Electric-powered Enduro initiation tail-firsters came first successful rubber-powered duration modela single pusher flight still vivid memory probably would have done well continue theme fellow Flying Bison Doug Joyce demonstrated nearly 40 years ago well free flight canard could perform Never forgot So some positive expectations launched Kanardeze ways design frustrating first flight stages yet end result delightful exhilarating model fly took two designs accomplish learned what score first did right second major obstacle lack pertinent design datano decent references Burt Rutan kind enough furnish details VariEze interpret style model envisioned did provide some basics Andy Lennon s report canard design RCM some clues especially formula locate mean center lift basic aerodynamics lean design became quite mechanical nature simple layout allowed equipment weights locate center gravity CG correctly plus mean center lift until first flights made After first launch very happy powered flight canard stepped right out solid flight handling very similar normal model few passes around field good climb angle established brought altitude glide tests motor cut dropped steady glide looked pretty fast sinking some up trim applied bled off speed lowered sink rate However low-speed point reached warning nose dropped steep divevery scary second scare full up no effect several seconds

made cause Canard Syndrome clear As originally designed wing/foreplane lift proportion did hold over wide enough speed rangea range probably would seen powered endurance type model FF Electric Enduro cure Canard Syndrome proved relatively simple once proper analogy made simply patched some chord onto foreplane made no other changes repeated attempts did create Canard Syndrome saw some areas could stand improvement lessons learned second design produced Among other things increased chord foreplane switched airfoil better lift characteristics lower speeds models appears foreplane chord should

flight canard stepped right out solid flight handling very similar normal model few passes around field good climb angle established brought altitude glide tests motor cut dropped steady glide looked

Electric-powered Enduro initiation tail-firsters came first successful rubber-powered duration modela single pusher flight still vivid memory probably would have done well continue theme fellow Flying Bison Doug Joyce demonstrated nearly 40 years ago well free flight canard could perform Never forgot So some positive expectations launched Kanardeze ways design frustrating first flight stages yet end result delightful exhilarating model fly took two designs accomplish learned what score first did right second major obstacle lack pertinent design datano decent references Burt Rutan kind enough furnish details VariEze interpret style model envisioned did provide some basics Andy Lennon s report canard design RCM some clues especially formula locate mean center lift basic aerodynamics lean design became quite mechanical nature simple layout allowed equipment weights locate center gravity CG correctly plus mean center lift until first flights made After first launch very happy powered flight canard stepped right out solid flight handling very similar normal model few passes around field good climb angle established brought altitude glide tests motor cut dropped steady glide looked pretty fast sinking some up trim applied bled off speed lowered sink rate However low-speed point reached warning nose dropped steep divevery scary second scare full up no effect several seconds

speed lesser chord will reach its zero lift speed sooner will wider-chord surface can assume case canard low speed will reached lift proportion between wing foreplane will disintegrate end factors made cause Canard Syndrome clear As originally designed wing/foreplane lift proportion did hold over wide enough speed rangea range probably would seen powered endurance type model FF Electric Enduro cure Canard Syndrome proved relatively simple once proper analogy made simply patched some chord onto foreplane made no other changes repeated attempts did create Canard Syndrome saw some areas could stand improvement lessons learned second design produced Among other things increased chord foreplane switched airfoil better lift characteristics lower speeds models appears foreplane chord should
