should I worry about the note that says HIGH SPEED LOW LEVEL MILITARY JETS OPERATING RANDOM ROUTES. sorry for all the dumb questions

So can I fly Dazza's route back down the coast without ATC clearance

Just a lowly RAA cert no ppl

The flight plan sounds good, the whole area looks like its full of restricted air space , Dalby then Caloundra direct cuts through some

unsure about ATC clearance

thanks all, I have printed everything so I have some study to do . hoping it won't be to hard all new country for me

This looks like a easy trip and maybe come back down the coast, how far off the coast do I need to be

Could any one give me some clues on how to go to Caloundra from Dubbo , looks like a nightmare trying to transit west of Brisbane , should I track further north then cut back to the coast , don't want to get mown down by a military jet, any help would be great

Point taken , I thought most had separate switches. I rang Floods to ask how they primed the filter and as you said they can't be filled so they crank it over on the started , ignition off or grounded , till they see some oil pressure , didn't think hand cranking would ever fill the filter. I didn't ask if they, as engineers, had ever read the Rotax manual ,

I never said to pull the plug leads off with the ignition still on , sorry if that was not clear.

thanks for all the reply's, lots to consider

I have tried giving the starter a 4 or 5 sec spin, ignition off, engine hot, then checked level , then cranked it over by hand but no change on stick , my engine is a 914 with 1300hrs up so it may be a bit worn allowing more blowby.

I would have thought if you took the plugs out there would be no compression blowby hence no oil return to the tank

Would there be any advantage in fitting a Air Fuel Ratio gauge, seen one fitted to a drag bike looked like it could be helpful in keeping a check on engine tuning maybe better than pulling and checking plug colour

To take one step further, to check oil level after flying could you crank engine over on starter for a few seconds with ignition off

Thanks for that , is there a way to screw the filter on without spilling any oil, the machinery we operate all have vertical filters so not a problem

Would there be any difference in using the starter rather than cranking by hand

After changing filter and oil would it be prudent to crank the engine over on the starter , ignition off, till the oil pressure starts to come up , unsure whether this could do harm or be beneficial in not starving any components of oil on start up

I haven't seen any others but I don't think there are many 914' s out in there, looks like it was made to suit this aircraft. I fitted a temp probe in the air box and they rarely get above 40c . I bought the plane off the bloke who was building the Spitfires in Queensland so I guess the intercooler was made locally , it is a tight fit inside the cowl.

Engine temps would have been low as it wasn't long after warm up , unsure about EGTs , the engine is fitted with a intercooler thanks to the previous owner so the air box temps are always low . I realize it was poor fuel but wondered what was happening internally ,once I eased the throttle back it ran OK ,only seemed to falter in the boost range. Thanks for the input.

So do you think it could be detonation that is causing the engine to falter

My engine does not like to run in the boost range if the fuel has gone a bit on the stale side which doesn't take long , unsure what is happening inside the combustion chamber to make it run rough , below 30 on the map gauge its fine , would the higher compression cause it to detonate , air box temps are cool so I guess internal temps would not be the cause. It took a while to figure out what was going on. as soon as I swapped the fuel over for fresh it came good , tipped the old fuel in the bike.

We fitted bypass thermostats to the intake side of the radiator , the bypass line is connected back into the same hose, easy to do, done over 600 hrs on my 914 , no more bits of cardboard on the radiator. doesn't warm the engine up much quicker but holds temps on long descents a lot better . We bought them through JG worth a try only down side is more hose clamps. Again sorry for the bad grammar , takes me back to high school when me and storchy sat for our English exams or should that be storchy and I

Remember folks, sorry my mistake
