A YT video on this issue just popped up in the feed which might be of interest.

For the time-poor, a short version can be had between  05:50 and 07:50

(though it goes on to show the same technique applied to engine cooling strategies).

 

 

 

Thanks Gary.

Enjoyed an overnighter in the Nynja with Sandy at our favourite bbq beach site catching up pre Xmas with flying friends then an early start back to Palmyra for the Mackay Aero Club bbq event. Hazy skies due to our bush fire season.  Evening was cool due to 16 Knot ESE breeze and that was welcome after the warm day.

Pretty sure no one has said on their death bed, I wish I had not taken my aircraft to the beech all those times.

I think a bloke that fastidious and also in the marine industry might know how to look after his aircraft.

Plenty don't, but it Pays to. Salt is Like cancer to Aluminium and unprotected steel.  Nev

i don't want to go off topic for long but since it has been raised.

what is the lifespan of aluminium seaplanes that live in salt water like the  sydney seaplanes.

i imagine each annual would have a rigorous inspection but there must be places where you can't get too.

They are a nightmare. Even getting the Spark plugs out can be difficult. Even Banner towing over the Beach makes steel fins rust off the cylinders. Nev

Current job is fitting the cabin heat unit I purchased in August last year after a cold flying trip out west over a few days last year.  Got the wrap fitted last night and while off the motor took the opportunity to loosen the exhaust pipe clamp screws so I can point them more towards straight down rather than swept back, should clear the exhaust gas away better.  (This required the patience, flame heat, WD40 to penetrate and slow back and forth to clear the rust, skills learn many years back and reused at times:)  

 

Found the cap crews badly wasted (450 hours and 10 years) so plan to replace again in 300 hours time.

 

Next yew days will cut the fire wall penetration and fit the valve to open and close the heat.

Ball end with tension springs can Be a solution Bolts and set screws can lose their Heat treatment. Instal with a Heat proof antiseize and replace on a suitable schedule. Nev

Agree, originals were with Kopper Kote and 450 hrs so plan relace again at 300 hrs.  (Thought I may have had to drill out threads and use bolts and nuts etc; but threads ok so do same again.)

Received my s/s id plate for the Nynja  today’s mail. At $20 real value from Mydogtags in USA.

Thanks FlyingBaz for the lead. Cheers

Closeup of cabin heat fit.  Not screwed down fully as need a hand on other side to tighten fastenings. 

(A new exhaust spring is to be fitted as can see wear on coils from safety wire. I just use red silicone paste in future.  also put kopper Kote on spring ends, Rotax UK do that)

Nice clear Pictures. Nev

When you replace your exhaust springs put your safety wire up the centre of the spring and squeeze a bit of the high temperature silicone down the centre of the springs . It stops the high frequency vibration from wearing spots on your springs. Since doing this I have not had to replace a spring in the last 10 years.

Blueadventures, 

Curious - The exhaust springs shown, second photo above, are they Rotax issue?😈

Ummm… What’s the black thing on the bracket in the bottom of the 2nd and 3rd pictures?

Will be and I'll place Kopper Kote anti-seize on the spring to the lugs.
