Ives seen almost every other team use flex wheels as center traction wheels but how? its not as simple as just replacing the center omni wheel with a 3 inch flex wheel as the omni wheels are 3.25. i know the robots sink into the field but by a quarter of a inch seems too much. how do teams do this?

most teams are cutting the spokes off the flex wheel it’s self and wrapping that outer layer around a high strength gear. I believe you also have to shave a little bit off of the inner layer as well, but I’m not exactly sure how much. Actually I think @Xenon27 did this for TiP last year, he might be…

exactly what I was thinking of but couldn’t, well, think of it. this should help op a lot

I have heard that the new traction wheels are quite good, comparable to custom flex wheel tractions. So if you don’t want to spend time carving up an old 3.25" traction wheel and a flex wheel, using the new tractions seems just as good.

While the new traction wheels are much better than the old ones, they are still not as good as a flex wheel. I am currently using the new traction wheels on my robot, and they work fairly well. Flex wheels are still better. Even better than the new traction wheels, are old omni wheels with the rolle…

[image] Dave-TBR: Even better than the new traction wheels, are old omni wheels with the rollers locked out. Locked omnis definitely don’t work as well as the new tractions. They have a lot less surface area and in my testing, the new tractions are way better than locked omnis. My worlds robo…

Maybe I got a weird batch of new traction wheels, or we have some special old omni wheels.

I stretched out a 4in flex wheel with a custom polycarbonate insert to 4.25in because I have 4.125in omnis. It’s nice cause you don’t have to cut the flex wheel. On the other hand I don’t know if this is possible for a 3in

[image] bobbybarton3: On the other hand I don’t know if this is possible for a 3in It’s probably possible, but would be harder to do as you would have to increase the diameter by around 1/4 inch instead of 1/8.

Ok thanks. imma cancel my order and order the new ones. also what team are you on or were on for worlds and what division?

Flex Wheel as Traction Wheel

3.25” vs 4” wheel traction VEX V5 General Discussion

3.25" wheels definitely do have considerably less traction, primarily due to the rubber being a lot harder and less grippy on the rollers compared to 4" and 2.75" wheels. But they also have a lot of advantages, such as weight, slim profile, mounting hole, and convenient gear ratios that still make them perfectly viable in tipping point, however I think to eliminate the traction disadvantage, having a middle wheel which is a custom traction wheel made from flex wheels is a good idea. I use 3.25"…
