We didn't have good luck with these tonight . [
] Out of 5 of these flown tonight for the first time , 3 have servo issues . My Citabria was on the first flight , about 5 min. in , when the elevator servo stripped . Another guy's Cessna stripped the rudder servo about 2 min. in on the first flight , and my buddy's Citabria stripped the elevator servo on the fourth flight . The other Citabria flew about 12 flights with no problems , and another Cessna went about 4 times without issues as well . Gonna call Product Support tomorrow , and see what they'll do for us . Shouldn't have any issues , as it sems to happen to others as well , but will keep a running report on what they do for us up here in Canada .
