  1. Sir Tim Wallis, the founder of Warbirds Over Wānaka, died peacefully on Tuesday. https://www.facebook.com/100064626048241/posts/pfbid0eG52X3rDcVWMUmPibaeuUNXnoRiQJFaWsNRaMEAtc6QTEEBwCdikkDBSrqqrgAzMl/?mibextid=cr9u03
  2. The CAA report has been released https://www.aviation.govt.nz/assets/publications/fatal-accident-reports/22-4516-ZK-MGB-Fatal-accident-report-Final.pdf NZ Herald article https://www.nzherald.co.nz/nz/franz-josef-pilot-tragedy-pilots-wife-mates-urged-him-not-to-fly-on-day-of-fatal-mountain-crash/CL6OGDLYFZCH3NNP4HZM2MPAWM/
  3. Battery may be 'light' however moving it from forward of datum to rear of datum can make a difference. You can use Ozrunways W&B to do what if's. You can add new stations easily. If you do add weight near the tail, you need to be mindful of structural limitations as there is 'less aeroplane' back there.
  4. Good to see you getting around in your Archer. I just got my Cherokee type rating in an Archer in the weekend. Good solid easy to fly machine with plenty of power.
  5. Glad you were able to tell the tale Glen. I hope the supervising instructor has been fully briefed on this incident. We lost two fine pilots and people on a base leg collision a few years back. They weren't as lucky as you. I also think training aircraft should have ADSB fitted for many reasons.
  6. I used Skyfuel when I was in Australia. Great service and network so very disappointing to see. We have a similar issue in NZ at the moment. Gofuel was a AIr BP carnet provider however decided to go with Z Aviation. Air BP got wind of it and shut down the Gofuel cards. We only have BP on our airfield so its made it very difficult. Most of us have applied for RD cards who provide Air BP cards. We have been told that we can apply directly with Air BP however the general feedback is that its a nightmare trying to get a personal or aero club card. Recommendation at the moment for NZ aircraft operators is RD if you need Air BP pump access.
  7. The ADF was also useful for listening to the current cricket or rugby game. Good to see you using the old tech.
  8. No recession Glen. A bit more info. Double springs installed. Non Jabiru forged pistons were installed at the last rebuild hence the lack of valve relief. This was due to the problems we had with the then supplied Jab pistons (that's another story/thread) I'm going to remove at least one more head (#2 which runs the highest temp) Thanks for the comments so far.
  9. Good suggestion Nev. Used to dealing with cryogenics (mainly LHe in MRI scanners) and LN is readily available. Maybe I wouldn't need to heat the cylinder head if I used that method? My research so far indicates 7 thou OD oversize seat for aluminum heads.
  10. After a couple hundred hours of trouble free motoring since a major rebuild, I have experienced the first issue with my 3300A engine (SNo 33A1240) I had completed the usual 25 hour oil/oil filter change along with leakdown tests (>78 on all cylinders) A ground run was completed. No issues were observed and after a visual leak check, the aircraft was put to bed. The next morning I decided to go for a few circuits to ensure all was well. During the preflight, I rotated the propeller to check for normal compression, noises, etc and I noticed a lack of compression on one of the cylinders. I narrowed this down to #6 cylinder exhaust and removed the head to find a dropped exhaust valve seat. Photo attached. It obviously happened during the ground run. This cylinder has reasonable temps sitting around the average (130 deg C in the cruise)and runs a little rich (as does #5) I predominantly use Mobil 95 mogas. There seems to have been minor contact with the piston so I intend on replacing valve, valve guide and seat. I am an engineer with a background in avionics and mechatronics and do not profess to be an engine expert, so anyone with ideas, similar experiences, questions or other comments very welcome.
  11. As the prospective buyer in May 2020, this crash is close to my heart. My initial inspection was enough to decide not to purchase the aircraft. The engineers inspection confirmed it was the right decision. If I had decided to go through with the purchase, it would have been a new engine. My thoughts go out to all involved with this tragedy.
  12. I made the mistake of buying one of these. I have finally retrofitted the POS % gauge with a real gauge and it seems to work ok. Didn't check the orifice in the block. Maybe I should....
  13. Point 1: Airfields can be great waypoints if you are well above pattern altitude. Point 2: A lot of pilots now fly direct from A to B following the magenta line so waypoints slightly off track can be a good thing to avoid being on the same line. Point 3: Use your recommended cruising altitudes when cloud cover allows.
  14. I brought this Chinese made VHF antenna a few years ago for my boat. Works fine however I still keep an eye out for Winres. Nothing worse than being kelled!
