Additionally, in order to make the batteries last 5+ minutes, it was necessary to let the car roll through the corners power off, then pick the throttle up gently on the exit so as not to take too much out of the cells. Ah, the joys of racing with 1700mAh cells...  |
i guess so, but the rc10 at the time did have a working and better slipper clutch didnt it? even back then, compared to the zx-r, the mid wasnt as easy to drive, simply becuase the lazer had a better and more consistent slipper. i just tested the car an hour ago and i am very glad to inform that the slipper works VERY well. The setting is consistent until the battery is out, and never once did the pad or spur burn out like it did when i tried to let the original OT-88 slip a lot. The car was VERY much easier to drive. setting a slipper is a compromise between the high traction and low traction conditions, so i set the slipper for the high traction area of the track, otherwise the car will not have enough speed to clear the jumps. but at the low traction loose sand area, i had to feather the trottle to prevent wheelspin. The car is so much more easier to drive. In the high traction section i stab the throttle in the corners and yet there is no wheelspin at all! i also took huge jumps many many times and the slipper "slipped" and protected the internal gears. I did install pargu2000s aluminium center gear with new OT-86 counter gear and new SG-25 sprocket, and the car is super smooth. Hard landings were quiet too, testament of the protection it provided the internal gears. i am glad to say i am ready to mass produce this shaft, with minor tweaks to make it better. Video is coming soon. Merry christmas and Happy New Year to everyone!
