Hi Yoda, Thank you for sharing the technical infos. Have you try mixing the elevators with ailerons? I use 3 trim sets on Jeti - Clean, Smoke, and Odnance trim for different flight config.
right now the shipping boxes are in 3 boxes. This would include the freight a bit but I like the plywood crates. The Ocean freight of $450 is just the shipping, not counting the custom clearance and ground shipping, a range of $800-900 shipped is a better estimate for your project.
