A decent set of pneumatic retracts, which is what we're talking about when we say decent, is upwards of $250 for a 60 size plane which is more than the plane in some cases. That's ridiculous!
If you go with the recommended 4-stroke engine for a .60 size warbird, in most cases you will end up spending more money for the engine than for the plane itself. This is no different than spending more money for a good set of retracts. What most people and I dislike the most is seeing a nice warbird doing loop, slow roll, and fly-by with the gear hanging down. That is just not right.
