i have changed the motor/esc to the esc/prop from your storch light article bayboos as i want a more scale flight, but will swap between the two. i used a 10/4.7 prop (the one from the c power pack). it may have been that the esc wasn't calibrated, but it certainly wasn't underpowered, you can't tee the takeoff in the clip but it got off from long grass in abut a meter, and seemed to be a similar speed to my pz t28 (a bit slower). i might try recalibrating the esc tomorrow (it is almost night in the UK). the prop was the right way around, and felt pretty tight. it may be that my storch is too heavy, as i painted, varnished and sealed the edges with hot glue, but it seemed to balance perfectly with a 2200 implying it was a similar weight to the specified weight. i will inspect the prop and motor tomorrow.
