piterx Posted March 14, 2013 Posted March 14, 2013 i bet this is going to be really fast :D i already love it ! Quote
z3_2drive Posted March 14, 2013 Author Posted March 14, 2013 (edited) How do you plan to do the drive shafts? edit: Oh I see, the telescoping universal joint in there. Using universal joints on these cars always seems like the weakest part. I think if i was building a rock crawler, or high powered car, i would try to use the yellow 4 tooth gear. uhhh....what are you on about? the driveshaft comes straight out of the motors, then into a 20t gear that drives the differential. Out of the differential comes a pair of these--connected by a pair of these--(they touch so they dont move along the shaft) and the second light grey piece connects into this hub(which has yet to arrive)- So-no u-joints here and should be very strong, but plastic wear is expected from non-greased pieces moving at high speed and using those yellow knob wheels drastically reduces performance of a high speed vehicle-they're only used for trial trucks/crawlers. 2 extra 20t gears are hopefully going to keep the differential in place and free of skipping teeth edit: I think you're confusing U-joints with CV joints Edited March 14, 2013 by z3_2drive Quote
z3_2drive Posted March 30, 2013 Author Posted March 30, 2013 well its been a VERY long time and long story short: It wasnt what I wanted so I went through countless mini models and ideas till I had another go...and guess what? Third time's a charm! it is VERY fast-key is DIRECT DRIVE, no gears whatsoever. It drifts, it spins, it handles great! the front steering has a caster angle which helps the return-to-center steering. Video will come another day but for now pics(I threw the model together as quickly as i could ) ^rear axle was tricky to build around motors, but new hubs helped a lot ^interesting battery placement makes the center of gravity low and in the middle of the car. Hope you like it! Quote
jorgeopesi Posted March 30, 2013 Posted March 30, 2013 Nice, the angle helps the engine and improves maneuverability. I already use it in my Huayra but it was very slow to see its performance but I parked easly . Quote
750ACE Posted March 30, 2013 Posted March 30, 2013 Nice, but do you have a video? He said another day in the post today. Quote

tibivi Posted March 30, 2013 Posted March 30, 2013 That is a nice rc chassis, good work Now designing a body for it. I look forward to see the video Tibivi Quote
Sicil Posted March 30, 2013 Posted March 30, 2013 Looks cool. I hope the chassis will get a beautiful body. Quote
timslegos Posted March 30, 2013 Posted March 30, 2013 Looks fast, how did you create the caster angle? tim Quote
