hoping for better weather for next run of my IC car, and will try to video it . I’d like to see it run at 40 to50 mph, the RC car gearing is likely to be a significant factor in top speed
Thanks @WickedFog i was going to do a build a car from scratch but I was persuaded to make use of the marauder parts, the base needed to be upgraded so I used a fairly thick plate of aluminium (I am assured that weight isn’t critical For tethered cars!) I have already been told off by my...
Many thanks @Greywolf74 i have watched a video demonstrating the differences and I can see why scale truck models would benefit. Certainly better control at start up and when running at low speed
I have found a bunch of motor ESC combos, just one thing, they all seem to be sensor less, is this likely to be an issue?
I have tried to read up on the pros and cons of sensored motors and it seems that the three key reasons why sensored motors are favored is
Slightly better starting torque...
Thank you for your kind words @Lukedavis, I was more or less gifted the Mardave Maruder for its parts so I felt I had to make use of it, the next one, well that needs to be purpose built!
Sure, I posted a pic here:
this chassis is based on parts from a recycled Mardave Marurder, it is not typical of tethered cars from the 40’s & 50’s as the Mardave parts drive the layout.

This is true @Greywolf74 and i agree, the risks are not insignificant. The plan is to run it up steadily and iron out the behavior of the chassis by adjusting the spring rates and dampers. The car will have double tethers and the track is fenced off. I agree the Lipo does add a risk if it rolls...
Hello again, sorry to raise this again, but doubts remain in my head about my plan to go with a 'Low rev' motor solution in my car.
Despite visiting my local model shop for a chat and reading around the topic a little I remain concerned that a 1400KV motor driving through a 1:1 gear box on to...
I can see the appeal, you can focus on just one easily measured thing, mph!
Bit like free flight airplanes, I have always pulled my friend's leg about launching his beautifully built, uncontrolled, high performance airplanes and being surprised when it flies off and he loses it! :0)
Thank you, I was going ask about 'sensored' and 'non-sensored' motors, from what I read sensored improves control.
Actually we are allowed to push start IC cars so I guess a little assistance to get an electric car would be Ok too!
I can see that i am going to have to do some calculations...
Thank you @tudordewolf for your thoughts, and in particular the link to the speed calculator its a bit slicker than my spread sheet efforts.
I may have found a reasonably sturdy looking 1:1 rear axle/gearbox, just add wheels and motor coupling, but to get to my target speed that would leave me...
I have a slightly unusual requirement, I would like to build an electric tethered car, the issue Is, there isn’t much of a precedent set, and those that have built them seem to be aiming for speeds much higher than I can safely run. I.e. 200 mph. 100mph is fast enough for me.
the car doesn’t...
