peej410 Posted April 2, 2006 Share Posted April 2, 2006 here are videos of my RC rock crawler. they are both the same video just in different formats. http://www.autosportfab.com/movies/PetesRC.mp4 http://www.autosportfab.com/movies/PetesRC3.mov http://www.autosportfab.com/rccrawler/ and heres pics of my crawler now heres where i need hybridz help. the steering servos everyone uses are either weak or expensive (100 each for good ones) i was thinking of building small linear actuators, does anyone on here have experience with linear actuators who can give me some advice? i can have parts CNC milled but i was hoping someone could shed some light on wether or not they would actually be better before i even start drawing some schematics... thanks in advance!

Z-TARD Posted April 2, 2006 Share Posted April 2, 2006 Wow, thats pretty cool. The articulation on that is unreal. Have you looked at sail winch servos? I seem to remember some of the Hi-Tech and Futaba servos being pretty cheap, gobs of torque too. Mike Quote Link to comment Share on other sites More sharing options...

Z-TARD Posted April 2, 2006 Share Posted April 2, 2006 How much torque are you looking for? I was thinking more along the lines of this one: http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXN668&P=7 Quote Link to comment Share on other sites More sharing options...
Guest TegRacer324 Posted April 2, 2006 Share Posted April 2, 2006 That's sweet. Too bad I haven't fired up my car in like 2 years. Yeah servos are quite pricey for good ones. I know the tail rotor and wash plate on my heli were like 100+ a piece. That would be cool to make your own. Quote Link to comment Share on other sites More sharing options...

SuperKid Posted April 2, 2006 Share Posted April 2, 2006 That's awesome! Great choice of music for the video too! I was actually listening to that song before I played the video. Quote Link to comment Share on other sites More sharing options...
