Results were pretty good: Stock: 16040′ – lost control: RTH With my booster: 16936′ – lost control: RTH With David’s booster: 18857′ without losing control. 5 bars on video, 1 bar on control I didn’t push it as I wanted to make sure I had enough battery but it was no problem. I flew ATTI only for a short section on the return and landed with 26%. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Do to high demand there is currently a ~ 5 TO 10 day lead time ~ I print all my items to order. When your item is done printing I check the item for defects. Then I prep the item (Sand, File & or Assembly). Then I VAPOR SEAL the item. This is done with a Chemical bath. By Vapor Sealing the item the result is a STRONGER item & it gives it a more “Injected mold” Look by smoothing the Appearance of lines left by the printing process. (This is more visually noticeable in Abs then Pla) I make every item like its going on my Quadcopter so you can be sure you will a Quality part. I have 100% Feedback because I WORK with my customers.
