HorizonHobby.com How-To: Understanding Roll Center Adjustments on the TLR 22 Buggy and TLR22T Truck

Please click "Show More" for links, description and more information.
The Team Losi Racing™ 22™ Buggy and 22T™ Stadium Truck both offer exceptional out-of-the-box performance and tuning options. One tuning option that can be both extremely useful and extremely confusing surrounds changing what's call the roll center. Roll center refers to both the distance between your lower suspension mount and the upper ball stud mount and the distance between the lower suspension mount and the ground. There are two common references to the roll center, either high or low. In the USA, most racers have found the low roll center to be the way to go with both the 22 buggy and 22T truck, but in Europe, high roll centers tend to be more preferred. Todd Hodge was one of the key people that helped make the 22 and 22T a reality. He spent some time with us to discuss what roll center is, how it works and why it's important. He also talked with us about the importance of anti-squat and pro-squat, and how all of these adjustments change the handling characteristics of your racecar.

It does not come RTR with a mid-motor setup, however the parts are available separately to convert your car over.

More vids like this please. I'm trying to learn how to tune and this vid greatly helped

Thanks for producing this video! It's great to have a factory driver take the time to explain some of these more obscure settings. The explanation on anti/pro squat was awesome but I'm afraid I didn't really understand the roll center adjustment. Would someone mind clarifying what result this setting produces on a particular track? Thanks again!

Thank you for sharing I'm just learning I'll be watching for more

Thank you for the tips.

I was wondering what the difference between high roll center (HRC) and low roll center (LRC) is. Thank you.

awesome video!!!

Great info here.

i am not sure the roll center height has anything to do with dog bones movements. lower rear center simply reduces the rear weight transfer, holding spring rates and everything else in the setup constant. this would make the car having "more rear traction" and less prone to spin outs.

good one

Do the losi upgrades come with instructions????

[@seanannersnum1fan]

is it possible to get the 22 mid motor configuration in an RTR version?
