I won't debate the performance of an EF airframe, they're among the best...
But
I don't think it should cost double to ship a 74" or 76" or 78" or whatever versus a 71" Slick. Sorry... that's my opinion and I'm entitled to it
I don't see the difference between the 3DHS and the EF planes I know shipping costs for. The combined costs are pretty much the same for the popular brands, if you work it by adding the cost of the plane and the cost of shipping and dividing that by the weight of the plane after assembly. Here are the prices I know of delivered to the Tampa Bay area, and some go back a little more than 12 months. I know that 3DHS and EF like to clear out inventory, and I've seen deals on green MXS's, which were probably not popular, the 68 Velox before they went to 70 inches, the Vyper, but besides these fee 'deals', it's all pretty much the same when you look at the final product sizes.
10 lb 70 Extra EXP: $389.95 + $64.83 = $454.78 = $45.48 per lb
10.3 lb 71 Slick: $439.99 + $38.82 = $478.81 = $46.49/lb
10.8 lb 74 Edge: $439.99 + $45.21 = $485.20 = $44.93/lb
12.6 lb 78 Extra: $449.49 + $126.99 = $576.48 = $45.90/lb
14.0 lb 83 MXS: $479.95 + $160.00 = $639.95 = $45.71/lb
3DHS is $45.71 and EF is $45.70... and each are a bargain, IMO, compared to the other brands that come to my door at any price.
There are other brands that also have low standard shipping rates, but when you consider that you would have to buy things like CF landing gear, and other items you would expect at that model price, it gets really expensive. There are other products that can get here fairly inexpensively, and come with nice bling packages included, but I pay tax on them in Florida, and I'm not as crazy about the way they fly as EF and 3DHS anyway.
