It can be used with a prop if setup properly but as it has been mentioned many times in this thread it is a high performance engine which somewhat limits it's applications.
If you would like to try it only use it in an low drag high performance airframe.
As far as how to use it here is some good solid advice.

From my own experience...
22% Oil (Sint+Castor)
APC 10x10
MCCoy MC9 Glow Plug
5% or 0% Nitro
No head shim
BVM Pipe
17800 RPM
Do not use spinner a spinner nut will be OK
Take care with the prop balance and check it every landing, when you see little clear veins discard the prop immediately.
