|  Torque Twist / Lifting Issues... I've noticed a tendency to carry the front wheels while climbing. i.e - As you approach an obstacle from the left moving to the right, the left front tire makes contact first, as you climb up, the right front tire will lift as well. This occurs when on the throttle. As soon as you let off forward throttle, the suspension settles and the right tire drops. If you reverse the scenario, the problem is the same - carries left tire. Hopefully I explained that... lol Its kind of like some weird reverse torque twist. Dunno. Just wanted to see if anyone else noticed this? Specs- Chino chassis, losi aluminum shocks (limited 1/8 internal, 1/8 external, 50wt 3 hole front, 60wt 3 hole rear, Blue springs except left rear, black) Blue claws, Axial 1.9 BL with 6oz each. Weight biased front, 645mg, 2s 800 lipo on the links. tia-  |

| Did you flip your tranny around yet  If not just undo your skid plate with the tranny still attached and flip it around and mount it back up. You might have to do a little adjustment or not, depending on where you have your links and electronics. That should help with some of the torque twist. |

| it is a squat/anti-squat (too much in either direction will cause that problem) issue that is causing the truck to do that. play around with your upper link placement (up and down on the chassis) until it goes away |

| Freq, here's a shot of my link set up, I went with what they suggested. I'm running Losi Slider shocks with 5owt. I have not tt at all, completely eliminated once I went with this chassis.  |

This does absolutly nothing to help the torque twist. Been there tried that along with many others. I just learned to use the torque twist to my advantage. | |

| I am running the DS chassis too and have not had any torque twist issues. I am running my rear links on the back top hole so get my driveline up a little bit, and mt front on the front top holes. You might want to play with your shocks a little bit. I am running to aluminum losi's too but I am running internal springs as well as outter springs. I believe 80 weight in rear and 75 in front. But like the others said the flipped tranny is not going to do anything for you. And to be honest with this chassis there really is no need to run it flipped. I will get some pics up tomorrow for ya. Good luck. |

get me a shot from the side where i can see everything. all the link angles look steep, whats the belly clearance? you might have to lower the truck down a tad to solve the problem | |

| x2, not sure but might be able to look into the shock inboard spreader DS makes to get it at a reasonable height. |

| after about 15 minutes of staring at you setup I notice 2 things that should help the problem, but I need an axle to axle (full length of the truck) pic of the top, and the same for the bottom, as well as an axle to axle shot of the side. Just cant make out that much on those tight angles. The very first thing I see is that both upper links are alot shorter than there lower counterparts. Extend them and move them to the second top hole on the chassis. The other thing I noticed was the springs, from the picture they look really, really long. I havent seen an "firm" springs for the MRC that are that long. If they are as long as the look its a good chance that they are your main culprit. If you are running aftermarket threaded shocks, then crank that collar down at least 3/8ths of an inch. It also looks like your truck is way, way to high. Which it doesnt need to be. Cant really tell though without being able to see better pics. Try that and get us some more pics.... Last edited by soundcolor; 05-09-2009 at 11:59 AM. |
