World Models T-34 with an OS 46FX is an excellent combo for your second plane. You can use all the supplied hardware, it has an excellent low wing, can be propped for speed or aerobatics, comes with a nice cowl, I could go on.

The OS is a really well made engine just don't lean it out to much.

Magnums are crap, plane and simple. Four stars are nice but no sheeting on the wing seems a bit cheap to me and I think it's just a bit dated in it's design.

For $130 and no need to buy a bunch of replacement hardware the T-34 is hard to beat.
