Posted July 3, 201311 yr Hi guys! A year ago i built a sandrail... yesterday i felt like i wanted to build the MKII and so i did... Features: - 1 RC motor - RTC steering via M motor - Front independent suspensions - Rear live axle It's really simple, the concept was to use the less beams possible to keep it light... So i bult almost everything with axles and connectors...it weighs 412g and it's pretty fast. BUT there's a problem...as the RC motor is very powerful, in some overstress cirumstances, the little 12t gears tend to break...that's why i called it "The Gearsbreaker" well there's not too much to add to the pictures you can see ^^ tonight im gonna upload the video to show its performances Edited July 6, 201311 yr by piterx
July 3, 201311 yr Author oh yes it is :D except when one of the two gears breaks lol i made it just to have something to play with while im planning my next big model
July 3, 201311 yr AWESOME! I'm about to make a small RC rally car inspired by your little rally chassis and rm8's boss crawler! I'm using an XL motor for drive though, hopefully that won't break any gears! :P
July 3, 201311 yr I would expect the CV joint to go first I've had multiple models where the gray end expands from torque and becomes unusable, then again I was using two buggy motors
July 3, 201311 yr Good work! About gear braking, maybe use a 12 and 20 tooth gear combo? It will be slower, but less strain on the 12 tooth gear. P.S. where did you get the chrome pin joiners?
July 3, 201311 yr Author thanx guys :) I would expect the CV joint to go first I've had multiple models where the gray end expands from torque and becomes unusable, then again I was using two buggy motors yeah i was expecting that too...incredibly it's like brand new! Good work! About gear braking, maybe use a 12 and 20 tooth gear combo? It will be slower, but less strain on the 12 tooth gear. P.S. where did you get the chrome pin joiners? eh i couldn't change gears with the axle i made i got the chrome pin joiners on www.mangiobricks.it....they have lot of them but are quite expensive
July 3, 201311 yr in some overstress cirumstances, the little 16t gears tend to break These are 12t gears, not 16t gears, and as anyone can tell you, they are paper-thin. You could solve this using knob gears instead.
July 3, 201311 yr Author These are 12t gears, not 16t gears, and as anyone can tell you, they are paper-thin. You could solve this using knob gears instead. edited yeah i thought about using knob gears but i should have changed the rear axle to do it... not a problem anymore because it's been dismounted to build another similar redneck thing xD an italian redneck thing btw im editing the video, i'll upload it in a while
July 5, 201311 yr I would also suggest trying another type of linkage than those tiny little 12t gears. I have seen a design before that uses both a 12t and 20t bevel gears on the same axle, thus there are two sets of gears meshing each other at once. tim
July 6, 201311 yr Author i completely forgot to upload the video to youtube these days lol! here it is! i had some things to do so i did a fast editing...
July 6, 201311 yr YEAH! omg that poor camera!! Great drive, with awesome skids! Nice video showcasing your model. It sure looks light and fast. Great job as always. :thumbup:
