The good: Why settle for a mere 200' when you can possibly reach 2000'? I changed the stock Estes 18mm motor mount for a 24mm mount.

The bad: Estes might need to work on their quality control a bit as the plastic pieces were warped and had to be bent to fit into place for cement. Also, the balsa fins were punched irregular and are horribly fragile. The fins need a lot of patience with filling the irregular gaps with wood filler, titebond slurry hardening and sanding.

Patience is the key to this kit.
