Lanier Indicator
they are great little planes. oddly enough, it was easier to train people on it with 2 full size and an hs-81 on throttle than later when we put all 81's in it; at least in wind! it was so lightly loaded it would get blown around in turbulence. a good flier, and you will train easily on it. the throttled 061 is way more power than needed, I hope you got throttle! it is very nimble, and great rudder authority, only use a little throw at first.
