  1. Okay, I had a quick idea that has not been completely thought out. So excuse the brevity and the stupidity if present. The dreaded CV joint. The haunted U joint. I had an off kilter idea I have yet to try out and didn't want to forget. I'm a loooooong time lurker here and almost forgot I had an account. Here's my solution. Has anyone here tried heat-shrinking the joints? If using a malleable type of shrink, it should still allow movement, no? And if this is not practical in theory, what about heat shrinking to the wheel hub? Maybe this is too quick of a thought but maybe would be valuable to others or possible spark investigation.
  2. IMG_0560 by JJ2Sam, on Flickr Hello, Here is my new MOC I named "No limits", It features Traxxas Titan 380 motor Tenergo 5000Mah 7.2V battery HobbyWing Quicrun ESC Futaba Standard Servo motor Custom CNC milled aluminum parts by Brick Machine Shope 3D printed 4bevel gear differential by kind Efferman :) FlySky remote + receiver When I first build this it had full independent suspension but it was melting the CVjoints and UJ's I was using so I settled with a pendular rear suspension for rigidity and a single spring independent suspension for the front. Overall the suspension works well on pavement as well as on loose dirt or gravel terrain. Effermans custom differential works very well and has never ground gears even after my brutal driving and the high RPM's it is spinning at. IMG_0557 by JJ2Sam, on Flickr IMG_0555 by JJ2Sam, on Flickr The single spring front suspension really helps the performance because it basically allows one wheel to go up and the other down in the same motion much like a bogie but still allows up and down movement. One thing I am not happy about it is the HORRIBLE geometry since the top beams are monger then the bottom ones making it have a negative camber angle. The pendular rear suspension was the only choice since I dont have Effermans custom CV joint parts that would allow full independent suspension with drive. IMG_0558 by JJ2Sam, on Flickr IMG_0559 by JJ2Sam, on Flickr I mounted the ESC and receiver up high to allow air flow to cool the parts and have easy access to them. The battery was mounted very low with only 2 plates protecting it from the ground kept the SOG really low so I could do full-throttle 90 degree turns without flipping over. Overall it performs VERY well and has not flipped over ever and has broken the Lego speed record by doing 32kph IMG_0586 by JJ2Sam, on Flickr Hope you enjoy and please leave a vote on the poll on how you like the use of custom electronic parts.
  3. Friends, It took a little too long, much like the ATS, but the MD600N if finally done. Much more at, and the Flickr album can be found here. As I child I would see the MD600N and MD520N flying up and around my house. It was time to honor the love for the aircraft. The MOC has the following features: Opening Doors Working dual Joysticks Working dual Foot Pedals Working collective lever Swashplate Collective control (much thanks to Efferman for many components of the design) Swashplate Cyclic control NOTAR rotation Six bladed rotor PF L drive with LiPo Battery Working Landing skids (I mention this only because getting it to support the MOC and not tip over was quite a task) Seating for eight I hope you all enjoy.
