G"Day All,
I have had the fun and pleasure of owning and flying one of the best prepared and rigged Yak 52 here in Australia.
VH-XSU was imported and completely rebuilt by Lindsay Sinclair from Redstars Aviation as his personal aircraft.
Time has now moved on and I am about to take delivery of a Yak 18T.
I am going to install a smoke system. The problems are the same (if any ) as any M14P.
If the smoke injector clamps are not perfectly sealed, smoke in the cockpit etc, exhaust extensions.
That is easy to overcome, welded fittings on the exhaust pipe with screw in nozzles.
But, can anybody tell me what injectors are best, one in each exhaust to produce a huge smoke system?
And where to buy? smoking airplanes perhaps?
Any info on good smoke for a M14P would be appriciated.
Next, engine life to overhaul.
As in any round engine, correct settings, slightly oversqaure, pull thru before starting being aware of hydralic lock and so on will extend the life of the engine.
And please dont forget regular oil changes.
I have been led to believe from many sources the the oil that the Russians used was nowhere as good as ours.
So one would expect that a better quality oil would extend the engine life, Would you not?
Now. Here in Australia the Australian Warbirds are the admin mob that set the rules for Limited and Experimental Aircraft rather than our CASA being directly involved.
So these guys say that they base the engine life etc to what the manufacturer states.
To me a little bit unfair as we dont fly them balls to the wall by ex numbers of training pilots or military blokes.
We even run a better oil at more stable temperatures than the Russians. No freezing cold conditions.
But in Australia we have to comply to first life. 750 hrs. Second life 500 hrs and then a final 3rd life of 500 hrs.
So theoritically we can only go to 1750 hrs on a M14P??????
As I also understand, in any other country, at the designated time, it is more of a simple inspection, carry out compression leakage test and if OK, randomly pull 3 pots and check.
In South Africa they run the 1st life to 1250 hrs before a simple IRAN.
Can I please have some feed back on these issues.
Thanks all,
Chris.
