Eman Posted August 2, 2016 Share Posted August 2, 2016 Hi Guys, please no comments "why" I'm thinking about making my KS-16 faster and please no comments about "Did you read the Topics about 'falling off at more than 30 km/h..." I was thinking about the following when I downgraded my KS-16 from Firmware 1.20 to 1.18: Due to the downgrade procedure I downloaded a wrong 16B.bin file from this forum which almost bricks my wheel. BUT, I had still the possibility to get my wheel to work again. When I went to the downgrading page at my app, it let me select the firmware for "every" Kingsong model. I needed to select manually which one fits. Of course I choose the KS-16-B which is my model. But I was thinking about: "What would happen If I would install the Firmware for the KS-18AZ+"? I assume, the A, A+, AZ+... stands just for the Battery version and maks the correct calculation for the "still possible ride-able kilometers. As The KS 18 comes as well with 680 WH, the KS-18AZ+ Firmware could fit perfect. Furthermore I did the following calculation: At 30 km/h we drive 8,333 m/s. The Tire on the KS-16-B has the following size: 57-305 what makes a length of 1316 mm. That means, at 30 km/h the wheel is turning with 6,33 rps. If I assume now the Tire-Size on the KS-18 with 57-355 the length is 1473 mm. At a speed of 40 km/h, we drive 11,111 m/s. that means 7,54 rps. If I calculate that down to the KS-16, it would mean, with 1316 mm length, 7,54 rps results in 9,93 m/s what means 35,7 km/h. => If the Firmware 1.18 from KS-18 is running on the KS-16, it means that at a speed setting till 40 km/h, the wheel drives 35 km/h. Many times I pushed the tilt back more after coming up and 35 is really no problem for the motor. For long distances maybe yes. But the 35 for me is just needed to catch sometimes the faster bicycle-drivers. Haha. Questions: 1. Can someone with a KS-18 please post the exact wheel size? It's written on the size of the wheel... 2. Can someone post the Firmware 1.18 for the KS-18 with a 680 WH-Version??? Meanings? No advices about the security if it has nothing to do with bricking the wheel... Emanuel Link to comment Share on other sites More sharing options...
US69 Posted August 2, 2016 Share Posted August 2, 2016 i think ( and hope) that this will not work...if i am allowed to say that :-) As the KS18 working with a different wheel size, the hull sensors and/or gyro will be controlled differently also... Even installing the prototyp version of the KS16 (16a) makes the Ks16 go crazy...so i assume that it will be the same with another wheel firmware.... but keep us informed...

flass Posted August 2, 2016 Share Posted August 2, 2016 Maybe I have dreamt this but: Wasn't the speed limit 40 km/h on KS-16 in the beginning when it was new on market, and then later it got restricted to 30 km/h? Link to comment Share on other sites More sharing options...
JumpMaster Posted August 2, 2016 Share Posted August 2, 2016 What limits the speed of the wheel isn't how fast it can spin but how much torque it has at a given speed. The faster you go on a wheel the more likely it is to fail at keeping you upright. Especially if you're going up a hill. I wouldn't recommend pushing the KS16 beyond 30kph unless you're wearing full body protection and are ready to take a fall. Link to comment Share on other sites More sharing options...

Nope! Must have been a dream.... Link to comment Share on other sites More sharing options...
OliverH Posted August 2, 2016 Share Posted August 2, 2016 Ks16 has a fan, KS18 not. Motorparameters should be different speed calculation should be different because of wheel size if we look on @esaj experience with his mock up for the Firewheel part the position (height) of the gyro needs to been calibrated in the firmware. Flashing the wrong firmware could brick it. Wondering if there's no chech. @tinawong ? Link to comment Share on other sites More sharing options...
