I love my old vattera acceder k10. The extreme torque twist is part of the fun of owning it. With only a team spec 2250kv v2, a sw4 an shv500v2 servo it keeps up with most new rigs. Even running the stock tires yet. Lol please do more this type videos.
Could you talk about timing in brushless motors and escs? Like how it works and effects performance, efficiency. Thanks for all the info on rcc as well
This is why worm gear differentials are so effective on small RCs. If they made a 2 flute worm gear you could get a tremendous reduction in the axle. I would like a military style axle with a worm drive and a combination gear driving the differential gear. Like having a little gear box on the axle.
If I can, I always try to put under drive into the rear axle on my rigs. Looks like I've been doing it right all along. :) Thanks John for the informative content .
thank you for the great and informative answer! i understood everything, so, as far as i'm concerned, you explained it nicely! :) and it's a he! :D and i guess the ancient romans wouldn't be mad at the pronunciation :D :D
When it comes to the micro world I guess you would call it micro write 24 scale there's a certain company that makes an axle just like that it's warm gear driven and portals amazing stuff treal hobby
To avoid torque twist there's nothing better than worm drives. Easily 25:1 ratio in one compact step from drive shaft to wheel axle. My Losi Comp Crawler, a pre 2010 design with worm drives, has never shown any sort of tendency for torque twist. Add 2:1 portals and you'll need less than 1.5:1 at the motor. The downside with worm drives is that they're inefficient and thus require more motor power, lubrication and cooling.
I have a question regarding overdrive. I've been recently going through a series of videos regarding this matter, and found out that it is not so beneficial as people say, Could you clarify this topic more (I know that it benefits narrower steering angle, but looks like front spinning wheels loose traction a lot)?
My own experience is that having some (10-20%) difference in wheel speed is just about always beneficial, not only in steering but also in negotiating steps where the front wheels need to move vertically while the rears go horizontally. Another more physical benefit was that the front worm drive got a lot less load with overdrive, so it doesn't get nearly as hot as it did with both axles at same speed. That said, there's most probably some upper limit where it becomes too much difference.
👍 Great info. I have very good results with underdrive in the real axle AR44's straight axles on SCX10ii. On my SCX10iii Basecamp portal i don't have the same results doing the same underdrive in rear, any ideas why ? Thanks in advance.

There are only a few crawler channels on this platform worth watching every single time. This is one of them.

Always informative! 👍
I gear down my axles as much as possible.
I knew you couldn't resist thank you brother

Maaaaaaan, great question and topic itself 🤩🤩 thanks for answer 👍💥👏

It's always an interesting video. I constantly try to take what I learn and apply it to what I'm doing
Glad you enjoy it!
Speaking of link geometry and how it relates to torque twist and gear reduction in the axle, I would love to see a video about suspension geometry!
Great suggestion!
👋😎👍

@@ollep9142 indeed, worms are great if we ignore the efficiency hit.
Is there an ideal percentage of over/under drive? Does it start hindering performance if too much wheel spin?

@KRXLlON ahhh, that's a good topic and actually quite deep!

You want it regardless what some videos may say. Makes the rig perform completely different.

@@chertrocktunnelgarage2171 they used the same 4 link geometry for both axle types. That doesn't come without consequence.
when does torque start dropping out in kv wise with rock crawlers, where's the band that torque isn't there as such any more and its about rotation
@@theweldingone ive found 2700kv to be max that is fast but still crawls well. Above that, the esc can get unhappy unless it's huge.
Question, how did you develop that sultry voice?
