    Dropping pinion tooth on motor, gearing down, will help enormously. Yes, you will lose some top end, but gain much on low end.
    Many non-sensored brushless systems such as arrma big rock, come with a 15 tooth pinion. Yet it tops out at 50mph.
    If you don't need 50, you can reduce pinion tooth and gain low end, while also running a cooler motor/esc.

    Great advice. Just changed over to my 1st brushless system. Terrible motor stuttering... was about to return it as faulty. Re soldered bullet connectors and also battery connector, freed up wheels and now it's way improved! Does need a shove to get it going now and again but much better... Cheers, great advice!

      I'm glad the video helps! You can always try reducing the pinion count on the motor. This will unload the motor to help with the heavier T-Maxx.

    Hello I have a xstr 1/10 buggy (normal brushed motor) I have brought a new brushless combo which is 4370kv with a 60a esc both waterproof and can also take 2s or 3s Lipo. It keeps cogging every time I try let it off on ground, it starts to clog for a few seconds and THEN picks up speed. If you could please as to how I can solve this, also I’m using a 3s 11.1v 3s 2200mah overlander battery, am I using the wrong battery? I have also purchased a esc programmer for this combo just waiting on it. If you could help would be much appreciated thank you

    I have a GTB novak brushless sensored system in a Losi xxx-sct. I am having a weird issue. My Platinum Orion 2S 4800mah (I believe its a 25C pack but it does not say) pack works perfectly fine with the setup but my Zeee 2S 6200mah 60C battery has really bad stuttering when I take off at full throttle. I have two Zeee packs and they both do it. It does not happen when I ease into the throttle though. Any idea what could be causing this problem? I thought I might have gotten some bad battery packs a while ago or maybe the Novak GTB esc just does not like the higher C rating batteries? I was going to order some different brand packs with the higher C rating like the Zeee packs I have and see if the issue continues. If you have any ideas why this could be happening I am all ears. Thanks

    So I have a very weird issue. I have a 3674 2260kv running on a wp sc8 120amp with no issues at all. I recently put a 4076 in its place 2000kv and it cogs and cogs or if I hit full throttle and it's under load it cuts out and the esc goes red light and no throttle. It's in a rustler 4x4 so not much weight I'm running slightly higher gearing to accommodate the much lower kv. I noticed one motor wires feels slightly warm after 30 seconds of use as thats that's its current max run time? Is it possible the new motor is trash or bad solder job from factory? I'm only running 3s and max for the motor is 5s.

    Hello. Can you please explain - does minimum motor speed depend on KV? I mean, will a lower KV motor be able to rotate slower without cogging?

    • @RCexplained
      @RCexplained  Рік тому +1

      Not necessarily. It would be better to use a higher kv and gear it down significantly so that one rotation of the motor has the most minimal rotation at the wheels.

    Thanks for the videos. Between you and John Holmes I've learned alot about rc motors in the last couple months. I have a question about dielectric properties. There are lots of testimonials on UA-cam about the effectiveness of using corrosion x to make electronics more water resistant. Unfortunately we can't get it in Canadian stores. Fluid film looks promising but the two products use different units to describe their dielectric properties. Dielectric strength of 37kV for corrosion x and specific conductivity of 'less than 10 -9 ohms/cm @1 mHz' for fluid film. I haven't been able to find out how to convert one to the other for comparison. Any advice? Thanks again.

    • @RCexplained
      @RCexplained  4 роки тому

      Hi Beleg, thanks for the comment. I totally know what you mean by not having access to CorrosionX in Canada. Probably the reason I have never owned any. Have you looked at just ordering some online?
      I'm not sure you can compare these values based on the different methods of how they are determined and measured. It's breakdown voltage of the dielectric vs resistance of another product. It's unfortunate they only provide one value as a means of understanding its resistive property
      The specific conductivity for the Fluid Line product, typically measure in Siemens is expressed in 10 ^-9 ohms/cm. Siemens is also expressed as mho (ohm spelled backwards) Assuming this is what they mean, you can convert this to Specific resistivity, but relating it any further will be challenging. The best I can suggest is taking the Specific Conductivity Value and converting this to a Specific Resistivity.
      It may be more simple to buy a cheap ESC and operate it with the product testing its performance while introducing water. If you like the results, use the product. What do you think?

    • @beleg1437
      @beleg1437 4 роки тому

      Thanks for the reply. I was starting to wonder if that value was supposed to be exponential notation but they left out the ^ symbol. And I thought a product labeled as non conductive should have a hight ohm value and not a low one. Anyway, the math and physics involved is getting too complex for me so I'll take your advice and do some experimentation. Just upgraded 3 rtr rigs to brushless so I've got some electronics I can sacrifice.
      Thanks for your time.

      Yes, I looked at the specs of the firma motor vs velineon and on paper the 4000kv motor should also get your RC to stand up. The firma motor will draw more current upon acceleration, if your battery isn't up to the challenge you may not get the performance that you are expecting. IR of the battery comes from your charger. Does your charger support this feature? How old is the battery?
