robo challenge wheels

i recently purchased some robo challenge wheels with nut inserts and 1 wheel is fine but the other wheel the thread inside is damaged! so i cant get it on the thread of my motor. what should i do? :cry:

Call RoboChallenge

thanks :proud:

If you can get 3/8 UNF tap, run it through the nut inserts. That should fix it. But Kane is right - a call to Robo Challenge is best. They are a good bunch and I expect they will sort it out quickly for you.

Ive got your email thank you. We will be exchanging it for you. I apologise for the inconvenience.

thanks
