"Galoob Micro Machines Star Wars Pod Racers" Topic

Galoob made two sets of Micro Machine Pod Racers.
1st set were on the little black square base with four wheels that were to be shot off a launcher.
2nd set they were "based/mounted" on a clear angled stand.

Question is…
1. I know the set with wheels had all 10 pods.
Did the set with the stands have all 10 pods produced?
2. Were both sets the same size? Or are both sets the same thing, just one set was on wheels and the other set was on a stand?
3. Anyone have comparison pics?

I am pretty sure the set on stands only had two racers, at least that is all I have, and I was buying pretty much all the stuff (mostly ships) they were making (or I could get my hands on).
