2018/5/26

OpenRC Truggy the first 3D print RC Car, I noticed that project on thingiverse.com after few month i got my I3 3D printer.  the OpenRC truugy is a fancy project, so many people like it. RC is always attractive to me, i decided to got that built-ed.

this is a hard to RC world actually.

while everything come to together,  it's magic moment.

then I dive into RC car, never came out again. I printed with PLA which is definitely not recommended.  but, so what.

ooh, experience repairing car every one or several minutes  playing is awesome for fist several days. then you will headache,  there is no time to enjoy drive, everything you do is repairing. anyway, at that moment, exciting exceed everything other.

PLA ties is really not a good choice, soft filaments is expensive than buy ties directly. so, I got this.

Most hard problem is the dog-bone cup broken. even tough i make lots of improvements, it still broken anytime. 

lately i found the 550 brushed motor is so hot, i burned several motor for that reason. i decide to add a gearbox for the RC car. and this is what i got.

i modified the design and make it compatible to my own gear box.

It's pretty strong, yes, it's metal,  driving is so happy. and guess what, like every rc fan, i starting to wonder if the 3D print RC car cloud be more

 strong and more violent?  after all for now, I got only 15km/h speed which is pretty slow than a normal RC car.
