Some good news and bad news!

The good news is I went to the field and after some changes ran the turbine with no problems. I tried some things out in stages - after initially posting I went to the field, removed the filter and did some more running. The problem had got worse and I had flameouts on the ground. I then took it home replaced the battery for the turbine, re soldered various power supply connections and made sure all plumbing and wiring was totally secure. Went to the field today and it ran great but only had one flight.

Unfortunately during this flight I had an undercarriage problem. For those of you who don't know the Bandit ARF, there is a door that comes up to cover the nose leg after retraction. The door was staying open after the gear was up. I tried a couple of manoeuvres to encourage it shut but it wouldn't go, so I tried to cycle the U/C. It partially dropped 1 leg and wouldn't do anymore.

I fly at Floyd Bennet field in NY with nothing but concrete so basically had to land with 1 leg slightly down on the hard stuff. Lukily damage is very minor, with scratching to the underside of the fus and horizontal stabs and nothing more. Wings are untouched. Managed to take the speed right off and get the flaps back up just as it touched down so they were not damaged.
After testing on the ground it looks like when the nose door did not close the ram was trying to pull it shut and leaking air. The system had good pressure before takeoff which had been checked on the gauge.
