High Altitude 2.2 Shepard comp rig Time for a build thread. This is the second Shepard I've built, I sold my first one at the beginning of the year after I bought a new house. Current specs are stock axles, links and 4wd locked capra trans. Futaba S9177 servo, HH BRXL and a Team Br00d 30t brushed motor for the time being. https://live.staticflickr.com/65535/...5ec743de_c.jpg2020-08-04 07.49.51 by Casey Childs, on Flickr https://live.staticflickr.com/65535/...dda1e853_c.jpg2020-08-04 07.50.02 by Casey Childs, on Flickr https://live.staticflickr.com/65535/...0334cc0a_c.jpg2020-08-04 07.50.12 by Casey Childs, on Flickr https://live.staticflickr.com/65535/...947ace74_c.jpg2020-08-04 07.50.37 by Casey Childs, on Flickr Proline IBEX 2.2 tires with CI 5.5 dual stage foams wrapped around High Altitude P35 carbon wheels. The fronts are on 475 SLW hubs to clear the brass knuckle weights and the rears are 225 hubs with the face tucked back for a deep dish look. https://live.staticflickr.com/65535/...4fde74c0_c.jpg2020-08-04 07.51.07 by Casey Childs, on Flickr https://live.staticflickr.com/65535/...c5cd00e6_c.jpg2020-08-04 07.51.18 by Casey Childs, on Flickr Prototype brass portal covers with room for 3/8" tungsten slugs. Fully loaded they add 7oz per side. https://live.staticflickr.com/65535/...af21729c_c.jpg2020-08-03 22.29.47 by Casey Childs, on Flickr https://live.staticflickr.com/65535/...9c085ea2_c.jpg2020-08-03 18.54.22 by Casey Childs, on Flickr Currently its sitting at 4lbs 3oz RTR with no added weight, should be around 4lb 14oz with knuckle weights and a painted body. Going to throw some paint at it and get it wired up this week so I can get it out on the rocks this weekend. Its been too long since i've had a super capable 2.2 shafty rig to play with. |

Re: High Altitude 2.2 Shepard comp rig Cool rig! Boy Losi sure didn’t do any favors to the beauty off those bodies with their new light bar mount did they? |

Re: High Altitude 2.2 Shepard comp rig Realized I couldn't find the window masks for the Night Crawler body, so highlighter yellow spray bomb it is. https://live.staticflickr.com/65535/...08c5916f_c.jpg2020-08-09 12.52.30 by Casey Childs, on Flickr https://live.staticflickr.com/65535/...f59f3311_c.jpg2020-08-09 12.52.41 by Casey Childs, on Flickr As promised, here's a couple videos of the car's first run. I have more videos on the Go Pro, but haven't downloaded them yet. https://live.staticflickr.com/31337/...52efb17c_c.jpg2020-08-09 12.48.06 by Casey Childs, on Flickr https://live.staticflickr.com/31337/...2627de83_c.jpg2020-08-09 12.48.27 by Casey Childs, on Flickr https://live.staticflickr.com/31337/...63625884_c.jpg2020-08-09 12.52.18 by Casey Childs, on Flickr Overall I'm very happy with the car to start with, its smooth and predictable and the IBEX are shaping up to be a killer tire even in 100* weather. The only things that really need to change at the moment are 350 hubs in the rear to get the rear width closer to the front width and possibly a 10t pinion to get a little more low end control. The car has plenty of wheelspeed, so gearing down a little will help motor temps and battery life. |

Re: High Altitude 2.2 Shepard comp rig Been driving this rig and getting more used to how it reacts and can start to figure out which direction I want to go next. Big one on the list is more reduction and cutting some weight. i ordered some grade 5 titanium rod last week for links, and started working on a new skid and trans set up. https://live.staticflickr.com/65535/...44000863_c.jpgScreenshot 2020-08-29 16.18.56 by Casey Childs, on Flickr https://live.staticflickr.com/65535/...2bb962cb_c.jpgScreenshot 2020-08-29 16.19.04 by Casey Childs, on Flickr https://live.staticflickr.com/65535/...09f87789_c.jpgScreenshot 2020-08-29 16.19.09 by Casey Childs, on Flickr Based on XR gears with a slight forward motor design. Will be capable of 9:1 to 4.5:1 overall reduction. Finalizing the gear spacing and layout before I commit to designing the case and sending everything to Shapeways. |
Re: High Altitude 2.2 Shepard comp rig Nice build as usual for you Casey. Thank you for using Crawler Innovations Double Deuce foams. |
Re: High Altitude 2.2 Shepard comp rig That is a great looking and performing rig. I went with a sporty chassis on my capra also. Trying to really get it dialed in. I am itching to pull the trigger on those 2.2 ibex tires. How much of an improvement can I expect going from a 1.9 tire to a 2.2? Also do you have the tie rod bent and steering stops shaved down? What would I accomplish by moving the upper links to the highest of the 3 holes on the skid? The truck already drives good but I'm looking to just take it to that next level. I think I had my shocks a little to laid out so I moved them up a hole. Any tips are appreciated Thanks <a data-flickr-embed="true" href="https://www.flickr.com/photos/190436976@N02/50404272733/in/dateposted-public/" title="120244738_10164310967040716_718401594564703 5079_o"><img src="https://live.staticflickr.com/65535/50404272733_0d61fc679f_b.jpg" width="1024" height="768" alt="120244738_10164310967040716_71840159456470350 79_o"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script> <a data-flickr-embed="true" href="https://www.flickr.com/photos/190436976@N02/50404980386/in/dateposted-public/" title="120276578_10164310967095716_689320226194752 2439_o"><img src="https://live.staticflickr.com/65535/50404980386_7ab8e37bf6_b.jpg" width="1024" height="768" alt="120276578_10164310967095716_68932022619475224 39_o"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script> |
Re: High Altitude 2.2 Shepard comp rig Quote:
The steering stops are completely shaved off, and the tie rod is bent to clear the diff with 60*+ of steering angle. Moving the uppers up in the front makes the front dive under power which helps keep the front axle down on obstacles. Its not a universal thing though, your COG is different and you will see different affects from link geo changes. |

Good info thank you. What is the advantage to running the slw hubs? Is this mainly to offset the wheels to clear the weighted knuckles, or do they serve another purpose? TIA |
Re: High Altitude 2.2 Shepard comp rig Awesome looking rig!"thumbsup" |
Re: High Altitude 2.2 Shepard comp rig How’s the transmission coming along? |

Re: High Altitude 2.2 Shepard comp rig Question, where is a good place source the 2.2 lightweight comp style wheels without breaking the bank? Anything out there? Having trouble finding something. Ordered some 2.2 wheels off amazon and they are heavy as shit, definitely not what I was looking for. |
