Q: Do you plan any more parts? A: The J-68 (reversible afterburner) was not completed on time for release and will be added in a future update. Additional parts are being considered.
Q: I don't like the balance of [x] part A: Kerbal Powerplants is a new mod, while we have done internal testing the only real way to know where the outliers are is with public feedback. Tweaks will be made in a future update.
