Posted by The arrival of my avionics panel is imminent and I will need to fit the LRU rack. To do so ideally the front composite needs to be in place to secure the avionics first rib. With the front composite and LRU in place, access to the heater, fuel pipes and rudder pedals will be difficult.
So finished off the rudder pedal riveting to the floor and pedal rivet, ensuring free movement in the plastic bushes (I had earlier filed the lock plates and bushes for a smooth movement). Rudder pedal assembly install is quite difficult in a QB, as you have poor access.
Attached the rudder cables and steering pushrods. Torqued nyloc nuts AN3 to 3 Nm and AN4 to 8 Nm and marked.
Fitted booster pump. Assembled so that it can be removed with its attached hoses and check valve as one. Likely the SAE R9 fuel hose will need replacement when needed on condition in 5 to 10 years time.
Fitted heater temperature control wire. (removed 200 mm from the 1m Bowden tube). Per Evans video.
Fitted heating hose, ensured hose clamps well seated. Would be fiddly to fix later.
I am using the large ‘Rotax’ firewall hole for all electrical connections. Because the large Rotax connectors have to pass through, there’s a large hole to be filled. I remade the kit ‘horse shoe’ plates to a smaller diameter (34 mm to close up the hole. The remaining gaps to be filled with high temp RTV.
