Found this on e-bay. Unfinished helicopter project. Even comes with helpful advice on making concentrated hydrogen peroxide for fuel and apparently it could theoretically take off from under water. Any budding Q's or 007's out there??

INTORA FIREBIRD & ATLAS HELICOPTERS (UNFINISHED PROJECTS) FUELLED BY H2O2 | eBay

Not me, I quite fancy a Tiger Moth...

"powered by Hydrogen Peroxide"

So a helicopter driven by rotor tip rockets

No tail rotor but lot's of noise and probably a relatively short flight time - No Thanks!

H2O2? ISTR that the German interceptor of WW2, the Komet, used that as part of its fuel mix and apparently fuelling accidents dissolved a couple of pilots alive!
