RC Gearing 101 

Just come across your channel, i know, a bit late, but very educational. As an intermediate at this hobby, gearing always confused me. Learnt more about gearing in this video than ever before. Thank you very much.

Back in the 80s we were using 6 cell NiCad batteries for racing. You had to gear the buggy to last for a 4 minute race. If you did it right the battery dumped just after you cross the finish line.

Ok so now I’m aiming for 101 pinion and 101 spool perfect!!

Thanks for taking the time to record this. Very useful for someone just getting back into the hobby. Thank 👍

Excellent content as usual , thanks for covering this complex subject 👍👍

Excellent 101 video. Will share this well explained video with a few newbie RC enthusiasts.

Awesome explanation and walkthrough. Tons of great information AJ. 👍🏼

I really like this Channel! Its really good and he knows pretty much everything about RCs. Really great videos. Very professional 👍👍

Really a great video! Thanks so much!

Thank you for another great video. just being use to taking off the body and just going by touch was my normal. im going to get more technical now and get my old nitro temp gun out next time.

You’re the best! Thank you for sharing your knowledge big dawg 🫡

Always good thanks👍

This is a great video and I learned a lot from you (and subscribed!) but, correct me if I'm wrong, isn't "1C" equal to the total amp hours of the battery? i.e.: for a 5200 mAh battery 1C == 5.2 amps and thus a 50C, 5200 mAh battery would be able to provide 50 x 5.2 amps max. Am I wrong? You seem to imply that "50C == 50 amps" regardless of the mAh, but I totally could be missing something! Again, great video!

Awesome!

Great Video a lot of information

AAA plus again great video.

Cool

Thanks for the lessons! Would you please do a motors 101?

I'm looking at gears online for my SCX10 6X6 so I can get a general idea of what to get at my local hobby store and I've noticed some gears have a pitch number and others don't. What exactly is the gear pitch? I've seen 32p, 36p, I think maybe even a 48p, I can't remember. If a spur gear has a 32p, does the pinion also have to have a 32p in order to work properly? What about the gears that don't have a pitch number? Can I use a 15T pinion with an 87T spur if both gears don't have a pitch number listed and are made of steel? My 6X6 has a dual motor set-up (I'll be using 2 brushless) mounted to the single speed transmission and all 3 differentials are spool type. I have 2.2 wheels with aggressive, deep cleats in the rubber for maximum climbing capability mounted on straight axles (not portal).

I have a Team Associate Sc10 2WD with 87T spur and 17T pinion mated to 12-turn 550 Traxxas Titan brushed motor. It burned down Radiolink Cool 9030 (90A rated) and ISDT ESC70 (70A rated) escs on both 2S and 3S LiPo batteries at 50C rating. I went to a hobby shop, and they told me to up the pinion gear so it wouldn't pull so much amperage because smaller pinion is higher torque = higher amperage true

AJ- great educational video!!! So should we shoot for 120-130 motor temps for the sweet spot?

Still got more questions

Bonnie X-maxx change pinion gear many times, slip self righting time😓

Hi there I'm stumped about my pinion gear on my Tamiya konghead.i installed a 6900 kv brushless and a aluminum 18 tooth 48 pitch pinion gear and it gotten chewed up but the drive gear was almost unfazed.how did this happen? subscribed!

Friend, please help me, I'm new to car modeling, I built an onroad car, with a 64pitch pinion with 40T, and a 64pitch 96T spur gear, I use a hobywing 10bl120a esc, the futaba 3pv radio has the end point at 100%, the 10.5T Brushless engine for 1/10 cars in the few laps I drove, the spur gear damaged all the teeth, how can I be doing so that this doesn't happen?

9:16 : sorry but I think you make a mistake with C rating to get the amperage you have to multiply C rate by the battery capacity 5200MAh x 20C = 5.2Ah x 20C = 104A your battery can provide 104A and not 20A - 1C is not equal to 1A I (current of discharge ) = rated energy batt (Ah) x C rate

Everything was completely snug and didn't happen immediately.just one day crunching sounds.
