Locozodiac - into liters that works out at 253ml. So I am about right for the oil mix.
Took my new 2.9m SIB out today and it was as much fun as the RC.
Peter - Engine was fine as suggested once it was pushing the SIB smoke died off and ran sweet as a nut.
With 2 big adults 33 stone combined it got on the plane once we shimmied up to the front. With just me it was an absolute hoot not giggled like a big girl in ages.
Just want to say big thanks to everyone who replied on this thread your help and advise has been really appreciated
