for future proofing.  

Do you recommend a fan?  The TT-02BR has an enclosed body and airflow looks pretty restricted.

You shouldn't need to worry about overheating either the 1060 or 1080 with a Super Stock motor on a 6cell nimh. The motor itself would likely be the component that gets hot depending on gearing.

While there is nothing wrong with using nickel cell batteries, you should not be scared of lithium batteries.

XT60s are both better for higher power motors, easier to handle/fit, and if you decide to move into LiPOs later on it opens the door for that. The HW1080 also comes with a programming card if you feel like adjusting the acceleration curb, braking, etc.

You may need to solder the connector onto the HW1080, it's not hard and its very valuable skill to have, even outside of RC.

A fan couldn't hurt, you can always trim a "vent" into your body shell to improve airflow. I think @skom25did something like that on his.

HW1080 doesn’t come with the programming card any more.

I am not able to say anything now, but after first two packs I have feeling that small vent improved air flow a bit.

Super Stocks are great motors. Maintenance is also very easy and can be done in 20 minutes.

TT-02B is very similar to the DF-02 it replaced, which I have a bit of experience with.

This will depend on how you gear the chassis too; as the big wheels of the buggy mean that things can get hot real quick. I've had a HW1060 overheat with a Sport Tuned motor (less amperage than a BZ). If you plan on running on smooth surfaces like car parks and compacted sand / dirt, it'll likely be OK for a bit of light bashing. As soon as you really want to lean on the ESC they quickly overheat and the 1060 doesn't have the ability to mount a fan to it (to the best of my knowledge) but a 25mm fan can be mounted to a 1080...

Thanks all. HW 1080, fan and programming card now ordered.

I usually use zip tie straps to mount fans onto my ESCs, it looks "sloppy" but it saves me the trouble of hunting down screws!

What do you mean by "lean on the ESC"? Just curious. I have actually never managed to get an ESC warmer than stone cold, and I live in Phoenix 😅 so I have always been curious about when people report issues with hot ESC's. The motors though are another story and always seem to get searing hot no matter how low I gear them and even with a heatsink mounted fan. I was forced to switch to brushless on certain cars for that reason.
