Good afternoon,
As per the thread of POSTS below, I am at a loss as to why I am having this issue. The current set up for all 6 submarines (ranging from 5 to 9 feet in length) is as follows...
- Single Mabuchi 550 Motor connected to a 3/1 gear reduction system exiting the WTC bulkhead with a 2 inch manufactured stuffing box.
There is minimal to no drag on this set up, and the shaft can easily be turned with your fingers.
- Each WTC contains 4 servos (Rudder/Aft/Forward planes/Ballast Tank) plus a maufactured (40A) Speed Control witha 20A fuse
The BEC capability was removed based on suggestion from the manufacturer support team and replaced with a nicad pack
- The ESC (one each per WTC) is inside a 4" OD cylinder which is 9 inches long
As per suggestion from manufacturer, one ESC was rewired to be outside the WTC and completely immersed in the water
- The ballast system is Propel, the props range in size from 2" (for the twin screw subs) and 3 to 4" (for the single screwed boats)
- All six subs used to work flawlessly when thety were "dry hulls", but since changing to a WTC sytem, I have had this problem
Because the set ups are the same, I have swapped out every mechanical part with my surface flleet (servos/speed controls/motors/batteries/and Radio Contol) with no change.
Using one sub as a guinee pig, the latest modification is that the ESC BEC has been disables with a Nicad pack installed, The ESC is now running the the water, all four servos have been changed, a new 40A ESC has been installed, a new 550 motor has been installed. Same problem.
FLJ, Thank you for leading me to this Forum !
