Rocket prop

Hello fellow rocket builders/owners im not really ready for an engine for my rocket build yet but i have possibly found a decent deal come up here in Australia on a i0540 C4B5 out of a wrecking Aztec "exactly what I'm after!"

The Aztec also is wrecking the Hartzell props. I'm not sure if they are suited to rockets or not the models numbers don't quite match up to what Iv read elsewhere. Is there anyone that could shed some light on this? This is the models on both props I have been given off the wrecking Aztec aircraft are:

Hartzell HC-E2YR-2RB$ & HC-E2YR-2RBSF,

Serial# BP8130E & BP1533, Both 530 TSO

The Rocket props have a unique twist in the blade (J blade?) Due to the higher cruise speed. Aztruck props will cost you many knots.

If they're full feathering props, they're probably not what you want.

No worries guys thanks. Much appreciated
