Pulsejet Long-EZ now very fast!
I've replaced the original PJ8 pulsejet prototype with the pre-production (second) prototype on which all the manufactured engines are based. The production engines actually produce quite a bit more than 8lbs of thrust and (as you can see in the video) this really makes a big difference to the Long-EZ's performance.
This was a short flight. These engines are thirsty, the Long-EZ tank has a small and I don't think I filled it all the way.
I've now reflexed the ailerons of the Long EZ, setting them to be about 3mm up at the trailing edge. This has vastly improved the handling of the whole model and improved elevator authority a lot (it caught me out when flaring for a landing) but now, the plane no longer drops a wing and I was able to control the bounce very easily.
Next up: the pulsejet-powered ARF Bobcat -- it's nearly done!
