Canberra 40 was our first Canberra to fly and one of our first scale EDFs. Canberra 40 is designed around 40mm EDF units and has a span of 35” / 89cm. The prototype has notched up 200+flights over the past few years and is such fun and so easy to get to the field or take on trips in the back of the car that we can’t get round to retiring it. Electric reliability combined with great handling are a recipe for a long lived model!
Structure is a combination of liteply formers, thin ply wing spars and balsa sheeting. Canberra 40 uses the same jig built assembly process and carbon tube reinforcement in the fuselage as Canberra 50, which assures an accurate build and great strength in a lightweight structure. The Canberra has a large wing area for a compact model which allows for easy hand launches and close-in aerobatics. The classic Canberra combination of clean airframe, low wing loading gives a wide speed range and forgiving handling.
Propulsion originally came from GWS 40mm EDF units, with 12mm brushless motors (Feigao 5300kV) and a 1300mAh 3s battery. These were great little units and provided plenty of push - in still air the Canberra will climb on half power.
We had held off kitting Canberra 40 because the GWS fans and suitable motors became harder to source. Very recently we have been trying Dr Mad Thrust 40mm fans which deliver much more thrust but draw a fair amount of current. However flights on a 1800mAh battery in parallel configuration have been great, with an easy belly take off from smooth grass and easy flying at low throttle settings to keep from stressing the battery. It is going so nicely we will be kitting our little beauty in the New Year, drop us a line for details
