Hi, Have never built anything with wires over a few inches however seems your not the first to find long wire runs directly from Arduino are not ideal - https://forum.arduino.cc/index.php?topic=19254.0 https://forum.arduino.cc/index.php?topic=483371.0 The second link suggests CAT5 Cables would give you more reliability and might be a quick fix - if you wanted to go the full on engineering route, the first link suggest line drivers or differential signals - have never used either approach but if you want reliability you should probably investigate both Duane

Hi, Has anyone experimented with a forward angle that would generate lift on the non surf side for example if the boat is moving -> an angle something like / to lift the non surf side and push the surf side harder into the water like a dynamic ballast effect ? I have fixed gates so cant try for myself but would be interested to know the effect Thanks Duane.

Hi, have not read the full series of posts, so apologies in advance if this has already been eliminated as the cause but - I used to run this Arduino Website - rcarduino.blogspot.com before switching to boating. 9 out of 10 issues with Arduino projects are current draw from a motor or servo pulling the voltage down so the Arduino resets - the other 1 out of 10 is electrical noise from the motor. Have look at this old post and part 2 of it for an explanation and demo - http://rcarduino.blogspot.com/2012/04/servo-problems-with-arduino-part-1.html I used to use Arduino for all sorts, including RC Vehicles where there was noone in attendance and reliability at a distance in a performance high noise environment was key. hope it helps Duane B
