Finally got into the air on Saturday and had a couple great flights. Used a Top Flite 10 X6 Power Point (raked tip) on the PAW 19DS with standard Aerodyne diesel fuel, 1 1/2oz wedge uniflow tank. The engine had be test run on the ground to get the rough settings which were about 1 3/4 turns open on the needle and the compression were it was when I got the engine from eBay.

First start was by hand flipping, two chokes, hard flip engines started and was overcompressed, quickly backed out compression screw till it lost a little rpm then leaned the needle till misfire, opened needle 1/4 turn and adjusted compression for max rpm then backed off 1/8 turn.

On the flight line for the first flight I cheated and used the starter at the run compression setting but opened the needle 1/8 turn. One choke and applied the starter, in very short order it fired off and slowly came up to smooth run. Just as I was leaving for the handle it started to misfire so I opened the needle another 1/8 turn. I don't think it was all the way warmed up cause the launch was a little slow but once we cleared the grass it picked up speed and after about 4 laps it really came on. Since I wasn't sure about how long it would run I flew the Old Time stunt pattern maneuvers one after the other to see how it would do. It did really good. Seemed to bog a bit at the top to the vertical 8's and overheads. At the end of the tank the engine simply misfired about four times and quit nice and clean. Looking at the oil and with the bogging when the load came on it seems like it was a tad overcompressed.

Next flight I backed out the compression 1/8 turn, one choke, a couple flips to make sure is was hydr locked then applied the starter, off it went. This flight I felt there was enough fuel for the complete pattern, again took a few laps to come in but for OTS the first couple maneuvers are the climb and dive so not much power needed by then the motor was in and the wing over was no problem. This was only the fifth diesel flight I have flown ( one with an under compressed Drone, one with a OK Cub 074 and one with a ST 15D on a Jr Flite Streak and at the time almost had it right) I was very happy with the way it performed. Since changing to the PAW 19DS reduce the weight to about 25 oz the Ringmaster flys much smoother, it takes a bit to get use to the very lite pull. After the flight looking at the oil its now dark honey brown so I think its just about there. If all goes well over the next couple week I will use this set-up at the Fall contest in Starky, FL.
