A couple devices from Atomic Annihilation for the Space Princess adventurer.
AEROCYCLE (DC 30)
If you need a super science vehicle to move you through the air while still leaving you vulnerable to ray guns, bullets and rocks, you can't do better than the aerocycle. I mean, sometimes it's about looking good, right?
The aerocycle can get you about 20 feet above the ground, max. and can lift two people at a time - for example a primitive swordsman and his space princess holding him tight.
Aerocycle: HD 3 | DEF 12 | SPEED Normal
RAD-SUIT (DC 15)
The rad-suit provides a +1 DEF and a +3 bonus on STR tests against radiation. It is a must for adventurers plumbing the depths of ancient fortresses that were once powered by primitive atomic piles.
