Please forgive a newbie's ignorance, but I'm a recent convert to this hobby and having a blast!

My first plane was an ARF trainer, and I'm dying to get a Warbird - specifically the Spitfire.

I realize moving from a trainer to a heavy tail dragger is not typically recommended ..... <flinching while awaiting replies>

However, I had an opportunity to purchase a mint condition OS-120 four-cycle w/pump at a ridiculous price. Now I want to stuff it into a World Models Spitfire, specs below:

Wing Span: 63" / 1600mm

Wing Area: 704 sq.in. / 45.5 sq.dm

Flying Weight: 7.5lb / 3300g

Fuselage Length: 53.5" / 1350mm

Flaps

Will I be able to land this puppy at less than 50mph?

Somebody please tell me this is a workable combo....... please?

Thanks in advance.
