I need to learn Rotax 447- Sadler Vampire SV2

[farri]

I started off with a 503 with a wooden prop on the Austflight WB Drifter,when I was instructing and went to a 582 because the 503 didn`t have enough power on a hot day with the big guys in it.

 

I used up a total of 4, 582 engines.

 

Now that I`m not instructing anymore I`ve gone back to a new 503 with a 3 blade,ground adjustable prop,has more than enough power for me,started using it 4 months ago and have put "600 lts of unleaded" and 12lts of "Castrol 2T" through it and it runs beautifully,no sludge coming out the exhaust to date and the spark plugs look just right.

 

I`ve used Castrol Super TT in the 582s` but it didn`t burn completely and made a mess out the exhaust so I stoped using it.

 

I`m just not convinced that the more expensive oils are any better than what I`m using now.

 

Cheers,

 

Frank.
