Friend has been having problems with "vapor lock" particularly at take off power.

Aircraft is Pelican, high wing, L and R wing tanks feeding through a L-Both-R-OFF selector to a gascolato ...

Thanks Doug - will look at that.

I asked an A&P friend how to find the best rigging for a 701.

he said the way is to find someone with the best flying 701, and ask that person Smile

Any volunteers for fine tuning flaperons, f ...

With the Hackman kit, did you have to drill a port in the Bing? The Bing on my J2200 does not have an existing port to use.

Some guys in Australia have devised an oil catcher which sits on top
of the engine, in that oil breather line.

It catches the oil normally blown out and returns it to the engine, so
you are using ...

These caps vary.

You need to check that you have sufficient fuel flow without extra venting.

Drilling out the 4 vent channels on the rim may help. Beware - the cap is quite thin.

Check.out the Matco site. They have it all documented. It takes a reasonable amount of pressure to push fluid up through the system. A light mineral-based oil will work well. [quote][b]

Well, I tried Roger's idea of cleaning things up and ground running at 4000rpm.

Before this, I resealed the threads on oil pressure sensor and oil pressure spring threads with Loctite 567.

A ...

Many thanks to all who gave a wealth of information on finding this. I WILL track it down and post result !

Hi Listers
I have a very slight oil leak somewhere near the lower front of the engine.
Not enough to show in oil usage - at 850hrs still does not use oil between 50hr changes.
But enough to run ...

hi List

have a VDO gauge and sender 10-180 Ohms for oil temp.

It has gone to full scale reading, and will not respond to either earthing or higher ohms at the input. The sender is working OK.

thanks Ken

Yes, Dynon make two levels of torque in servos, and did have an even
heavier one.

I had both, and put the stronger one as the roll servo, thinking it
would be seeing more use. I may ...

hi List

I've just fitted a Dynon SV32 pitch servo to a Jabiru J170C, but not yet test-flown.

It certainly has some heavy work due to the two cables and the spring trim it has to work with.
...

ooops .. as sensor resistance decrease on temp sensor, but increase on pressure sensor, gauge value increases....

I've now come across dual station sensors, which will support two gauges by two wir ...

hi List

I have a Jabiru J170C which has VDO 3 wire (+, - and sensor) gauges and sensors for oil temperature and oil pressure. As sensor resistance increases, gauge values increase.

When I inst ...

Thanks to all for your various comments on this.
We've swapped in ignition modules from another engine and it now runs. We need now to work out why the original modules failed Sad

A friend's engine has abt 300 hrs.
There is no spark at the plugs.
The AC voltage into the ignition modules is abt 9v.
The DC output from the modules to the coils seems to be about 2v.

hi Listers
has anyone put toe brakes in a Jabiru, and if so, what did you use?
thanks

thanks Phil, and pleased at your success woth the Bully Hawk !

Unfortunately, the a/c was caught up in floods, and rats chewed the
wires of both ignition modules, so the cheapest replacement is th ...

hi Listers

has anyone used the Rotax 912 “advanced start” module, which is sold
as a PAIR under the part number 881 280 ?

thanks
