Thank you all for the esc advise. Any tips for preventing the hatch pulling out?
A lot of guys tape the hatch down, but I do something a little different. I show a picture of it on the Post: Spartan Servo Glitching.
I always tape the hatches on all my boats. Not only secures the hatch but also seals against leaks.
The Spartan is difficult to tape the back of the hatch without modifying the "vents" on the back of the hatch.
