I have had no problems backing out using the hard rubber grommets that come with the PSP cowl binders,I've also used old servo grommets,just cut them in half(round ones) and place a washer that is at least equal in size to the grommet,they dont squish out as much.Fuel tubing is better than nothing but its too soft,cant tighten as much.I finally had a full day flying the Showtime without dead sticking.Got a few steps of the trim procedure in,the added right thrust seems about right now.No other trim needed, it tracks straight in KE, still could go further aft on CG but will fly it more this way.Does slow HA KE quite well(no SFG),harriers are soooo easy. If using spoilerons, no ail. is needed at all,even does 'em w/o spoilerons but needed a lot of right ail. at times it was maxed to the corner. Seems to hover well, but I dont have the best prop on for that,loads down the eng. too much. I have trouble doing waterfalls, that rolling to right thing when a lot of elev. is pulled. Does same trying square loops,rolls right. I know I'll have to check elev. halves for uniform throw, after that-what??
