RE: engine ?
The .32 F (not the newer .32 SX) is worth in used shape about $50-$60 US at best IMO, I sold a few of them on the bay over the last few years when I was getting out of helis.
A brand new .32 SX only sells for about $120 US brand new. The older F seris was either ringed of lapped, and has a different head and carb. Its a decent engine but fairly dated - power is down quiat a bit fromt he "newer" SX which itself is allready about 10 yrs old.
