[NSRCA-discussion] Retracts?

[Robert Gainey]

It all depends on what wins and who is flying it ! Lets say for example, any one of the top ten pilots wins the world championships with a YS powered bi-plane equipped with retracts and counter rotating props. There's going to be a lot of used fixed gear electric powered monoplanes on the market !

Also, no retracts leads to less mechanical complexity, and one less point of failure.  But, I think the drag thingy is the main point...
