So it started out as balancing the plane. Testing showed that it required around 1.2Kg of weight in the front of the wings to get it nearly correct. Initially I had a single 12v Gel cell that was about right but latter found that due to its age it was failing under load. The solution was to get a pair of 12v 2A/h seal lead acid batteries. these cam in just under the required wight.
That is ok as I need to setup a pair of switch mode PSU's. one for the servo control system and one for the on board computers driving the SSD and cameras. Initial static test are ok.
Soon the body will be done and the basic avionics will be in place for test flights.
