Thanks bigbird , I agree with you on the down trim I had some in ,but knowing I was being filmed I guess I got distracted .The flight after this one I greased it in a couple of times with no bounce at all . At the end of the day I got stupid and too cocky and stalled the plane into a 70 foot wide slough . Lost the cowl but everything else seems ok . Washed out the engine ,reoiled it , cleaned the radio gear with alchohol etc. I did find a replacement cowl on ductedfans.com. so she will be up again in a few weeks time .
