Well, if the whole model ready to fly weighs 74 oz then it's way too heavy for the 061. Those numbers you gave a couple of posts back don't make any sense at all then. WHere is the weight?

1# 7.7oz both wings
2# 4.6oz Fuselage with servos and receiver
14.1oz battery and balance weight

Ohhhhhh... now I see The 1# is one POUND 7.7 oz for the wings.

I haven't seen the # sign used to indicate pounds for years. My mistake.

I way burn that Aerofly as the abomination it is Nothing should be that heavy and expect to fly thermals. I don't know what it would fly like on the slope but at that weight I would think it would still be a mushy and heavy feeling performer. I hate to say bad things about any model but this one sounds like it's just way over the top.
