What is the difference in Factor 1 MX5 - MX7 - MX9 - MX11 Updates
Can anyone help with this? Is it axles, birdcages, chassis?
Thanks in advance.

Looks like 2 digits per model. A good businessman will try to offer something for everybody, along with a line of Bull to sell each particular one to each particular customer. It all works they don't sell junk, and the only thing I know for sure is given enough time and knowledge you can make anything work. I remember back in the model airplane days there was a joke that if you had a big enough motor you could make a broom stick fly. A guy tried it and it did indeed fly.

It amazes me how racers can just keep on chasing that dream, knowing they will some day hit on that magic combination and run off and hide from the competition. I know I do>
