The tank is a chicken hopper. 18 1/2 ounces. I have to check if it's run as a uniflo or not. Ken's probably right. Engine started right up at Huntersville, run time is three minutes plus. Initially, there were thoughts that the fuel system would have to be pressurized in order to feed. Dynajets usually sensitive to any variation in fuel head. Not a problem. First flight Dan did loops, lazy eights, I believe. Mike Palko put the plane over on its back did an inverted lap. Dan now can do every maneuver in the pattern. Issue at the moment is run time. Not quite long enough for a pattern. Engine will run on 87 octane but not reliably. At Huntersville Dan was using a propylene oxide mix. Started right up. Engine needs to be adjusted to match the temperature/barometric pressure(?), humidity(?), of the day. Dan's getting very good at getting the jetting right. I have seen many of Dan's projects over the years. This one has been comparatively easy to trouble shoot.
Dan flew the twin fox Bearcat in Profile at Huntersville. I think he came in third. Engine sound is a treat. Dan machined the cranks and crank pins for the double Fox. Randy Holcroft did the heat treatment. Nearly 30 flights on this engine so far.
