Some parts I made for my lowboy. It is surprising how many downloads this project is getting. The aren't many quads around so people must be using the parts for something else. Things http://www.thingiverse.com/thing:286361 http://www.thingiverse.com/thing:283818 http://www.thingiverse.com/thing:345156 http://www.thingiverse.com/thing:283821 http://www.thingiverse.com/thing:180997 are also for the quad. I'm building a quad PPG wihich is powered by a verner JCV-360 engine -AKA hellcat-360 It is fuel injected. The enigine is monitored by a PPG-meter. I'm mounted the meter on the front right riser tube, I'm working on combining this with a phone holder. The battery charging etc is controlled by a device marked "Fly Henry". There is also an engine control unit. I've mounted these back to back on a vertical tube behind the seat. There is a 24V ni-cad pack for starting the engine etc. I've mounted this on the rear right main frame riser tube. This is a vertical tube - the photo is showing up rotated ATM. I wanted to run the 9mm plastic fuel line along a 20mm steel tube. Simply clamping it with zip-ties crushes the fuel line. I made a little clip which does the job without the crushing. A zip-tie goes around the clip to hold it in place. Later - made one for 26mm frame as well. I use this for radiator overflow and fuel tank breather lines. I made a clamp to attach the fuel pump to a 26mm tube. This works OK but could be improved by having a narrow bit at the bottom to prevent the pump sliding down. I will do a new version if this is a real problem. I'm moving the pump onto a 29mm horizonatal tube. For this I've made fuelpumpclamp-29. It is half the height and I'll use two of them. The tbarbholder is for mounting a fuel line T-peice on a 20mm tube. The oval holes are to hold a pair of zip-ties in place. XT60 - Oct 2014 The quad's existing battery is totally inadequate for cold starts. It can't supply enough power to crank plus run the fuel pump etc. So I've added a socket to plug in a SLA pack for starting. I'm only feeding in 24V not the 12V centre tap. I used xt60 connectors because they are cheap and have a high current rating (about 85A). The socket on the quad is glued into a holder which is zip tied to a 25mm tube. The other xt60 parts are for the battery, charging lead and blank plug to keep dust etc out of the used sockets. I tried including a cheap DVM into the charging socket but it failed - maybe another time. More info about my quad can be found here - http://eddiem.com/tikiwiki/tiki-index.php?page=Blackhawk+tandem+quad All parts were printed in PLA with .4mm slices. Holes for nuts are undersized to hold the nuts captive. I had to heat some of the bits to get the nuts in. The screws clamping the parts around the tubes are M3. I may have to redo the designs to use nylocks. The mounts screws for the flyhenry and ECU are M5
