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

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.

We struggled to get the perfect setup. Back then the cars were weaker, the speed controls were mechanical, batteries had memory, but life felt simpler somehow. Today we are spoiled with what is available and the kids in the hobby take it for granted. Sometimes I miss the old days. Thank you and I appreciate your comment 😎👍

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.

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.

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

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!

@AJJAMStudios Жыл бұрын

That is not how it works. The C rating has little to do with capacity. You can have a 5200 mAh battery in 20c or 120c. Power draw or amps is the safe amount of current the battery can handle without damage. What you refer to is charging amps. For a 5200 mAh battery 5.2 amps is the max charging amps you should use. A 2000 mAh should use 2.0 charging amps and so forth. This has nothing to do with the C rating. I hope this helps and thanks for asking. You should check out RC batteries 101 in our 101 playlist. It’s informative 😎👍

@@AJJAMStudiosnot true, a 20C 5000mAh battery is rated for 100A discharge current, vs 20C 1000mAh would only be 20A

@SinuheSieda 2 ай бұрын

C value is discharge rate of capacity. 25C is 25 times its capacity, which give us max amp drawn. For 2000mAh(2Ah), 25[C]×2000[mAh]= 50'000[mA] = 50A

@richard-rc8605 8 ай бұрын

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

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!

@AJJAMStudios 6 ай бұрын

Not all pinions are equal. Some are softer than others and wear faster. Perhaps a better pinion would help. 😎👍

@nickpacello2597 Жыл бұрын

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

@AJJAMStudios Жыл бұрын

Anywhere in that range should work. 😎👍

@SinuheSieda 2 ай бұрын

Rule or thump is you can not touch it without burning your self if it is above 60°C. (120-130°F = ~49-54°C)

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 Traxxas e revo 1/16 scale the 4x4 n I have been running the vxl speed control n motor with the stock spur gear but I got it used from a friend n he beat the heck out of it then I had to put some tlc into it but the tires was wore down so I bought some aftermarket ones to put on it it's been running fine oh ya the pinion gear my friend gave me n said he thinks that was the one that was on n it but anyways just here recently the motor n esc started getting hot so I lowered the pinion gear from 23 to 21 now will that make it run hot or run cooler?

@AJJAMStudios 3 ай бұрын

Lowering the pinion size should cool things off a bit. Check your temps to be sure. The tires, if they are heavier or a bigger diameter, will still add amp draw and cause heating of the ESC and the motor, so be careful until you get your temps down to a safe level. Thanks for commenting. 😎👍

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

@AJJAMStudios 11 ай бұрын

Not true. More resistance = higher amp draw. Bigger pinion = more resistance.

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?

@AJJAMStudios 9 ай бұрын

Gear setup is touchy at times. Making sure your components are all using the same pitch is one issue that can pop up. Also the spacing between the gears is critical as well. Then there is the parts themselves, plastic, aluminum, or steel. Some hold up better than others.
