ABC Dragonfly engine

[TimK]

Any suggestions for an ABC Dragonfly, whatever scale? Or an easily available engine which could be modified?
It would open up some interesting model possibilities: Wikipedia lists 17.
The only kit I've heard of with the Dragonfly is the expensive and hard-to-find 1/72 Ardpol Avro Manchester.
Thanks!

17 - most of which were prototypes with Wikipedia often having comments like:

but did not enter service owing to the failure of its engine,

That's my kind of aeroplane!
