ive never been a fan of axial rod ends. come to think about it ive never been a fan of any manufacturer's rod ends except for traxxas |
The Mantis does use Revo rod ends. Speaking of which, the Mantis and the Dub cab for it are now available for purchase here http://stores.intuitwebsites.com/Bil...Categories.bok They will begin shipping this Wednesday - 8-10-2011. Here's a sample video of the Mantis in action. :mrgreen: http://www.youtube.com/watch?v=fMUw8wHOQ0w BW |
Wow! That is impressive! I can't wait for mine to get here! |
Agreed ^ WOW! I love the innovation and great performance while keeping those sexy sleek lines. It's like the best of both worlds. This is one great looking chassis with a lot of wow factor. Really great job! |

but may i know wat are the advantages of this unique design over the more conventional(as in havin 4 shocks) design? a more weighted front compared to the rear? thanx |
I presume it's 2.2pro legal with body panels? Could body panels just be large pieces of clear packing tape? I think they have to be attached representative of automotive use...Corvettes are bonded together plastic. |
just put in my order for the chassis and topper "thumbsup" hopefully i'll be able to begin building this weekend:mrgreen: |
very cool video that thing can crawl!"thumbsup" |
It's beautiful! But still is it usable? I wanna see it split by the rear link, with a pivot and a mono-shock installed on the rear. Lower and mid part in cf, top in Acetal/ Delrin. But beautiful design "thumbsup" |
Ordered it today! Thanks Don! |
Thanks guys, I can't wait to see some of your builds! I love this thing so much that it is going to be my comp rig for this upcoming season without question! Quote:

I've thought through a dual or mono shock version of this kit but it would take away from the simplicity of it and the ease of setup...not to mention the fact that this design performs & flat out sticks to the rocks, and is very low maintenance & durable. "thumbsup" BW |
So are there any plans for a CF one? :P that would be sweet! |

As we speak, I'm out in the garage reworking my wiring to be ready for an already ordered package."thumbsup" |
I think some of you aren't realizing there's some torsion action happening there. Carbon Fiber would eliminate that. |

Quick story to expand further on that: I ran one of Don's Axial torsional chassis called the SSS, before the SSS-R. I had it set up super light (lighter than Don's! :flipoff:) and it didn't flex much at all, but I knew the limits and how to drive it. Occasionally I would let a few others try (operative word) to drive it and after a short while they'd all say the same thing, "How in the hell do you drive this thing!?" They didn't know the limits, and it wasn't to their style of driving. They wanted big amounts of flex, and I didn't. That is my style. |

Years ago I locked out the rear suspension on my TXT. Granted it managed to climb steps it couldn't ever before, it was (kinda) crap everywhere else. There was a train of thought that with the rear locked out that it would transfer all the weight to the front, hence being able to climb the steps it never could before. Which is great and all, but who builds crawlers to only climb steps? With the rear end moving around at least a little bit, you've taken the one trick pony and allowed it to do better at other moves. I'm guessing rear foam tuning will be a little more important than usual. |

Here's one driving difference noticed during our video time...the off camber transition to side hill climb starting at 2:17 in the video. Note that the rear axle stays planted through the entire sidehill portion, from entry to exit. The Mantis took this line easily first try, by all three drivers (2 of whom had never driven this rig at all). The other two rigs there were both able to pull the same line after a few tries, but the inside rear was floating on both of them...more on one than the other. Another difference would be how you approach a high break over. If you don't have the belly clearance for it, you may take a slightly angled approach to make sure you can get over it. This can become a problem if you have a technical section immediately after the break...where a high break over chassis will let you choose what angle you want to approach from...as it will clear regardless. Something else we noticed was on descending a steep incline following a break over. The Mantis stayed planted and could descend at normal speed, slow, or dragging the rear axle. The 4 linked rig that tried this needed throttle immediately after the break in order to not flip on its lid upon descent. Again, if you don't have as much tendancy to flip while descending, you can focus more on what's next on course as opposed to fighting to keep your rig rubber side down. EeePee's flexy/no flexy comment is valid but being that flex is tunable on this chassis, it's not much of an issue...unless you plan to run it at sub 4lbs...then she'll be a bit stiff. :mrgreen: The major 3 wheeling point on the vid starts at 3:53, and that is due to my running lighter delrin wheels and I had one of the braces installed on the tail section for descreased flex (whereas the part leading up to 3:53 I had both tail braces out for max flex...given my still light weight wheels at 3 ounces each with rings and hardware). From the portion of the vid prior to 3:53, to 3:53 forward, you can notice a substantial difference in flex on every approach and that decreased flex from the back half of the video does take some getting used to, if you are used to flexy setups. I run rigs both ways so it's a non-issue to me. CF doesn't react the way delrin does, and machining out enough to have at least the needed flex will leave it too brittle "thumbsup" |
I agree, for some time now I have run Carbon fiber and though it does have its uses in RC. Its meant as a stiffining product mainly for higher speed vehicles. The flex is just not there. Honestly, if this Performs as well as the SSS did. I will be very happy to run this rig as my re entry into comp crawling again. this was all the motivation I needed to getting back into it and buying an XR. I am very much looking to get this chassis and put my .12 cents into it. Don, what would you say is a good running weight? did you try different weights and metal wheels when testing it to see what the differances were? |
I'm sitting here with a cf battery tray for a T-Rex 450se v2. AND must say this cf piece has tons of flex. (only 1mm / 3/64" thick) tho. Tho i agree on the use for it on this chassis w/o the modification i mentioned above w a sliced chassis and a mono shock, - can be a bad idea. (lol forgot this part, I must be tired). :) |
