Ek wil net graag weet hoe betroubaar is n single ignition, weet dat 2 mags beter is as 1, maar die engin self, weet nie of ek reg vra nie. Ons het n 503 Windless gekoop, single ignition, nou wil die mede eienaar niks weet van die engin nie, omdat dit single is.
Waardeer as iemand my van raad kan voorsien

Daar is niks verkeert met 'n Single Ignition 503 nie. Die enigste verskil is dat julle net een stel vonkproppe het in plaas van twee, wat 'n backup vir jou gee. As jy jou enjin gereeld diens, vonkproppe vervang elke 25uur, Filters skoonmaak, goeie olie en skoon brandstof gebruik en 'n goeie pre-flight inpspeksie doen, is daar geen rede dat jou engin nie jare diens kan gee nie.

Ek weet van single ingitions wat oor 1000uur sonder probleme loop.

1. diens gereeld
2. vlieg gereeld ( nie een of twee keer 'n jaar nie)
3. Oefen gereeld om te land sonder enjinkrag (net in geval)

NS. Verskoon my afrikaans

Morph says it all.

503SI is a fine motor, if she has been looked after than you should have absolutely no problems.

Baie dankie ouens vir julle advies!!!! Afrikaans is great, daars niks fout!!! ha ha ha ha

I did hundreds of hours on my single ignition Windlass without a hiccup. As Morph says as long as you change the plugs regularly, keep the airfilters clean and use a good oil you should be fine. All my engine outs have been in dual ignitions.

Enjoy

Know of quite a few dual ign engine outs

Heever, net twee woorde "bullet proof"
Ek het 'n Aquilla 582 dual ign en 'n Windlass 503 single ing. Die 503 si het nou by die 1000 ure gevlieg en ek sal NOU met hom Kaap toe vlieg. Die Aquilla 582 het na 130 ure 'n engine out gekry (die extra stel vonkproppe het NIKS gehelp nie).
Met die gevolg die 582 is heeltemal gebuig en gaan 'n paar rand vat om weer in die lug te kry.
Moenie laat enige iemand vir jou vertel 'n dual ignition is meer veilig as single ignition nie.

most engine outs occur through fuel starvation or engine seizure. Have never heard of an ignition problem to be the cause. anyone??

As I understand the main denefit of a dual ignition is more power? As can be seen in the rev drop when testing the mags.

The benefit of dual ignition is mainly for reliability (for what its worth). The drop in engine revolutions when you test the mags is due to the change in ignition timing i.e retarded timing.

I have never heard anything bad about a 503SI.
I have flown old single ig's and have had no problem sofar with the ignition at all.
The damper box did once fail and simulated ignition problems (low power, misfire, landing in the mielies) after the complete ignition system was overhauled between me and Andre from aviation engines with the problem persisting, Andre found the damping box faulty
I have heard of a few dual ig's that had problems and the exstra spark plug did not help at all.
Fly that SI and enjoy
