Greetings all from a very warm Charente.
Thought I'd post this as some colleagues have had problems with the factory C/L Saito 56.
Mine was a very late production model which I bought from the UK only a few months ago. The importer had decided to stop distributing Saito C/L engines and I was lucky enough to get one of the very last two example !
After my usual long winded running - in process I have had only two test flights so far. The first one was very 'average' [ wrong prop' etc ] and I had problems with control surface vibration.[ my stupid fault ].
This afternoon I went out with the following set-up :
13x6 prop' of Chinese origin . [ Hobbyking of Hong Kong , a very reliable outfit ! ].
20% total lube [ 18% synthetic with 2% added castor ]
5% only nitro.
No muffler pressure . [ I tried muffler pressure but the Saito wouldn't settle into a steady setting ! ].
Venturi insert had been REMOVED during running-in.
She easily was adjusted at 2 and a half open on the needle , holding a rock steady 8,400 which gave me around 5.3 second laps on my 65' lines.
Happy days !
I've read a lot about problems with the factory Saito c/l version but perhaps I'm just lucky ?
I'll probably adjust the needle one more notch next time but that'll be it.
Hope this helps ,
