Rehab1 Posted August 11, 2017 Share Posted August 11, 2017 I went back to the automotive proving grounds today and spent 2 1/2 hours setting up drones and cameras while riding up and down their 20% grade hill. I took along the whole family of wheels that included the Gotway ACM 1600, KingSong 16S, Inmotion V8, Inmotion V5F+ and my little 10" Gotway Luffy. I have never went down the 20 % grade, only up it a few weeks back, so I was a bit nervous at first but after practicing dozens of times on the ACM 1600 earlier in the day it became natural. I was able to transverse both the 20 % and 30% grades with the ACM that allowed me to gather temperature data that I will share later. The ACM 1600 did outperform the other wheels ( including Luffy ) but that was to be expected given the excellent torque and power the ACM possesses. I apologize for the background noise during the first few minutes as they were cutting grass on the complex. Link to comment Share on other sites More sharing options...
WARPed1701D Posted August 12, 2017 Share Posted August 12, 2017 Awesome video. Nice job. Based on your closing comments I get the impression you were you disappointed with the 16S performance. Am I misinterpreting your tone/wording? Link to comment Share on other sites More sharing options...

No I really do like the KS16S but was hoping it had a bit more torque. That's ok as I will not be climbing hills of that size grade very often.

Marty Backe Posted August 12, 2017 Share Posted August 12, 2017 Looking forward to seeing any ACM temp data that you got. With those hills you should have been able to really drive the temperature up high. BTW, am I correct in surmising that you like to run your wheels on the lower pressure end? At least that's how it looks from the video. I'm not judging, just curious Link to comment Share on other sites More sharing options...

What probe do you think topped out....motor wires coming out of the axle or the bullet connector? I just finished the other video and the graph. The 30% hill grade was a bear. 16 minutes ago, Marty Backe said: BTW, am I correct in surmising that you like to run your wheels on the lower pressure end?

A few wheels might have been low. What psi do you average? I'm sticking with my original prediction - that the wires would be hotter near the connectors than what's coming out of the axle. When I fill my tires I top them up to the max specified on the side of the tire. 45psi for the ACM and MSuper, 65psi for the KS14C. This is a very personal choice due to how it affects the ride.

This is a very personal choice due to how it affects the ride. I purchase one of those nice little electric pumps with a digital gauge that a member commented on earlier. I filled the tires a few weeks ago but I should have checked the pressure today. Link to comment Share on other sites More sharing options...

meepmeepmayer Posted August 12, 2017 Share Posted August 12, 2017 Wonderful! That was a lot of effort, especially the filming (attempts - bad drone!). Link to comment Share on other sites More sharing options...

The ACM is the only 84v wheel. All of the others are 64v. Here is a little chart I threw together. Link to comment Share on other sites More sharing options...

Actually the filming was not that bad. Yes It would be easier to have a second person but the tripod worked out great even with the slight wind sway. I just left the camera on the top of the hill until I was done filming. The drone just kept loosing me. It did not like me turning around. It was able to follow me easily on the oval track a few weeks back. Link to comment Share on other sites More sharing options...

The V8 is 84v. 99% sure the V5f+ is too. Edit: confirmed V5f is 84v on ewheels.com Link to comment Share on other sites More sharing options...
