Here is a view forward from the sing spar / engine access hatch. The main spar is currently two separate stubs that are bolted to a machined aluminium ring with four Jesus bolts. This is pretty strong - I've really tried to bend them upwards and nothing as moved, but I am still going to replace them with a single pass-through unit. Obviously the previous owner was going to keep a fan in here so he needed the maximum airflow through. I'm not as worried at this stage!
Further up the fuselage is the dual redundancy power switch (with two 2500mAh LiFe cells attached) and the main gear retract, in the down and locked position..
