Default RE: Wheels only sold in sets of 2?

The vendors know what quantities are typically required. So, wheels are sole in twos whereas we often require three. Similarly, servos are solved in quantities of 3, 6 and 12 when sold in bulk whereas we often need 4, 7 etc. That way you definately need to purchase the additional unit.

But go ahead and purchase, it will help you in your next build. For example, I bought 6 servos twice and used 4 each time. Now I have 4 servos spare for my next project and I could purchase only 3 next time
