  1. Fitting an oil thermostat may help to bring the oil temp up faster. https://www.aircraftspruce.com/catalog/eppages/xcomthermostat.php
  2. My oil temp is generally equal to or slightly higher than cht. Cht's generally in the 90's and I do push the rpm's. Rarely do I reach 100 c cht but do go above in 100 c oil temps in climb.... I personally wouldn't like cht's much above (if at all) 100 c. If you are getting that now, summer is going to be difficult. Course pitching is know to give higher temps. Especially oil.
  3. Well, it's the floats that control the flow into the carbies and therefore also the pressure. So that might be something to look at. (As well as the needle and seat) There have been bad batches of floats in circulation for a while and I thought it had been sorted but a local Vixen with several hundred hours was found to have bad floats recently. The flow to the fuel pump in not impeded? No blocked filters, kinked hoses? Disconnected at the pump inlet side, the fuel flows readily out the hose from the tanks? Tank air vents clear? Any sort of restriction on the suction side of the pump, alows the posibility of vapour being pulled from the fuel. As a long shot, the carb vent lines? Generally they give mixture issues if poorly placed in pressure/ vacuum areas. If using a sealed cold air intake, they should be attached to that. How are you measuring the pulsation? Definately no suspicion there?
  4. I have heard of some owners doing away with the plug completely and just fitting the 6.3mm spade connectors individually. That way you can "feel" how each connection fits (tight or loose).
  5. As it will be a new class, I imagine ANY aircraft that fits the requirements can be registered. ie, heavier than 600 kg RAA "amateur built" and lighter than xxx kg mtow currently built as VH exp..... I take " amateur built" to mean anything that is not factory built? Plans built, kit built..... Initally limited to 760 kg, then 1500 in the future. I'm a skeptic like you Jaba....just repeating what was said....
  6. I attended a presentation a few weeks ago and asked that exact question to the president. His answer confirmed owner maintenance for the over 600kg class in amateur built. I can't recall if that included non hire/reward factory built or not. My previous impression was all aircraft over 600kg would be lame maintained.
  7. Bloke mentioned Diamond and Tecnam twins, so he's not short of cash..... Go Diamond.... DA 42, 4 seater. Diesel engines drinking jet fuel.... cool as...
  8. It's all ok until it's not ok. Does the driver/filler change? Who does it when he's sick? Alot of variables in the supply of your fuel and the first time you realise there is a problem it maybe in flight. There is another thread here about diesel in fuel getting into and diluting the engine oil.
  9. I'm also not sure I get your question. Ozrunways has a "document" link to the various airports. This will give all the info on each airport. The only real restrictions are airspace and controlled airports.

  11. Get Ozrunways app. Free trial.... may help.
  12. People say, "I prefer steam gauges. I don't like any of that new fangled glass stuff." But really look at the situational awareness it can give you..... as per the above post. The accurate and instant live information available now is pretty miraculous...
  13. I have had a good look at Poteroo's Brumby and I don't think I've seen a "visually" stronger Looking RAA aircraft. So many rivets and a super strong undercarriage. The empty weight of 365 (?) Kg seems to support this as well...
  14. Sssshhhh......don't give them ideas...... CEO will have the calculator out crunching numbers about how much he can scam off owners..... while spruiking "No fee increases"...
  15. Just throwing it out there, but I imagine the prop pitch is set correctly?
