ARF's are the worst. The last one I did, well, here's breakdown:

Seagull Spacewalker: $119 - said on box came with extensive hardware, spinner, etc etc. So of course:
Replacement H/W: $12.00
OK 46AX: $109 - because of course I'm not going to fly this heavy of an airplane with an LA 40.....
Fuel tank: $3.50 - It came with one but I didn't like it.
Piece of Hardwood to make pushrod mounts/cowl mounts/battery mount: $.89
Other misc. stuff I didn't like and needed to replace: $36.00
Voltwatch: $16.00
12" prop for AX: $3.50
Roll of monokote to seal between stabs and cover hole in fuse needed to install battery: $12.50
And it's not done yet, because as soon as I fly it I'm going to start thinking it needs a 4 stroke, so....
Saito FA56: $189

Than I've got an AX 46 sitting around with no airplane for it.... can't have that!
