I was looking at the ads for the LHS in your first post and see that he's asking 12 lbs less money for the 46 LA than the 40 LA. 46 better engine and cheaper? No brainer there. 46 is the way.

You could also save another 15 lbs with the futaba 4 channel FP4YFN radio. Still better than the GWS.

Plane 50
engine 55
radio 110
Total = 215 VERY close to your stated limit. can't you save a few more pounds by spring?
