Yes, the Spacehopper is a beam mounted engine with rear intake similar to the Thermalhopper. On a Baby Flite Streak, I think an on the inside of the nose tank, or a bladder in the wing, would be necessary. I have a Spacehopper that I plan to fly some time.
Make sure you have plenty of reeds.
Plastic one lasted longer and make less power than brass.
Brass reed, 40%, 5x4 = about 3 runs max per reed. FAST.
