While digging around my closet I came across an old Losi Mini-T. The battery in it was a ni-mh, and I couldn’t get it to take a charge. I have a small 11.1 volt 3S li-po I can use, will it work in my Mini-T?
Cubby- What’s up Gary, and thanx for the email.
Can you use a 3S Lipo in a Mini-T? Yes and no. If your Mini-T still has the stock electronics in it, No you can’t. If you try it you’ll blow the stock speedo as it was never intended to operate on that high of voltage (nor was it designed with a Lipo battery low voltage cut-off).
And Yes you can run a 3S pack in your Mini-T IF you install an after-market speedo and motor (this is assuming your 3S Lipo is up to the task). I’d recommend the Castle Sidewinder Micro with a 5400 kv motor. The wheelies you’ll be pop’n with this set-up will leave you smiling for hours. FYI, keep tire glue handy, you are gonna need it.
I have an E-max and have always wondered why it has two motors? Do you have any upcoming E-max articles in the works? I emailed you a question before and it never got posted. Walter
Cubby- So why does your E-Maxx have two motors? Because it looks twice as cool that way! Because it was designed in America where more is always better!
Ok… to get serious here- back when the E-Maxx was first released brushless systems and Lithium based batteries were rarely used in rc’s. So… to move all that mass with brushed and Ni-mh, Traxxas decided to tackle the problem by wiring two 6 cell (or 7 cell) Ni-mh packs in series and to run two motors. The batteries were wired in series to raise voltage in an attempt to keep current draw to a minimum, and the dual motors were used in an attempt for more torque and to keep heat down. As you’ve seen with your truck, it typically works pretty dern well, but it’s nowhere in the same league as a single BL/Li-po system.
Do we have any E-Maxx related articles in the works? Yes! We are converting an old E-Maxx into something new and bash-worthy, it should be finished up in a few weeks.
Lastly, I didn’t post one of your previous questions? Really? We get 30 questions a week here, and I typically answer 2. You do the math… but at least now you can sleep at night knowing you made the BSRC front page.
And with that, I must bring this weeks ASK Cubby column to a close. Send us your questions, rants and what not to Cubby at BigSquidRC dot com!
