Stand Alone Automatic Pitch Controller

How do you prevent a stand alone APC ( connected let's say to the bow planes) from cancelling out movents of a manually controlled stern planes:confused:

How do you prevent a stand alone APC ( connected let's say to the bow planes) from cancelling out movents of a manually controlled stern planes:confused:

Well for a start lets re-orientate the issue. i.e. APC should always be connected to the stern planes (as they are better at controlling pitch), the sail or bow planes help make smaller adjustments in depth.

If the APC is working to control the rear planes automatically, transmitter inputs on the bow and sail planes are not necessarily being cancelling out by the stern planes pitch inputs. It just might be the hull length position of the forward planes etc may not be effective - have seen this more of an issue in smaller scale subs than larger. A test you can do is disconnect the leveller off the rear planes, set the rear planes horizontal and drive the boat with the forward / sail planes and see what happens to gauge these planes effectiveness. I have seen some cancelling out occurring in a 1/72 Permit sub I built years back, but I have since found that was caused by poor weight distribution in the model on my part.

Re the APC as a standalone - a lot of the guys I run subs with here have 1/72 LAs that have no stern TX input whatsoever, they have an APC just autonomously working and connected into a 5v rail (not a channel). The only plane TX inputs they have are the bow or sail planes.

If you are still concerned about the bow / sail planes being cancelled out - you could use the APC in an active fashion, i.e. apply TX inputs to both bow and stern planes OR just rig up the stern planes with APC controllable also by a channel TX input.



Hope this helps.
