Lucky me, one more time before my new knee parts ship! Hope they're not from China!!! I got the Do back hovering like old times, can hold it until I'm board with it. By noon it got too hot to hover, it was 90 & climbing. I tried Powermaster for the first time & I'm very happy with it, its only the second fuel I've found that runs clean, the oil slick on the wing is a nice & clear light color, nothing but oil, Magnum is the other fuel that runs super clean for me.. Its only $12/gal. @ Chief, not bad. I havent got completely board with the Do yet,other planes look nicer, track better & do a few things way better(rolling harriers for one), but I still get "pucker" with it hovering inches off the deck.
